摘要： A dilator (100) for expanding a vessel incision to assist insertion of a catheter thereinto and having a distal end (104) and a proximal end (106). The dilator has two portions (110, 210) that are assembled together at a hinge (1 12, 212) permitting angled-apart proximal ends (122, 222) of the two portions at the proximal end (106) to be squeezed together about the hinge which slightly spreads apart the respective distal ends (114, 214) of the two portions to enlarge the incision into the vessel. A spring (150) biases apart the proximal ends of the two portions to maintain the two distal ends (114, 214) together until pried apart as desired to dilate the vessel incision.
摘要翻译： 1.一种用于扩张血管切口以辅助将导管插入其中并具有远端（104）和近端（106）的扩张器（100）。扩张器具有在铰链（112,212）处组装在一起的两个部分（110,210），允许在近端（106）处两个部分的角度分开的近端（122,222）被挤压在一起约铰链将两个部分的各个远端（114,214）稍微扩展，以将切口扩大到容器中。弹簧（150）将两个部分的近端分开偏置，以将两个远端（114,214）保持在一起，直到根据需要分开以扩张血管切口。

摘要： A multilumen catheter assembly (100) including a catheter (102) having an elongated body (108) having a proximal end (104) and a distal end (106) and a first lumen (122) with a first distal opening (126) disposed at its distal end, and a second lumen (124) connected to the first lumen but extending distally therebeyond to a second distal opening (130). A protector (120) is adjoined to the second lumen (124) distally of the first distal opening (126) and extends radially and proximally to a free proximal edge (134) to engage the vessel walls radially about the first distal opening to center the catheter (102) within the vessel to prevent occlusion of the first distal opening (126). A plurality of openings (136) extend through the protector (120) to permit blood flow therethrough.

摘要： A cutting balloon catheter assembly (100) including a dual lumen catheter (130) having a distal end (134), an inflation/deflation lumen (138) and a second or guidewire lumen (136). The assembly further includes an inflatable balloon (110) having an interior cavity (116) and an expandable covering (120) disposed about the balloon wherein the covering has an array of cutting edges. In the assembly, the balloon (110) is fixedly connected to the distal end (134) of the catheter and the interior cavity (116) of the balloon (110) is in fluid communication with the first lumen (138) of the catheter (130). A method of removing obstructions (149) from vessel walls (154) using the present invention is also disclosed wherein the cutting edges abrade the stenoses, plaque or lesions along the vessel walls, when the catheter assembly is reciprocally moved longitudinally or rotationally after inflation of the balloon.

摘要： A multiple catheter assembly is provided (100). The assembly includes a first catheter (110) having a first proximal end region (112), a first distal end region (114) terminating in a first distal tip (116), and an outer surface (120) defining at least a first lumen (122) extending longitudinally therethrough between a first distal (118) and a first proximal opening. The assembly also includes a second catheter (130) having a second proximal end region (132), a second distal end region (134) terminating in a second distal tip (136), and a second outer surface (140) defining at least a second lumen (142) extending longitudinally therethrough between a second distal (138) and a second proximal opening. The first lumen and the second lumens are independent from each other for faciliting simultaneous flow in opposite directions. The outer surfaces of the first and second catheters are releasably joined for allowing the first and second distal tips and first and second proximal end regions to be at least partially longitudinally split from each other. A method of inserting the catheter assembly is also provided.
