An ablation probe (1; 100; 200), comprising: an applicator (2; 102; 202) arranged to apply radiation to heat surrounding tissue; a feeding cable (4; 104; 204) arranged to supply electromagnetic energy to the applicator. The feeding cable comprises a distal portion (2a, 202a) and a proximal portion (2b; 202b). The distal portion of the feeding cable has a distal cross sectional size and the proximal portion of the feeding cable has a proximal cross sectional size, wherein the distal cross sectional size is less that the proximal cross sectional size. The ablation probe further comprises a connector (24; 224) arranged to mechanically and electrically couple the distal portion (2a, 202a) of the feeding cable (2; 202) to the proximal portion (2b; 202b) of the feeding cable (2; 202). The connector comprises a joining member (12) comprising a proximal end (12b) shaped to receive an end of the proximal portion (2b; 2b) of the feeding cable and a distal end (12a) shaped to receive an end of the distal portion (2a; 202a) of the feeding cable.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

Unitary endoscopic vessel harvesting devices are disclosed. In some embodiments, such devices may comprise an elongated body having a proximal end and a distal end. A conical tip may be disposed at the distal end of the elongated body. In addition, the surgical instrument may include one or more surgical instruments moveable in a longitudinal direction along an axis substantially parallel to a central longitudinal axis of the cannula from a retracted position proximally of a distal end of the tip to an advanced position toward the distal end of the tip to seal and cut a blood vessel.

An elongate applicator body for use with a microwave applicator, the elongate applicator body including a tip portion, a first dielectric isolator having a first length, a first shunt, a second dielectric isolator having a second length, a second shunt, a third dielectric isolator having a third length, a microwave transmission line and an outer sleeve.

A flexible instrument comprises an antenna having a distal tip portion, a proximal base, and an antenna body therebetween. The antenna body comprises a patterned cylindrical structure having a proximal end coupled to the proximal base and a distal end coupled to the distal tip portion. The flexible instrument is configured to generate a radiation pattern from the antenna to ablate tissue.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that may include a microwave ablation probe. The microwave ablation probe may include a feedline having an inner conductor, an outer conductor and a dielectric; and an antenna including a helical arm, the helical arm being electrically connected to the outer conductor of the feedline at a junction point, and a linear arm, the linear arm being electrically connected to the inner conductor of the feedline.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, ultra-MIS techniques.
