Abstract: A prosthesis for a residual limb includes an element for receiving a stump fitted on or established by a support part, a distal prosthetic part, and an absorbing system. The distal prosthetic part is assembled on the support part by a pivot link forming a joint to enable flexion or extension of the distal prosthetic part with respect to the element for receiving. The absorbing system absorbs the flexion or extension efforts and is connected to the distal prosthetic part and to one of a rod or a lever that is pivotally fitted on the distal prosthetic device. The rod is mounted to the lever and to the support part.

Abstract: An eye-implantable device including an electrowetting lens is provided that can be operated to control an overall optical power of an eye in which the device is implanted. A lens chamber of the electrowetting lens contains first and second fluids that are immiscible with each other and that differ with respect to refractive index. By applying a voltage to electrodes of the lens, the optical power of the lens can be controlled by affecting the geometry of the interface between the fluids. One or both of the fluids can have a melting point slightly below body temperature. Freezing such an oil or other fluid of the lens can prevent fouling of internal surfaces of the lens due to folding or other manipulation of the lens during implantation. Once implanted, the fluids are melted by body heat such that the optical power of the lens may be controlled.

A method may include receiving data from a sensor embedded in a femoral head component, the femoral head component configured to fit in an acetabular component, determining information about a magnetic field from the data, and outputting an indication of an orientation, coverage, or a force of the femoral head component relative to the acetabular component.

Abstract: Various intraocular pseudophakic contact lenses are disclosed. For example, an intraocular pseudophakic contact lens can include a first optical lens and multiple anchors. The first optical lens is configured to at least partially correct a residual refractive error in an eye. The anchors are configured to be inserted through an anterior surface of an intraocular lens into lens material forming a second optical lens of the intraocular lens in order to secure the intraocular pseudophakic contact lens to the intraocular lens. The anchors can be configured to couple the intraocular pseudophakic contact lens to different types of intraocular lenses, including intraocular lenses not specifically designed to be coupled to or receive the intraocular pseudophakic contact lens. The intraocular pseudophakic contact lens could also include at least one drug-eluting device located on the first optical lens and configured to deliver at least one medication.

Abstract: A patellar implant includes a body and at least one oblique anchoring pin. The body includes a bone-facing surface that is substantially planar and has a lateral end and a medial end. The body also includes an articulating surface opposite the bone-facing surface. The at least one oblique anchoring pin extends from the bone-facing surface at an acute angle toward the lateral end of the bone-facing surface. The at least one oblique anchoring pin includes a first end attached to the bone-facing surface and a second end spaced from the first end. A longitudinal axis extends from the first end to the second end. The longitudinal axis defines the acute angle with respect to the bone-facing surface. The at least one oblique anchoring pin extends into a surgically-prepared patella when the patellar implant is such that the surgically-prepared patella abuts the bone-facing surface.

Abstract: A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having anterior surface, a posterior surface and at least one diffractive structure including a plurality of zones. The at least one diffractive structure is for at least one of the anterior surface and the posterior surface. Each zone includes at least one echelette having a least one step height.

To compensate chromatic aberration of eye from distance to a range of vision, a greater than 2? phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by ?. Hence chromatic aberration of eye may be compensated to improve vision from distance to near.
