Puncture closure
First Claim
1. Puncture closure to close a puncture of a blood vessel in body tissue of a patient which is under arterial pressure, the puncture including a puncture channel, said puncture closure comprising an outer layer of material and an inner layer structure with a pressure chamber (10, 30, 40) formed between said outer layer and said layer structure, which chamber is loadable with arterial pressure, said layer structure having an opening (13, 33, 43) for receiving a pressure medium which is the arterial blood pressure of a patient, said layer structure being capable of being fastened onto the body tissue of the patient in the vicinity of the puncture, the body tissue facing part of said pressure chamber (10, 30, 40) being extensible, said opening (13, 33, 43) for receiving the pressure medium being arranged within the body tissue for communicating with said pressure chamber (10, 30, 40), so that said opening (13, 33, 43) can be located above the puncture channel of the puncture and so that the blood flowing out of the puncture of the blood vessel itself can flow into said pressure chamber (10, 30, 40) for acting as the pressure medium.

Abstract
The puncture closure for closing a blood vessel with a puncture, in particular an artery, a vein short circuited with an artery, a shunt or a prosthesis, etc. has a pressure chamber in which an overpressure may be created, provided with an opening for receiving a pressure medium and fastenable to the body in the area of the puncture. The part of the pressure chamber that faces the body is extensible. In order to create a puncture closure that reliably closes the puncture of a blood vessel without too much blood loss, without forming significant hematomas nor completely collapsing the blood vessel, the opening for receiving the pressure medium is located above a piercing channel of the puncture hole and the blood that flows out of the blood vessel is used as a pressure medium.
