Definitions
- the Vascular Descaler consists of two/three main units.
- a hand held small pressure pump is provided.
- a nozzle/ jet head A nozzle/ jet head.
- the catheter and jet head can also be a single disposable unit.
- the Vascular Descaler is less invasive than conventional treatments, requiring just two small incisions either side of diseased part of the vessel. Once the vessel has been exposed a clamp is then attached to the vessel at a point beyond the diseased area. This is to restrict blood flow while treatment is in progress. An incision is then made to gain entry to the vessel through which the catheter can be inserted. Fluid, is supplied by a conventional giving set, is fed through the hand held pressure pump and into the catheter. The amount of fluid and pressure at which it exit's the jet head must be variable and determined by the amount and structure of plaque needed to be removed from the vessel. The design of the exit holes on the jet head means the fluid will exit the jet head at approximately forty five degrees to the catheter. This will have a three fold effect.
- the whole procedure should be quick, clean and effective. It should also be less traumatic for the patient than some of the more conventional methods of treating vascular diseases.
- FIGURE 1 Shows a side angle of the pump.
- FIGURE 2 Shows the front of pump with catheter and re-usable jet head.
- FIGURE 3 Shows front of pump with single use catheter and jet head.
- FIGURE 4 Shows jet head and catheter inside a diseased vessel and the action of the fluid jets against the plaque and artery wall.
- FIGURE 5 Shows the jet head and catheter inside the diseased vessel with a forward facing fluid breaking up a blockage within the artery wall.
- FIGURE 6 Shows the jet head at the end of the procedure and the clamp closing the artery.
- the pump 1 comprises of a fluid inlet valve 2.
- the pump can be either air or electrically powered 3.
- the pump also has a flow pressure control 4, a pressure gauge 5 and an threaded outlet valve 6 to which the catheter is attached.
- the fluid can be seen within the pump chamber 13.
- the catheter 9 is stong yet flexible, designed to connect at one end with the pump outlet valve through a female threaded connector 8.
- a threaded male connector 10 at the end of the catheter enables the jet head 11 to be screwed on.
- Fig 3 shows a single use, disposable catheter and jet head as one single unit
- Fig 4 shows the catheter and jet head inside the vessel 14.
- the fluid 13 is being pumped, under pressure, through the catheter, exiting through the jet head and breaking the plaque 15 away from the artery wall.
- Fig 5 Shows the catheter and jet head inside the vessel.
- the jet head has a forward facing fluid jet which is breaking into a blockage within the vessel.
- Fig 6 Shows the jet head approaching the clamped section of the vessel 16.
- the catheter and jet head are then pulled back to the point of incision dragging the residue back with it. If there is still any substances within the artery the process is repeated.
