A connector assembly, and its method of assembly, for use in a medical device for connecting an IPG to a connector assembly for connecting the IPG to a relatively large plurality of electrodes that can support 24 or more stimulation channels for stimulating one or more stimulation regions of a patient. Also the IPG and the stimulation system and the stimulation therapy utilizing the connector assembly.

Feed-through connector assembly for implantable pulse generator and method of use

A titanium alloy metal sheet is provided and heated to a superplastic forming temperature. A die has a plurality of housing forming areas each corresponding to one of the medical device housing portions. The heated titanium alloy metal sheet is forced onto the die and over each one of the plurality of housing forming areas, thereby superplastically forming a workpiece comprising a plurality of integrally formed implantable medical device housing portions.

Superplastic forming for titanium implant enclosures

A method of assembling a contact assembly for installation in a medical device, and more specifically, a header contact assembly for installation in an implantable medical device for achieving electrical contact with an in-line IPG lead for implanted electrodes, the assembly utilizing a contact structure such as a 'toroidal spring in groove' device.

Contact assembly for implantable pulse generator and method of use

A connector is described herein that includes a plurality of layers patterned in two dimensions and joined in a stack with a bore there through. At least a subset of the plurality of layers are contact layers that include deflectable members (e.g., springs) that deflect in plane or out of plane upon insertion of a lead into the bore through the connector. The deflectable members form redundant electrical connections with the lead when the lead is inserted into the bore. For example, the connector can be incorporated into an implantable medical device (e.g., IPG). Moreover, methods of manufacturing a connector are set forth herein.

Minimally invasive introducers and methods that can be used for rotationally securing devices within the human body. Introducers can include a distal element for releasably engaging a lead head controllable from a proximal control located outside of the body. An inner stem can extend between a proximal portion and a distal portion, and be pivotally and rotatably coupled to the distal lead engagement mechanism. An outer tube can be rotatably disposed over the inner stem and be flexibly coupled over the pivot to rotationally drive the distal element. A helical epicardial-myocardial lead electrode can be secured and oriented straight ahead and introduced through a port or small incision with the introducer in a straight configuration. The introducer can then be bent and rotated to screw the helical electrode into the heart.

An adjustable support apparatus for, e.g., supporting an instrument. The adjustable support apparatus may include a supporting member, an adjustable member engaging with the supporting member, a fastening member engaged with the adjustable member and an elongated member engaged with the adjustable member and adapted to interact with an instrument.

Adjustable support apparatus

An articulated arm for holding surgical instruments, having elongated arm members; rotational joints connecting the arm members end to end, such that members are pivotable about the joints and at least one of the joints is selectively lockable by fluid pressure; and a plurality of tubes communicating fluid pressure between two adjacent joints. When two adjacent members are pivoted relative to one another, the tubes connecting a particular pair of joints remains substantially stationary with respect to the arm member connecting that pair of joints.

Articulated arm for holding surgical instruments

An electrochemical analysis system includes a chamber ( ) that defines a fluid receiving reservoir therein. A working electrode ( ), a reference electrode ( ), and a counter electrode ( ) is mounted to the chamber. An electrochemical analysis circuit ( ) applies appropriate voltages to the electrodes and reads appropriate currents from the electrodes to provide an indication of the peroxyacetic acid concentration in a sample. The working electrode includes a glassy carbon rod ( ) which is surrounded by a compressible polymeric sleeve ( ) and a metal sleeve ( ). One end of the metal sleeve is swaged ( ) to form a fluid tight compression seal with the insulating sleeve and the glassy carbon rod. An electrically conductive thermal extension joint between the glassy carbon rod and an electrically conductive rod ( ) includes a bore ( ) in the conductive rod in which the glassy carbon rod is slidably received and a compressed spring ( ) in the bore.

Durable carbon electrode

A fluid delivery system ( ) for an automated processor (A) delivers washing, microbial decontaminant, and rinse fluids to spray nozzles ( ) in a chamber ( ) for sequentially spraying the fluids over a lumened device (B), such as an endoscope. The fluid delivery system also delivers the fluids to connection ports ( ) which connect with internal passages ( ) of the device for delivering the fluids thereto. Leaking connectors ( ) connect the automated processor connection ports with inlet ports ( ) of the device and allow a portion of the washing, decontaminant, and rinsing solutions to leak from each inlet port. A computer control system ( ) controls cleaning, decontamination, rinsing, and drying stages of a cycle, which are all carried out within the chamber, obviating the need for human contact with the device during processing. A door locking and latching mechanism ( ) ensures that the door remains locked during the washing, decontamination, and rinse cycle to avoid accidental injury to an operator from strong chemicals used in the system.

A fluid delivery system ( ) for an automated processor (A) includes spray nozzles ( ) for sequentially spraying washing, microbial decontaminant and rinsing solutions over a lumened device (B), such as an endoscope. The fluid delivery system also includes connection ports ( ) for connecting with internal passages ( ) of the device to deliver the washing and microbial decontaminant solutions thereto. A removable rack ( ), specially configured for the particular device, positions the device within a chamber ( ). The spray nozzles are located on rear and side walls ( ) and on a door ( ) of the chamber, such that the device is impinged with spray from all directions. Sets ( ) of the spray nozzles are pulsed in sequence so that the spray jets ( ) do not cancel each other out. Leaking connectors ( ) connect the automated processor connection ports with inlet ports ( ) of the device and allow a portion of the cleaning, decontaminant, and rinsing solutions to leak from each inlet port. A computer control system ( ) controls cleaning, decontamination, rinsing, and drying stages of a cycle, which are all carried out within the chamber, obviating the need for human contact with the device during processing.
