The connector unit includes a supply interface designed for connecting the connector unit to a power supply, a data interface designed for connecting the connector unit to a data processing unit, and a control interface designed for connecting the connector unit to an integrated interface of the control unit. A supply connection of the control unit to the power supply and a data connection of the control unit to the data processing unit can be established at the same time by means of the connector unit. The application furthermore relates to a control unit for controlling an implantable blood pump and to a control system for an implantable blood pump.

A regional oximetry sensor can have a sensor head configured to secure to skin of a user and a stem extending from the sensor head. The sensor head can include an emitter configured to transmit optical radiation into the skin and at least one detector configured to receive the optical radiation after attenuation by blood flow within the skin. The stem can be configured to transmit electrical signals from the sensor head to a cable. A plurality of notches can extend from a perimeter of the sensor head towards an interior thereof. The plurality of notches can form a plurality of independently flexible cutouts in the sensor head configured to allow for movement of at least a portion of the skin of the user underlying the sensor head when the regional oximetry sensor is in use.

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.

Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include a cylinder that engages the lead body. The length of contact of the cylinder to the lead body is at least 0.010″ long while average contact pressure is no greater than (10 pounds per inch)/(contact length). Adequate electrical isolation is achieved, even when a debris particle is present between the inner cylinder and the lead body while insertion force remains acceptable.

An inductive charging antenna for charging the power source of an active implantable medical device (AIMD) is described. The charging antenna is supported on the body fluid side of the feedthrough insulator, on the device side of the insulator or it is embedded inside the insulator. The charging antenna is connected to electronic circuits housed inside the medical device to charge the power source so that the device can deliver electrical stimulation to a patient and receive sensed biological signals from body tissue, among other functionalities. If the charging antenna is supported on the insulator body fluid side, it is made from a biocompatible material such as platinum. However, if the charging antenna is embedded inside the feedthrough insulator or is supported on the device side of the insulator, it can be made from a less expensive material that is not biocompatible, for example, copper.

A connector assembly 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 method of ensuring an electrical connector for a medical device is disinfected or sterilized is disclosed. The method comprises: receiving the medical connector in a blocked state, wherein a component of the medical connector comprises a shape-memory alloy (SMA); and heating the medical connector to a sufficient temperature to change a shape of the SMA to an unblocked state. A medical connector comprising the SMA material is also disclosed.

A bio-signal apparatus comprises a first connection part, a second connection part and a seal. The first connection part comprises a sheet, which carries a patch electrode structure and comprises electrodes for reception of a bio-signal from a body of a mammal and first electrical connectors, the first electrical connectors being electrically connected with the electrodes. The second connection part comprises counterpart electrical connectors, and the first electrical connectors and the counterpart electrical connectors being repeatedly attachable and releasable with each other for transferring the bio-signal therethrough to data processing. The seal seals an interface of the first connection part and the second connection part against dust and moisture, and the seal surrounds the first electrical connectors and the electrical counterpart electrical connectors in a continuous manner.

A feedthrough for an AIMD is described. The feedthrough includes an electrically conductive ferrule having a ferrule sidewall defining a ferrule opening. The ferrule sidewall has a height. At least one recessed pocket has a depth extending part-way through the height of the ferrule. An oxide-resistant pocket-pad is nested in the recessed pocket. An electrical connection material is supported on the pocket-pad for making an oxide-resistant electrical connection to the ferrule. An insulator is hermetically sealed to the ferrule in the ferrule opening. At least one active via hole extends through the insulator with an active conductive pathway residing in and hermetically sealed to the insulator in the active via hole.
