A catheter system and a recapture assembly for the catheter system which serves to expand the system's functionality to support highly-articulated implant recapture. The recapture assembly comprises: a cinch tube with a centering device provided at the distal end of the cinch tube and a tether located within the cinch tube adapted to be telescoped relative to the cinch tube. Also, a method for retrieval of the implant comprising a hitch-like element at its proximal end by the catheter system is disclosed.

A tissue-removing catheter for removing tissue in a body lumen includes an elongate body having an axis and proximal and distal end portions spaced apart from one another along the axis. The elongate body is sized and shaped to be received in the body lumen. A handle is mounted to the proximal end portion of the elongate body and operable to cause rotation of the elongate body. A tissue-removing element is mounted on the distal end portion of the elongate body. An inner liner is received within the elongate body and coupled to the handle at a proximal end of the inner liner. A sensor is arranged with respect to the elongate body and inner liner and is configured to detect wear of the inner liner caused by the elongate body contacting the inner liner during use.

A system for treating a patient comprises a delivery device and injectate. The delivery device comprises an elongate shaft with a distal portion and at least one delivery element positioned on the elongate shaft distal portion. The delivery device is constructed and arranged to deliver the injectate through the at least one delivery element and into tissue to create a therapeutic restriction in the gastrointestinal tract. Methods of creating a therapeutic restriction are also provided.

A bifurcated catheter and methods of use are disclosed herein. The bifurcated catheter can include a fixed flat wire that is configurable as a stabilization wire. The bifurcated catheter can be configured to improve the initial access and directability by application of a pull force to the stabilization wire, in addition to a push force from the proximal end of the bifurcated catheter. The stabilization wire is anchored once the bifurcated catheter is positioned. The anchored, bifurcated catheter provides stability and pushability to assist the procedural catheter in traversing the tortuous peripheral vasculature.

An airway visualization system is described herein having an elongate delivery sheath and defining at least one lumen therethrough, wherein the length is positionable within an airway of a subject. An isolation component positioned near or at a distal end of the elongate delivery sheath is expandable to at least partially obstruct the airway and a controller is in communication with the delivery sheath. The controller is also configured to manipulate a fluid flow through the at least one lumen whereby a pressure change within the airway of the subject is imparted sufficiently to at least partially expand or collapse the airway to alter the density of the airway.

Disclosed herein is a catheter for delivering an implantable medical lead to an implantation site near an ostium leading to a proximal region of a coronary sinus. The catheter includes a distal end, a proximal end opposite the distal end, a tubular body extending between the distal and proximal ends, an atraumatic fixation structure defining a distal termination of the distal end, and a lead receiving lumen. The atraumatic fixation structure is configured to enter the ostium and passively pivotally anchor with the proximal region of the coronary sinus. The lead receiving lumen extends along the tubular body from the proximal end to an opening defined in a side of the tubular body near the distal end and proximal the atraumatic fixation structure.

In some examples, a catheter includes a hub assembly, an elongate member, and a plurality of support wires extending along a length of the elongate member. The plurality of support wires is configured to expand radially outward from the elongated body to help anchor a distal portion of the catheter within the vasculature the patient and provide a backup support to the elongate member, e.g., to reduce pushback on the catheter when a treatment device is advanced past the distal tip of the catheter.

A telescoping catheter is provided such as for distal neurovascular aspiration or access. The catheter includes an elongate, flexible tubular body, having a proximal section with at least one lumen and a distal section which is axially movably positioned within the lumen. A control is provided for advancing the distal section from a first, proximally retracted position within the proximal section to a second extended position, extending distally beyond the proximal section. The distal end of at least one of the proximal and distal sections may be provided with at least one active feature, such as at least one movable jaw or rotatable agitator, to assist in the capture of vascular obstruction. The jaw may be operable in response to application of pulsatile negative pressure through the catheter.

Dual-access site catheter systems with a blade or scoring functionality entering through a first access site and a balloon functionality for manipulating or driving the blade or scoring functionality through a different site. The blade or scoring functionality also sometimes provides needle or fluid delivery functionality to an atherosclerotic lesion.

A positioning device is configured to selectively position or otherwise manipulate one or more organs within the body of a subject. The positioning device includes a shaped expandable element that is configured to be selectively transitioned between an unexpanded, or collapsed, state and an expanded state. While in the expanded state, the expandable element repositions or otherwise manipulates an organ. Systems that include positioning devices are also disclosed, as are methods for positioning or otherwise manipulating organs.
