A medical stent may include a tubular support structure including a plurality of struts defining a plurality of cells disposed between the plurality of struts. A polymeric coating may be disposed over the tubular support structure such that a first portion of the plurality of cells are closed by the polymeric coating in a first region of the tubular support structure and a second portion of the plurality of cells in a second region of the tubular support structure remain open to fluid flow and/or tissue ingrowth therethrough. The struts in the first region of the tubular support structure and the struts in the second region of the tubular support structure may be at least partially covered by the polymeric coating.

A lymph conduction system implant includes a stent graft and a porous membrane. The stent graft has a non-porous tubular side wall. The non-porous tubular side wall has a proximal end and a distal end. The non-porous tubular side wall is configured to define a lumen having an inflow port at the proximal end and an outflow port at the distal end. All exposed surfaces of the stent graft are made of a first biocompatible material. The porous membrane is connected to the proximal end of the non-porous tubular side wall of the stent graft. The porous membrane is configured to span an entirety of a transverse area of the inflow port of the lumen of the stent graft. The porous membrane is made of a second biocompatible material.

An implant is provided for use in an ankle joint between reconditioned end surfaces established on a distal end of an upper tibia bone and an opposing lower talus bone. The implant comprises a substantially porous rigid component adapted to be anchored against the upper tibia reconditioned end surface and the lower talus reconditioned end surface. The component defining an opening therethrough. An intramedullary nail is configured to pass through the opening in the component when the nail is driven through the talus and into the tibia.

A corneal implant (10) includes a central portion (12) and a peripheral skirt (14) extending outwards from the central portion (12), and at least a portion of the peripheral skirt (14) includes a mesh (16).

In some aspects, the present disclosure pertains to self-expanding emboli-capturing centering devices for centering a medical instrument in a conduit within a patient. The centering devices comprise (a) an elongate shaft, (b) a self-expanding centering member having an open distal end and an inner surface forming a central lumen with a flared distal portion, the centering member being configured such that a fluid flowing in a distal-to-proximal direction that is received by the open distal end flows proximally along the flared distal portion of the central lumen before exiting the central lumen through one or more openings in a proximal portion of the centering member, and (c) a filter material configured to filter the fluid received by the open distal end of the centering member. Other aspects of the present disclosure pertain to systems and methods employing such centering devices.

A covered stent (100A), including a mesh-shaped support structure, and further including a first section (10A) and a second section (20A) connected to a proximal end and/or a distal end of the first section. The first section includes a plurality of first corrugated rings (11A), and a first covering film (12A) which covers surfaces of the first corrugated rings; the second section includes a plurality of second corrugated rings (21A), two adjacent second corrugated rings being fixedly connected to each other; a plurality of windows (201A) are formed between the plurality of second corrugated rings; and the plurality of first corrugated rings and the plurality of second corrugated rings form the support structure. The second section of the covered stent will not block an opening of a branch vessel (400), and thus it is not necessary to reduce the length of the covered stent in a main branch vessel, such that the covered stent has a sufficiently long anchoring area in the main branch vessel so as to ensure that the covered stent has sufficient anchoring force and thus prevent the displacement or endoleak of a distal end of the covered stent, thereby ensuring a good occluding effect.

The invention relates to a prosthetic valve (1) for regulating fluid flow between an upstream side (4) and a downstream side (5) and being operable between an open status and a closed status. The prosthetic valve comprises: —an orifice (2) arranged in a surrounding member (3) and extending between the upstream side (4) and the downstream side (5) wherein in the open status of the prosthetic valve (1) the fluid flow through the orifice is maximally enabled and wherein in the closed status of the prosthetic valve the fluid flow through the orifice in a restriction direction (21) from the downstream side (5) to the upstream side (4) is restricted; and—a leaflet (6) arranged in the orifice and being operable between an open status corresponding to the open status of the prosthetic valve and a closed status corresponding to the closed status of the prosthetic valve. The prosthetic valve further comprises regurgitation means (8, 15, 115, 22) arranged in the prosthetic valve for achieving regurgitation in the restriction direction and arranged for becoming ineffective after a period of deployment.

A device for attaching a soft tissue graft to bone includes a body with a smooth contoured first surface and a second surface opposite the first surface having a plurality of outwardly extending fixation members. The second surface is at least partially formed of a porous material adapted for bone ingrowth. A channel extends at least partially through the body in between the first and second surfaces for receiving a portion of the graft. The channel is at least partially formed of a porous material adapted for tissue ingrowth, bone ingrowth or a combination thereof.

A bone implant includes a main body in the form of a hollow body open on both sides in the axial direction. The main body includes a load-bearing material. An encasing body at least partially encases the main body on the outside and includes an in vivo degradable/in vivo resorbable material. Alternatively, the encasing body includes a multiplicity of shaped bodies protruding from the main body in the radial direction that include an in vivo degradable/in vivo resorbable material. A method for producing the bone implant includes an additive manufacturing process. The main body can be at least partially encased by the encasing body in the additive manufacturing process.

An orientable intravascular device having a “twelve o'clock” marker on a proximal and distal end for treating an aneurysm, including a packaging catheter with an identical fixed non-round shaped inner lumen, a pusher wire having an occlusion device releasably disposed on the distal end of said pusher wire, preloaded at a fixed circumferential orientation, with corresponding markers on the outside of said packaging catheter, a hub having an inner lumen that is shaped to marry with the outer lumen of the packaging catheter to deliver a delivery wire and occlusion stent in a predicted orientation, and maintaining such orientation as the wire and stent are advanced through said delivery catheter, and while said delivery catheter is withdrawn. Methods of using same are disclosed.
