ABSTRACT:
A seal element for an opening in an implantable medical apparatus, which can be penetrated by a tool and which maintains a hermetic seal after removal of the tool, is in the form of a ring of resilient material, initially having a ring opening with the wall thickness of the ring being larger than the radius of the ring opening. The ring can be turned inside-out, whereby the ring opening is closed. The placement of the seal element in the opening in the implantable medical apparatus maintains the opening closed to form a seal, but permits insertion of a tool therethrough.
