Catheter retention device
View Patent ↗Embodiments provide catheter retention devices such as catheter clips that may be used to stabilize a vascular access catheter during a procedure, particularly a radial access procedure. The catheter clips may include a frame that includes a first frame member portion, a second frame member portion hingeably coupled to the first frame member portion, the first and second frame member portions defining a first aperture therebetween, and a base member extending from the second frame member; and an inner gripping membrane that includes a first inner gripping membrane portion coupled to the first frame member portion and a second inner gripping portion coupled to the second frame member portion, wherein the first and second inner gripping portions define a second aperture within the first aperture.
1. A clip for stabilizing a catheter, comprising:
a frame member comprising:
a first frame member portion;
a second frame member portion hingeably coupled to the first frame member portion, the first and second frame member portions defining a first aperture therebetween; and
a base member extending from the second frame member, the first and second frame members and base member being formed from a rigid or semi-rigid material; and
an elastomeric inner gripping member extending inwardly from the frame member, comprising:
a first elastomeric inner gripping member portion coupled to the first frame member portion, the first elastomeric inner gripping member portion comprising a first elastomeric membrane element and a first elastomeric reinforcing element; and
a second elastomeric inner gripping member portion coupled to the second frame member portion, the second elastomeric inner gripping member portion comprising a second elastomeric membrane element and a second elastomeric reinforcing element; wherein the first and second elastomeric inner gripping member portions define a second aperture within the first aperture.
2. The clip of claim 1 , wherein the base member is adapted to selectably couple the clip to a substrate.
3. The clip of claim 2 , wherein the base member comprises an adhesive patch.
4. The clip of claim 1 , wherein the second aperture is sized to receive a vascular catheter.
5. The clip of claim 1 , wherein the first and second elastomeric reinforcing elements provide sufficient gripping force to prevent rotational and longitudinal motion of a catheter gripped within the second aperture, and wherein the first and second elastomeric membrane elements provide sufficient elasticity to prevent crimping of the catheter.
6. The clip of claim 4 , wherein the first and second elastomeric reinforcing elements form a reinforcing ring when the clip is in a closed position.
7. The clip of claim 6 , wherein the first and second elastomeric reinforcing elements each comprise a plurality of reinforcing ribs.
8. The clip of claim 4 , wherein the first and second elastomeric membrane elements comprise an elastomeric material.
9. The clip of claim 8 , wherein the elastomeric material comprises rubber, latex, or silicone.
10. The clip of claim 1 , wherein the first and second elastomeric membrane portions provide sufficient elasticity to prevent crimping of a catheter gripped within the second aperture.
11. The clip of claim 10 , wherein the frame member comprises a living hinge.
12. The clip of claim 10 , wherein the first frame member portion, hinge portion, and second frame member portion comprise a unitary structure.
13. The clip of claim 1 , wherein the frame member comprises plastic, polyethylene, or polypropylene.
14. The clip of claim 1 , wherein the frame member comprises a closure member adapted to selectably retain the clip in a closed position.
15. The clip of claim 14 , wherein the closure member comprises a pair of interlocking hook members.
16. The clip of claim 14 , wherein the closure member comprises a thumb tab configured to facilitate opening of the clip.
17. The clip of claim 1 , wherein the elastomeric inner gripping membrane is coupled to the frame member with adhesive.
18. The clip of claim 1 , wherein the elastomeric inner gripping member is coupled to the frame via a tongue and groove interface.
19. The clip of claim 1 , wherein the frame member comprises plastic, polyethylene, or polypropylene, and wherein the inner gripping member comprises rubber, latex, or silicone.
20. A method of using the clip of claim 1 , the method comprising:
inserting a catheter into the vasculature of a subject;
advancing the adjustable catheter within the vasculature past a tortuosity; and
securing the base of the clip to a substrate adjacent a portion of the catheter external to the body of the subject; and
closing the clip about the catheter with the catheter passing through the second aperture of the clip.
