Abstract:
1. A device for accessing a target tissue mass containing a lesion in the body of a patient, comprising: a. an elongate shaft having a proximal section, a distal section, a distal end and a tissue penetrating distal tip; b. a first plurality of conducting members disposed in the elongated shaft and movable between a retracted position in which they are contained within the elongate shaft, and a deployed position in which they initially exit the elongated shaft toward the distal end and extend radially from the elongate shaft at a location proximal to the distal end to a first radial distance; c. a first electrical conductor which is connected to at least one of the first plurality of conducting members and which is configured to be connected to a high frequency electrical power source; d. a second plurality of conducting members disposed in the elongate shaft proximal and movable between a retracted position in which they are contained within the elongate shaft, and a deployed position in which they initially exit the elongated shaft toward the proximal end and extend radially from the elongate shaft at a location proximal to the distal end to a second radial distance; and e. a second electrical conductor which is connected to at least one of the second plurality of conducting members and which is configured to be connected to a high frequency electrical power source.
