摘要： An example medical stent for treating a body lumen is disclosed. The example stent includes an expandable scaffold having a first end region, a second end region and an outer surface. The stent further includes a first fixation member coupled to the expandable scaffold and a biodegradable material disposed along the first fixation member at a first tissue engagement region. Further, the biodegradable material is designed to degrade from a first configuration in which the biodegradable material shields the first fixation member from a target tissue site to a second configuration in which the first fixation member is engaged with the target tissue site.

摘要： A method for treating an intestine with an expandable scaffolding expanded within the intestine. After placing the expandable scaffolding at a target location, such as across a fistula, the first and second end portions of the expandable scaffolding are radially expanded such that the first and second end portions contact an inner surface of the intestine on opposing sides of the fistula, anchoring the first and second end portions to the intestine. Radially expanding the first and second end portions foreshortens the medial portion along the longitudinal axis such that the first and second end portions are drawn closer together along the longitudinal axis as the medial portion foreshortens to close the fistula.

摘要： A method for reducing mucus accumulation in an airway including disposing an implantable device within an airway, wherein the implantable device has a first end, a second end, and an inner surface defining a lumen extending from the first end to the second end; wherein at least a portion of the inner surface has a hydrophobic polymer coating thereon, wherein a polymer coating surface has dynamic water contact angles of 145 degrees or greater; and wherein the implantable device is constructed and arranged to maintain patency of the airway; wherein accumulation of mucus is reduced as compared to a similar implantable device without the hydrophobic portion of the inner surface. An implantable medical device having a superhydrophobic surface and a method of making an implantable medical device having a superhydrophobic surface are also provided. An implantable medical device having a micropatterned surface with enhanced adhesion to tissue, optionally in combination with other region(s) having a superhydrophobic surface and a method of making such a device. Methods and devices for prevention of bacterial adhesion to implanted medical devices.

摘要： A stent Includes a stent body formed by a strut. The stent body is cylindrically-shaped and extends in an axial direction. The stent body includes a plurality of helical portions and an annular portion. The strut is helically-shaped along the axial direction to form the plurality of helical portions and the strut is annularly-shaped in the circumferential direction to form the annular portion. Each of the plurality of helical portions has a distal end point and a proximal end point. The plurality of helical portions include a first helical portion and a second helical portion adjacent to the first helical portion in the axial direction. The annular portion is disposed between the first and second helical portions in the axial direction. At least one of the distal and proximal end points of the plurality of helical portions is directly connected to the annular portion.
