A flexible microwave antenna assembly for a surgical ablation instrument capable of conforming to a tissue surface for ablation thereof. The ablation instrument includes a transmission line having a proximal portion suitable for connection to an electromagnetic energy source. The antenna assembly includes a flexible antenna coupled to the transmission line for radially generating an electric field sufficiently strong to cause tissue ablation. A flexible shield device is coupled to the antenna to substantially shield a surrounding area of the antenna from the electric field radially generated therefrom while permitting a majority of the field to be directed generally in a predetermined direction. A flexible insulator is disposed between the shield device and the antenna which defines a window portion enabling the transmission of the directed electric field in the predetermined direction. The antenna, the shield device and the insulator are formed for selective manipulative bending thereof, as a unit, to one of a plurality of contact positions to generally conform the window portion to the biological tissue surface to be ablated.
The invention claimed is: 1. An ablation device for forming a lesion in targeted biological tissue, the device comprising: an ablation portion for delivering ablation energy to targeted biological tissue through a window portion in a surface of the ablation portion; a handle portion extending proxi
The invention claimed is: 1. An ablation device for forming a lesion in targeted biological tissue, the device comprising: an ablation portion for delivering ablation energy to targeted biological tissue through a window portion in a surface of the ablation portion; a handle portion extending proximally of the ablation portion; and a grip portion attached to and extending distally from a distal end of the ablation portion is axially offset in a direction toward the window portion to facilitate rotational or translational manipulation of the ablation portion into position relative to the targeted biological tissue. 2. The ablation device according to claim 1 in which the ablation portion and grip portion have similar flexibility. 3. The ablation device according to claim 1 in which the ablation portion includes a high frequency antenna structure disposed therein offset toward the window portion to orient the antenna structure toward biological tissue in position adjacent the window portion.
