Abstract: A surgical probe includes a connection hub, an antenna assembly, and an outer jacket. The antenna assembly is coupled to the connection hub, extends distally from the connection hub, and includes a radiating portion coupled thereto at the distal end thereof. The radiating portion is configured to deliver energy to tissue to treat tissue. The outer jacket is coupled to the connection hub, extends distally therefrom, and is disposed about the radiating portion. The outer jacket includes a distal end member configured to be spaced-apart from the radiating portion a target axial distance. One or more of the couplings between the antenna assembly and the connection hub, the radiating portion and the antenna assembly, and the outer jacket and the connection hub defines a flexible configuration permitting axial movement therebetween to maintain the target axial distance between the radiating portion and the distal end member.

Abstract: Provided is an improved method for forming lithium ion cathode materials specifically for use in a battery. The method comprises forming a first solution comprising a digestible feedstock of a first metal suitable for formation of a cathode oxide precursor and a multi-carboxylic acid. The digestible feedstock is digested to form a first metal salt in solution wherein the first metal salt precipitates as a salt of deprotonated multi-carboxylic acid thereby forming an oxide precursor. The oxide precursor is heated to form the lithium ion cathode material.
