AI Technical Summary

Benefits of technology

Enables safe and precise energy delivery to hard-to-reach tissue locations during surgical procedures by reducing unwanted heat transfer and allowing for flexible deployment of the ablation probe.

Problems solved by technology

During certain procedures, it can be difficult for the surgeon to deploy an ablation probe, e.g., between closely spaced boundaries of tissue structures, to reach the location of the ablation site.
Currently available microwave ablation devices may not be suitable for use during open surgical procedures when the surgeon is trying to ablate a lesion that is not easily accessed via a midline incision.
A cable assembly connecting the ablation probe to a generator may come into contact with a patient and may facilitate potentially unwanted heat transfer.

Abstract

An energy-delivery device suitable for delivery of energy to tissue includes an antenna assembly, a chamber defined about the antenna assembly, and a cable having a proximal end suitable for connection to an electrosurgical energy source. The energy-delivery device also includes a flexible, fluid-cooled shaft coupled in fluid communication with the chamber. The flexible, fluid-cooled shaft is configured to contain a length of the cable therein and adapted to remove heat along the length of the cable during delivery of energy to the antenna assembly.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application claiming the benefit of and priority to U.S. application Ser. No. 12 / 985,155, filed on Jan. 5, 2011, the entire contents of which being incorporated by reference herein.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to electrosurgical devices suitable for use in tissue ablation applications and, more particularly, to energy-delivery devices with a flexible, fluid-cooled shaft, inflow / outflow junctions suitable for use with the same, and systems including the same.[0004]2. Discussion of Related Art[0005]Treatment of certain diseases requires the destruction of malignant tissue growths, e.g., tumors. Electromagnetic radiation can be used to heat and destroy tumor cells. Treatment may involve inserting ablation probes into tissues where cancerous tumors have been identified. Once the probes are positioned, electromagnetic energy is passed through the probes into surroundi...
