Abstract
A tunable ablation delivery device is disclosed. The tunable ablation delivery device includes a housing and a detection element on the housing for detecting a physiological indication. The tunable ablation delivery device further includes an ablation element disposed within the housing. An opening in the housing is positioned relative to the ablation element to facilitate a treatment using the ablation element modality.
Claims26
An ablation energy delivery device, comprising:
- an endoscope body;
- a transmission window configured to transmit ablation energy, the transmission window being movably mounted to the endoscope body;
- a detection element configured to detect a physiological indication;
- and
- an ablation element configured to emit ablation energy, the ablation element disposed to transmit emitted ablation energy through the transmission window,
- wherein the transmission window movably mounted to the endoscope body is selectively positionable relative to the endoscope body and to the ablation element to direct ablation energy emitted from the ablation element through the transmission window to a desired location for treatment using the ablation energy,
- wherein the transmission window is disposed in a housing, the housing being made of a material configured to transmit less ablation energy than the transmission window.

A method of delivering ablation energy to a site within a body, the method comprising:
- positioning an endoscope body comprising an ablation device in proximity to an ablation treatment site;
- detecting, via a detection element, a physiological indication at each of a plurality of positions in the proximity of the ablation treatment site;
- determining at which of the plurality of positions a relative peak of the detected physiological indication is detected;
- rotating a transmission window of the ablation device about a longitudinal axis of the endoscope body to selectively position the transmission window of the ablation device relative to the endoscope body and to an ablation element of the ablation device, the selectively positioning comprising aligning the transmission window with at least the position of the relative peak;
- activating the ablation element of the ablation device to emit ablation energy;
- and
- transmitting the ablation energy emitted from the ablation element through the transmission window.
4 more elements
An ablation energy delivery system comprising:
- an endoscope body comprising an ablation device, wherein the ablation device comprises:
- a transmission window disposed in a housing, portions of the housing surrounding the transmission window being configured to shield against transmission of ablation energy;
- a detector configured to detect a physiological indication at a plurality of positions and to localize a position corresponding to a desired amount of physiological indication;
- and
- an ablation element configured to emit ablation energy and disposed to transmit the ablation energy through the transmission window;
- and
- a control system configured to:
- output a signal to move a position of the transmission window relative to the endoscope body and to the ablation element, and
- output a signal to activate the ablation element to emit the ablation energy form the ablation element, the ablation energy emitted from the ablation element being transmitted through the transmission window to an ablation treatment site at or in a vicinity of the localized position.
