An illustrative stent may comprise an elongated tubular member having a longitudinal axis, the elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with intermediate rung portions extending circumferentially between radially adjacent twisted knit stitches. Each twisted knit stitch may be interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The elongated tubular member may be configured to move between a collapsed configuration and an expanded configuration, wherein in the collapsed configuration the series of linked stitches form longitudinal columns and in the expanded configuration the series of linked stitches extend helically around the elongated tubular member.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for reducing adverse optical effects from diffractive profiles of such a lens. Exemplary ophthalmic lenses can include an optic including a diffractive profile including a transition zone having an elevated surface roughness.

Hernia meshes are provided as well as methods of use thereof and methods of making.

The present disclosure relates to a three-dimensional, degradable medical implant for regeneration of soft tissue comprising a plurality of volume-building components and a mesh component which is substantially made of monofilament or multifilament fibers, wherein each volume-building component is attached to at least one point on a surface of the mesh component, and wherein the projected surface area of each volume-building component, when projected on the surface of the mesh component, corresponds to a maximum of one tenth of the surface area of the mesh component.

The present invention relates to a stent for transluminal implantation into hollow organs, in particular into blood vessels, ureters, esophagi, the colon, the duodenum, the airways or the biliary tract, comprising an at least substantially tubular body that extends along a longitudinal direction and that can be converted from a compressed state having a first cross-sectional diameter into an expanded state having an enlarged second cross-sectional diameter, wherein the stent comprises a stent body composed of a biostable material, characterized in that the stent body comprises a plurality of stent sections, preferably annular stent sections, that are in particular separate from one another, and the stent has a support structure that connects the stent sections to one another, wherein the support structure is formed from a bioresorbable material or comprises a bioresorbable material.

A filling apparatus for filling a lens device with a volume of optical liquid including a dispensing system, a venting system having a vacuum pump and a vacuum chamber, a measurement system, and a lens device holding system. The dispensing system includes a source of optical liquid, a positive displacement pump, and a filling needle having a lumen in fluid communication with the source of optical liquid. The filling needle is configured to penetrate an injection zone of the lens device for filling an internal chamber of the lens device. The measurement system is configured to measure a lens zone of the lens device. The lens device holding system includes a lens fixture for maintaining a position of the lens device relative to the filling needle and the measurement system. Related systems, devices, and methods are provided.

Prosthetic devices described herein include a body comprising a first end portion and a second end portion. The body defines a longitudinal lumen extending between the first and second end portions. In some embodiments, one or more anchor members are movably coupled to the body. Each anchor member can be selectively reconfigurable between a radially retracted position and a deployed position in which tip end portions of the one or more anchor members extend radially outward from an outer surface of the body. In some embodiments, a one-way valve is located within, and/or is otherwise in fluid communication with, the longitudinal lumen.

Methods for making surgical implants (or grafts) for the repair of bone defects, and more particularly, surgical implants that include demineralized bone fibers, are disclosed. Also disclosed are methods for increasing the wettability and ensuring uniform density of such implants. The surgical implants have a wettability time of less than 5 minutes and a residual moisture content of less than 6% by weight, and they remain cohesive and retain their shape upon complete rehydration.

A medical instrument with excellent operability is provided. The medical instrument includes stick-shaped extra-narrow metal members. The extra-narrow member has a hardened layer formed on the surface thereof without losing flexibility.

An implantable prosthesis includes a silicone shell having an apex, a base, a radius located between the apex and the base, and a dome extending between the apex and the radius. The silicone shell has an outer surface and an inner surface that surrounds an interior volume of the silicone shell. A silicone gel material is disposed within the interior volume of the silicone shell. A gelling enhancer layer containing a gelling enhancer covers the inner surface of the silicone shell. After the silicone gel material has been thermally cured, the silicone gel material that is located within a zone that is in the vicinity of the gelling enhancer layer has a higher level of cohesiveness than the silicone gel material that is located outside the zone. The gelling enhancer contains crosslinker and/or platinum catalyst, such as a Karstedt catalyst.
