Abstract
A surgical device has an integral first tip having pair of electrodes configured to ablate tissue using electric energy. A second tip has a pair of electrodes configured to provide pacing signals to a heart and/or to sense electrical signals passing through heart tissue. The second tip is configured to snap onto the first tip, such that the same device may be used for ablation, pacing, and sensing. Alternatively, the second tip may be integral with the device and the first tip configured to snap onto the second tip. Alternatively, a single integral tip of the surgical device may be used for ablation, pacing, and sensing. Such a multipurpose tip may comprise a plurality of electrode pairs or an array of electrodes. A user interface on the device or elsewhere may be operable to provide selectable modes for selectively varying properties of signals communicated to the electrodes.
Claims
AMENDED CLAIMS + STATEMENT UNDER ARTICLE 19 (1) received by the International Bureau on 23 Octobre 2007 (23.10.2007).
14. The surgical device of claim 1 , wherein the electrodes of one or both of the first tip portion or the second tip are further operable to sense electrical signals passing through tissue positioned adjacent to the electrodes.
15. The surgical device of claim 1 , further comprising; a) a power source operable to communicate electrical signals to the conductors; and b) a user interface operable to receive user selections of modes, wherein the selectable modes comprise ablation mode and pacing mode, wherein the user interface is operable to provide a signal to the electrodes of one or both of the first tip portion or second tip in accordance with user mode selections.
16. A surgical device for treatment of tissue, the tissue having a tissue surface, the surgical device comprising: a) a handle; b) a head connected to the handle, wherein the head comprises a first tip portion, wherein the first tip portion comprises a pair of electrodes, wherein the electrodes are operable to pace a heart using an electrical pacing signal when the electrodes are placed adjacent to the heart; c) a shaft positioned between the handle and the head; d) a pair of conductors, wherein each conductor is in communication with a respective one of the pair of electrodes of the first tip portion, wherein at least a portion of the pair of conductors Is positioned within the shaft; and e) a second tip, the second tip comprising a pair of electrodes, wherein the second tip is configured to be removably secured to the first tip portion, wherein the electrodes of the second tip are operable to ablate tissue.
17. The surgical device of claim 16, wherein the first lip portion is selectably removable from the head.
