Abstract: A biopsy needle for collecting a tissue specimen includes an outer cannula that is at least partially received within a handle housing and an inner tube received within the outer cannula and configured to receive a stylet. A snare coil is attached between the inner tube and the outer cannula and is configured to wind down when the inner tube rotates in a first direction relative to the outer cannula and uncoil when the inner tube rotates in a second direction relative to the outer cannula. The outer cannula is fixedly coupled to a needle holder that is coupled to and moves with a movable base that is axially movable within the handle housing. An inner driven structure (curvilinear part) is configured to selectively engage the movable base and travel therewith in a first stage of operation and in a second stage of operation in which the inner driven structure is disengaged from the movable base, the inner driven structure is driven along the movable base which is held in a stationary position.

Abstract: This invention is directed to a coupler which comprises an actuator housing and a plunger housing each formed with a passageway for transmitting fluid entering an indwelling catheter to a collection bag. As the housings are connected together, a plunger located in the passageway of the plunger housing is moved from a closed position to an open position by an actuator mounted in the actuator housing in such a way that a seal is continuously maintained in the plunger housing to prevent the escape of fluids from its passageway. A quick-release locking mechanism maintains the two housings in a locked position when the plunger is in the open position, and may be easily activated to permit separation of the housings from one another when it is desired to empty or replace the collection bag.

Abstract: A system is provided for collecting bodily fluids, and particularly urine from the bladder of a patient, comprising a catheter inserted into the bladder, a low pressure, cyclic magnetic valve coupled to the catheter, a collection bag, and, a quick-release coupler interposed between the magnetic valve and the collection bag.

Abstract: The invention provides an extension cable system for connecting electrodes to a medical device such as an External Pacing Generator. The system further provides a connector separator for maintaining electrode receiving connectors in a fixed relationship relative to each other to avoid contact between electrically exposed regions of the electrodes. The extension cable system comprises electrically conductive leads electrically connected to a plug adapted to an electrical socket of a medical device, dielectrically shrouded electrode receiving connector(s) that form an electrical connection with a filamentous electrode or electrically conductive wire, and a connector separator for gripping and maintaining the electrode receiving connectors in a predetermined and rigid relationship relative to each other. The electrode receiving connectors comprise outer shrouds that can be threadably rotated to operate wire receiving chucks to receive electrode wires.
