Abstract

Disclosed is a tissue removal device having an outer tube with a resection window and an inner tube disposed within the outer tube. The inner tube is slidable and rotatable relative to the outer tube so that the distal end of the inner tube moves back and forth across the resection window to sever tissue extending therethrough. The inner tube may be driven to rotate at a speed of at least about 1100 rpm, to axially translate at a rate of at least about 1.5 cps, and with an advance ratio of no more than about 0.25. The drive system for controlling axial reciprocation and rotation of the inner tube may be totally mechanical.

Claims (6)

1 . A tissue removal device comprising:

(a) a housing;

(b) an outer tube, the outer tube being fixed to the housing and extending distally therefrom, the outer tube including a resection window;

(c) an inner tube disposed within the outer tube, the inner tube being slidable and rotatable relative to the outer tube so that the distal end of the inner tube moves back and forth across the resection window to sever tissue extending therethrough; wherein

the inner tube is driven to rotate at a speed of at least about 1100 RPM; to axially translate at a rate of at least about 1.5 cps; and with an advance ratio of no more than about 0.25.

2 . A tissue removal device with a totally mechanical drive system wherein drive power is provided by a mechanically stiff flexible drive member and rotational and axial reciprocal movements are provided by a mechanical drive transmission with an advance ratio of no more than about 0.25.
