A surgical instrument is disclosed. The surgical instrument includes a shaft, a sensing array and a fluid detection circuit. The sensing array is positioned within the shaft. The fluid detection circuit is electrically coupled to the sensing array, and is configured to determine when a fluid originating from an environment external to the shaft is present within the shaft.

Systems and methods are provided for water resistant connectors. A male connector includes a rib or a draft angle that creates a seal when engaged with a female connector. A male connector includes an overmold that includes or is made of a thermoplastic elastomer. Male or female connectors include molds that include or are made of a thermoplastic polymer, such as polypropylene. A female connector includes spring contacts that fit within individual pockets of the female connector.

Medical devices include fixation structures that include retained portions that provide medical lead fixation within the medical devices. Lead extensions include fixation structures that include retained portions that provide medical lead fixation within the lead extensions. A grip that a clinician may grasp and manipulate is engaged with a nose structure of a header block of the medical device or a connector block of a lead extension and manipulation of the grip causes compression of a deformable structure to ultimately create fixation of the lead or lead extension within the header block or the lead within the extension connector block. The deformable structure may be the retained portion of the fixation structure or alternatively may be separate from the fixation structure.

A surgical instrument is disclosed comprising an actuator and circuitry mounted on and/or embedded in the actuator.

A terminal tool includes a main body, an electrical connector body, and an electrical connector. The main body includes a distal clamping section and a shaft. The shaft includes a window and a first lumen extending through the shaft for receiving a terminal end of an implantable lead. The electrical connector body includes a second lumen and is independently rotatable with respect to the main body. The shaft at least partially extends through the second lumen. The electrical connector is coupled to the electrical connector body and extends at least partially through the window of the shaft.

A cable assembly, comprising a component, a cable, a rigid adhesive and a flexible adhesive. The cable may be coupled to the component. The rigid adhesive may be applied to cover the connection of the cable to the component. The flexible adhesive may be applied to cover the rigid adhesive. The component may comprise a ball grid array (BGA) and the cable may be coupled to the BGA. A hypodermic tubing may be applied over a portion of the rigid adhesive.

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.

An example mold assembly includes a first core, a second core, and a retaining cap. The first core defines an insert seat configured to receive a mold insert. The first core and the second core are configured to define a mold volume adjacent the mold insert. The retaining cap is disposed about a curved end portion defined by the second core, and defines a curved cap surface in contact with the curved end portion. The retaining cap is configured to secure the second core at a predetermined orientation relative to the first core within predetermined tolerances. An example technique includes positioning a mold insert in the mold assembly, disposing the retaining cap about the second core, securing the second core at a predetermined orientation relative to the first core within predetermined tolerances, and depositing mold material within the mold volume.

A hermetic feedthrough terminal pin connector for an active implantable medical device (AIMD) includes an electrical insulator hermetically sealed to an opening of an electrically conductive ferrule. A feedthrough terminal pin is hermetically sealed to and disposed through the insulator, the feedthrough terminal pin extending outwardly beyond the insulator on the inside of the casing of the AIMD. A circuit board is disposed on the inside of the casing of the AIMD. A terminal pin connector includes: an electrically conductive connector housing disposed on the circuit board, wherein the connector housing is electrically connected to at least one electrical circuit disposed on the circuit board; and at least one electrically conductive prong supported by the connector housing, the at least one prong contacting and compressed against the feedthrough terminal pin, the at least one prong making a removable electrical connection.

A feedthrough connector contains an electrically insulating body formed from glass. The body has a front side and a back side facing away from the front side. The body further has a circumferential lateral side extending from the front side to the back side of the body. The body has a plurality of through-openings, wherein each through-opening extends from the front side to the back side of the body. A plurality of electrical conductors is provided and, each conductor is arranged in one of the through-openings to hermetically seal the respective through-opening. The respective conductor contains a metallic material. A first end of the conductor is arranged at the front side and is connected to a first contact pad arranged on the front side, and an opposing second end is arranged at the back side and is connected to a second contact pad arranged on the back side. A method for producing the feedthrough connector includes to provide blind holes in the body with metallic material filled into the blind holes to define conductors.
