Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
129 words
A shaped surgical needle adapted for suturing a wound, the needle comprising: a body: a bight in the body; a first arm and a second arm extending from the bight, each arm having a predetermined length and an end opposite the bight, said first arm having a length no greater than the length of said second arm; a gap distance between the end of said first arm and a point on said second arm located a distance from the bight corresponding to the length of said first arm, said gap distance being no greater than the length of said first arm; a sharpened point on the end of one of said arms; and a device at the end of the other of said arms for securing a suturing material.

Claim 5
Dependent Claim
17 words
The needle of claim 1 wherein the first arm has a length longer than the second arm.
Claim 6
Dependent Claim
