Tunneled catheter with hemostasis mechanism
First Claim
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 on the proximal end;
a tunneling device affixed to a distal end of the catheter;
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; and
said inflation tube connecting an inflation source with said hemostasis component and a flow control valve regulates flow of a fluid from said inflation source to said hemostasis component.

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.
