Atherektomiesystem mit einer Kupplung.

摘要

An atherectomy system for cutting an obstruction (13) in a patient's vessel, comprising a flexible guide-wire (14) insertable into the vessel, a flexible rotary catheter (15) being rotatably disposed and insertable into the vessel, over the flexible guide-wire (14), cutting means (16) for cutting the obstruction (13) at a distal end of the flexible rotary catheter (15), coupling means (17) at the proximal end of the flexible rotary catheter (15) for engaging a drive means (120) and at least one torque limiting clutch (18) interposed between the drive means (120) and the cutting means (16), limiting the torque transmitted distally.
