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 tunneled catheter, comprising:

a catheter for long term hemodialysis having a distal end and a proximal end, wherein an anchoring cuff and a hemostasis component are disposed near on the proximal end;

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

the hemostasis component is an inflatable, double cylinder disposed proximally and distally of the anchoring cuff and both cylinders are inflatable by a same inflation tube.

2. The tunneled catheter of claim 1 wherein the double cylinder is inflatable and deflatable via administration of a fluid by an inflation source in fluid communication with the double cylinder in response to hemostatic needs of a patient, wherein the hemostatic need of the patient is blood visible at a point of catheter ingress into the patient.

3. The tunneled catheter of claim 2 wherein the inflation source is accessible to the patient.

4. The tunneled catheter of claim 2 wherein the fluid is selected from the group consisting of saline, purified water, and inert gases thereof.

5. The tunneled catheter of claim 1 wherein said hemostasis component includes a chemical compound having efficacy to promote hemostasis.

6. The tunneled catheter of claim 5 wherein the chemical compound is thrombin.

7. The tunneled catheter of claim 1 wherein the hemostasis component is formed from a flexible biocompatible material.
