Claim:
1. A uterine fibroid tissue removal device, comprising: a housing; an outer tube having a distal end and a proximal end, the proximal end of the outer tube supported by the housing, the outer tube configured for transcervical insertion into a uterus and having a tissue resection window located proximate to the distal end of the outer tube, the tissue resection window having a longitudinally oriented length; an inner tube disposed within the outer tube and configured to be translated and rotated relative to the outer tube during operation of the tissue removal device, the inner tube having an axial lumen; and a unitary distal tip member formed separately from the inner tube, wherein the inner tube is formed from a first material and the distal tip member is formed from a second material harder than the first material, the distal tip member being attached to a distal end of the inner tube such that an axial lumen of the distal tip member is in fluid communication with the inner tube axial lumen, and such that the distal tip member translates and rotates relative to the outer tube along with the inner tube during operation of the tissue removal device so that a distal facing open cutting end of the distal tip member in fluid communication with the axial lumen of the distal tip member translates across the tissue resection window of the outer tube to sever tissue extending therethrough, wherein an outer diameter of the distal tip member is greater than an outer diameter of the inner tube.
