A neuromodulation catheter in accordance with a particular embodiment includes an elongate shaft and a neuromodulation element operably connected to the shaft. The shaft includes a proximal hypotube segment at its proximal end portion and a jacket disposed around at least a portion of an outer surface of the hypotube segment. The jacket may be made at least partially of a polymer blend including polyether block amide and polysiloxane. The neuromodulation element includes a distal hypotube segment and a tubular jacket disposed around at least a portion of an outer surface of the distal hypotube segment. The jacket has reduced-diameter segments spaced apart along its longitudinal axis. The neuromodulation element further includes band electrodes respectively seated in the reduced-diameter segments and respectively forming closed loops extending circumferentially around the jacket.

Neuromodulation catheters having jacketed neuromodulation elements and related devices, systems, and methods

Delivery devices for delivery of a stented prosthetic heart valve. Various delivery devices include an outer sheath assembly including an outer sheath connected to a capsule that is advanced proximally to retain the prosthetic valve, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper to provide a smooth transition of the capsule over the prosthetic valve during loading and recapture procedures. The bumper is expandable from a first position to a second position in which a distal end of the bumper is expanded to increase its diameter. The bumper can be biased in the second, expanded position so that the bumper automatically transitions to the expanded position upon retraction of the outer sheath.

Stented prosthetic heart valve delivery system having an expandable bumper

Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a covering feature associated with the spindle for selectively covering at least a portion of a stented prosthetic heart valve tethered to the spindle in a delivery state. In some embodiments, the covering feature includes a tip mounted to the spindle. The tip can include an overhang region for selectively covering a portion of the stented prosthetic heart valve. In other embodiments, the tip can include a tip body and a compressible foam bumper. In yet other embodiments, the covering feature includes an outer sheath arranged to selectively cover the stented prosthetic heart valve. The outer sheath can be elastic and stretchable for recapturing a partially expanded prosthesis, for example by including one or more windows covered by a stretchable covering layer.

Transcatheter prosthetic heart valve delivery system with protective feature

Numerous delivery devices for delivery of a stented prosthesis, such as a stented prosthetic heart valve. Various delivery devices include a capsule that is advanced proximally to retain the stented prosthesis, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper or bumper assembly to provide a smooth transition of the capsule over the stented prosthesis. In some alternate disclosed embodiments, the bumper further serves to connect various elements of the inner shaft assembly. Additional embodiments include a bumper assembly arranged and configured to longitudinally expand and contract to substantially fill any open space as the capsule is retracted from the stented prosthesis, which prevents kinking in the capsule. Additional embodiments include proximal and/or distal bumpers for temporarily covering and smoothing the ends of the stented prosthesis as part of a delivery device that does not include a capsule.

Stented prosthesis delivery system having a bumper

The present disclosure relates to numerous devices and methods for transcatheter stented prosthetic heart valve loading and delivery. Such devices and methods reduce suture tangling and also provide the ability to adjust the stented prosthetic heart valve expansion and contraction prior to the final release of the stented prosthetic heart valve from the delivery device.

Devices and methods for transcatheter valve loading and implantation

Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally spiral/helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., spiral/helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function.

Multi-electrode catheter assemblies for renal neuromodulation and associated systems and methods

In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device, the kit comprising an outer sheath, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with a tapered distal end. The inner sheath is slidable within the inner lumen of the outer sheath and is selectably removable from the inner lumen of the outer sheath by sliding the inner sheath out of the proximal opening of the outer sheath. The kit includes an elongated deployment receptacle including a deployment bay slidable within the inner lumen of the outer sheath when the inner sheath is not within the inner lumen of the outer sheath. The deployment bay carries an implantable medical device through the inner lumen of the outer sheath and facilitates deployment of the implantable medical device from the distal end of the outer sheath.

Pass-through implantable medical device delivery catheter with removeable distal tip

A tool for compressing a stented prosthesis. The tool includes first and second sets of rollers. The first set includes a plurality of rollers arranged to define a first working region having a first working diameter. The second set includes a plurality of rollers arranged to define a second working region having a second working diameter. The sets of rollers are arranged such that the working regions are axially aligned. The first working diameter is greater than the second working diameter. A stented prosthesis traversing the first working region and then the second working region is forced to a compressed state. In some embodiments, the tool includes one or more intermediate sets of rollers between the first and second sets of rollers, with each of the intermediate sets of rollers defining a working region having a working diameter. The respective working diameters progressively decrease in a downstream direction.

Method for compressing a stented prosthesis

An inner subassembly of a delivery system assembly extends within a lumen of an elongate outer tube of the assembly, and includes a flared distal end, which is preferably configured to conform to a proximal end of an implantable medical device; a distal-most portion of the outer tube is sized to contain both the flared distal end and an entirety of the medical device. The inner subassembly includes a core, an elongate pull-wire, extending along the core, and a sheath surrounding the pull-wire and the core; the sheath includes a slot opening that allows the pull-wire to pass laterally therethrough. The assembly preferably has a pre-formed curvature along a length of the sheath, and the slot opening extends along the pre-formed curvature. The outer tube is longitudinally moveable relative to the inner subassembly, for example, to deploy the medical device.
