Abstract
Abstract An expandable body suture that has a suture body that is formed in the manufacturing process over at least one pledget device that has an elongate shape with essentially a constant cross section along its mid-section and is of a diameter to fit snugly into a hole formed in a bone, ligament, tendon, or the like. The pledget device can be formed from a cloth, fabric or resinous material, is preferably resilient, is positioned in the suture body during manufacture or can be arranged on a cord or string whereover the suture body is formed during its manufacture as by weaving suture threads or strands thereover. For forming a hole in bone, ligament or tendon to receive the pledget device pulled therein, a needle or needles are secured to the suture body end or ends for forming the hole and pulling the suture body therethrough.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
88 words
An expandable body suture comprising, a suture body formed from conventional suture materials as an envelope to fully contain at least one pledget device that has an elongate body having a greater diameter than the diameter of the suture body adjacent to said pledget and is formed of a biocompatible material; a guide means having a cross sectional diameter that is equal to or slightly less than the diameter of said suture body portion and covered pledget device and is secured to an end of said suture body.
Claim 2
Dependent Claim
88 words
An expandable body suture comprising, a suture body formed from conventional suture materials as an envelope to fully contain at least one pledget device that has an elongate body having a greater diameter than the diameter of the suture body adjacent to said pledget and is formed of a biocompatible material; a guide means having a cross sectional diameter that is equal to or slightly less than the diameter of said suture body portion and covered pledget device and is secured to an end of said suture body.
Claim 3
Dependent Claim
41 words
An expandable body suture as recited in claim 1, wherein the suture body, in its manufacture, is formed by braiding, or otherwise forming, suture threads over the pledget device that has a substantially round, elliptical, square, rectangular or triangular cross section.
Claim 4
Dependent Claim
34 words
An expandable body suture as recited in claim 1, wherein the pledget device is arranged on a cord or string and the suture body is formed over the cord or string and pledget device.
Claim 5
Dependent Claim
27 words
An expandable body suture as recited in claim 3, wherein the pledget device is formed from a plastic or resinous material secured onto the cord or string.
Claim 6
Dependent Claim
22 words
An expandable body suture as recited in claim 1, wherein the pledget device is formed from a braided cloth or fabric material.
Claim 7
Dependent Claim
74 words
An expandable body suture as recited in claim 1, wherein the guide means is at least one needle that is secured at a needle base end onto a suture body end; and the suture body portion covering the pledget device is formed to have a diameter that is slightly greater than said needle to fit snugly into a hole formed by said needle in a bone, ligament, tendon, section of tissue, or the like.
Claim 8
Dependent Claim
24 words
An expandable body suture as recited in claim 1, wherein a plurality of pledget devices are maintained at spaced intervals within the suture body.
Claim 9
Dependent Claim
13 words
An expandable body suture as recited in claim 1, formed as a monofilament.
Claim 10
Independent Claim
128 words
A method for attaching a suture to a bone utilizing a suture having a body portion that is an envelope fitted over to contain an elongate pledget device with a suture end secured to a guide having a cross sectional diameter that is the same or slightly greater than the suture envelope and pledget device diameter consisting of, forming a hole through a bone or section of tissue to have a diameter that is approximately the diameter of the guide or less; fitting the guide into said bone or tissue hole and pulling said suture through said bone or tissue hole to where the pledget device contained in said suture travels in said bone or tissue hole; and maintaining said pledget device in said bone or tissue hole.
Claim 11
Independent Claim
128 words
A method for attaching a suture to a bone utilizing a suture having a body portion that is an envelope fitted over to contain an elongate pledget device with a suture end secured to a guide having a cross sectional diameter that is the same or slightly greater than the suture envelope and pledget device diameter consisting of, forming a hole through a bone or section of tissue to have a diameter that is approximately the diameter of the guide or less; fitting the guide into said bone or tissue hole and pulling said suture through said bone or tissue hole to where the pledget device contained in said suture travels in said bone or tissue hole; and maintaining said pledget device in said bone or tissue hole.
Claim 12
Dependent Claim
44 words
A method as recited in claim 9, wherein the guide is a needle and the end of the suture is secured to a blunt end of said needle, with a sharp end of said needle for use in forming the bone or tissue hole.
Claim 13
Dependent Claim
23 words
A method as recited in claim 9, wherein a plurality of pledget devices are fitted end to end in the suture body portion.
Claim 14
Dependent Claim
33 words
A method as recited in claim 9, wherein the bone or tissue hole is formed to have a slightly smaller diameter than the diameter of the suture body portion containing the pledget device.
