Abstract
Abstract A meniscal tissue repair device includes an elongate body having a pointed distal tip. A plurality of lateral grooves is disposed along the body. Grooves disposed near the distal tip of the device are angled to open proximally and grooves disposed near the proximal end are angled to open distally. A torn meniscus can be repaired using the meniscal repair device by loading the meniscal repair device into an applicator, and inserting the barrel of the applicator through an incision in the knee at a location proximal and perpendicular to the tear in the meniscus. The applicator is actuated to drive the repair device distally into the meniscus across the tear. The distal travel of the repair device is limited by the distally-opening grooves of the repair device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
A tissue repair device comprising an elongate body having a pointed distal tip, a proximal end, opposing sides, a central axis, and a plurality of lateral grooves disposed along each of the opposing sides of the body, the grooves forming a regular pattern, the pattern on one side of the elongate body being offset from the pattern on the opposite side of the body, the grooves having a crescent shape, wherein grooves disposed near the distal tip of the device are angled to open proximally and grooves disposed near the proximal end are angled to open distally, and wherein surfaces of adjacent grooves converge at an acute angle to form sharp edges for anchoring against tissue, the body being configured for the repair of tissue.
Claim 2
Dependent Claim
125 words
A tissue repair device comprising an elongate body having a pointed distal tip, a proximal end, opposing sides, a central axis, and a plurality of lateral grooves disposed along each of the opposing sides of the body, the grooves forming a regular pattern, the pattern on one side of the elongate body being offset from the pattern on the opposite side of the body, the grooves having a crescent shape, wherein grooves disposed near the distal tip of the device are angled to open proximally and grooves disposed near the proximal end are angled to open distally, and wherein surfaces of adjacent grooves converge at an acute angle to form sharp edges for anchoring against tissue, the body being configured for the repair of tissue.
Claim 3
Dependent Claim
25 words
The tissue repair device of claim 1, wherein the elongate body has opposing sides, and the grooves are disposed on opposite sides of the body.
Claim 4
Dependent Claim
35 words
The tissue repair device of claim 2, wherein the grooves form a regular pattern, the pattern on one side of the elongate body being offset from the pattern on the opposite side of the body.
Claim 5
Dependent Claim
32 words
The tissue repair device of claim 1, wherein the number of grooves disposed near the distal tip of the device is less than the number of grooves disposed near the proximal end.
Claim 6
Dependent Claim
25 words
The tissue repair device of claim 1, wherein the grooves are formed at an angle of about 30 ° with respect to the central axis.
