Abstract: A valve assembly with a valve shaft shiftable within a valve well from an off position blocking fluid communication between ports in the valve well, and an on position allowing fluid communication between such ports. The valve shaft is in a stable position in either the off position or the on position such that force need not be applied to maintain the valve shaft in either the off position or the on position once the valve shaft has been moved to such position.

Abstract: Systems and methods for a medical valve are disclosed. For example, the medical valve may include a valve body including a body outlet aperture and a body inlet aperture, and an inner shaft including an inner shaft outlet aperture and an inner shaft inlet aperture, wherein the inner shaft is configured to rotate such that the medical valve transitions to an active state whereby the body inlet aperture and the inner shaft inlet aperture are substantially in alignment.

Abstract: An ostomy device includes an implant shaped in a ring and sized for placement in or adjacent to a hole in an abdominal wall, the implant including a surface for contacting a lumen. The implant includes a first part including the surface for contacting the lumen, the first part, when placed in or adjacent to the hole in the abdominal wall, extending in a direction orthogonal to the abdominal wall to support the lumen. The implant includes a region for attaching an ostomy bag.

Abstract: An ostomy device includes an implant formed of a flexible material and shaped so that the implant is capable of transitioning between a first shape and a second shape. The implant includes a tubular body sized and shaped for insertion within a lumen extending through a hole in an abdominal wall, a flared portion extending radially outward and away from the body when the implant is in the first shape, and a transition region between the body and the flared portion. The transition region and the flared portion are bendable so that transitioning the implant from the first shape into the second shape comprises inverting the flared portion so that a surface of the flared portion can be brought into contact with an outer surface of patient anatomy, whereupon the implant can be attached to the patient anatomy in the second shape.

Abstract: An ostomy bag device includes a bag with first and second chambers communicating via a first opening and a pressure sensitive interface. The bag includes a second opening interfacing with a stoma exit and receiving waste in the first chamber, a third opening expelling the waste from the first chamber, and a fourth opening releasing gas from the second chamber. The interface transitions from a first state in which the interface prevents a gas flow through the first opening from the first to second chambers and a second state in which the interface allows the flow. A first pressure differential in the first chamber relative to the second chamber causes the interface to assume the first state preventing the flow and a second pressure differential in the first chamber relative to the second chamber higher than the first differential causes the interface to assume the second state allowing the flow.
