Abstract

A suture made of bioabsorbable material is disclosed having a central body member with a plurality of lateral members extending perpendicularly therefrom and in the same general plane with the central body member, each lateral member having a plurality of barb members extending at an acute angle therefrom, allowing the lateral members to be inserted laterally into two sides of a cut in body tissue so that the two sides are joined at an incision junction at the central body member and are retained securely and non-withdrawably in the body tissue by the barb members on such lateral members. Also disclosed is a method for utilizing the suture of this invention.

Claims

1. A suture assembly for lateral insertion in body tissue having a cut defined therein forming first and second sides of said cut, said suture for joining said first and second sides of said cut at a junction, comprising:

a central body member having first and second sides and first and second ends;

a plurality of lateral members each having an outer end disposed perpendicularly to said central body member on said first and second sides of said central body member, said lateral members are in parallel and planar relationship to one another and in planar relationship to said central body member, each lateral member for direct insertion within said cut into the side of said cut adjacent thereto; and

a plurality of barb members positioned on said lateral members, each extending at an acute angle to said central body member, said barb members preventing outward movement of said body tissue surrounding said lateral members away from said central body member after said lateral insertion of said lateral members into said first and second sides of said cut and positioning of said central body member at said junction of said first and second sides of said cut.

2. The suture of claim 1 wherein said suture is made of bioabsorbable material.

3. The suture of claim 1 wherein said plurality of barb members are formed from acute angular cuts defined in said plurality of lateral members directed away from said central body member.

4. The suture of claim 1 wherein each of said lateral members is comprised of a first part having first and second ends and a second part having first and second ends, said first parts being parallel to one another and forming a perpendicular to said sides of said central body member, each of said second ends of said first parts joined respectively to the first ends of said second parts, each of said second parts having a downward angular bend and each of said second ends of said second parts joined respectively to the sides of said central body member to dispose said central body member in a plane lower than the plane of said first parts of said plurality of lateral members.

5. The suture of claim 1 wherein said lateral members are rounded.

6. The suture of claim 1 wherein said ends of said lateral members are pointed.

7. The method of joining at a junction first and second sides of a cut defined in body tissue, comprising the steps of:

providing a suture made of bioabsorbable material having a central body member having first and second sides, a plurality of lateral members disposed perpendicularly to said central body member on each side of said central body member, said lateral members in parallel and planar relationship to one another and in planar relationship to said central body member, and a plurality of barb members positioned on said lateral members, each extending at an acute angle to said central body member;

laterally inserting said lateral members positioned along said first side of said central body member into said first side of said cut;

laterally inserting said lateral members positioned along said second side of said central body member into said second side of said cut; and

positioning said first and second sides of said cut at said junction at said central body member;

engaging the body tissue of said first and second sides of said cut by said positioning of said barb members thereagainst; and

preventing outward movement of said first and second sides of said cut away from said central body member by said engagement of said barb members against the body tissue of said first and second sides of said cut.
