Chondral defect repair
First Claim
Patent Images
1. A method of repairing a chondral defect of a bone, the method comprising:
- engaging a distal end of a delivery tube to the defect;
positioning only a distal tip of an awl outside the distal end of the delivery tube, the awl remaining in a longitudinal inner bore of the delivery tube;
microfracturing the bone with the distal tip of the awl;
positioning the distal tip of the awl into the delivery tube; and
delivering biological material into the defect through a longitudinal passage formed between an outer surface of the awl in the delivery tube and an inner surface of the inner bore of the delivery tube while the awl remains in the delivery tube.

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.

3. A method of repairing a chondral defect of a joint bone, the method comprising:
-
making an arthroscopic incision to the joint bone; exposing a chondral defect; engaging a distal tip of a delivery tube of a tissue repair device to the defect; exposing only a distal tip of an awl coupled to the tissue repair device outside the distal tip of the delivery tube and into the joint bone with the awl remaining in an inner bore of the delivery tube; microfracturing the bone underlying the defect with the distal tip of the awl; enclosing the distal tip of the awl into the inner bore of the delivery tube; delivering biological material through a longitudinal passage defined between an inner surface of the delivery tube and an outer surface of the awl with the awl in the inner bore of the delivery tube; removing the delivery tube from the incision; and closing the incision. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)

11. A method of repairing a chondral defect of a bone, the method comprising:
-
exposing a chondral defect; engaging a distal end of a delivery tube to the defect; moving a slider coupled to an awl to extend a distal tip of the awl beyond the distal end of the delivery tube to microfracture the bone with the distal tip of the awl with the awl remaining in the delivery tube; moving the slider to retract the distal tip of the awl into the delivery tube; and delivering biological material to the defect through a longitudinal passage formed between an outer surface of the awl and an inner surface of the delivery tube while the awl is in the delivery tube. - View Dependent Claims (12, 13, 14, 15, 16, 17)
