Abstract
Light from a small laser diode is inserted in a distal end (50) of a catheter (30) and passed through an optical fiber (10) that is either included in the lumen or incorporated into the wall of an invasive catheter tube during manufacture. The light is selected to be of a wavelength that is minimally absorbed by tissue, preferably in the range from about 620 nm to 1100 nm. 780 nm is preferably used as this is where the tissue absorption is near a minimum. The light passes out the end of the fiber (10) and through the tissue to the outside of the patient's skin where it is measured. The light pattern is observed by night vision goggles (70) that filter out other frequencies of light. The detected light permits location of the end of the fiber (10), the positional accuracy depending on the thickness of tissue between the fiber tip and the exterior of the body.

OPTICAL GUIDANCE SYSTEM FOR INVASIVE CATHETER PLACEMENT
GOVERNMENT SUPPORT
The present invention was supported by The U. S. National Institutes of Health under Grant No. NS-31465. The government may have certain rights in the invention.
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority to U.S. Provisional Patent Application No.
60/299,299, filed June 19, 2001.
FIELD OF THE INVENTION
The present invention relates to an optical guidance system and a method for insertion of endotracheal tubing, nasogastric tubing, feeding tubing, epidural catheters, central venous catheters, peripherally inserted central venous catheters, chest tubes plural catheters, and similar invasive catheters and tubes.
DESCRIPTION OF THE PRIOR ART
Determining the location of the end of a catheter inserted into patients for the purpose of providing nutrients or medications to specific locations within the body has been difficult. Currently, catheter placement is either done without visual guidance or, if the placement is particularly critical, it is done by x-ray, which can accurately determine the location of radio-opaque plastic materials used in making the tubing. However, multiple x-rays are often necessary. The necessity for multiple x-rays in order to locate the end of the inserted tubing is undesirable. An optical system that is convenient and easy to use and yet allows the end of the tubing to be quite accurately located without the use of x-rays is desired. Preferably, the position of the catheter tip may be directly observed during the insertion process and the position of the tip checked at any time thereafter.
Prior art catheter light delivery devices are known (e.g., Woodward et al;
5,947,958) that provide illumination of internal organs of a patient after insertion through, for example, the peritoneal wall. This illumination is to provide light for either imaging of the tissue surface or for delivering the light used in photodynamic therapy.
Such devices are not used for catheter placement.
Other light guides, such as Fontenot; 5,423,321, have multiple light guiding fibers of different lengths that are inserted into internal organs or vessels during surgery.
In the case of balloon catheters, such light guides are used to place the balloon catheter in positions where inflation of the balloon will occlude the vessel if that should become necessary. The light guide is an independent entity and observation is through the vessel wall such that visible light is sufficient, although near infra red light is indicated as decreasing the intensity of light that is required. A detection system is also described for determining when the surgical cutting tool approaches the vessel.
Vander Salm et al; 5,906,579 and Duhaylongsod et al; 6,113,588 similarly describe methods for visualizing balloon catheters through the vessel wall under surgical conditions. In these devices, the optical fiber is an independent entity and is preferably inserted through one lumen of a multilumen catheter. The disclosed devices are specifically disclosed for use in cardiothoracic surgery.
Such prior art light guides do not use a single fiber that is built into the structure of catheters with multiple different functions, are not directed primarily to localizing the tip of an inserted catheter during non-surgical procedures for endotracheal tubing, nasogastric tubing, feeding tubing, epidural catheterization, central venous catheterization, peripherally inserted central venous catheterizations, chest tubes plural catheterization, or with similar invasive catheters and tubes, and such prior art devices do not use only near infrared light since the vessels are not surgically exposed and visible light (blue through orange) provides insufficient penetration of the tissue.
Moreover, such prior art devices are relatively expensive and the optical components may require difficult FDA scrutiny since they may contact the patient. The present invention addresses these limitations in the prior art.
UMMARY OF THE INVENTION

The method is highly accurate for small children and for catheters near the skin surface of adults but may not be applicable to catheters placed within the body cavity of some large adults.

BRIEF DESCRIPTION OF THE DRAWINGS
An optical guidance system and method for insertion of endotracheal tubing, nasogastric tubing, feeding tubing, epidural catheters, central venous catheters, peripherally inserted central venous catheters, chest tubes plural catheters, and similar invasive catheters and tubes in accordance with the invention is further described below with reference to the accompanying drawings, in which:
Figure 1 illustrates a cross-section of a catheter with an integral optical fiber that is used in accordance with the invention to locate the tip of the inserted catheter.
Figure 2 illustrates a side view of the catheter of Figure 1.
Figure 3 illustrates the catheter of Figure 1 inserted into the body of a patient and the detection of the light from the tip of the catheter at the nearest spot of the patient's skin in accordance with the method of the invention.
DETAILED DESCRIPTION OF THE INVENTION
An optical guidance system in accordance with the invention includes a laser diode having a wavelength in the range of 620 nm to 1100 nm, preferably a 780 nm wavelength with an emission less than 2 nm wide and less than 5 mW in power that! is carried through a 150 micron (or less) core glass optical fiber to an "ST" optical connector at a distal end. As shown in Figure 1, the glass optical fiber 10 is embedded in (i.e., partially or completely surrounded by) the wall 20 of a catheter 30 having a catheter lumen 40. The optical fiber 10 runs the entire length of the catheter 30, and the unterminated end of the optical fiber 10 at the distal end 50 of the catheter 30 is adapted to be inserted into the patient as shown in Figure 2. The proximal end 60 is terminated with an ST optical connector (not shown) appropriate for connecting the optical fiber 10 with the laser diode (not shown) .
Conversely, the optical fiber 10 may be inserted into lumen 40 of the catheter 30 at its proximal end 60 and fed to the distal tip 50 of the catheter 30 and held in place so that light escapes from the distal end 50 once the catheter 30 is inserted into the patient.
The operator uses a detection system such as near infrared "night vision"
goggles 70 watch the progress of the catheter 30 from the site of entry to the chosen location. The distal end 50 of the catheter 30 is treated as a single light source and the diffuse rays from this light source are detected. A narrow pass (<10 nm at half height is preferred, although wider bandpass filters could be used) interference filter 80 with a center wavelength of 780 nm (for a light source of 780 nm) is used to cover the detector surface of the goggles 70. In general, contribution of other ambient lighting increases with increasing width of the optical filter bandpass. The value of less than 10 nm is selected to allow some variation in the laser diode wavelength and yet to minimize the amount of light other than that from the laser diode that passes through to the detector of the goggles 70. Of course, if other wavelength light were used, an appropriate interference filter centered about the other wavelength would be used.
Figure 3 illustrates the catheter 30 of Figures 1 and 2 inserted into the body of a patient vie a nasogastric catheter 30 and the detection of the light from the tip 50 of the catheter 30 at the nearest spot of the patient's skin in accordance with the method of the invention. In the example illustrated in Figure 3, night vision goggles 70 with an appropriate interference filter 80 thereon allow the operator to see the infrared light through the skin outside of the patient's stomach.
Those skilled in the art will appreciate that other designs of the optical guidance system for catheters in accordance with the invention could be constructed using different light sources and light detectors. While 780 nm light is suitable since tissue absorption is near a minimum at that wavelength, it would be possible, for example, to use an LED as a light source as long as the light provided was of appropriate wavelength and energy. In this case, a wider bandpass filter may be required on the detector (an LED light output is broader than that of the laser diode). Similarly, different detectors could be used, including photodiodes, photomultipliers, avalanche photodiodes, and microchannel plates.
When photodiodes or other single site detectors are used they could be moved over the surface of the tissue to detect the maximum in the specific light emitted from the optical fiber. The sensitivity of the measurement could be maximized by modulating the light at a specific frequency (such as 1000 Hz) and detecting only the photosignal of that frequency.
Another modification that would allow the operator to detect those cases in which the catheter had "doubled back" inappropriately would be to incorporate two optical fibers, one terminated about 5 centimeters before the tip and the other at the tip. The two could be distinguished by differences in modulation frequency and/or wavelengths of light.
In one variation of the detection system, the night vision goggle 70 could include a sensitive microchannel plate imager in a mini-display directly in front of one eye of the operator. This would allow the operator to look at either the patient or at the display as desired.
Although exemplary implementations of the invention have been described in detail above, those skilled in the art will readily appreciate that many additional modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of the invention. Any such modifications are intended to be included within the scope of this invention as defined by the following exemplary claims.
