Abstract
According to various embodiments, systems, devices and methods for modulating targeted nerve fibers (e.g., hepatic neuromodulation) or other tissue are provided. The systems may be configured to access tortuous anatomy of or adjacent hepatic vasculature. The systems may be configured to target nerves surrounding (e.g., within adventitia of or within perivascular space of) an artery or other blood vessel, such as the common hepatic artery.
Claims20
A method of ablating nerves surrounding a blood vessel comprising:
- inserting a neuromodulation device within a blood vessel, the neuromodulation device comprising:
- a catheter including an expandable element at a distal portion of the catheter, and
- a therapeutic element within the expandable element, the therapeutic element configured to deliver energy to one or more nerves proximate the blood vessel,
- wherein the therapeutic element is configured to act as a lesion spacing indicator;
- positioning the therapeutic element at a first treatment location within the blood vessel;
- causing the therapeutic element to deliver energy at the first treatment location;
- repositioning the neuromodulation device axially within the blood vessel to a second treatment location based on a dimension indicated by the lesion spacing indicator such that the second treatment location is spaced apart from the first treatment location by at least a minimum threshold spacing;
- and
- causing the therapeutic element to deliver energy at the second treatment location.
6 more elements
A method comprising:
- delivering, by an ultrasound transducer positioned within an expandable element expanded within a blood vessel at a first treatment location, energy sufficient to ablate one or more nerves;
- and
- delivering, by the ultrasound transducer positioned within the expandable element expanded within the blood vessel at a second treatment location, energy sufficient to ablate one or more nerves a second treatment location, wherein the second treatment location is spaced apart from the first treatment location by at least a minimum threshold spacing defined by the ultrasound transducer.
