A ureteral stent that includes a tubular member and a retaining end adapted to be placed inside a kidney or a bladder of a patient. The retaining end includes a plurality of loops. Each of the loops are centered about a loop axis, and two or more of the loop axes extend in different directions relative to other loop axes.

A medical stent including: a tubular main body made of resin that extends along an axis; a first locking member including a first fixed end fixed to the distal end side of the main body, and a first free end positioned radially outward of the main body; a second locking member including a second fixed end fixed to the proximal end side of the main body, and a second free end positioned radially outward of the main body; and a spiral reinforcing material made of metal which is embedded between the inner and outer circumferential surfaces of the main body. The reinforcing material includes a first portion spirally wound between the first and second fixed ends, a second portion spirally wound at a pitch greater than that of the first portion, and a third portion spirally wound at a pitch greater than that of the second portion.

The present disclosure provides collapsible medical devices that are formed from a braided tubular member configured to allow the braided tubular member to be terminated into one or more marker bands while maintaining an open lumen from a proximal end to a distal end. The collapsible medical device including the braided tubular member can be easily pulled down into a delivery sheath or other delivery device so that it is suitable for use with a number of delivery devices. The marker bands, which provide one or more attachment points for a medical device/delivery system, are positioned at one or more locations on the braid such that the braid is fixed and cannot unravel, thus preventing entanglement between individual braid wires and malformation of the device.

A dual opposing helical stent having a furled, small-diameter state and an expanded, large-diameter state. In the furled, small-diameter state, the stent includes a plurality of central lobes arranged at spaced-apart intervals and extending longitudinally defining a stent axis. The stent also includes peripheral lobes formed on the plurality of central lobes. The terminal ends of the stent are welded in a middle section of the stent. A method and technique for manufacturing the stent is also disclosed.

Systems, devices, and methods are provided for the delivery of an implant into the prostatic urethra. Embodiments of delivery systems can include a delivery device for insertion into the patient and a proximal control device for use in controlling release of the implant from the delivery device.

Provided is a stent that can sufficiently support the inner wall of an in vivo lumen from the inside, and that can be easily collected outside the body after the stent completed its role. The stent 1 is delivered from the dissected base of a patient's leg through the inside of a catheter 2 that is a hollow flexible tube. The stent 1 is a coil (support) member that supports the inner wall of an in vivo lumen from the inside while being placed at a treated area in the in vivo lumen. The stent 1 takes an elongate form to elongate along the inside of the catheter 2 by pulling the stent 1 in a longitudinal direction and a coil form to support the inner wall of an in vivo lumen from the inside by releasing the stent 1. The stent 1 also has a hook 1b for collection at its one end.

The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices, systems, and methods for delivering a barrier device within a body lumen of a patient, such as the GI tract. For example, a barrier device may include a distal self-expanding stent. A tubular barrier may have a proximal end, a distal end, and a lumen extending therethrough. The distal stent may be disposed at the distal end of the tubular barrier. An anchoring self-expanding stent may be disposed at the proximal end of the tubular barrier.

Benign prosthetic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland. Treatment options for BPH include medication, surgery (e.g., removal of enlarged prostate tissue), and minimally invasive procedures (e.g., needle ablation, electrovaporization, thermotherapy, and stent insertion). Minimally invasive procedure is typically the preferred choice if medication is ineffective. Accordingly, disclosed herein are system and method for treating BPH using improved implant and delivery device. Certain embodiments of the delivery device can include: a camming barrel having a first groove at the distal end of the camming barrel; a sheath, located within a lumen of the camming barrel, for storing the implantable device; and a first cam follower coupled to the sheath.
