Abstract
A catheter for ablating and imaging tissue includes a porous electrode structure comprising an interior region for receiving a conductive medium, an elongate tube having a distal tube end that extends within the interior region, and an ultrasonic transducer assembly housed within the distal tube end.
Claims19
An ablation/imaging catheter, comprising:
- an elongate tube having a distal tube end;
- a porous electrode structure mounted to the distal tube end and comprising an interior region for receiving a conductive medium, the distal tube end extending within the interior region;
- an electrode in communication with the interior region for delivering electrical energy to the conductive medium within the interior region;
- and
- an ultrasound transducer assembly housed within the distal tube end.
2 more elements
An ablation/imaging catheter, comprising:
- an elongate tube having a distal tube end;
- an electrode structure mounted to the distal tube end;
- and
- an imaging element positionable distal to the distal tube end within an interior region of the electrode structure, wherein the imaging element is configured to emit energy through the distal tube end and electrode structure to produce an image, and the distal tube end and electrode structure are substantially transparent to the imaging energy.
1 more element
An ablation/imaging catheter, comprising:
- an elongate tube having a distal tube end;
- a porous electrode structure on the distal tube end and comprising an interior region for receiving a conductive medium therein;
- a source of conductive medium connected to the elongate tube for delivering conductive medium into the interior region of the porous electrode structure such that energy may be delivered via the conductive medium to tissue outside the porous electrode structure;
- and
- an ultrasound transducer assembly within the distal tube end.
