摘要： A system for performing minimally invasive procedures in a body lumen may include a flexible catheter having a plurality of lumens including a main lumen configured to receive an endoscope and at least one tool lumen; a first working instrument slidably disposed within a first tool lumen of the at least one tool lumen; a plurality of support elements disposed at a distal end of the catheter, the plurality of support elements being configured to shift between delivery and expanded configurations, wherein in the expanded configuration, the plurality of support elements forms an expanded cage to reshape the body lumen and form a working space; wherein at least one of the plurality of support elements is a tubular shaft having an opening proximate the working space; and a filament extending through the tubular shaft to a clip disposed outside the opening, the clip being manipulatable by the first working instrument.

摘要： Devices for palliating gastrointestinal strictures using rapid exchange type enteral stent placement catheters. The catheter may include an inner member and an outer member, with the two members being slidable with respect to one another. In various device embodiments, a ramp for directing a guidewire out from within the catheter is provided using portions of the outer member or a shaped mandrel. The inner member may take a number of forms, including a tubular distal portion, a skived or integrally attached elongate midsection, and a proximal portion. A mandrel can be used in a portion proximal of the guidewire ramp, with the mandrel taking one of several disclosed forms.

摘要： An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk.

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.
