  • Patent number: 9603659
    Abstract: Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon can have a composite structure with a non-conductive section and a conductive section. A method for fabricating a semi-permeable ablation balloon using ionizing radiation and an etching process is also disclosed.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: March 28, 2017

  • Patent number: 9463064
    Abstract: Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon is configured to transmit the RF energy in a direction distally towards a leading end of the ablation device. Multiple ablation electrodes on the device can be used for providing lesions of different size or shape.

  • Patent number: 9370329
    Abstract: A system for performing mapping and ablation functions includes a catheter sized and shaped for vascular access. The catheter includes an elongate body extending between a proximal end and a distal end. A tip section positioned at the distal end of the catheter body and includes a proximal portion and a distal portion. One or more electrode structures are formed on an exterior surface of the tip section. The one or more electrode structures each includes a mapping electrode at the distal portion of the tip section and a contact pad electrically coupled to the mapping electrode.

  • Patent number: 9211156
    Abstract: A system for performing mapping and ablation functions includes a catheter sized and shaped for vascular access. The catheter includes an elongate body extending between a proximal end and a distal end and having at least one inner fluid lumen. The catheter further includes a tip section positioned proximate to the distal end of the body. The tip section includes a proximal portion and a distal portion. The distal portion can have a distal end that can be substantially planar. The system also includes one or more electrode structures exposed at the tip section such that the one or more electrode structures disposed proximate the substantially planar distal end of the tip section.
