摘要： The invention relates to a medical device and a method of using it. The device is a stent which can be percutaneously deliverable with (or on) an endovascular catheter or via other surgical or other techniques and then expanded. The stent is configured to have a central portion defined by “open” cells and at least two end portions, defined by “closed” cells, spaced apart and directly connected to the distal and proximal ends of the central portion of the stent. The stent may also optionally have a covering or a lattice with openings.

摘要： A stented valve including a stent structure including a generally tubular body portion having a first end, a second end, an interior area, a longitudinal axis, and a plurality of vertical wires extending generally parallel to the longitudinal axis around a periphery of the body portion, wherein the plurality of vertical wires includes multiple commissure wires and at least one structural wire positioned between adjacent commissure wires, and a plurality of V-shaped wire structures having a first end, a second end, and a peak between the first and second ends, wherein a first end of each V-shaped structure extends from a first vertical wire and a second end of each V-shaped structure extends from a second vertical wire that is adjacent to the first vertical wire, wherein each V-shaped structure is oriented so that its peak is facing in the same direction relative to the first and second ends of the body portion, and a valve structure including a plurality of leaflets attached to the stent structure within the tubular body portion.

摘要： A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.

摘要： A tubular prosthesis that includes a scaffolding formed by at least one scaffolding filament; a cover; and at least one controlled ingrowth feature constructed and arranged to abut an inner surface of a lumen wall when the prosthesis is implanted in the body lumen. The controlled ingrowth feature may extend inwards or outwards from the prosthesis outer surface. The controlled ingrowth feature may be formed by a scaffolding filament; by a separate filament; by the cover; and combinations thereof.

摘要： A stent for insertion into a vessel of a patient includes an inner tube comprising a positive Poisson's ratio (PPR) material and defining a lumen extending along a longitudinal axis of the stent; and an outer tube comprising a negative Poisson's ratio (NPR) foam material and disposed around an entirety of the inner tube, the outer tube extending along the longitudinal axis of the stent. The stent is configured to exhibit an auxetic behavior in response to a deformation of the stent. An outer surface of the second portion is configured to apply a pressure to an inner surface of the vessel when the stent is implanted into the vessel and the deformation is removed.

摘要： A constraining structure for use with a balloon catheter can include multiple longitudinal struts and multiple, sinusoidal shaped radial rings. The constraining structure can expand to form a pattern of channels including substantially square windows. The constraining structure can modify, restrict, and control a shape and/or size of the balloon when inflated. Inflating the balloon catheter within the constraining structure can provide nonuniform pressure on a vessel wall adjacent the balloon.

摘要： Prosthetic valves and methods of use of prosthetic valves may be provided. In one implementation, a prosthetic valve may include an annular outer frame, an inner frame, and a plurality of ventricular anchoring legs extending from the outer frame. The outer frame may be formed at least partially of struts intersecting at junctions. At least one ventricular anchoring leg may include a first curved leg portion on a first surface of the leg, and a second curved leg portion on a second, opposite surface of the leg. The outer frame may also include a strut extending between a downstream end of the outer frame and the junction from which the at least one ventricular anchoring leg extends.

摘要： Biodegradable magnesium alloy implantable medical devices are protected to delay onset of corrosion, and thus biodegradability, or to corrode more uniformly. The protection allows for extended effective use of the devices while maintaining biodegradability. Examples of protective coatings include conversion coatings that at least partially remove exposed second phases from a surface of the magnesium alloy and coatings that provide a barrier between water and the surface of the magnesium alloy.

摘要： Devices, systems, and methods for delivering targeted therapy to tissue at a treatment site with the use of a stent. The targeted therapy may include a functional and/or therapeutic agent separate from the stent, or a component of a functional and/or therapeutic agent separate from the stent and reactive with another component of a functional and/or therapeutic agent on the stent. The agent or component of an agent may be delivered with the stent, and/or before delivery of the stent, and/or after the stent has been delivered.

摘要： A radially expandable, tubular stent, includes a first section having a first crush resistance force and a second section have a second crush resistance force, wherein the first crush resistance force is less than the second crush resistance force. The first section is connected to the second section to form a tube, connection of the first and second sections extending in an axial direction of the tube.
