Abstract

A hemostasis component for an invasive medical device has an inflatable cylinder affixed to the medical device at a location aligned with an ingress point of a patient. An inflation source is in fluid communication with the inflatable cylinder and a flow control valve that is effective to regulate the flow of fluid from the inflation source to the inflatable cylinder is provided. The flexible cylinder is located on the proximal end of a tunneling catheter, where it exits the skin. A thin tube is provided to inflate the flexible cylinder. In the event of bleeding, the flexible cylinder is inflated for as long as is needed to achieve hemostasis, without having to place sutures. Inflation is a simple procedure that can be done by the patient, as opposed to having to place a suture, which must be performed by a physician or a physician'"'"'s delegate, under sterile conditions.

Claims

1. A hemostasis component for an invasive medical device, comprising:

an inflatable cylinder affixed to said medical device at a location aligned with an ingress point of a subject when said medical device is fully inserted;

an inflation source in fluid communication with said inflatable cylinder; and

a flow control valve effective to regulate the flow of fluid from said inflation source to said inflatable cylinder.

2. The hemostasis component of claim 1 wherein said inflatable cylinder is manufactured from silicone.

3. The hemostasis component of claim 2 wherein said fluid is saline.

4. The hemostasis component of claim 3 affixed to a proximal end of a tunneling catheter adjacent a first side of an anchor cuff

5. The hemostasis component of claim 4 wherein a second inflatable cylinder is affixed to said medical device adjacent an opposing second side of said anchor cuff

6. A tunneled catheter comprising:

a tunneling device affixed to a distal end of a catheter; and

a hemostasis component affixed to a proximal end of said catheter.

7. The tunneled catheter of claim 6 wherein said hemostasis component is an inflatable foam.

8. The tunneled catheter of claim 6 wherein said hemostasis component is a chemical compound having efficacy to promote hemostasis.

9. The tunneled catheter of claim 8 wherein said chemical compound is thrombin.

10. The tunneled catheter of claim 6 wherein said hemostasis component is an inflatable cylinder.

11. The tunneling catheter of claim 10 wherein an inflation source is in fluid communication with said hemostasis component and a flow control valve is effective to regulate the flow of a fluid from said inflation source to said hemostasis component.

12. The tunneling catheter of claim 11 wherein said fluid is selected from the group consisting of saline, purified water, and inert gases thereof

13. The tunneling catheter of claim 11 wherein said hemostasis component is formed from a flexible biocompatible material.

14. The tunneling catheter of claim 13 wherein said flexible biocompatible material is selected from the group consisting of silicone, polyethylene terephthalate and nylon.

15. The tunneling catheter of claim 11 being a hemodialysis catheter.
