Abstract: A sealing plug having a self-sealing access slit is provided in a medical implant. An insert is inserted into the self-sealing access slit to preserve the slit during storage.

Abstract: An electrode lead for a medical implant, such as a pacemaker, has a proximal end for connection to the implant and a distal end opposite thereto having an electrode and fixation structure for holding the distal end in place relative to surrounding tissue. A distal end part at the distal end has a tape ring shape, in the form of a truncated cone, and the fixation structure forms a helical thread around the distal end part. The height of the thread is such that the crest of the thread is located within an imaginary, second truncated cone that is coaxial with the distal end part. The crest of the thread is located within an imaginary cylinder that is coaxial with the cylindrical lead body and which has the same diameter as the lead body, this imaginary cylinder intersecting the imaginary, second truncated cone.

Abstract: A metallic pulse generator housing has a tubular connector which receives a proximal lead end plug, the connector being located inside the housing and having a closed end within the housing and an open end welded or bonded to an opening in a wall of the housing. The connector is formed by a metallic barrel which is weldable or bondable to the metallic housing, the barrel being a structurally unitary tube member with a cavity containing electrical contacts for contacting contact surfaces on the lead end plug. At least one insulating substrate, on which the contacts are carried, is arranged in or on a region of a barrel wall which defines the cavity.

Abstract: An implantable heart stimulator has a connector for an electrode lead in the form of a self-contained tubular connector, which can be placed as a unit in one-half shell of a stimulator housing, together with a hybrid circuit and a power source. The other half shell of the stimulator housing can then simply be placed over these assembled components and joined thereto by welding, thereby considerably simplifying manufacture and assembly of the stimulator. When an even number of such self-contained connector tubes is employed, the two stimulator housing half shells can be identical.

Abstract: A device for affixing an electrode cable to an apparatus for emitting electrical pulses, such as a pacemaker or a defibrillator, cooperates with a connector part of the apparatus to which the affixing device for the proximal end of the electrode cable is attached. The electrode cable has a proximal end being provided with a center channel. In order to reduce the size of the connector part of the apparatus while still achieving good fixing of the electrode cable, affixing device includes an elongate body onto which the proximal end of the electrode cable can be mounted and an expander element for radially expanding at least a part of the elongate body, so the body can, when the cable end has been mounted, be affixed by pressure to the surrounding channel wall.
