The present disclosure relates generally to devices, systems, and methods for extracting ureteral stent from a patient. Some embodiments are particularly directed to an extraction tool capable of extending into a urethra and retrieving a stent without scope visualization, assistance from a medical professional, and/or prescription medication (e.g., for pain). The extraction tool may be a single-use tool having an end effector configured to capture a proximal portion of a stent. In several embodiments, the extraction tool be utilized in conjunction with a stent assembly having a band coupled to a proximal retention member of the stent.

An application device has a ureteral catheter with a ureteral catheter main body, a receiving body connected to the ureteral catheter main body by means of at least one connection element of the ureteral catheter, and an introduction component for holding the ureteral catheter and for guiding the ureteral catheter through a ureter of a patient along a pliable guide element. The ureteral catheter can be displaced by means of the introduction component in opposite directions of movement along the pliable guide element and the introduction component is designed to guide the ureteral catheter main body and the receiving body during displacement in the respective directions of movement.

The present disclosure is directed to methods, compositions, devices and kits which pertain to the attachment of stent-containing medical devices to tissue.

The present disclosure provides an endoprosthesis where a preferably polymeric coating has a number of surface features such as protrusions or textures that are arranged in a micropattern. The endoprosthesis optionally has an expanded state and a contracted state, and in some cases includes a stent with a polymeric coating attached to an outer surface of the stent. The stent may have an inner surface defining a lumen, an outer surface, and a stent thickness defined between the inner surface and outer surface. The stent may comprise a plurality of surface textures extending from the stent surfaces, wherein the textures are arranged in a macropattern.

A fully absorbable stent for treating lesions in vessels in the body has a flexible covering and expandable belts. The device is formed from very low inflammation response materials that are fully absorbed in 3 to 12 months. The expandable belts provide radial forces for keeping the vessel open following balloon angioplasty.

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.

A body of a device for positioning a coronary stent or a coronary balloon within coronary arteries is described. The body is formed of a front part and a rear part. The front body part represents, on the one side, a truncated part having a tubular extension with a cutout for connection to a Y-connector and, on the other side, successively passes into a cylindrical part, a cylindrical smooth part of a smaller diameter and a runner guide. The smooth surface of the rear body part is housed over the cylindrical smooth front body part, and the inside surface provided with the circumferential double-thread for engaging with the runner protrusions is housed over the runner. Through-holes for introducing the coronary stent or coronary balloon delivery system inside the device housed in the body are formed in the tubular extension of the front body part.
