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.
