1. A tissue repair device comprising:
- a tubular shaft defining a longitudinal bore extending between a proximal end and a distal end of the tubular shaft for delivering biological material to a soft tissue defect; and
an awl having a body of constant cross-section and a distal end configured for microfracturing bone underlying the defect, wherein the awl is movable between a first retracted position in which the distal end of the awl is fully within the longitudinal bore and a second extended position in which the distal end of the awl is outside the longitudinal bore of the tubular shaft and wherein the longitudinal bore has an inner diameter substantially equal to an outer diameter of the body of the awl, the body of the awl forming an outer longitudinal groove such that a longitudinal passage is defined between the longitudinal bore of the tubular shaft and the longitudinal groove of the awl when the awl is inside the longitudinal bore in the first retracted position, the longitudinal passage extending to a distal end of the tubular shaft for flow of biological material.

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.

8. 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; and 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 and wherein the longitudinal bore of the delivery shaft has an inner diameter substantially equal to an outer diameter of the awl, the awl having an outer longitudinal groove such that a longitudinal passage is defined between the longitudinal bore of the shaft and the groove for flow of biological material when the awl is inside the longitudinal bore in the first retracted position, the longitudinal passage extending to the distal end of the delivery shaft. - View Dependent Claims (9, 10, 11, 12)

13. 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 longitudinal bore have a constant inner diameter, 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 access port communicating with the longitudinal bore of the delivery shaft for delivering biological material, wherein the access port is outside the handle adjacent the distal end of the handle; an awl configured to be received in the longitudinal bore of the delivery shaft and having a distal tip configured for microfracturing, the awl having a constant outer diameter to the distal tip and an outer longitudinal groove, the outer diameter of the awl substantially equal to the inner diameter of the longitudinal bore, 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 in the first retracted position with the distal tip of the awl fully inside 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 the longitudinal bore of the tubular shaft and the longitudinal groove of the awl, the longitudinal passage extending from the access port to the distal end of the delivery shaft. - View Dependent Claims (20)

14. A tissue repair device comprising:
-
a handle having a retracting mechanism; a tubular shaft extending from a proximal end to a distal end and defining a longitudinal bore, the proximal end coupled to the handle; and an awl received in the longitudinal bore of the tubular shaft, the awl having a distal tip configured for microfracturing tissue, wherein the awl is movable by the retracting mechanism between a first retracted position in which the distal tip of the awl is inside the longitudinal bore of the tubular shaft, and a second extended position in which the distal tip of the awl is extended out of the distal end of the tubular shaft to allow microfracturing of the tissue, wherein the longitudinal bore has an inner diameter substantially equal to an outer diameter of the awl and wherein a longitudinal passage is defined between the longitudinal bore and an outer longitudinal groove of the awl when the awl is inside the longitudinal bore in the first retracted position, the longitudinal passage extending to the distal end of the tubular shaft for delivering biological material along the tubular shaft to the distal end of the tubular shaft. - View Dependent Claims (15, 16, 17, 18, 19)
