Abstract: Disclosed herein are electrically conductive and hermetic vias disposed within an insulator substrate of a feedthrough assembly and methods for making and using the same. Such aspects of the present invention consequently provide for the miniaturization of feedthrough assemblies inasmuch as the feedthrough components of the present invention are capable of supporting very small and hermetic conductively filled via holes in the absence of additional components, such as, for example, terminal pins, leadwires, and the like.

Abstract: A miniature electrochemical cell having a volume of less than 0.5 cc is described. The cell has a casing of first and second ceramic substrates that are hermetically secured to each other to provide an internal space housing an electrode assembly. First and second conductive pathways extend through the ceramic substrates. The pathways have respective inner surfaces that are conductively connected to the respective anode and cathode current collectors and respective outer surfaces that provide for connection to a load. An electrolyte in the internal space of the housing activates the electrode assembly.

Abstract: A new weld configuration is used to obtain a robust and consistent resistance weld between the tabs of an anode current collector and the casing of an electrochemical cell. This is done by adding a resistive transferable electrode tip between at least one of the welding electrodes, preferably the movable welding electrode, and the stacked parts that are being joined together. The purpose of the transferable electrode tip is to generate a sufficient amount of heat during the welding process so that the stacked parts are joined together without adding any product functionality. In one embodiment of the present invention, the transferrable electrode tip is a stainless-steel ball, the stacked anode current collector tabs are of nickel, and the cell casing is of stainless-steel.

Abstract: A surgical tool handle comprising a tool attachment coupling having locking piston subassembly is described. The attachment coupling is designed with a bayonet-type fitting having a series of coupling grooves constructed to accept surgical cutting tools having an attachment member of different cross-sectional geometries. More specifically, the attachment coupling comprises a coupling groove that accepts tool attachment members having both curved and rectangular cross-sectional geometries. In addition, a locking piston subassembly biases against the surgical tool attachment member received in the coupling groove to further stabilize the tool during a surgical procedure.

Abstract: A medical device includes telemetry circuitry configured to receive programming instructions. The medical device also includes stimulation circuitry configured to generate a plurality of electrical pulses in response to the programming instructions to provide an electrical stimulation therapy for a patient. The stimulation circuitry includes a voltage converter, a multiplexor, and a stimulation driver.

Abstract: A method of manufacturing a feedthrough dielectric body for an active implantable medical device includes the steps of forming a ceramic body in a green state, or, stacking discrete layers of ceramic in a green state upon one another and laminating together. The ceramic body has a first side opposite a second side. At least one via hole is formed straight through the ceramic body extending between the first and second sides. At least one via hole is filled with a conductive paste. The ceramic body and the conductive paste are then dried. The ceramic body and the conductive paste are isostatically pressed at above 1000 psi to remove voids and to form a closer interface for sintering. The ceramic body and the conductive paste are sintered together to form the feedthrough dielectric body. The feedthrough dielectric body is hermetically sealed to a ferrule.

Abstract: A cutting head for use with an intramedullary reamer is described. The reamer cutting head is of a unitary body construction that comprises a conically-shaped body having a bone cutting portion spaced from a barrel portion for attachment to a drive shaft. The bone cutting portion comprises a plurality of blades having a tissue cutting edge that outwardly extends from the cylindrical body. The plurality of blades is positioned about the cutting head in a spaced apart manner. The various plurality of blades are arranged at prescribed angular relationship that increases cutting efficiency and debris removal, thereby reducing reactive torque, axial loading, and head pressure during a surgical procedure.

Abstract: An electrochemical cell comprising a cathode and an anode residing within a casing, the anode being positioned distal of the cathode. The cathode having a cathode current collector having an angled configuration that encourages the cathode active material to move in an axial distal direction during cell discharge. The cathode current collector may be configured having at least one fold thereby dividing the current collector into at least two portions having an angle therebetween. The cathode current collector may comprise a wire having a helical configuration or the cathode current collector may comprise a post with a thread having a helical orientation about the post exterior. A preferred chemistry is a lithium/CFx activated with a nonaqueous electrolyte.

Abstract: A medical device includes a housing and an electrode arrangement coupled to the housing and configured to sense an electrical physiologic signal from a patient. The device also includes detection circuitry coupled to the electrode arrangement and configured to obtain a cardiac signal component and a non-cardiac signal component from the physiological signal. A processor is coupled to the detection circuitry. The processor is configured to detect patient activity using at least the non-cardiac signal component and discriminate between voluntary and involuntary activity of the patient based on a comparison of temporally aligned cardiac and non-cardiac signal components.

Abstract: A method for manufacturing a feedthrough dielectric body for an active implantable medical device includes the steps of first forming a ceramic reinforced metal composite (CRMC) paste by mixing platinum with a ceramic material to form a CRMC material, subjecting the CRMC material to a first sintering step to thereby form a sintered CRMC material, ball-milling or grinding the sintered CRMC material to form a powdered CRMC material; and then mixing the powdered CRMC material with a solvent to form the CRMC paste. The method further includes forming an alumina ceramic body in a green state, forming at least one via hole through the alumina ceramic body, filling the via hole with the CRMC paste, drying the ceramic body including the CRMC paste to form a first CRMC material filling the via hole, forming a second via hole through the first CRMC material, providing a metal core in the second via hole, and subjecting the ceramic body including the first CRMC material and the metal core to a second sintering step to thereby form the dielectric body. The dielectric body is then sealed in a ferrule opening to form a feedthrough.
