Abstract
A catheter (10) including a shaft (14), a balloon (12) positioned at the distal end of the shaft, and at least one scoring wire (30) to score a vascular lesion. A distal end portion of the scoring wire is retractable and includes an atraumatic tip (32). The device includes an actuator (40), such as a thumb wheel (44), for advancing the at least one scoring wire to a location such that a portion thereof is alongside the balloon, thereby allowing for selective use in a scoring configuration. When the balloon expands when fluid is delivered to the balloon through the inflation lumen, this expansion pushes the scoring wire against the vascular lesion.
Claims20
A scoring balloon catheter, comprising:
- a shaft having a proximal end section and a distal end section;
- an inflatable balloon mounted on the distal end section of the shaft;
- and
- at least one scoring wire partially located within the shaft proximal of the inflatable balloon and including an atraumatic tip adapted for translating in a longitudinal direction to position a portion of the at least one scoring wire alongside the balloon.
A scoring balloon catheter, comprising:
- a shaft having a proximal end section and a distal end section;
- a hub connected to the proximal end section of the shaft;
- an inflatable balloon mounted on the distal end section of the shaft;
- and
- at least one scoring wire;
- an actuator supported by the hub for advancing and retracting the at least one scoring wire in a longitudinal direction such that a portion thereof extends alongside the inflatable balloon.
A scoring balloon catheter, comprising:
- a shaft having a proximal end section and a distal end section;
- an inflatable balloon mounted on the distal end section of the shaft;
- at least one scoring wire;
- and
- a rotary actuator for advancing and retracting the at least one scoring wire in a longitudinal direction such that a portion of the at least one scoring wire extends alongside the inflatable balloon.
