Abstract
Devices and systems 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 one or more energy delivery elements configured to deliver therapeutic energy to nerves proximate a vessel wall.
Claims18
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;
- an energy delivery element positioned along the distal portion of the shaft;
- and
- a plurality of deflectable members spaced apart about a circumference of the distal portion of the shaft, wherein each of the deflectable members is configured to transform from a low-profile state to a deployed state, thereby bending the distal portion and placing the energy delivery element in apposition with a wall of the body vessel.

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 deflectable member at the distal portion of the shaft and electrically coupled to the proximal portion, wherein the deflectable member comprises a bimetallic strip including a first material having a first CTE positioned adjacent a second material having a second CTE that is different than the first CTE;
- and
- an energy delivery element on the deflectable member,
- wherein heating the deflectable member deforms the deflectable member, thereby placing the energy delivery element in apposition with a wall of the body vessel.
