Abstract
Abstract A flexible, elongated suture passing device or shuttle capable of advancing monofilament or multi-stranded suture material to a remote work site. The suture shuttle is formed of a plurality of woven or braided fiber strands which are coated, over all but a central portion of the strands, with a material having a flexible exterior surface. A part of the central portion of the strands is formed into an eyelet for receiving a suture therethrough. A method is disclosed wherein one end of the suture shuttle is advanced to a work site until the eyelet passes through the tissue at the work site. This enables suture to be passed through the eyelet so the shuttle may be withdrawn to pass the suture back through the tissue to be sutured. Repeating this process brings any desired number of suture leads through the tissue so a knot may be tied.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
67 words
A suture passing device comprising: a flexible, elongated, wire-like member having a predetermined length, said flexible wire-like member formed of a plurality of braided wires or fibers; a flexible eyelet member secured to said flexible wire-like member intermediate the ends of said wire-like member; a cover over said wire-like member of each side of said eyelet, said cover formed of a material having a flexible exterior surface.
Claim 2
Dependent Claim
67 words
A suture passing device comprising: a flexible, elongated, wire-like member having a predetermined length, said flexible wire-like member formed of a plurality of braided wires or fibers; a flexible eyelet member secured to said flexible wire-like member intermediate the ends of said wire-like member; a cover over said wire-like member of each side of said eyelet, said cover formed of a material having a flexible exterior surface.
Claim 3
Independent Claim
252 words
A method of suturing tissue endoscopically comprising the steps of: (a) introducing a primary cannula into a selected body site; (b) introducing a suture into said primary cannula and attaching same in a substrate at a selected suture site such that two suture leads pass from said suture site through said primary cannula; (c) introducing a secondary cannula adjacent to said primary cannula; (d) grasping said two suture leads and pulling them back through said primary cannula into the work space adjacent said suture site and then out from said secondary cannula; (e) providing a flexible, elongated wire-like member having a predetermined length and an eyelet secured to said flexible wire-like member intermediate its ends; (f) passing one end of said flexible wire-like member through selected tissue to be sutured to said suture site; (g) advancing said one end of said flexible wire-like member through said tissue and out from said secondary cannula until said eyelet exits from said secondary cannula while the other end of said flexible wire-like member is accessible from said primary cannula; (h) threading one of said suture leads through said eyelet; (i) withdrawing said other end of said flexible wire-like member and said threaded suture lead from said primary cannula to thereby pass said threaded suture lead through said tissue; (j) removing said threaded suture lead from said eyelet; (k) repeating steps f through j until both suture leads extend out of said primary cannula outside said body site; (1) tying a knot with said suture leads.
Claim 4
Independent Claim
252 words
A method of suturing tissue endoscopically comprising the steps of: (a) introducing a primary cannula into a selected body site; (b) introducing a suture into said primary cannula and attaching same in a substrate at a selected suture site such that two suture leads pass from said suture site through said primary cannula; (c) introducing a secondary cannula adjacent to said primary cannula; (d) grasping said two suture leads and pulling them back through said primary cannula into the work space adjacent said suture site and then out from said secondary cannula; (e) providing a flexible, elongated wire-like member having a predetermined length and an eyelet secured to said flexible wire-like member intermediate its ends; (f) passing one end of said flexible wire-like member through selected tissue to be sutured to said suture site; (g) advancing said one end of said flexible wire-like member through said tissue and out from said secondary cannula until said eyelet exits from said secondary cannula while the other end of said flexible wire-like member is accessible from said primary cannula; (h) threading one of said suture leads through said eyelet; (i) withdrawing said other end of said flexible wire-like member and said threaded suture lead from said primary cannula to thereby pass said threaded suture lead through said tissue; (j) removing said threaded suture lead from said eyelet; (k) repeating steps f through j until both suture leads extend out of said primary cannula outside said body site; (1) tying a knot with said suture leads.
Claim 5
Dependent Claim
83 words
A method according to claim 2 wherein said step of passing one end of said flexible wire-like member through selected tissue further comprises: providing a suture punch having a hollow needle at its distal end and means for passing said flexible wire-like member from the proximal end of said punch through said hollow needle; introducing said punch into said primary cannula; piercing said selected tissue with said hollow needle; and advancing said flexible wire-like member until it passes out of said hollow needle.
Claim 6
Dependent Claim
11 words
A method according to claim 2 wherein said suture is multi-stranded.
