Abstract: A removable liner used in conjunction with a socket for a prosthetic device, in which a vacuum is wicked across the entire area of a porous fabric of the liner, is disclosed. The liner preferably includes a shaped-layer made from one of either a silicone or a urethane and has an exterior surface, an interior surface and a passage therein which opens at each of the two surfaces and connects to a valve of the socket. The liner further includes a first porous fabric covering at least a portion of the exterior surface of the shaped-layer including the corresponding opening of the passage, and a second porous fabric covering at least a portion of the interior surface of the shaped-layer including the corresponding opening of the passage. A vacuum source coupled to the liner, via the valve on the socket, draws a vacuum which is wicked across the entire surface of the first and second porous fabrics which interface with the socket and the user's residual limb, respectively. The vacuum secures the socket to the liner and the liner to the residual limb of the user.

Abstract: A vacuum assisted suspension system is used to increase or maintain negative pressure or vacuum in a sealed socket cavity as a socket and prosthetic limb attachment mechanism. The system includes a vacuum pump having a housing that defines an enclosed space to receive a fluid. At least one wall of the housing and at least one movable wall define a fluid compartment. The system includes a compression transfer element connected to the at least one movable wall and connected to a prosthetic foot. The compression transfer element causes the at least one movable wall of the fluid compartment to move and increase the volume of the fluid compartment in response to a compressive force on the prosthetic foot to draw in fluid from the prosthetic socket. In the absence of a compressive force, the volume of the fluid compartment decreases thereby expelling fluid out of the fluid compartment.

Abstract: The various embodiments simplify the delivery of an occlusive implant to a hollow anatomical structure, such as a fallopian tube. For example, the delivery devices don't need to be retracted manually to deploy the implant. When the devices are activated, stored energy or a powered drive member induces movement of the various components. The operator need only position the distal ends of the devices at the treatment site and then commence deployment by, for example, flipping a switch or changing the position of an activation button. The present embodiments thus increase the efficacy of occlusion procedures by reducing the likelihood of operator error.

Abstract: A prosthetic limb socket assembly includes a bleeder valve configured to automatically adjust vacuum pressure within the prosthetic limb socket based upon a difference in ambient air pressure and vacuum pressure within the prosthetic limb socket. The bleeder valve includes: a housing having a first end, a second end, and channel extending therethrough providing fluid communication between the ambient and the interior of the prosthetic limb socket; and a valve disc disposed within the channel and biased into a substantially sealed engagement with a valve seat, wherein a certain pressure difference between the ambient and the interior of the prosthetic limb socket is operative to overcome the bias and unseat the valve disc from the valve seat.

Abstract: The sealing sheath is for use with a prosthetic socket and associated liner. The sealing sheath includes a textile tube for surrounding at least a portion of a liner that is configured to wear on a residual limb. An annular seal, e.g. an elastomeric or silicone seal, is positioned adjacent a proximal end of the textile tube and continuously extends from an inside of the textile tube configured to be adjacent the liner, through the textile tube to an outside thereof configured to be adjacent an inside of the prosthetic socket. The annular seal may include a first wing on an inside of the textile tube configured to be adjacent the liner, a second wing on an outside of the textile tube configured to be adjacent an inside of the prosthetic socket, and a base connecting lower ends of the first and second wings to define a v-shaped cross-section of the annular seal.

Abstract: A prosthetic sleeve and socket system, the sleeve including dual flaps or skirts concentrically arranged about the sleeve and configured to form a sealed chamber between the sleeve and socket when the sleeve is inserted into the socket. An air permeable material is interposed between one of the skirts and the sleeve to maintain a continuous interconnected air layer therebetween. An expulsion valve is provided to allow air contained within the sealed chamber to be forced out of the chamber ahead of the sleeve when it is inserted into the socket, and a powered vacuum pump maintains the vacuum thereafter, if needed. The system allows for a substantial reduction in size of known sockets and permits, in some instances, the disposal of bulky suspension straps currently in use to force the socket against a residual limb.
