An implantable medical device includes an electrically conductive first housing, a conductive feedthrough extending through the first housing, electronic circuitry positioned within the first housing, a device electrode, and a second housing. The electronic circuitry is electrically coupled to the first housing and the feedthrough, and senses electrical signals of a patient and/or delivers electrical stimulation therapy to the patient via the first housing and the feedthrough. The device electrode is configured to electrically connect with tissue and/or a fluid at a target site in the patient. A lead connector is configured to connect to a proximal end of an implantable medical lead. The lead connector includes a first connector contact electrically coupled to the feedthrough and a second connector contact electrically coupled to the first housing.

A pin extends proximally from the electrode base, wherein the pin is configured to be into contact with an electrical connector of an electronics assembly within the housing of the leadless biostimulator.

Implantable medical devices (IMDs) are described. The IMDs are configured to wirelessly receive power from an electromagnetic field provided by an external charger. The IMDs include a conductive case and a header that is typically non-conductive, and which houses a three dimensional antenna structure configured to couple with the external magnetic field. Currents induced in the antenna structure are used to provide power to the IMD. The three dimensional antenna structure may be configured as a cage structure comprising a first loop antenna proximate and parallel to the front of the header, a second loop antenna proximate and parallel to the back of the header, and a third loop antenna proximate and parallel to the top of the header. The three dimensional antenna structure allows the IMD to effectively receive power from different directions, for example, if the orientation of the IMD is flipped or otherwise shifted within the patient's body.

A medical implant includes a first component having a surface and a plurality of electrical contacts and a second component having a surface and a plurality of electrical contacts. Each contact of the first component contacts an assigned contact of the second component in an electrically conducting manner. A seal is disposed between the two surfaces for sealing the contacts. The seal and the two surfaces are formed of a thermoplastic material. The seal is fused to the two surfaces for sealing the contacts and the seal is meltable so as to separate the two components from one another. A method for producing a medical implant is also provided.

A hermetically sealed feedthrough assembly for an active implantable medical device having an oxide-resistant electrical attachment for connection to an EMI filter, an EMI filter circuit board, an AIMD circuit board, or AIMD electronics. The oxide-resistant electrical attachment, including an oxide-resistant sputter layer 165 is disposed on the device side surface of the hermetic seal ferrule over which an ECA stripe is provided. The ECA stripe may comprise one of a thermal-setting electrically conductive adhesive, an electrically conductive polymer, an electrically conductive epoxy, an electrically conductive silicone, an electrically conductive polyimide, or a thermal-setting electrically conductive polyimide, such as those manufactured by Ablestick Corporation. The oxide-free electrical attachment between the ECA stripe and the filter or AIMD circuits may comprise one of gold, platinum, palladium, silver, iridium, rhenium, rhodium, tantalum, tungsten, niobium, zirconium, vanadium, and combinations or alloys thereof.

A ceramic subassembly manufactured by a 3D-printing process is described. The ceramic subassembly comprises a ceramic substrate having a sidewall extending to spaced apart first and second end surfaces. At least one via extends through the substrate from the ceramic substrate first end surface to the ceramic substrate second end surface. In cross-section, the via has a square-shape with rounded corners.

In various examples, a connector for an implantable medical device is configured to accept a lead therein and electrically couple to a lead contact of the lead. The connector includes a connector housing, which includes a bore portion including a bore hole therethrough. The bore hole includes a bore hole axis, the bore hole being sized and shaped to accept the lead within the bore hole. An attachment portion is coupled to the bore portion. The attachment portion includes an attachment hole within the attachment portion sized and shaped to accept a feedthrough wire within the attachment hole. The attachment hole includes an attachment hole axis offset from and non-parallel to the bore hole axis.

A feedthrough assembly for an implantable medical device includes a housing, a solid insert, one or more conductive elements, a metal filler, and a non-corrosive sealant. The housing defines a central cavity through a height of the housing. The solid insert is disposed within the central cavity of the housing. The one or more conductive elements extend through one or more apertures defined within the solid insert and extend through the central cavity of the housing. The metal filler is disposed within a joint defined by an outer surface of the solid insert and an inner surface of the housing that defines the central cavity. The non-corrosive sealant coats a top surface of the metal filler to inhibit corrosion of the metal filler.
