An implantable device for improving the pump function of the heart of a human patient by applying an external force on a first position of the heart muscle following the heart's contractions. The implantable device comprising a first pump device adapted to assist the pump function of the heart. The pump device comprises a first reservoir having a first volume and adapted to varying said first volume, a second reservoir having a second volume and adapted to varying said second volume, a fluid connection adapted to fluidly connect said first reservoir with said second reservoir, such that fluid can flow between said first reservoir and said second reservoir. The reservoir, said second reservoir and said fluid connection form a fully implantable pump device adapted to maintain a fluid in a closed system, when in operation and wherein said fully implantable pump device is adapted to transfer force by transferring fluid from said first reservoir to said second reservoir to directly or indirectly apply an external force on the first position of the heart muscle, following the heart's contractions, for improving the pump function of the heart, when said device is implanted. The implantable device further comprises a sensor sensing muscle contractions of the heart.

A vented chest wound seal for a penetrating chest wound includes a flexible sheet including a top surface and a bottom surface, an adhesive hydrogel layer covering a portion of the bottom surface of the flexible sheet, and a plurality of vent channels. The adhesive hydrogel layer includes an inner perimeter and an outer perimeter, and the outer perimeter forms a continuous perimeter of hydrogel along a bottom surface of the flexible sheet. A plurality of vent channels, each including a first opening to a space inside of the inner perimeter, extend radially outward to an outer terminal end vent to the top surface of the flexible sheet. The outer terminal end is spaced apart from the outer perimeter of the adhesive hydrogel layer towards the central portion of the chamber.

An integrated chest evacuation tube that is specifically configured to function as a closed tube when inserted and retained inside of a chest cavity to provide enhanced benefits over the state of the art. The integrated chest evacuation tube generally includes a fluid impermeable membrane fixedly attached to a single flexible hollow tube. The fluid impermeable membrane is interposed between an inlet port and an outlet port or optionally at said outlet port of a chest tube. The membrane is configured to seal the tube's passageway from any transfer of the fluid. The impermeable membrane is adapted to be ruptured by a force other than pressure from said fluid.

An integrated chest evacuation tube that is specifically configured for being a closed system when inserted and retained inside of a chest cavity provides enhanced benefits over the state of the art. The integrated chest evacuation tube generally includes a valve that is made up of a hollow elastomeric housing having a collar at an output end of the housing which provides an aperture into the housing, a valve input end at an input end of the housing, and an elongated slit at the valve input end. The slit is configured to close together in a spring-like manner when in a closed position. The valve is integrated and at least partially inside of a chest evacuation tube that has a tube inlet port and a tube outlet port. The tube inlet port is adapted to drain fluid and/or air from a human chest cavity. With the collar fixedly attached to the chest evacuation tube at essentially the tube outlet port, the elongated slit is adapted to be opened by a hollow tube when the hollow tube is forcibly pushed through the slit from a direction of the collar.

A chest wound seal for treating traumatic pneumothorax following a penetrating chest wound. The chest wound seal comprises a wound pad with an absorbent bottom surface and a nonporous top surface embedded with unidirectional valves that allow evacuation of air and fluid from the pleural cavity but prevents re-entry of air into the thorax. A central vacuum column mounted over at least one unidirectional valve. The chest wound seal further comprises a plurality of wound pad segments radiating from the central vacuum column, wherein each segment comprises at least one manual valve configured to create a separate sealed area against the skin surface to suit body types with different size and morphological features. The central vacuum column is adapted to be connected to a vacuum pump which enables evacuation of harmful air and fluid from the pleural cavity thereby reducing the shock induced by hypoxia and increasing patient survivability.
