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 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., 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 or of vascular structures that feed or perfuse the neural fibers.

Catheter apparatuses having multi-electrode arrays for renal neuromodulation and associated systems and methods

The present disclosure relates to devices, systems and methods providing evaluation and feedback to an operator of a device providing neuromodulation treatment, such as modulation of renal nerves of a human patient. In one embodiment, for example, a system monitors parameters or values generated before treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of various electrical properties associated with an electrode carried by a catheter. The electrode measures an electrical property of biological material making contact with the electrode while deploying the electrode, the electrical property being dependent on a ratio of a wall-interface area to a fluid-interface area.

Devices, systems, and methods for monitoring and/or controlling deployment of a neuromodulation element within a body lumen and related technology

An apparatus for sealing a puncture through a vessel wall including a positioning assembly, a sheath releasably engaged with the positioning assembly, and a support member axially advanceable through the sheath. The positioning assembly includes a positioning element positioned at a distal portion of the positioning assembly and a sealant disposed at a distal portion of the positioning assembly. The sheath guides the sealant and positioning assembly to the puncture in the vessel wall.

Apparatus and methods for sealing a vascular puncture

In embodiments of the invention, the invention comprises a light tip cable including a cartridge assembly affixed to a medial end of the cable, the cartridge assembly including an emitter housing where the emitter housing includes an opening at a medial end of the housing and a flange at a lateral end of the housing. In embodiments of the invention, the cartridge assembly includes a light emitting element in the housing extending to the opening, retention features covering at least a portion of the housing, including the flange, the retention features comprising a lateral face and a lobe and at least one load bearing strand extending from the cable to the emitter; and electrical connectors extending from the cable to the light emitting element.

Hearing aid connector

A neuromodulation catheter includes an elongate shaft and a neuromodulation element. The shaft includes two or more first cut shapes and two or more second cut shapes along a helical path extending around a longitudinal axis of the shaft. The first cut shapes are configured to at least partially resist deformation in response to longitudinal compression and tension on the shaft and torsion on the shaft in a first circumferential direction. The second cut shapes are configured to at least partially resist deformation in response to longitudinal compression on the shaft and torsion on the shaft in both first and second opposite circumferential directions.

Catheters with enhanced flexibility and associated devices, systems, and methods

Apparatus and method for sealing a vascular puncture

Described here are devices and methods for forming shock waves. The devices may comprise an axially extending elongate member. A first electrode pair may comprise a first electrode and a second electrode. The first electrode pair may be provided on the elongate member and positioned within a conductive fluid. A controller may be coupled to the first electrode pair. The controller may be configured to deliver a series of individual pulses to the first electrode pair, where each pulse creates a shock wave. The controller may cause current to flow through the electrode pair in a first direction for some of the pulses in the series and in a second direction opposite the first direction for the remaining pulses in the series.

Shock wave device with polarity switching

Helical push wire electrodes are provided. The electrodes may create a continuous helical lesion. One or more electrodes may wind around a support section and create a set of helixes having fixed ends and hitches. Pushing or pulling an end of the electrode transforms the electrodes between a delivery configuration and a deployed configuration such that the set of helixes expand or contract axially. Different portions of the electrodes may be surrounded by sleeves. The sleeves may regulate how the wires transform and provide insulation. Various insulation configurations of the electrodes may provide creations of discrete lesions, efficient energy delivery and reduced power consumption.
