The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.

An intracranial stent includes a proximal end, a distal end, and a tubular sidewall extending there between and a patch covering at least a portion of the sidewall; wherein the patch is capable of diverting blood flow past the neck of an intracranial aneurysm. The patch may be made of a photon-activatable material or a tightly woven metal material with a density greater than a density of the sidewall itself.

An intravascular device for treating a cerebral aneurysm, the device comprising an externally controllable expandable member, the expandable member comprising a plurality of wires that define walls of the expandable member; wherein in a relaxed state of the expandable member the walls comprise at least a first wall portion in which openings defined between the wires are small enough to prevent coils positioned within the aneurysm from exiting the aneurysm, the first wall portion comprising an axial length at least as long as a neck of the aneurysm; and at least a second wall portion in which openings defined between the wires are large enough to allow blood flow through; the second wall portion axially aligned relative to the first wall portion. In some embodiments, openings of the first wall portion are small enough to reduce radial blood flow to and/or from the aneurysm.

Apparatus including a core is advanceable toward a patient's heart valve. The core tapers in a distal direction toward the smallest perimeter of the core. The apparatus includes a first ventricular arm, which is articulatable with respect to a first atrial arm at a first articulation site, and a second ventricular arm, which is articulatable with respect to a second atrial arm at a second articulation site. The articulation sites are adjacent to the smallest perimeter. The tapering of the core defines a minimum nonzero angle of the atrial arms with respect to a central longitudinal axis of the core. The first atrial arm and the first ventricular arm are arranged so as to clamp the first native leaflet. The second atrial arm and the second ventricular arm are arranged so as to clamp the second native leaflet. Other embodiments are also described.

An eye-implantable electrowetting lens 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 have different refractive indexes. 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. When the electrowetting lens is inserted into the eye, the lens chamber may contain only one of the first and second fluids. The other fluid can be added after insertion through a needle, a tube, or some other means. Having only one of the first and second fluids in the lens chamber during insertion of the lens can prevent fouling of internal surfaces due to folding or other manipulation of the lens during the insertion process.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

The present invention relates to a ring-shaped implant having shape memory for implantation in the cornea of the eye, wherein the implant spans an implant plane in a starting state, and wherein the implant is transferable by application of a compression force (F) in the implant plane (8) from a starting state into an intermediate state, in which the lateral dimensions of the implant, measured in the force direction, are smaller than in the starting state, wherein it is provided according to the invention that the alignment of an implant cross-section (1) in the intermediate state is pivoted at least in one pivotable longitudinal section of the implant by an angle (α) in relation to the starting state.

The present disclosure describes a cost-effective earplug device that delivers minimally distorted sound, offers sound protection, can fit most users, and can protect human hearing from dangerously-high acoustic levels without the cost or inconvenience of a custom earplug.

Implementations of a breast implant may include a shell including a posterior cephalic portion, a posterior caudal portion, an anterior cephalic portion, and an anterior caudal portion. Implementations of the breast implant may also include an anchor coupled within the shell and coupled directly and fixedly to the posterior caudal portion and the anterior caudal portion. The anchor may prevent rotation of the breast implant. The outer surface of the shell may be non-textured.

Implantable first atrial and ventricular arms are articulatable at a first articulation site to clamp a first heart valve leaflet. A first implantable elongate transitioning member is (a) connected at a fixed connection point at a portion of the first ventricular arm farthest from the first articulation site, (b) has a portion that faces an opposite surface of the first ventricular arm, and (c) is controllable to move the first ventricular arm. Implantable second atrial and ventricular arms are articulatable at a second articulation site to clamp a second leaflet. A second implantable elongate transitioning member is (a) connected at a fixed connection point at a portion of the second ventricular arm farthest from the second articulation site, (b) has a portion that faces an opposite surface of the second ventricular arm, and (c) is controllable to move the second ventricular arm. Other embodiments are also described.
