Abstract: Expandable scaffolds or stents include circumferential elements having a corrugated pattern, which can include a plurality of linear or nonlinear segments. The corrugated pattern distributes stress more uniformly along the circumferential elements, improves radial strength of the scaffolds, reduces acute recoil after deployment, and reduces creep. The scaffolds can be made from a bioabsorbable material.

The device has a continuously knit elasticized fabric layer including a first set of yarns located about a circumference of the device through the first and second regions. The fabric layer has different knit structures in the first and second regions to obtain different elasticity while sharing the first set of yarns so that the first region has a first elasticity, and the second region has a second elasticity greater than the elasticity of the first region. An elastomeric layer secures an interior surface of the fabric layer.

A stem projects from the center of the internal fixation surface. The internal fixation surface comprises a top surface, surrounding and substantially orthogonal to a long axis of the stem, a chamfer surface extending downwardly and outwardly from the top surface and a side surface extending substantially parallel to the long axis of the stem. At least one projection is arranged on the internal fixation surface to provide a predetermined gap between the top surface and/or chamfer surface and a resected head onto which the implant is to be fitted. Furthermore, the side surface constitutes or comprises a cement containment feature configured to restrict or eliminate outflow of cement from the predetermined gap.

Abstract: A percutaneous heart valve for deployment within a body cavity is described. The percutaneous heart valve includes an expandable frame having a plurality of cells adapted for allowing the frame to expand and collapse. A one-way valve is positioned within the expandable frame. The frame includes a proximal anchoring portion and a distal anchoring portion. The distal anchoring portion includes a plurality of distal anchors, each distal anchor having at least a portion positioned radially outwardly from the frame and extending in a direction that is substantially parallel with a longitudinal axis. The distal anchors preferably bend radially outwardly before bending to extend toward the proximal anchoring portion. Radial expansion of the frame causes the proximal and distal anchoring portions to move closer together for capturing body tissue therebetween, thereby anchoring the percutaneous heart valve to the body tissue.

Abstract: A programmable prosthetic foot includes a heel member simulating a heel portion of a human foot. The heel member has an elongated heel member shaft extending in a vertical direction. The foot also includes a forefoot member simulating a forefoot portion of a human foot. The forefoot member has an elongated forefoot member shaft extending in the vertical direction. A sensor on the foot detects compressive force on the heel member shaft and/or forefoot member shaft during a step.

Abstract: A deformable intraocular has a haptic that supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may include a cap on one or both surfaces of the lens. The lens may include a force transfer member-that couples forces from the haptic to the cap, so that a radial force on the haptic changes the curvature of the cap. The cap may be made of the haptic material, which is stiffer than the optic material, and can influence the deformation of the lens during accommodation. A cap on the anterior surface may produce an axial movement of the lens in an anterior direction during accommodation. The cap may also protect the surfaces of the optic during handling and installation.

Abstract: A heart valve includes a valve body made of a flexible material such as pericardium. The valve body is made of two layers of material, an outer layer, and an inner layer that defines a plurality of leaflets. The leaflets of the inner layer are attached to the outer layer. In some embodiments the valve body is made by cutting a single piece of flat source tissue, folding the cut tissue and forming it into a tubular pattern having the inner and outer layers. The multi-layer valve body can be mounted on a stent for delivery within a patient's heart.

Abstract: A prosthetic joint is secured to the bones forming the original joint by utilizing strictly mechanical fasteners, for example, a threaded rod engaging a tapped intramedullary canal. Cross locking members may be provided. The need for bone cement is avoided. The prosthetic joint may be used to replace one end of one bone forming the joint, utilizing the naturally occurring end of the other bone. Alternatively, both bone ends may be replaced with prosthetic joint portions. The decision to replace one or both bone ends may be made mid-surgery. The prosthetic joint portions are secured together utilizing ligament reconstruction members made from portions of the patient's tendons or allograft tendons. A bearing forming the interface between the two joint portions is designed to wear in order to protect the remaining components from wear, and to be easily replaced in relatively simple future surgeries.

A plurality of struts are connected to the distal portion and distributed circumferentially about the axis. The struts at least in part define a receiving volume adapted to receive a residual limb and are movable between an expanded configuration in which at least some of the struts are moved radially outward relative to the axis to loosen the fit of the adjustable system, and a closed configuration in which at least some of the struts are moved radially inward relative to the expanded configuration to tighten the fit of the adjustable socket system. A tightening system is operatively connected to the struts and arranged to tighten and loosen the fit of the adjustable socket system on one or more areas of the residual limb.
