A method for producing a head part of an implantable medical device is described, with a head part housing, which has a recess in the form of a blind hole, along which at least one electrically conducting contact ring element, together with an electrically insulating, elastically deformable sealing ring, are joined together in a force fit in a coaxial arrangement and an axial serial sequence under an axial joining force. The method is characterized in that the generation of the joining force between the at least one contact ring element and the sealing ring is executed along the assembly tool by use of means of attachment fitted on both sides of the at least one contact ring element and the sealing ring along the assembly tool, of which at least one means of attachment is axially movably and detachably fixed in an axially secure manner to the assembly tool.

An electrical feedthrough (1) is provided for improving the thermal properties and the electromagnetic compatibility (EMC) and also for simplified production of a medical instrument (7), in which electrical feedthrough individual contact pins (4), which are guided through a glass body (2) in a housing (20) of the instrument (7), are electrically connected to one another by a pluggable plug element (5), preferably in the form of a sheet metal part. Here, the plug element (5) firstly provides high thermal and electrical conductivity and secondly provides a shielding area that effectively prevents the input coupling of electromagnetic radiation. Preferably, the plug element (5) is formed in such a way that it independently develops a holding force for securing itself to the contact pins (4).

A connector assembly for use in a medical device system is provided. The connector assembly includes a female connector including a jack and at least one female electrical contact disposed in the jack, where the at least one female electrical contact includes an outer ring and leaf springs extending both radially inward from the outer ring and longitudinally along the jack. The connector assembly also includes a male connector including a plug adapted to be inserted into the jack of the female connector, and at least one male electrical contact disposed on the plug, where the at least one male electrical contact is configured to electrically couple to a corresponding female electrical contact of the at least one female electrical contact by contacting the plurality of leaf springs of the corresponding female electrical contact when the plug of the male connector is inserted into the jack of the female connector.

A lead connector assembly includes a lead receptacle, a sleeve, and a handle for coupling to a medical lead. The lead receptacle has an inner surface and an opening configured to receive the lead. The sleeve is deflectable by the inner surface of the lead receptacle. The sleeve has a distal end portion defining a first outer diameter to engage the lead in a locked position and a second outer diameter greater than the first diameter in an unlocked position. The handle is coupled to the lead receptacle and a proximal end portion of the sleeve to move the sleeve axially in both directions along the longitudinal axis relative to the lead receptacle. The lead connector assembly retains the lead in the locked position. The lead receptacle is couplable to a medical device housing.

Connection systems and methods thereof facilitate establishing electrical connections through a barrier such as a drape without compromising a sterile field established by the barrier. A connection system can include two connectors. A first connector can include a first-connector housing defining a cavity, a slideable end piece coupled to a distal-end portion of the first-connector housing, and at least a first piercing element connected to a first electrical lead. The first piercing element can be configured to enter the cavity and pierce a barrier disposed in the cavity when the slideable end piece is advanced toward a proximal-end portion of the first-connector housing. A second connector can include at least a first receptacle within a second-connector housing connected to a second electrical lead. The first receptacle can be configured to form at least a first electrical connection with the first piercing element after the first piercing element pierces the barrier.

An electrode that includes an elongate lead body and a nerve cuff. The nerve cuff may include a biologically compatible, elastic, electrically insulative cuff body configured to be circumferentially disposed around a nerve, first and second relatively wide electrically conductive contacts carried by the cuff body that are spaced from one another in the length direction and that extend in the width direction to such an extent that they extend completely around the cuff body inner lumen when the cuff body is in the pre-set furled shape, and a plurality of relatively narrow electrically conductive contacts carried by the cuff body that are spaced from one another in the width direction and are located between the first and second relatively wide electrically conductive contacts.

A plug element for connecting a massage device to an energy source which includes a housing having two charging electrodes for connecting to an energy source, a control unit, a wireless data communications device, and a PCB antenna for transmitting and receiving radio signals of the wireless data communications device. The plug element also includes a cable emerging from the housing for connecting the plug element to the massage device. The plug element is provided at a first end of the cable and the opposing second end of the cable is configured for connecting to a massage device. The housing, the cable, and the connection between the housing and the cable are configured to be liquid-proof.

An implantable medical device includes a cover assembly and a feedthrough assembly that couples with the cover assembly. The cover assembly receives a connector end of a lead having lead contacts, and aligns the lead contacts with pockets or apertures of the cover assembly. The feedthrough assembly may include feedthrough contacts in the form of feedthrough pins at or above a surface of a feedthrough substrate, or conductive vias on the surface of the substrate. Electrical contacts configured as leaf spring contact assemblies, torsion spring contacts, or torsion spring contact assemblies are permanently attached to the feedthrough contacts. When the cover assembly and feedthrough assembly are coupled, contact tabs of the electrical contacts are positioned in the pockets or apertures of the cover assembly. Upon complete seating of the cover assembly and feedthrough assembly, the contact tabs are compressed into contact with the lead contacts.

A device for implant in a hole in cranium relative to a bone table includes a can having an electrical-contact pad. The can has a perimeter edge defining a boundary, and a recessed portion with an upper surface positioned to lie beneath the bone table when the can is placed in the hole. The device also include a cover assembly that couples to and decouples from the can at the electrical-contact pad. A strain relief system includes a lower strain relief and an upper strain relief. The lower strain relief defines channels that receive a portion of a lead and includes a curved portion that extends upward from the upper surface of the recessed portion to the bone table, and a linear portion that extends from the curved portion to an end beyond the perimeter edge. The upper strain relief couples to and decouples from the can and/or the lower strain relief.

Cable connection systems allow for an electrosurgical return electrode to be simultaneously connected to multiple ESUs. The cable connection systems can include individual return cables for simultaneous connection to each of the ESUs. The cable connection system can also include a junction that joins, connects, or associates the return cables in a manner that allows for the multiple ESU cables to be electrically connected to the return electrode at a single connection point on the return electrode.
