Abstract: A flow control and collection system includes a flow control device having a tubular member in which an inflatable balloon is positioned about the circumference of the interior side wall for closing the passageway to movement of matter and liquid when the balloon is expanded and allowing flow when the balloon is contracted against the side wall to which it is attached. The flow control device includes an adapter at the outer end of the tubular member having one or more interlocking features. A waste collection bag has a sealed body with at least one opening and a flow control device adapter at the opening having one or more counterpoising interlocking features to removably lock the adapters together and passes waste material and liquid through the flow control device into the waste collection bag.

The flow control device includes an adapter at the outer end of the tubular member having one or more interlocking features. A generally outwardly extending flange may be configured at the outer end of the tubular member. The flange may be configured with an inflatable membrane having an inflated position wherein at least a portion of the inflatable membrane extends generally outwardly from the flange.

Abstract: A urinary control device for sealing off at a neck and along the inside wall of a bladder to prevent leaking and dislodging of the device from within the bladder is disclosed. The device includes an inner tubular member. The device also includes an expandable sealing member. A deployable stiffening member is positioned within the expandable sealing member. The stiffening member expands within the expandable sealing member to erect and shape the expandable sealing member. The deployable stiffening member strengthens the expandable sealing member, retaining the device within the bladder and sealing off the bladder against leaking.

Abstract: A bone marrow biopsy needle provided with blades which cut and retain a biopsy core. In one embodiment, the cutting blades of the needle are hinged at the distal end of the needle and are mechanically coupled to an actuator at the proximal end of the needle. The needle is preferably formed with inner and outer walls to provide a space therebetween for the mechanical coupling. The cutting blades are retained in a dead space against the outer wall of the needle when the needle is open. In lieu of a hinged arrangement, the outer wall of the needle may be tapered at its distal end so that the blades are forced together when they are pushed forward. In another embodiment, the cutting blades are pre-curved inward, but are retained against the inner surface of the needle wall until pushed forward. In yet another embodiment, the distal ends of the cutting blades rest within a curved circumferential recess provided in the needle wall, and, when pushed forward, move together to cut and retain the biopsy core.
