DEVICES, SYSTEMS AND METHODS FOR PERFORMING ATHERECTOMY AND SUBSEQUENT BALLOON ANGIOPLASTY WITHOUT EXCHANGING DEVICES

摘要

The present invention is directed in various methods, devices and systems relating to providing a balloon on a sheath in combination with orbital atherectomy in order reduce the number of steps in the procedure. In certain embodiments, the balloon comprises adjunctive low pressure balloon for prevention of vessel trauma during dilatation.

主权项

1. A system for atherectomy and subsequent dilatation, comprising:
a rotatable drive shaft having an abrasive section and means for rotating and translating the drive shaft; a catheter collinear with the rotatable drive shaft and comprising
a distal end;an inflatable balloon mounted proximate the distal end of the catheter;a drive shaft lumen wherein the drive shaft is rotatable and translatable; andan inflation lumen separated from the drive shaft lumen; and an inflation media reservoir comprising an inflation medium, wherein the inflation lumen is in fluid communication with the inflation lumen and the inflatable balloon.
