Abstract: Disclosed are systems and methods of lymphatic specimen tracking, visualization, and lymph node drainage pathway determination. An exemplary method includes receiving computed tomographic (CT) image data corresponding to a CT scan, generating a three-dimensional (3D) model of at least a portion of a patient's body based on the CT image data, identifying one or more lymph nodes in the 3D model, performing a registration of the 3D model with one or more physical locations in the patient's body, determining an expected lymph node drainage pathway away from a region of interest through one or more lymph nodes, and displaying the 3D model and the expected lymph node drainage pathway.

Abstract: Computer-assisted surgical systems and methods provide intraoperative playback of and interaction with recorded video images and/or a 3D model while displaying current video images. The methods and related surgical systems involve capturing, by a two-dimensional (2D) or three-dimensional (3D) video camera, current video images and recording the captured video images. A user interface displays the current video images and the recorded video images and/or the 3D model and enables a user to interact with either or both of them.

Abstract: A system and method for supplying microwave energy to tissue for microwave therapy includes an electrosurgical generator having an output for coupling to a surgical instrument. The electrosurgical generator includes a microwave energy source and a controller for controlling the operation of the electrosurgical generator. The surgical instrument, coupled to the electrosurgical generator, includes a microwave antenna for delivering microwave energy from the microwave energy source. The controller of the electrosurgical generator is operable for causing the electrosurgical generator to apply at least two pulses of microwave energy.

Abstract: Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.

Abstract: An antenna guide assembly including a guide body having a proximal end defining at least one proximal entry, a distal end defining at least one distal port, and at least one guide passage extending between the proximal and distal ends. The at least one guide passage is configured to receive at least a portion of an antenna therethrough via the at least one proximal entry such that a distal portion of the antenna extends through and distally from the at least one distal port for insertion into tissue. A locking assembly disposed at the distal end of the guide body is configured to receive the distal portion of the antenna therethrough. The locking assembly is configured to selectively engage the distal portion of the antenna to prevent translation of the antenna within the at least one guide passage.
