An implantable vein frame is contemplated in which two ring members are rigidly joined in spaced axial alignment via one or more interconnecting members. One of the one or more interconnecting members defines a protruding region that acts upon the implant placed within the frame and/or the vein that the vein frame is placed within to define a sinus region. The implant is placed within and scaffolded by the vein frame, and the vein frame is subsequently inserted within a vein via a venotomy, or interposed between two vein segments via vein interposition graft. The vein frame acts to support the structural integrity of the implant, and to scaffold and anchor the implant in place with the vein.

Implantable splinting devices for supporting a passageway defect in a patient that is formed from one or more support structures including a polymer or a polymer and acellularized tissue matrix that define a structural component that substantially conforms to a defective passageway of the patient. The structural component also has a plurality of pores. The implantable splinting device is capable of being placed around a trachea, a bronchi, an esophagus and a blood vessel of a patient. The implantable splinting device may also be configured for placement between the trachea, and the esophagus of a patient.

A stent is provided that includes a body extending between a distal and a proximal end. The body is defined by a plurality of elongated members, with each elongated member extending between a distal end that is coterminous with the distal end of the body and a proximal end that is coterminous with the proximal end of the body. Each of the plurality of elongated members are arranged so as to define a lumen extending along the length of the respective plurality of elongated members, the lumen extending between the distal and proximal ends of the body so as to form a lumen length. Each of the plurality of elongated members are configured to permit drainage of a fluid from within the lumen to an environment external the stent along the entire lumen length.

A luminal stent includes a first tubular body and a second tubular body sleeved on the first tubular body, and at least one end of the second tubular body is sealingly connected to an outer surface of the first tubular body. In a radial support section of the luminal stent, the first tubular body includes at least one first radial support structure arranged in a circumferential direction thereof, and the second tubular body includes at least one second radial support structure arranged in a circumferential direction thereof and a coating film covering the second radial support structure. The second radial support structure has greater radial deformability than the first radial support structure. After implantation, the luminal stent can form a semi-closed gap between the first tubular body and the second tubular body or between the second tubular body and a lumen wall.

The present disclosure is directed to methods, compositions, devices and kits which pertain to the attachment of stent-containing medical devices to tissue.

The present disclosure is directed to methods, compositions, devices and kits which pertain to the attachment of stent-containing medical devices to tissue.

This disclosure concerns medical devices, such as catheters and implantable devices, having radially adjustable features. More particularly, the catheters and implantable devices can radially expand and contract to perform various functions within the body. Expansion and contraction can be performed by a radially adjustable structure mounted on the medical device. For example, a medical device can include an body configured for in vivo introduction, a strip attached to the body and rolled into a ring such that layers of the strip radially overlap each other, and at least one motor actuatable by electrical energy to move the radially overlapping layers of the strip relative to one another and change a diameter of the ring and the body.

An implant includes a shape-memory material having a transformation temperature. The implantable element is configured to be implanted, and to perform a first therapeutic function when the shape-memory material is in a first shape. An energy applicator is configured to change the shape-memory material from the first shape to a second shape by raising a temperature of the shape-memory material to the transformation temperature by radiating energy to the implant from outside the body. The implant is configured to perform a second therapeutic function while the shape-memory material is in the second shape, the second therapeutic function being qualitatively different from the first therapeutic function. Other embodiments are also described.
