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: The above objects are achieved in accordance with the principles of the present invention in a female connector part for cooperation with an elongated male connector part, the female connector part being intended for use in a pacemaker housing and having a longitudinal bore adapted to receive the male connector part. An element carrying resilient tongues, disposed at a small inward angle, i.e. inward from the opening of the female connector part, relative to a plane orthogonal to the longitudinal axis of the bore. The tongues are movable between a first position at which the respective tips of the tongues can engage the male connector part in the bore, and a second position at which the tips of the tongues do not engage the male connector part in the bore. The female connector part also includes a sleeve which is movable between two positions respectively corresponding to the first and second positions of the tongues.

Abstract: An implantable cardiac stimulator has locking device for a pin-like conductor element of an electrode lead, the locking device having a helical coil which can assume a first, locking position, in which it grips the pin-like conductor element inserted into the coil to prevent longitudinal movement of pin-like conductor element, and a second, release position in which the pin-like conductor element is free to move in and out of the coil in relation to the coil's longitudinal axis. The first position is assumed when the coil is not influenced in its helix diameter increasing direction and the second position being assumed when the coil is influenced in its helix diameter increasing direction. The locking device also has a blocking component which only prevents the coil from rotating in the unwinding direction around its longitudinal axis in the locking device.

Abstract: A device for indicating that an electrode cable is correctly connected to a medical implant for emitting electrical pulses, the implant being equipped with a connection part for the electrode cable's proximal end, has a contact for making electrical connection with the proximal end of the electrode cable and an indicator, the contact electrically causing the indicator to emit at least one indication signal which is perceptible outside of the implant when the electrode cable is correctly attached to the implant.
