Definitions
- This invention concerns optical fibre catheters in general for medical and surgical use, and refers in particular to an optical fibre catheter for thermal ablation using laser.
- Prior Art
- catheters for performing thermal ablation in various parts or organs of the body reached by passing though ducts or natural vessels are also well known among these catheters.
- optical fibres for thermal ablation using laser rays are also well known among these catheters.
- the optical fibres in these catheters extend, depending on the length of the catheter, from a proximal connector connectable to a laser unit as far as the distal end where the optical fibres protrude to irradiate the part to be treated.
- the required irradiation takes place through the free ends of the optical fibres and in essence it is directed only forwards, frontward of the distal part of the catheter.
- Some thermal ablation operations using laser rays may however require in particular radial irradiation, like a circular crown around the catheter, an action which present well known catheters are unable to perform.
- an optical fibre catheter connectable to a laser source unit, wherein the distal ends of the optical fibres are truncated obliquely and associated in addition with an arch shaped reflecting surface metal point placed on the distal end of the catheter, so that the laser rays flowing along the optical fibres are reflected laterally towards the outside of the catheter itself.
- the catheter can also house a longitudinal duct.
- this duct can possibly be used for inserting and moving a guide wire or for housing at least one additional optical fibre also for irradiating immediately in front of the catheter.
- Fig. 1 is a view of the optical fibre catheter
- Fig. 2 is an enlarged of a side view of the distal part of the catheter in Fig.1 ;
- Fig. 3 is further enlarged longitudinal section view of the distal part of the catheter shown in Fig.2
- Fig. 4 is a cross section view in direction of arrows A -A on Fig. 2 of a four fibre catheter
- Fig. 5 is a view of a similar cross section of a six optical fibre
- Fig. 6 is a cross section view of the metal point in direction of
- the catheter proposed herein comprises of a flexible central
- optical fibres 12 the number of which can be
- optical fibres is four and six, respectively.
- the centre element 1 1 can be solid, but tubular is preferable so as
- the optical fibres 12 extend from a proximal end 14 almost
- a flexible housing sheath 16 are enclosed in a flexible housing sheath 16 and can be held in position by
- a filler or bonding agent such as a resin
- the optical fibres 12 can be connected by
- optical fibres 12 are encompassed by a blocking ring 18 in close proximity to their distal part 15; such ring, for example, may be made
- the optical fibres 12, in their distal part 15, that is in the section beyond the blocking ring 18, have a portion exposed towards the outside and are cut at a slant so as to finish in an oblique terminal 19.
- the oblique end part 19 of each optical fibre is slanting from the outside towards the axis of the centre element and associated with a nearby reflecting surface 20 which is also slanting.
- This reflecting surface 20 is formed by a metal ogival or similar shaped point 21, attached to the distal end of the central element 11. In this way, the laser rays which travel along the optical fibres 12 are reflected and emitted laterally towards the external of the catheter, at the distal end of the latter, around it, irradiating the surrounding part to be treated by thermal ablation.
- the slant angle of the oblique end part 19 of each optical fibre 12 and the same applying to reflecting surface 20 can be chosen as required on the basis of the total or partial reflection needed.
- This slant angle can be the same for all the optical fibres of the same catheter or can vary in the case of some optical fibres compared to the others, in this way the emission field of the laser rays can be oriented differently according to the requirements for irradiation of the part needing treatment.
- the catheter has a longitudinal duct 13
- this can be used to receive a guide wire or also for housing an additional optical fibre, nor shown here, with its own end piece at the front of the metal point in order to meet irradiation needs, where required, also in front of the catheter for front thermal ablation.
