Abstract
Abstract A suturing apparatus comprises an elongated body, at least one arms movable relative to the elongated body and at least one needle movable relative to the elongated body. The arm releasably holds an end portion of a length of suture. The arm has a sharp end portion adapted to pierce an inner surface of a wall of a biological structure and pass an end portion of the suture through the inner surface. The needle is adapted to pierce the inner surface of such biological structure at a location proximal to the location where the end portion of the suture was inserted. The needle captures an end portion of the suture from the arm and draws the end portion of the suture back through the inner surface. The end of the suture is then drawn out of the biological structure by removing the elongated body.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
194 words
A suturing device for applying a suture, comprising: an elongated body; at least one arm having a suture mounting portion to releasably hold a portion of said suture, said arm being mounted to cause an end portion of said arm to move (i) away from said elongated body from a first position to a second position and (ii) towards said elongated body from the second position to the first position, said end portion of said arm being adapted to penetrate tissue as the arm moves away from said elongated body to said second portion while holding said portion of the suture during such movement; and at least one needle having a distal end, said needle mounted to move relative to said elongated body, said distal end of said needle movable from a first position adjacent to said elongated body to a second position adjacent said suture mounting portion of said arm when said arm is in said second position; wherein said distal end of said needle is adapted to capture said portion of the suture from the suture mounting portion of the arm and draws said portion of said suture toward said elongated body.
Claim 2
Dependent Claim
194 words
A suturing device for applying a suture, comprising: an elongated body; at least one arm having a suture mounting portion to releasably hold a portion of said suture, said arm being mounted to cause an end portion of said arm to move (i) away from said elongated body from a first position to a second position and (ii) towards said elongated body from the second position to the first position, said end portion of said arm being adapted to penetrate tissue as the arm moves away from said elongated body to said second portion while holding said portion of the suture during such movement; and at least one needle having a distal end, said needle mounted to move relative to said elongated body, said distal end of said needle movable from a first position adjacent to said elongated body to a second position adjacent said suture mounting portion of said arm when said arm is in said second position; wherein said distal end of said needle is adapted to capture said portion of the suture from the suture mounting portion of the arm and draws said portion of said suture toward said elongated body.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
29 words
The suturing device of claim 1 , wherein the arm is hingedly mounted to an actuating rod, said actuating rod being movable within a lumen of the elongated body.
Claim 5
Dependent Claim
18 words
The suturing device of claim 1 , wherein the end portion of the arm includes a pointed tip.
Claim 6
Dependent Claim
61 words
The suturing device of claim 1 , comprising: first and second arms each having a suture mounting portion to releasably hold an end portion of a suture; and first and second needles adapted to capture the end portions of the suture from the suture mounting portions of the first and second arms and draw the end portions of the suture proximally.
Claim 7
Dependent Claim
24 words
The suturing device of claim 5 , wherein the first and second arms when in their second position are substantially parallel to one another.
Claim 8
Dependent Claim
27 words
The suturing device of claim 5 , wherein the first and second arms when in their second position form an angle that is less than 180 degrees.
Claim 9
Dependent Claim
19 words
The suturing device of claim 5 , wherein the first and second arms each have two suture mounting portions.
Claim 10
Dependent Claim
18 words
The suturing device of claim 8 , wherein the two suture mounting portions on each arm are side-by-side.
Claim 11
Dependent Claim
23 words
The suturing device of claim 8 , wherein one of the two suture mounting portions on each arm is distal to the other.
Claim 12
Dependent Claim
