Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include an endoscope and a backstop delivery device extendable through the endoscope. The backstop delivery device may deliver a backstop to a location of selected tissue for resection. A backstop may include a covering being deployable in a patient. The covering may have one or more anchoring mechanisms disposed on an edge of the covering. A tissue resecting device may be extendable through the endoscope for resecting the selected tissue for resection. The covering may be deployable to an outer surface of the body lumen, such that the anchoring mechanism may secure the covering to the outer surface of the body lumen and the covering may expand to cover the selected tissue for resection.

Devices, systems, and methods for tissue resection

Example medical devices are disclosed. An example medical device includes an elongate member having a proximal end region, a distal end region and an outer surface. The medical device also includes a plurality of filaments braided together in a first braided pattern along a first braided region of the elongate member, wherein the plurality of filaments extend continuously to a second braided region along the elongate member, wherein the plurality of filaments along the second braided region form a second braided pattern different from the first braided pattern.

Guide catheter with reinforcing member

A clip for reducing a dimension of an opening in tissue may include a continuous member having a plurality of legs and a plurality of preformed bends connecting adjacent legs, wherein the plurality of legs form: a first group having two protrusions; a second group having two protrusions; and a third group having two protrusions, wherein each protrusion of each group includes two legs of the continuous member and a corresponding preformed bend connecting the two legs, and each protrusion of each group extends from a region adjacent a first end of the clip to a region adjacent a second end of the clip.

Devices and methods for reducing a dimension of openings in tissue

Systems and methods for treating tissue may include one or more delivery devices, a grasping element, a first ring for anchoring to a wall of a gastrointestinal tract, and a second ring operably couplable to a radially inward surface of the first ring. Other embodiments include methods of treating tissues, including tubular tracts of tissue, comprising coupling a first ring to first tissue of a wall of a tissue tract, relocating a target tissue proximally to a position proximal to the first ring, coupling a second ring to the first ring, and cutting tissue proximal to the interface of the first and second rings.

Systems and related methods for tissue treatment

Stent delivery systems and methods for making and using the same are disclosed. An example stent delivery system may include an inner member. A deployment sheath may be disposed about the inner member. A stent may be disposed between the inner member and the deployment sheath. The deployment sheath may include a translucent reinforcing member that allows for visualization of the stent during stent deployment.

Stent delivery systems with a reinforced deployment sheath

A guide catheter may include a tubular member having an inner layer defining a lumen extending therethrough, a reinforcing braid disposed about the inner layer, a plurality of steering wires interwoven through the reinforcing braid, and an outer layer disposed about the reinforcing braid. At least a portion of the reinforcing braid may be embedded within the outer layer. An introducer sleeve may be slidably disposed over the tubular member. A flush port element may be operably connected to the introducer sleeve.

Integrated catheter system

An intravascular catheter is disclosed that includes an elongated shaft defined by a wall including at least one port extending through the wall into a lumen. At least one channel may be defined between layers of polymer making up the catheter shaft. The channel extends along at least a portion of the shaft and is in fluid communication with the port. Outer and inner diameters of the catheter may be substantially constant along the length of the catheter.

Crescent channel dye flow enabled guide catheters

A method of making a multi-lumen catheter may include disposing an outer surface of a mandrel against an outer surface of a first catheter; disposing a first heat shrink material around the first catheter and the mandrel; heating the first catheter and the mandrel to form a U-shaped channel along the outer surface of the first catheter; removing the first heat shrink material and the mandrel from the first catheter; placing a second catheter into the U-shaped channel; disposing a second heat shrink material around the first catheter and the second catheter such that the second catheter is retained within the U-shaped channel; and heating the first catheter and the second catheter to cause reflow between the first catheter and the second catheter to form the multi-lumen catheter.

Multi-lumen catheters and related methods of manufacture

An intravascular balloon catheter having an ultra soft tip. The catheter includes a braided reinforcement member extending substantially the length of the elongate shaft. A balloon is disposed at the distal end of the elongate shaft. An ultra soft tip is formed from a distal portion of balloon material extending distal of the distal end of the elongate shaft.
