A biodegradable device capable of producing a high radial force is described. Such a force will be created in devices made of relatively inelastic materials that are to be deployed to the vasculature or a body cavity in a patient. As the halves of the devices move together subject to a longitudinal force, at the point where they are in contact and unable to move closer together in the longitudinal direction, a radial force is created. The devices may have a tension element that assists in bringing the device halves together and which may partially and optionally remain within the body of the device.

A two-piece intraocular lens (IOL) with an anterior shape-changing optic is provided. The shape-changing interchangeable optic includes an elastic anterior face located anterior to the equator and comprising anterior arms releasably connected to actuating haptics of a base.

A percutaneous, transluminal, angioplasty system includes a non-foreshortening stent and a stent anchor to hold the stent in place until delivery. The stent comprises rings and fused rings comprising various motifs such as butterfly or pinched ellipsoid motifs. Stent anchors can release the stent after an outer sheath uncovers the stent or uncovers the stent and biased or bent fingers of the stent anchors.

The present disclosure relates generally to stents and methods for managing passage of material through a body lumen. In some embodiments, a medical stent may include a stent body defined by a hollow tubular elongate structure extending along a central axis, the stent body including a first portion and a second portion. The medical stent may further include a control region between the first and second portions, wherein in a first configuration the hollow tubular elongate structure of the control region is in a closed, twisted configuration, and wherein in a second configuration the hollow tubular elongate structure of the control region is in an open, expanded configuration.

In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.

A prosthesis for repairing a hernia defect includes a patch body, a hoisting frame releasably attachable to the patch body, and a tether attached to the hoisting frame with a free end extendable through the thickness of the patch body and accessible from the side of the patch body opposite to where the hoisting frame is releasably attached. The patch body and/or the hoisting frame includes a self-expanding support member. The hoisting frame includes a frame body with an outer frame component and a force translation component for directing pulling forces on the tether across the frame body. The outer frame component has a loop configuration to generally follow the patch periphery with overlapping end portions or a gap between free ends thereof. The force translation component is separable into multiple segments to facilitate withdrawal of the hoisting frame through an opening when released from the patch.

A mastopexy implant for maintaining the breast in an elevated and aesthetically pleasing position includes a lower pole support comprising end portions which may be affixed to the chest wall or to a previously installed upper suspension strut. The implant is loaded in an insertion device. The insertion device is inserted through a small incision and into a subcutaneous pocket created in an inferior half of the breast. The lower pole support may have various constructs and in one embodiment includes a unitary conformable mesh having a plurality of arm or band members which are attached across the breast parenchyma and to the chest wall.

A storable molded body is made of treated bacterial cellulose. The treated bacterial cellulose is dry and has a swelling capacity that is greater than untreated bacterial cellulose of the same type. The swelling capacity of the treated bacterial cellulose can be between about 103% and 154% greater than the non-treated bacterial cellulose. The bacterial cellulose can be from Gluconacetobacter xylinus. An implant includes or consists of the molded body of treated bacterial cellulose.

The present disclosure relates to valve replacement devices that are foldable for catheter-based deployment to the site of implantation, as well as systems for the delivery of valve prostheses, including prostheses having the special characteristics of the disclosed valve replacement devices. The devices include highly effective adhering mechanisms for secure and enduring precision implantation. The adhering mechanisms may employ a unique sealing mechanism that includes a cuff that expands slowly whereby the device is not secured in place until the completion of the implantation procedure. The implanted device, optionally together with the cuff, prevents perivalvular leaks and incorporate an appropriate leaflet system for reliable functioning in situ.

Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of the SI-joint and/or lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, SI-joint fusion or fixation; lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.
