Abstract

Implantable catheters including one or more cuffs are described herein. At least one of the cuffs may include a collagen material, such as Avitene® collagen. The catheter may include a combination of collagen cuffs and collagen-free polymeric cuffs. Various methods for the fabrication of collagen cuffs are also disclosed herein.

Claims

1. A catheter securement device, comprising a plurality of cuffs positioned along a length of a catheter, including a first cuff configured for tissue ingrowth and a second cuff including a collagen material.

2. The catheter securement device according to claim 1, wherein the collagen material comprises water soluble partial hydrochloric acid salt of purified bovine corium collagen.

3. The catheter securement device according to claim 2, wherein the form of the collagen material includes flour, foam, mesh, slurry, fibers, filaments, or yarn and combinations thereof.

4. The catheter securement device according to claim 1, wherein the plurality of cuffs comprises a first polymeric cuff and a second collagen cuff.

5. The catheter securement device according to claim 4, wherein the first polymeric cuff is positioned in close proximity to the second collagen cuff.

6. The catheter securement device according to claim 4, wherein the first polymeric cuff is in contact with the second collagen cuff.

7. The catheter securement device according to claim 4, wherein the second collagen cuff is positioned distally of the first polymeric cuff.

8. The catheter securement device according to claim 4, wherein the first polymeric cuff comprises a polyester material.

9. The catheter securement device according to claim 4, further comprising a third polymeric cuff, wherein the second collagen cuff is positioned between the first and third polymeric cuffs.

10. The catheter securement device according to claim 4, wherein the second collagen cuff is slidably positioned on the catheter.

11. The catheter securement device according to claim 10, further comprising a fillet, wherein the second collagen cuff is positioned between the fillet and the first polymeric cuff.

12. A catheter securement device, comprising a cuff including an inner layer and an outer layer positioned coaxially over the inner layer, the inner layer including a polymeric material and the outer layer including a polymeric material and a collagen material.

13. The catheter securement device according to claim 12, wherein the inner layer comprises a polyester felt and the outer layer comprises a collagen foam.

14. The catheter securement device according to claim 12, wherein the outer layer polymeric material is absorbable.

15. A catheter securement device, comprising a polymeric cuff including a plurality of bands, wherein each of the bands includes a collagen material.

16. A method for implanting a catheter, comprising:

placing a catheter including a cuff configured for tissue ingrowth in a subcutaneous tunnel; and

releasing collagen into the subcutaneous tunnel from a location along the length of the catheter distal to the cuff.

17. A method of creating a catheter securement device, comprising:

providing a polymeric member;

incorporating a collagen material into the polymeric member; and

forming the member into a cuff.

18. The method according to claim 17, wherein the collagen material is a collagen mesh, and wherein the incorporating includes wrapping the mesh about the cuff.

19. The method according to claim 17, wherein the polymeric member is a sheet of polyester felt and the collagen material is a water soluble partial hydrochloric acid salt of purified bovine corium collagen slurry, the incorporating comprising pre-wetting the felt and pouring the slurry onto the pre-wetted felt.

20. The method according to claim 19, wherein the incorporating further comprises freeze-drying the felt following the pouring.

21. The method according to claim 20, wherein the freeze-drying comprises compressing the felt.

22. The method according to claim 19, wherein the incorporating further comprises creating a plurality of cavities in the felt prior to pouring.

23. The method according to claim 17, wherein the polymeric member is a sheet of polyester felt and the collagen material includes a plurality of filaments, fibers or yarn, and wherein the incorporating comprises sewing the filaments, fibers or yarn into the felt.

24. A method of retarding the flow of blood from a wound, comprising providing a capsule containing a collagen material encapsulated within a dissolvable container and inserting the capsule into an open wound such that the collagen material is released from the container when the container dissolves.

25. A method of attaching a catheter securement device to a catheter, comprising:

disposing a hydrogel material over a desired region of a catheter; and

positioning a polymeric cuff over the hydrogel material.

26. The method according to claim 25, further comprising creating slits in the polymeric cuff.
