Patent ID: 8777956

Claim:
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.
