Abstract: Provided herein is a convertible prosthetic running blade having an adjustable, shiftable heel that can be stowed when running and deployed when walking. The shifting can be performed manually and easily by the wearer without the use of tools. The prosthetic running blade generally comprises a foot body having a toe end and an opposing heel end, and a heel attachment adjacent the heel end, which is shiftable from a running position to a walking position. The foot body is generally in the form of an elongated running blade design, which may have similar shape and construction as traditional c-shape or j-shape running blades, although other shapes and constructions may also be used.

Abstract: A prosthetic ankle includes a pair of prosthetic members movably coupled together to allow movement of the pair of prosthetic members with respect to one another. A hydraulic actuator or damper including hydraulic fluid in a hydraulic chamber is coupled to one of the pair of prosthetic members. A hydraulic piston is movably disposed in the hydraulic chamber and coupled to another of the pair of prosthetic members. A hydraulic flow channel is fluidly coupled between opposite sides of the chamber to allow hydraulic fluid to move between the opposite sides of the chamber as the hydraulic piston moves therein. A voice coil valve is coupled to the hydraulic flow channel to vary resistance to flow of hydraulic fluid through the flow channel, and thus movement of the piston in the chamber, and thus influencing a rate of movement of the pair of prosthetic members with respect to one another.

Abstract: A vacuum pump may be used to attach a prosthetic and/or orthotic device to a residual limb. The vacuum pump may be in line below a socket of a residual limb. The socket may be a portion of the prosthesis that accepts the residual limb. The vacuum pump may generate a vacuum condition between the prosthesis and the residual limb. Generally, a vacuum condition may be generated between a socket and the residual limb. The residual limb may be covered with a sock, elastomeric liner, or sheath covering the limb. The vacuum condition may positively attach the prosthesis to the residual limb without the need for straps, retaining pins, or suction type vacuum which do not use a vacuum pump.

Abstract: A device, a kit and a method are presented for permanently augmenting the pump function of the left heart. The basis for the presented innovation is an augmentation of the physiologically up and down movement of the mitral valve during each heart cycle. By means of catheter technique, minimal surgery, or open-heart surgery implants are inserted into the left ventricle, the mitral valve annulus, the left atrium and adjacent tissue in order to augment the natural up and down movement of the mitral valve and thereby increasing the left ventricular diastolic filling and the piston effect of the closed mitral valve when moving towards the apex of said heart in systole and/or away from said apex in diastole.

Abstract: An implantable valve replacement system for a cardiovascular valve may include an adjustable stabilizing ring. The stabilizing ring may be composed of a body member that is transitionable from an elongate insertion geometry to an annular operable geometry. The stabilizing ring may further include a plurality of anchors deployable in the annular operable geometry to engage the annulus of the cardiovascular valve. The ring may be used in conjunction with an implantable valve frame. The valve frame may be located within the ring and the ring, in turn, may be stabilized through the anchors engaging the valve annulus. The valve replacement system may be applied by engaging the ring in its annular operable geometry with the valve annulus through the anchors. The valve frame may be inserted through the opening of the ring, thereby forming a stabilizing mechanical contact between the frame and the annulus.

When the prosthetic valve is in a compressed state and is housed by the capsule, each of the atrial arms extends, in a serpentine shape, along the capsule and away from the tubular portion. Other embodiments are also described.

Abstract: A prosthetic foot comprising an internal keel (1) and an encapsulation material (2). The keel (1) is made of two parts (3,4), namely an elastic ankle (3) and an elastic blade (4), to ensure a behaviour of the prosthesis as close as possible to the biomechanics of a sound human foot (plantar flexion, dorsiflexion, inversion, eversion). The materials and design used for the keel (1) allow storing and releasing strain energy at the right phases of the gait cycle. Elastomeric foams act as safety features in specific areas to prevent keel overloading. The keel (1) is preferably encapsulated into two types of foam to fill internal space and as cosmetic feature as it has a human foot shape.

Abstract: A method of facilitating switching of a quasi-passive elastic actuator of a tunable actuator joint module of a robotic system between an inelastic state and an elastic state comprising configuring a quasi-passive elastic actuator to be operable with a primary actuator of the tunable actuator joint module to selectively apply an augmented torque to assist the primary actuator in rotation of a joint of the tunable actuator joint module. The method further comprises configuring an elastic component of the quasi-passive actuator to comprise a first vane device and second vane device rotatable relative to each other within a housing, supporting a valve assembly about the axis of rotation of the joint through the first vane device, and configuring a shunt circuit to facilitate fluid flow between compression and expansion chambers through the valve assembly.

Abstract: In some embodiments, the present invention provides a reverse shoulder glenoid prosthesis which supports the attachment of multiple different types of modular attachments that can: 1) provide additional scapular fixation (ie external to the glenoid) in order to improve glenoid implant fixation in cases of severe bone loss/fracture, 2) provide joint line lateralization to improve tissue stability in cases of severe glenoid/scapula bone loss, 3) facilitate use and containment of glenoid bone graft in cases of severe glenoid/scapula bone loss—particularly in those cases in which the glenoid defect is uncontained/peripheral 4) achieve glenoid fixation while at the same time reconstructing the scapular bone in cases of scapula fractures, glenoid fractures, and/or acromial fractures, and 5) provide improved rTSA joint biomechanics, particularly posterior rotator cuff efficiency by changing the line of action of the infraspinatus and teres minor muscles to improve their muscle tension, and also increase each muscle'

Abstract: A covering layer for a transcatheter heart valve is in various embodiments configured to prevent or reduce damage to the native valve tissue around the site where the prosthetic valve is implanted. In some cases, prosthetic valves are manufactured with the covering layer attached. Other covering layers are stand-alone accessories that can be mounted onto pre-existing prosthetic valves by an end user. Covering layers that can be mounted by an end user are provided with various features that can facilitate easier attachment of the covering layer to the prosthetic valve, which further reduces the possibility of damage to the covering layer or to the valve. Another covering is provided with two layers in order to insulate and protect the native tissue surrounding the implant from damage due to friction or abrasion, and/or other movement driven wear.

Abstract: An adjustable spinal fusion intervertebral implant is provided that can comprise upper and lower body portions that can each have proximal and distal wedge surf aces disposed at proximal and distal ends thereof. An actuator shaft disposed intermediate the upper and lower body portions can be actuated to cause proximal and distal protrusions to converge towards each other and contact the respective ones of the proximal and distal wedge surfaces. Such contact can thereby transfer the longitudinal movement of the proximal and distal protrusions against the proximal and distal wedge surfaces to cause the separation of the upper and lower body portions, thereby expanding the intervertebral implant. The upper and lower body portions can have side portions that help facilitate linear translational movement of the upper body portion relative to the lower body portion.
