Abstract: A stent delivery system including an elongate shaft of a medical device, a stent selectively coupled to a distal portion of the elongate shaft, and a coupling mechanism for selectively coupling the stent to the elongate shaft by inserting a tab on one of the stent or the elongate shaft into an opening in the other of the stent or the elongate shaft. The tab may be deflected from a first position to a second position to disengage the tab from the opening.

Abstract: A tumor ablation device may be combined with a diagnostic tool and/or a surgical instrument for offering cancer treatment therapy.

Abstract: A tissue resection device for resecting tissue from a target site within a patient's body. The device includes an elongate shaft having a proximal end and a distal end. An actuation member extends partially through the shaft, and reciprocates within the shaft between a retracted position and an extended position. Multiple snare wires extend through the actuation member, and emerge outwards from a distal portion of the actuation member. The snare wires cooperate and join to form a snare loop, which engages the tissue intended to be resected. The snare loop is configured to enhance friction while engaging the tissue, to resect the tissue.

Abstract: A rotatable connection between a tubular member and an elongate wire of a catheter for allowing rotational movement of the tubular member relative to the elongate wire. The rotatable connection includes a first tube secured to the tubular member and a second tube secured to the elongate wire. The second tube is disposed around the first tube and rotatable relative to the first tube. The longitudinal axis of the tubular member is offset from the longitudinal axis of the elongate wire to allow a guidewire to extend through the tubular member and along the side of the elongate wire.

Abstract: A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and an interference fit member for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft by an interference fit between the interference fit member and the drainage stent such that axial movement of the elongate shaft relative to the drainage stent moves the interference fit member from a first position in which the interference fit member is engaged with the drainage stent and forms an interference fit with the drainage stent to a second position in which the interference fit member is disengaged from the drainage stent.

Abstract: A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and a locking mechanism for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft such that the proximal end of the stent is positioned proximal of the distal end of the elongate shaft. The locking mechanism includes an engaging feature of the elongate shaft which engages a portion of the stent such that the stent may be selectively coupled to the elongate shaft through rotational motion of the elongate shaft relative to the stent. In some instances, the engaging feature of the elongate shaft may be a tab which extends into an opening of the stent.

Abstract: Stent delivery systems, components thereof, and methods for making and using stent delivery systems and components are disclosed. An example combination device may function as both an anchoring mechanism cover and a guidewire lock. The combination device may include a tubular body. The tubular body may define an inner diameter and may have a locking portion. The inner diameter may be sized to fit about an outer diameter of a drainage stent having an anchoring mechanism. The locking portion may be configured to secure the position of a guidewire relative to a catheter system.

Abstract: The present invention includes a braided stent and method of making the same. The braided stent has an integral retrieval and/or repositioning member. The stent includes a first open end, a second open end and a tubular body therebetween. The retrieval and/or repositioning member extends from and is interbraided into the braided tubular body. The retrieval and/or repositioning member includes an elongated portion extending from the first open end and a second section interlooping circumferentially about the first open end such that force exerted on the elongated portion causes radially contraction of the stent end and stent body.

Abstract: Endoscope assemblies and methods for making and using the same. An example endoscope assembly may include an endoscope having a channel formed therein and a port that provides access to the channel, a cap disposed on the port, and an attachment assembly coupled to the cap. The attachment assembly may include a base and one or more arms extending from the base. A locking member may be coupled to at least one of the one or more arms.
