  • Publication number: 20200000319
    Abstract: 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.

  • Publication number: 20170020395
    Abstract: 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.

  • Publication number: 20150250382
    Abstract: In vivo visualization systems are described which facilitate tissue treatment by a user in utilizing real time visualized tissue images with generated three-dimensional models of the tissue region of interest, such as the left atrial chamber of a subject's heart. Directional indicators on the visualized tissue as well as the imaging systems may be utilized while other variations may utilize image rotation or manipulation of visualized tissue regions to facilitate catheter control. Moreover, visualized tissue regions may be combined with imaged tissue regions as well as navigational information to further facilitate tissue treatments.

  • Patent number: 8333012
    Abstract: Electrode placement and connection systems are described which allow for the electrical connection and maintenance of one or more electrodes positioned on a substrate which is subjected to a variety of mechanical stresses. Such a system may include an imaging hood having an aperture through which transparent fluid is flowed and one or more electrodes positioned along or about the hood. As the hood is configured between a low-profile and opened configuration, these electrodes may remain electrically coupled despite the mechanical stresses subjected to the electrodes and the connections thereto.

  • Publication number: 20100256629
    Abstract: Methods and devices for treatment of the ostium are described herein. Examples of such devices include inflatable balloons which have one or more raised pores along a distal portion which act as conduits for providing saline flow from the balloon to facilitate visualization of the contacted tissue as well as providing for a conduction path for energy delivery. The balloon may be configured in various shapes to facilitate contact of the balloon in and against the ostium.

  • Publication number: 20100204561
    Abstract: Imaging catheters having irrigation capabilities are described herein. Generally, the device may include a first inner membrane which is sealed and serves to position the device within or relative to a lumen. This balloon structure, when filled with fluid, expands and is engaged in direct contact with the tissue. A second (outer) membrane is not completely sealed and instead provides a pathway for delivery of fluid at the treatment site for effecting various treatments. Imaging systems, optionally articulatable, may be positioned within the balloon as well as electrodes positionable upon the balloon may be utilized to facilitate tissue treatments.
