1. A tissue repair device comprising:
- a handle having a slider;
a delivery shaft having proximal end and a distal end, the delivery shaft defining a longitudinal bore for delivering biological material, the proximal end of the delivery shaft coupled to the handle;
an awl received in the longitudinal bore of the delivery shaft, the awl having a distal tip configured for microfracturing, the awl moveable by the slider between a first retracted position in which the distal tip of the awl is inside the delivery shaft and a second extended position in which the distal tip of the awl is extended out of the distal end of the delivery shaft.

Abstract
A tissue repair device. The tissue repair device includes a tubular shaft having a longitudinal bore for delivering biological material to a soft tissue defect, and an awl having a distal end configured for microfracturing bone underlying the defect. The tubular shaft and the awl are movable relative to one another such that the awl is at least partially positioned within the longitudinal bore of the tubular shaft.

21. A tissue repair device comprising:
-
a handle having a slider; a delivery shaft defining a longitudinal bore extending from a proximal end to a distal end for use in delivering biological material, the proximal end coupled to the handle and the distal end having a distal tip configured for anchoring the distal tip on the tissue; an awl configured to be received in the longitudinal bore of the delivery shaft and having a distal tip configured for microfracturing, the awl movable by the slider between a first retracted position in which the distal tip of the awl is inside the delivery shaft and a second extended position in which the distal tip of the awl is extended out of the distal end of the delivery shaft; and wherein when the awl is positioned in the longitudinal bore of the delivery shaft, the awl and the delivery shaft define a longitudinal passage for flow of biological material, where the longitudinal passage is defined between an inner dimension of the tubular shaft and an outer dimension of the awl.
