摘要:
Detection apparatus can include a positioning device with a wall including a substantially conical inner surface and a detection device configured to send and receive signals and move along the conical inner surface. Detection apparatus are also provided that comprise a positioning device and an end portion with an image port, a light device, and a detection device configured to send and receive signals. Ultrasonic transducer devices are also provided with a transducer material layer, a contact plating layer including a convex portion with an array of transducer elements, an acoustic matching layer, and a top plating layer.

An electrochemical analysis system includes a chamber (34) that defines a fluid receiving reservoir therein. A working electrode (40), a reference electrode (42), and a counter electrode (44) is mounted to the chamber. An electrochemical analysis circuit (38) 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 (60) which is surrounded by a compressible polymeric sleeve (64) and a metal sleeve (66). One end of the metal sleeve is swaged (68) 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 (70) includes a bore (72) in the conductive rod in which the glassy carbon rod is slidably received and a compressed spring (74) in the bore.
摘要:
A contact assembly for a medical device and, more specifically, to a header contact assembly for achieving electrical contact with an in-line IPG lead utilizing a contact structure such as a “toroidal spring in groove” device.
摘要:
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.
摘要:
A connector assembly for a medical device for connecting the medical device to a relatively large plurality of electrodes that can support, in some cases, 24 or more stimulation channels for stimulating one or more stimulation regions of a patient. Also the medical device and the stimulation system and the stimulation therapy utilizing the connector assembly.

摘要:
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.

摘要:
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.
