摘要：
MICROWAVE ANTENNA ASSEMBLY AND METHOD OF USING THE SAME 5 A microwave antenna assembly (10) comprising an elongate shaft (12) having proximal and distal ends (12a) and a lumen defined therebetween, a conductive member (14) at least partially disposed within the inner lumen of elongate shaft (12), conductive member (14) being selectively deployable relative to a distal end (12a) of elongate shaft (12) from a first condition wherein a distal end (14a) of conductive member (14) at least io partially abuts the distal end (14a) of elongate shaft (14) to a second condition wherein the distal end of conductive member (14) is spaced relative to the distal end (12a) of elongate shaft (12) and a first dielectric material (28) disposed between elongate shaft (12) and conductive member (14), wherein a portion of conductive member (14) is distal to the distal end (12a) of elongate shaft (12) and adapted to penetrate tissue. 16 12a -- '- C24 12 12a 29 34 2214a 1
