Abstract
The invention generally relates to devices and methods that allow an operator to obtain real-time images of a luminal surface prior to, during, and after an intraluminal procedure, including while a tool is engaged with the luminal surface. An imaging system of the invention may include a first elongate member that includes a first imaging element and a catheter that includes a second imaging element. The first imaging element is an optical-to-acoustic transducer, and the second imaging element is an optical-to-acoustic transducer. The catheter also defines a lumen and includes an ablation element. The catheter is configured to receive at least a portion of the elongate member within the lumen and is configured to move along a path of the elongate member.
Claims25
1) An imaging and ablation system comprising
- an elongate member comprising at least one first imaging element, wherein the first imaging element includes a first acoustic-to-optical transducer;
- and
- a catheter defining a lumen and comprising at least one second imaging element and an ablation element, wherein the catheter is configured to receive at least a portion of the elongate member within the lumen and is configured to move along a length of the elongate member, and the second imaging element includes a second acoustic-to-optical transducer.
15) A method for an intraluminal treatment, the method including the steps of
- introducing an elongate member into a lumen, wherein the elongate member comprises at least one first imaging element and the first imaging element includes a first acoustic-to-optical transducer;
- imaging a surface of the lumen with the elongate member to locate a treatment area;
- guiding a catheter over at least a portion of the elongate member towards the treatment area, wherein the catheter comprises at least one second imaging element and an ablation element, and the second imaging element includes a second acoustic-to-optical transducer;
- imaging the surface, as the catheter is guided towards the treatment area, to place the catheter for ablation;
- and
- energizing the ablation element, once the catheter is placed, to ablate the treatment area.
