Abstract

Hemostatic clips and surgical strips made of deformable and preferably absorbable material have opposite elongate portions readily locked or secured together when clamped over a vessel or other bodily part. The elongate portions have opposite facing surfaces provided with a plurality of flexible members comprised of Velcro-like or similar entangling configurations, which become entangled when the surfaces are pressed together over the vessel or other bodily part. Other configurations include one or more strips of deformable material having surfaces provided with flexible members capable of entanglement to form clips or bands useful in a variety of different surgical procedures.

Claims

1. Absorbable hemostatic clip apparatus of elongate deformable and absorbable material in a generally U-shaped configuration and having a bail portion and a pair of arms extending from opposite ends of the ball portion, the pair of arms having facing inner surfaces provided with flexible members, the flexible members on the facing surface on a first of the pair of arms entangling with the flexible members on the facing surface of a second of the pair of arms when the facing surfaces of the first and second arms are pressed together to hold the pair of arms together.

2. Hemostatic clip apparatus according to claim 1, wherein the bail portion has opposite portions with facing inner surfaces provided with the flexible members.

3. Hemostatic clip apparatus according to claim 1, wherein the flexible members on the facing surface of the first of the pair of arms are in the shape of loops and the flexible members on the facing surface of the second of the pair of arms are in the shape of hooks.

4. Hemostatic clip apparatus according to claim 1, wherein the flexible members on the facing surfaces of the first and second arms are each comprised of a combination of loop and hook shapes.

5. Hemostatic clip apparatus according to claim 1, wherein the clip apparatus is comprised of an absorbable base member of generally U-shaped configuration and a thin layer of absorbable material mounted on an inside surface of the base member and having a surface opposite the base member which is comprised of the flexible members, the base member and the thin layer of absorbable material together forming the bail portion and the pair of arms.

6. Hemostatic clip apparatus according to claim 1, wherein the clip apparatus is comprised of a single integral member of generally U-shaped configuration forming the bail portion and the pair of arms.

7. An elongated deformable strip of absorbable material for use in surgical procedures and having at least one surface thereof provided with flexible entanglement elements of absorbable material.

8. An elongated deformable strip according to claim 7, wherein some of the entanglement elements are in the shape of loops and other ones of the entanglement elements are in the shape of hooks.

9. Absorbable apparatus for securing at least one bodily part therein comprising a pair of opposite strips of deformable and absorbable material, the strips having facing surfaces provided with flexible members, the flexible members on the facing surface of the first strip entangling with the flexible members on the facing surface of the second strip when the facing surfaces of the first and second strips are pressed together to hold the first and second strips together.

10. Apparatus according to claim 9, wherein the flexible members on the facing surface of the first strip are in the shape of loops and the flexible members on the facing surface of the second strip are in the shape of hooks.

11. Apparatus according to claim 9, wherein the flexible members on the facing surfaces of the first and second strips are each comprised of a combination of loops and hooks.
