摘要： A surgical device and method for removal of tissue, such as thrombus, from a vessel in the body. The device has a first tube with a distal open end and an inward directed stop and a second tube with an outward directed stop for engaging the inward directed stop and thereby regulating the relationship between a retrograde jet and the distal open end. Thrombus is dislodged, entrained, and broken into pieces which are evacuated through the first tube.

摘要： A technique for treatment of plaque deposits (120) on the arterial wall (110) of a patient. The technique employs a high pressure jet (126) of sterile saline solution directed at the plaque deposit. The high pressure jet is located at the distal end of a guide wire or catheter (12) which is advanced through the vascular system to the site of the plaque deposit. Optional removal of the debris is via an evacuation lumen within the catheter. This particular technique directs the high pressure jet of fluid distal to the distal tip of the guide wire or catheter. This permits treatment of arteries, which are totally occluded, because the device need not transit the lesion to be effective. Some applications will use the high pressure jet of fluid to open a sufficient passage within the occlusion to permit further dilatation using a balloon (58) integral to or passed over the device. An ultrasonic transducer array located adjacent the high pressure jet permits the attending physician to monitor the procedure. This may be particularly important for those embodiments for which the high pressure jet of fluid may be inadvertently directed toward the vessel wall at short range. The ultrasound device ensures that the jet of fluid is directed at plaque, rather than the native vessel.

摘要： A technique for ablation and removal of plaque (120) deposits from the arterial, venous, vascular graft or other tissue wall (110) of a patient. Ablation is accomplished by directing a high pressure jet (129) of sterile saline solution at the plaque deposit. The high pressure jet is located at the distal end of a catheter (12) which is advanced through the vascular system to the site of the plaque deposit. Removal of the debris is via an evacuation lumen (128) within the catheter. The arterial wall is protected from damage by the catheter design which directs the high pressure jet towards a portion of the distal end of the catheter which serves as a target. The distal end of the catheter is placed such that the plaque or other deposit to be ablated is positioned between the high pressure jet and the target. An optional ultrasonic transducer array (118) located adjacent the high pressure jet and the evacuation lumen permits the attending physician to monitor the procedure. A balloon (113) may be used to hold the catheter against the deposit allowing it to protrude into the ablation jet and be removed from the vessel.

摘要： A silicone/DACRON polyester composite vascular graft especially well suited as an arteriovenous (A-V) graft fistula for dialysis application. The graft has the ability to seal around needle puncture holes without externally applied pressure, excellent anti-kink, anti-crush and strength properties, and a smooth non-porous inner surface which reduces thrombus deposition and enhances the graft wall compliance or elasticity.
