Publication NumberUS 10624695Filing StatusIssued PatentAvailabilityUnknownFiling Date2014-03-26Publication Date2020-04-21
A method of ablating a tissue region within a blood-filled environment comprises restraining a fluid within a visualization field in a portion of the blood-filled environment and visualizing the tissue region through the fluid within the visualization field. The method also includes transmitting ablating electrical energy from the fluid into the visualized tissue region.

A method of inhibiting flow of a purging fluid from a device comprises positioning an imaging hood in proximity to a tissue region to be visualized. The imaging hood includes a distal membrane which defines a main aperture. The imaging hood and the distal membrane define an open area. The method also comprises introducing the purging fluid into a proximal portion of the open area. The proximal portion is bounded by a proximal membrane including a plurality of apertures. The method also compri…

A computer implemented method comprises receiving a model of a tissue region, steering a distal end of a catheter within a body to a first area of a tissue region, and obtaining a first image from the distal end of the catheter of the first area of the tissue region. The method further comprises mapping the first image of the first area of the tissue region to the model of the tissue region and displaying the first image of the first area of the tissue region on the model of the tissue region.

Methods and apparatus for efficient purging from an imaging hood are described which facilitate the visualization of tissue regions through a clear fluid. Such a system may include an imaging hood having one or more layers covering the distal opening and defines one or more apertures which control the infusion and controlled retention of the clearing fluid into the hood. In this manner, the amount of clearing fluid may be limited and the clarity of the imaging of the underlying tissue through…

Image processing systems are described which utilize various methods and processing algorithms for enhancing or facilitating visual detection and/or sensing modalities for images captured in vivo by an intravascular visualization and treatment catheter. Such assemblies are configured to deliver energy, such as RF ablation, to an underlying target tissue for treatment in a controlled manner while directly visualizing the tissue during the ablation process.
