Abstract
A flexible instrument comprises an antenna having a distal tip portion shaped to perforate tissue, a proximal base, and an antenna body therebetween. The antenna body comprises a patterned cylindrical structure having antenna body elements spatially separated from each other and having a proximal end coupled to the proximal base and a distal end coupled to the distal tip portion. The distal tip portion is disposed distally of the distal end. The antenna comprises a first material having a flexible plastic deformation limit and a second material plated onto the first material. The second material is more conductive than the first material. The flexible instrument further comprises an adjustment device configured to adjust pitch lengths between adjacent antenna body elements and is configured to generate a radiation pattern from the antenna that varies based on the pitch length between the adjacent antenna body elements to ablate tissue.
