CATHETER APPARATUSES FOR MODULATION OF NERVES IN COMMUNICATION WITH THE PULMONARY SYSTEM AND ASSOCIATED SYSTEMS AND METHODS

摘要

Devices, systems, and methods for the selective positioning of an intravascular neuromodulation device are disclosed herein. Such systems can include, for example, an elongated shaft and a therapeutic assembly carried by a distal portion of the elongated shaft. The therapeutic assembly is configured for delivery within a blood vessel. The therapeutic assembly can include a pre-formed shape and can be transformable between a substantially straight delivery configuration; and a treatment configuration having the pre-formed helical shape to position the therapeutic assembly in stable contact with a wall of the body vessel. The therapeutic assembly can also include a mechanical decoupler operably connected to the therapeutic assembly that is configured to absorb at least a portion of a force exerted on the therapeutic assembly by the shaft so that the therapeutic assembly maintains a generally stationary position relative to the target site.

主权项

1. A catheter apparatus, comprising:
an elongated shaft having a proximal portion and a distal portion, wherein the distal portion of the shaft is configured for intravascular delivery to a body vessel of a human patient; a therapeutic assembly at the distal portion of the elongated shaft comprising a pre-formed shape, and wherein the therapeutic assembly is transformable between—
a substantially straight delivery configuration; anda treatment configuration having the pre-formed helical shape to position the therapeutic assembly in stable contact with a wall of the body vessel; and a mechanical decoupler operably connected to the therapeutic assembly, wherein the mechanical decoupler is configured to absorb at least a portion of a force exerted on the therapeutic assembly by the shaft so that the therapeutic assembly maintains a generally stationary position relative to the target site.
