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 has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. The stent also has an anti-migration device used for immobilization of the stent at the target site.

A drainage stent delivery system is disclosed. The drainage stent delivery system includes a catheter body, a stent member, and a coupling member. In some embodiments the coupling member can include keyed connectors having a non-round shape to facilitate a 1:1 rotation ration of the catheter body and the stent member. In another embodiment, the coupling member can include a telescoping connector having an inner tube and a release wire disposed through the inner tube. A distal portion of the release wire has an outer diameter greater than an inner diameter of the inner tube such that the telescoping connector can be displace by the release wire. In another embodiment, the stent member includes a proximal retention member having arms that are outwardly extendable.

A coated urinary catheter or urinary stent device includes a urinary catheter or stent which, in a deployed position, includes or defines a protective surface area and a protected surface area and a coating upon at least a portion of the protective surface area. The coating includes a lubricant and an antimicrobial and/or pH buffering material. The device is configured such that, upon application of negative pressure to the catheter or stent, tissue of a urinary tract of a patient conforms or collapses onto the protective surface area and is thereby prevented or inhibited from occluding one or more protected drainage holes, ports or perforations of the catheter or stent.

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.

A stent (100) comprising a stent wall (102), the stent wall (102) having a plurality of side holes (110) extending therethrough, each side hole (110) having an upstream end (116) and a downstream end (118). The stent wall (102) tapers in thickness in a direction towards the side hole (110) at the upstream (116) and/or downstream (118) end of at least one of the side holes (110). Also disclosed are methods for making side holes (110) in stents (100) by milling and making stents (100) having side holes (110) by injection moulding.

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.

A pyelo-ureteral stent is provided that combines the benefits of a stent having a lumen with the benefits of a lumen-less stent. In one example, the stent may be implanted in a patient for use during and after a pyeloplasty procedure. The provided stent includes a flexible tube having two separate lumens. Each lumen terminates prior to the stent's closed distal end, which enables a lumen-less ureteric limb at the stent's closed distal end. The lumen-less ureteric limb may have a smaller diameter than the rest of the stent, and may be positioned in a patient's ureter to bridge the pyeloplasty repair, thereby providing the benefits of a lumen-less stent. The flexible tube may be formed with at least one perforated coil for the drainage of urine and/or blood. The stent may be removed from the patient without the use of a cystoscopic procedure.

Medical implants that include a containment layer surrounding, or surrounded by, a biodegradable medical device provide the benefit that pieces formed during degradation of the medical device are held within a constrained place and thus do not causes injury to a hosts.

A dilation device for an intrabody lumen, for example, a urethra partially occluded by an enlarged prostate in the form of a curved element configured to be implanted around the lumen and add resilience to the lumen, and a method for dilating such a lumen by implanting a dilation device around the outside of the lumen with at least part of the dilation device embedded in surrounding, thereby preventing clinically significant compression of the lumen. Also, an implantation device for such a dilation device in the form of a mounting device configured to carry the dilation device; and a releasably attached movable holder, with the mounting device and holder configured to deliver the dilation device though a working channel to a desired position in a lumen, and to implant the dilation device through a wall of the lumen to a position surrounding the lumen.

Compositions comprising electrospun fibers and active (e.g. pharmaceutical) agents encapsulated thereto are provided. Further, articles and methods of use of the fibers, including, but not limited to coating of medical tubing, are provided.
