摘要： A coaxial cable (102) for a microwave ablation probe (104) is disclosed. The alation probe (104) has an operating frequency at which microwave energy is delivered to target tissue. The coaxial cable (102) comprises: an inner conductor (202a); an outer conductor (202c); and a dielectric (202b) arranged between the inner conductor and the outer conductor. The outer conductor (202c) comprises a plurality of cut-outs (106). The cut-outs (106) each have a length less than 10% of the wavelength in free-space at the operating frequency of the ablation probe (104). Also disclosed is a microwave ablation system (100) and method (1000) of making a coaxial cable.

摘要： A microwave ablation probe (100). The microwave ablation probe (100) comprises: an applicator (102) arranged to apply microwave radiation to heat surrounding tissue; a feed cable (104) arranged to supply electromagnetic energy to the applicator (102); a tubular shaft (105) arranged to house at least part of the length of the feed cable (104); a coolant flow path (106, 108) via which coolant is able to flow, the coolant flow path being located within a space between the tubular shaft (105) and the feed cable (102); and a choke (112) arranged to reduce power reflected from the applicator (102) along the feed cable (104). The choke comprises one or more bridging structures (114a, 114b, 14c) each provided on a component of the tubular shaft of the feed cable, the one or more bridging structures being arranged to extend across the space between the tubular shaft (105) and the feed cable (104) and form an electrical connection therebetween. The one or more bridging structures (114a, 114b, 114c) each extend only part way around a longitudinal axis of the ablation probe, thereby allowing coolant to flow through the choke (112). The one or more bridging structures (114a, 114b, 114c) are each formed from an angled region cut out from a wall of the component of the tubular shaft or the feeding cable from which they are formed.

摘要： An ablation probe handle (114; 214) for use with an ablation probe (112; 212), the ablation probe being suitable for use with an internal anatomy access system (102), the ablation probe handle (114; 214) comprising: a housing (126; 216) adapted to be gripped by the user; a lead cable connection interface (128; 228) adapted for connection to a lead cable (116; 216) for supplying a source of microwaves, the lead cable connection interface (128; 228) defining a lead cable connection axis (X); an ablation probe mounting (134) adapted to mount the catheter (122; 222) of an ablation probe within the housing (126; 226); a working channel connection interface (130; 230) adapted for connection to a working channel (110; 210) of an internal anatomy access system (102), wherein the catheter (122; 222) of the ablation probe is arranged to extend from the housing (126; 226) along the working channel (110; 210) when the working channel is connected to the handle (114; 214), the working channel connection interface (130; 230) defining a working channel connection axis (Y), and wherein the lead cable and working channel connection axes are parallel and offset relative to each other and the connection interfaces (128; 228; 130,230) are arranged such that when the working channel (110; 210) and the lead cable (116; 216) are connected to the handle (114; 214) the working channel (110; 210) extends from the housing (126; 226) in the same direction relative to the housing as the lead cable (116; 216). Also disclosed is a handle system and an ablation system.

摘要： A microwave ablation probe (100; 200; 300; 400; 500). The microwave ablation probe comprising a dipole antenna (106; 206; 306; 406; 506) arranged to emit microwave radiation to heat surrounding tissue; and a feed cable arranged to supply electromagnetic energy to the dipole antenna, the feed cable comprising a coaxial cable having an inner conductor (108; 208; 308; 408; 508), an outer conductor (110; 210; 310; 410; 510) and a dielectric (112; 212; 312; 412; 512) therebetween. The dipole antenna (106; 206; 306; 406; 506) comprises a first antenna section (106a; 206a; 306a; 406a; 506a) forming a first pole of the dipole antenna and a second antenna section (106b; 206b; 306b; 406b; 506b) forming a second pole of the dipole antenna. The first antenna section (106a; 206a; 306a; 406a; 506a) comprises one or more antenna elements (116a-i; 216a-i; 316a-i; 416a-h; 516a-h) each formed integrally with the outer conductor (110; 210; 310; 410; 510) and comprising an outwardly extending portion (117a) extending away from a longitudinal axis of the feeding cable and bending back over an insulator (118; 318; 418; 518) to form an overlapping portion (117b) extending proximally along the length of the feeding cable. The first antenna section (106a; 206a; 306a; 406a; 506a) further comprises an antenna insulator (118; 318; 418; 518) between the overlapping portion of each of the one or more antenna elements and the part of the outer conductor which they overlap.
