摘要:
The implant (1) according to the invention is suitable for being anchored with the aid of mechanical vibration in an opening provided in bone tissue (21). The implant comprises an axis (11) and an axially extending implant opening as well as a material liquefiable by mechanical vibrations, which forms at least a part of the surface of the implant. A tool (3) used to anchor the implant has a proximal portion and a distal end portion (3.7), wherein the distal end portion has at least one cross-section which is larger than at least one cross-section of said implant opening and which distal end portion is able to be moved within the implant opening relative to the implant under the influence of a force and of the mechanical vibrations, whereby the implant is locally expanded under at least partial plastification of the implant, wherein the mechanical vibrations are able to be transmitted to a peripheral surface of the implant in the area of the expansion.

A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.

A prosthesis for insertion in an ear to reduce pain resulting from TMJ disorders. The ear insert has a predefined shape conforming to the shape of the ear canal when the jaw is in an open position. The ear insert supports the TMJ and associated secondary musculature to reduce strain in the TMJ area, including the muscles, ligaments, nerves, and the temporo-mandibular joint itself. The insert is hollow in the inside to permit hearing and is made of a rigid material which retains the shape of the ear canal. A scalloped indenture extends across a surface of the ear insert positioned behind the tragus.

A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by one or more of a mechanical interference fit, a polymer coating or melt, and/or by friction. The marker can take the form of a bead, rivet or snap-in marker, or a tube deformed when attached to the strut. The strut is made from a tube. The strut has a thickness of about 100 microns.

Implantable medical devices and method for making and using implantable medical devices are disclosed. An example implantable medical device may include a tubular body having a plurality of openings formed therein. A filter layer may be disposed along an outer surface of the tubular body. The filter layer may include a shape memory material. The filter layer may be capable of allowing fluids to pass therethrough and may be resistant to tissue ingrowth.

A stent graft (2) has a fenestration (10) surrounded by an inner edge, and the inner edge (7) further surrounded by an outer edge (9) of larger diameter. A shaped protrusion (4) of semi-rigid graft material spans the distance between the inner edge and the outer edge connecting the two edges. The shaped protrusion has a surface area larger than the plane of the tubular body between the edges and therefore has excess material which allows the inner edge and the fenestration to move within the circumference of the outer edge. The shaped protrusion may also form a semi-rigid dome.
摘要:
An incontinence treatment device includes a section of synthetic urethra and a closure device attached to the section of synthetic urethra. The section of synthetic urethra provides a flow diameter and is configured to be spliced into a natural urethra such that the flow diameter is aligned with a lumen of the natural urethra for passage of urine. The closure device is attached to the section of synthetic urethra and operable to coapt the flow diameter to allow a user to impede the passage of urine and be continent.

A moldable rigid ankle brace (10) is disclosed. The rigid stabilizing ankle brace includes a heat-moldable multi-layer housing (12) having an opening (121) for receiving a user's ankle, a footplate (14) attached to the housing, and a closure mechanism. The multi-layer housing includes a middle layer (24), which is substantially stiff at a temperature below about 54°C (130 °F) and moldable at temperatures between about 54°C and 135°C (130 °F and 275 °F). A method of stabilizing an ankle is also disclosed. The method may include providing a rigid stabilizing ankle brace, having a heat-moldable multi-layer housing having an opening for receiving a user's ankle, and a footplate removably attached to said housing, heating the ankle brace to between about 54°C and 135°C (130°F and 275°F), and applying said heated ankle brace to the ankle of a patient in need thereof.
摘要:
A length extensible implantable device includes a porous member and a longitudinal constraining member. The longitudinal constraining member can constrain at least a portion, up to the entire length of, the porous member in the longitudinal direction. The length of the longitudinally constrained portion can be expanded by applying force to the porous member. The porous member may be a porous tubular member.
