The present disclosure pertains to medical devices that comprise a stent body having two ends, a central region therebetween, and comprising structural elements extending around the stent body and a covering material disposed over the stent body, the covering material covering only a portion of the stent body, in which the covering material is provided with a plurality of openings that provide areas where the stent body is not covered by the covering material. The present disclosure further pertains to medical apparatuses that comprise such medical devices and methods of treatment using such medical devices.

A kit is provided comprising a stent, an introducer and a bender. The stent is constructed for insertion into a Eustachian tube of a human. The stent includes a member having a preinsertion form that includes opposing exterior surfaces, means for immobilizing the stent within the Eustachian tube, and means for providing fluid communication between the opposing surfaces to effect pressure equilibration therebetween. The introducer includes a guide, an engager, and a sliding mechanism. A Eustachian tube method is also provided. The method involves using the above-described kit.

A stent comprising a hollow tubular body, for instance made of polymeric material, extending along and about a longitudinal axis between two opposite open axial ends and having a substantially cylindrical lateral wall delimiting a longitudinal inner conduit; the body comprising a plurality of deformable sections arranged in succession along the axis; each section comprises a plurality of longitudinal portions of the lateral wall and a plurality of radial cuts formed through the lateral wall and which separate the longitudinal portions from one another.

Medical devices and methods for making and using the same. An example medical device may include an elongate tubular member, an endosurgery stent disposed on the outer surface of the tubular member, a push tube slidably disposed along the outer surface of the tubular member, and a push member slidably disposed in a lumen formed in the tubular member. The push member may be coupled to the push tube.

An elongate medical device is provided. The device includes an elongate member defining a lumen through proximal, central, and distal portions. The central portion of the elongate member is defined from a plurality of closely aligned coils that establish the lumen within the central portion. The central portion further comprises a jacket disposed around a majority of an outer circumference of the plurality of coils, the jacket defining opposing first and second longitudinal edges that extend along the length of the central portion, and an elongate gap between opposing first and second longitudinal edges exposing portions of each of the plurality of coils aligned therewith, wherein the elongate gap allows for fluid communication from within or into the lumen through spaces between neighboring coils and through the elongate gap.

Various embodiments relate to a stent assembly comprising a stent; a swellable coating disposed on at least a portion of an exterior surface of the stent; optionally, a carrier dispersed in the swellable coating and/or disposed on at least a portion of an exterior surface of the stent; and an active agent comprised in at least one of the swellable coating or the carrier, if present. Use of the stent assembly as a ureteric stent, and method of preparing a stent assembly are also provided.
