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.
Claims26
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.
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.
A catheter securement device, comprising a polymeric cuff including a plurality of bands, wherein each of the bands includes a collagen material.
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.
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.
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.
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.
