Abstract
A surgical method and apparatus for positioning a diagnostic or therapeutic element within the body. The apparatus may be catheter-based or a probe including a relatively short shaft.
Claims20
A soft tissue coagulation probe, comprising:
- a relatively short shaft defining a distal end and a proximal end;
- a handle associated with the proximal end of the shaft;
- and
- at least two longitudinally spaced soft tissue coagulation electrodes associated with the shaft and located in spaced relation to the handle, the respective size and spacing of the at least two soft tissue coagulation electrodes being such that simultaneous transmission of energy thereby to an indifferent electrode will produce an area of coagulated tissue that spans the at least two soft tissue coagulation electrodes.

A soft tissue coagulation probe, comprising:
- a relatively short malleable shaft defining a distal end and a proximal end;
- a handle associated with the proximal end of the malleable shaft;
- a plurality of longitudinally spaced soft tissue coagulation electrodes operably connected to the malleable shaft and located in spaced relation to the handle;
- and
- a temperature sensor located at the longitudinal end edge of at least one of the soft tissue coagulation electrodes.

A surgical device, comprising:
- a malleable shaft defining a distal end and a proximal end;
- a handle associated with the proximal end of the malleable shaft;
- and
- a distal tip assembly connected to the distal end of the malleable shaft, the distal tip assembly including a distal member and a plurality of longitudinally spaced operative elements carried by the distal member, the distal member being one of flexible, somewhat flexible and malleable.
