Abstract: A lead adapter for a patient treatment system comprises a housing having a plurality of inlets, each inlet being segregated from an immediately adjacent inlet by a housing intermediate wall. A plurality of electrical contact assemblies residing in the housing are electrically connected to a respective one of a plurality of electrical contact posts. Each contact post has an exposed terminal portion residing in one of the plurality of inlets. A header is movably secured to the housing to selectively open and close the housing. With the header in an open position, an implantable lead is movable into a longitudinally extending opening in the header. The header is then manipulatable into a closed position to move an electrical contact of the lead into contact with a respective one of the electrical contact assemblies electrically connected to a respective one of the electrical contact posts. That way, the electrical contacts of the implantable lead are in electrical continuity with an exposed terminal portion of a respective one of the electrical contact posts.

Abstract: An active medical device has a feedthrough with at least two terminal pins that are connected to electronic components in the device housing. A lead connector is connected to a strain-relief device for a lead. The lead connector supports at least two connector pins that are detachably connected to the device terminal pins to thereby connect the device electronic components to the lead electrodes. The device housing has a length extending along a longitudinal axis, and secondary axes of the terminal pins connected to the connector pins are aligned parallel to the longitudinal axis. The feedthrough also has spaced-apart distally extending arms with detents, and the lead connector has spaced-apart lateral recesses. With the detents of the feedthrough arms received in the lateral recesses of the lead connector, the medical device is detachably connected to the strain-relief device and the lead.

Abstract: A medical tray that is useful for containing an implantable medical device is a body cavity is described. The medical tray is particularly useful in a craniometry and comprises a ceramic insert joined to a metallic main tray. The main tray comprises a base plate extending to an upstanding main sidewall. An inlet extends inwardly through the main sidewall and into the base plate with the inlet having an inlet peripheral edge. The ceramic insert comprises a planar plate portion extending to an upstanding insert sidewall. The insert has an insert peripheral edge having an insert shape that is conformal with an inlet shape of the inlet peripheral edge. A metallization is supported on the insert peripheral edge and a braze joins the metallization supported on the insert peripheral edge to the inlet peripheral edge.

Abstract: 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.

Abstract: An active medical device has a feedthrough comprising a ferrule sealed to a ceramic insulator supporting a short terminal pin and a long terminal pin that are connected to electronic components in the device housing. A silicone insulator residing in the ferrule abutting the ceramic insulator has first and second openings that house first and second metallic housings nesting respective coil springs. The metallic housings connected to the respective short and long terminal pins are axially aligned in the silicon insulator. A lead connector connected to a strain-relief for a lead supports a co-axial lead pin having electrically isolated center and circumferential outer conductors. When the lead connector/strain-relief subassembly is connected to the feedthrough, the center and circumferential conductors of the lead pin are electrically connected to the coil springs nested in the first and second metallic housings connected to the short and long terminal pins of the feedthrough.

Abstract: An active medical device has a feedthrough with at least two terminal pins that are connected to electronic components in the device housing. A lead connector is connected to a strain-relief device for a lead. The lead connector supports at least two proximally-facing C-shaped inserts with an annular spring nested therein that are detachably connected to the device terminal pins to thereby connect the device electronic components to the lead electrodes. The device housing has a length extending along a longitudinal axis, and secondary axes of the terminal pins connected to the C-shaped inserts/annular springs are aligned parallel to the axis with imaginary extensions of the connector axes extending into the device housing.

Abstract: An active implantable medical device (AIMD) has an alumina housing supporting at least two electrodes. A printed circuit board (PCB) assembly resides inside the housing. Two sintered platinum-containing pathways extend through the housing thickness from the electrodes supported on the housing body fluid side surface to a housing device side surface. A device side end of each of the two platinum-containing pathways is in electrical continuity with an electrical contact supported on the PCB to energize the electrodes for providing stimulation therapy to a patient or for sensing biological signals from the patient.
