Microwave Ablation Electrode with Cooling Structures
Summary
The USPTO granted patent US12605203B2 to Mianyang Lide Electronics Co., Ltd. for a microwave ablation electrode featuring dual cooling structures. The non-working end circulation cooling structure allows a refrigerant medium to reach and cool the non-working end and surrounding tissues, with provisions for return flow. The working end liquid injection structure allows refrigerant to reach the working end to cool it and surrounding tissues. The patent includes 6 claims and was filed on May 18, 2023.
What changed
The USPTO issued patent grant US12605203B2 to Mianyang Lide Electronics Co., Ltd. for a microwave ablation electrode design incorporating both a non-working end circulation cooling structure and a working end liquid injection structure. The cooling mechanisms allow a refrigerant medium to circulate through the main needle body to cool both the working end (where microwave energy is released) and the non-working end, as well as surrounding tissues.
For manufacturers and developers of microwave ablation medical devices, this patent establishes intellectual property rights that may constrain product development or licensing strategies. Medical device companies engaged in ablation electrode design should review this patent's claims to assess potential infringement risks or licensing needs with the assignee.

Abstract
A microwave ablation electrode is provided. The microwave ablation electrode mainly comprises a main needle body. A working end of the main needle body can release microwave energy to realize microwave ablation. A non-working end circulation cooling structure and a working end liquid injection structure are arranged on the main needle body, wherein the non-working end circulation cooling structure can allow a refrigerant medium to reach a front end of a non-working end of the main needle body to cool the non-working end of the main needle body and the surrounding tissues, and the non-working end circulation cooling structure can allow the refrigerant medium to flow back. The working end liquid injection structure can allow the refrigerant medium to reach the working end of the main needle body to cool the working end and the surrounding tissues.
