摘要： A tissue removing catheter includes an apposition mechanism that selectively imparts an axially compressive load on the catheter body to bend the catheter and urge a tissue- removing element toward a blood vessel wall. The apposition mechanism can include one or more adjustment lines and an adjustment mechanism for selectively tensioning one of the adjustment lines to impart the compressive load on the catheter body. Two adjustment lines can have diametrically opposed positions and be wound onto a spool of the adjustment mechanism in opposite directions so that rotation of the spool simultaneously shortens one adjustment line and lengthens the other. The catheter body can have a more flexible bending segment adjacent the tissue-removing element to promote bending near the tissue-removing element operative to urge the tissue-removing element in apposition with the blood vessel.

摘要： A tissue-removing catheter (10) generally comprises a drive shaft (12) having opposite proximal and distal ends and configured for rotation about a longitudinal axis (A), and an abrasive burr (14) operatively connected to the distal end of the drive shaft (12) such that rotation of the drive shaft (12) about the longitudinal axis (A) imparts rotation to the abrasive burr (14). The abrasive burr (14) includes circumferentially spaced longitudinal struts (26) defining longitudinal slots (28) between adjacent struts (26), proximal (30) and distal hubs (32) secured to the respective proximal and distal ends of the longitudinal struts (26), and an abrasive exterior surface covering an abrasive longitudinal portion of each strut (26) extending from adjacent the proximal ends of the longitudinal struts (26) to adjacent the distal ends of the longitudinal struts (26). Proximal and distal longitudinal end portions of the longitudinal struts (26) adjacent the junctions of the longitudinal struts (26) and the respective proximal (30) and distal hubs (32) are free from the abrasive exterior surface.

摘要： A tissue-removing catheter includes a drive assembly operatively connected to a drive shaft to impart rotation and reciprocation to the drive shaft and thereby rotate and reciprocate a tissue-removing element of the catheter. The drive assembly includes a prime mover configured to generate a rotational drive force and a reciprocating rotor operatively connected to the prime mover to receive the rotational drive force. The rotor is also operatively connected to the drive shaft to impart rotation and reciprocation to the drive shaft. The drive assembly can include a stator configured to constrain rotation and reciprocation of the reciprocating rotor relative to an axis of the rotor. The rotor can define a race that extends around the rotor axis, and the stator can define one or more bearing projections that track through the race as the prime mover rotates the rotor about the rotor axis to drive reciprocation of the rotor.

摘要： A guidewire retrieval catheter includes a guidewire retrieval lumen extending lengthwise of a catheter body. An inflatable member at the distal end of the catheter body defines an inflation chamber for selectively receiving fluid to configure the inflatable member from deflated configuration to an inflated configuration. The inflatable member has an inner wall defining a guidewire retrieval cavity in communication with the guidewire retrieval lumen to facilitate insertion of the guidewire into the guidewire retrieval lumen when the inflatable member is in the inflated configuration. The guidewire retrieval catheter is used to retrieve a guidewire in a body lumen.
