A measurement device is disclosed that includes a first component having an outer surface having one or more flexible articular surfaces, and an inner surface having a first area having protrusions defining a polygon with a plurality of vertices. A load plate can be in contact with the first area. A printed circuit board can have a central section and a first lateral section. The first lateral section can have a sensor array having a plurality of sensors. Each sensor can be positioned in alignment with a vertex of the polygon and having a load pad in contact with a lower surface of the rigid load plate. A reference sensor can be spaced from the lower surface of the load plate.

A tunable implant, system, and method enables a tunable implant to be adjusted within a patient. The tunable implant includes a securing mechanism to secure the implant in the patient, a actuation portion that enables the implant to move and an adjustment portion that permits adjustment of the implant after the implant has been positioned within the patient. The method of adjusting the tunable implant includes analyzing the operation of the implant, determining if any adjustments are necessary and adjusting the implant to improve implant performance. The implant system includes both the tunable implant and a telemetric system that is operable to telemetrically receive data from the tunable implant where the data is used to determine if adjustment of the tunable implant is necessary. The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.

A selectively expanding spine cage has a minimized cross section in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

Disclosed are a self-switching transmission assembly, a balloon, and a prosthesis for use in a shoulder joint. The self-switching transmission assembly comprises: a communicating tube (11, 11′, 11″) comprising an input end (111, 111′, 111″) and an output end (112, 112′, 112″); an external connection tube (12, 12′, 12″), an end portion thereof being insertable into the communicating tube (11, 11′, 11″) from the input end (111, 111′, 111″) and removable from the communicating tube (11, 11′, 11″) from the input end (111, 111′, 111″); and a sealing tube (13, 13′, 13″), which can be placed in a tube body of the communicating tube (11, 11′, 11″) and moved axially relative to the tube body of the communicating tube (11, 11′, 11″). The sealing tube (13, 13′, 13″) comprises a connection end (131, 131′, 131″) and a sealing end (132, 132′, 132″), the connection end (131, 131′, 131″) being detachably connected to the end portion of the external connection tube (12, 12′, 12″) by means of a connection driving mechanism, and the sealing end (132, 132′, 132″) being provided with a pass-through region, wherein, when the pass-through region is exposed outside of the output end (112, 112′, 112″), the self-switching transmission assembly is in a pass-through state, and when the pass-through region is placed inside the tube body of the communicating tube (11, 11′, 11″), the self-switching transmission assembly is in a sealed and blocked state.

Provided is a kit for treating tissue of a subject. The kit includes a tool for creating a wedge opening within a bone tissue, and an implant. In some examples, the kit also includes an introducer configured to deliver the implant into the wedge opening.

A device for controlling urinary flow comprises a fluid inlet and a fluid outlet. The device comprises a valve movable between an open position in which fluid can flow from the fluid inlet to the fluid outlet and a closed position in which fluid flow is blocked between the fluid inlet and the fluid outlet, and an actuator operable to move the valve between the open position and the closed position. The actuator is positioned on a first side of the fluid inletand the fluid outlet is positioned on a second, opposite side of the fluid inlet.

A fixation device for engaging heart valve leaflets includes a center member with a first end, an opposite second end, and a length extending therebetween, first and second arms each having a first free end and an opposite second end, the second end of each arm extending from the second end of the center member, the first and second arms biased in a first position adjacent the center member and moveable to a second position spaced apart from the center member, and an actuator configured to move the first and second arms from the first position to the second position.

An accommodative intraocular lens includes an optic body having an optical power changing structure. There are two supporting structures disposed opposite one another about the optic body, each supporting structure configured to be connected at a distal end to a ciliary body after implantation in an eye of a patient and connected at a proximal end to the optic body. The two supporting structures are a zeroing supporting structure and an actuating supporting structure. The zeroing supporting structure is configured to not change the optical power of the optic body in an installation mode and an operation mode of the accommodative intraocular lens. An actuating supporting structure is configured to not change the optical power of the optic body in the installation mode but is configured to change the optical power of the optic body in the operation mode of the accommodative intraocular lens.
