Abstract
Abstract A method and device for the placement of sutures and for the purpose of approximating tissue. A particular utility is effected in the approximation of the tissue separated by means of an endosurgical trocar being inserted into a body cavity. The invention provides for the loading of suture material including needles into the device, introduction and placement of the device into the body cavity, with the distal end having deployable needle guides, extending the needle guides either simultaneously or individually to the periphery of the wound, engaging the wound with the needle guides, driving the needles and suture material through the tissue to be approximated into a catch mechanism, retracting the needle guides and withdrawing the device, leaving a loop of suture material in the margin of tissue. The suture may then be tied to approximate the wound and excess suture material cut off. The invention also provides for the placement of sutures for the endoscopic approximation, fixation, and ligation of tissues within a body cavity including the driving and retrieval of needle and suture combinations, and facilitating the tying of knots.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
69 words
A needle catch made by the process comprising the steps of: selecting a substantially planar foundation having a first surface and a second surface; and forming at least one aperture in said substantially planar foundation, wherein a first surface lateral dimension of said aperture on said first surface of said foundation is larger than a second surface lateral dimension of said aperture on said second surface of said foundation.
Claim 2
Dependent Claim
69 words
A needle catch made by the process comprising the steps of: selecting a substantially planar foundation having a first surface and a second surface; and forming at least one aperture in said substantially planar foundation, wherein a first surface lateral dimension of said aperture on said first surface of said foundation is larger than a second surface lateral dimension of said aperture on said second surface of said foundation.
Claim 3
Dependent Claim
30 words
A needle catch made by the process defined in claim 1 wherein said step of forming at least one aperture further comprises the step of etching said substantially planar foundation.
Claim 4
Dependent Claim
36 words
A needle catch made by the process defined in claim 2 wherein said etching step further comprises the step of etching said substantially planar foundation from only one of said first surface or said second surface.
Claim 5
Dependent Claim
18 words
A needle catch made by the process defined in claim 1 wherein said aperture is a flexible aperture.
Claim 6
Dependent Claim
61 words
A needle catch comprising: a substantially planar foundation having a first surface and a second surface; and at least one aperture formed in said substantially planar foundation, wherein a first surface lateral dimension of said aperture on said first surface of said foundation is larger than a second surface lateral dimension of said aperture on said second surface of said foundation.
Claim 7
Dependent Claim
61 words
A needle catch comprising: a substantially planar foundation having a first surface and a second surface; and at least one aperture formed in said substantially planar foundation, wherein a first surface lateral dimension of said aperture on said first surface of said foundation is larger than a second surface lateral dimension of said aperture on said second surface of said foundation.
Claim 8
Dependent Claim
15 words
A needle catch as defined by claim 5 wherein said aperture is a flexible aperture.
Claim 9
Dependent Claim
54 words
A needle catch as defined by claim 5 further comprising a second aperture positioned adjacent to said at least one aperture wherein said second aperture has a first surface lateral dimension on said first surface of said foundation which is larger than a second surface lateral dimension on said second surface of said foundation.
Claim 10
Dependent Claim
81 words
A needle catch made by the process comprising the steps of: selecting a substantially planar foundation having a first surface and a second surface; and forming a plurality of adjacent flexible apertures in said substantially planar foundation, wherein a first surface lateral dimension of each of said plurality of flexible apertures on said first surface of said foundation is larger than a second surface lateral dimension of each of said plurality of flexible apertures on said second surface of said foundation.
Claim 11
Dependent Claim
81 words
A needle catch made by the process comprising the steps of: selecting a substantially planar foundation having a first surface and a second surface; and forming a plurality of adjacent flexible apertures in said substantially planar foundation, wherein a first surface lateral dimension of each of said plurality of flexible apertures on said first surface of said foundation is larger than a second surface lateral dimension of each of said plurality of flexible apertures on said second surface of said foundation.
Claim 12
Dependent Claim
32 words
A needle catch made by the process defined in claim 8 wherein said step of forming a plurality of adjacent flexible apertures further comprises the step of etching said substantially planar foundation.
Claim 13
Dependent Claim
36 words
A needle catch made by the process defined in claim 9 wherein said etching step further comprises the step of etching said substantially planar foundation from only one of said first surface or said second surface.
