This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,148.

Summary of the Inventive Concept

This inventive concept adapts medical devices with flexible circuit assemblies for sympathetic nerve modulation to operate in specialized, high-stress environments, such as high-altitude, disaster relief, high-security, extreme weather, or remote areas, addressing the limitations of existing devices in these settings.

Background and Problem Solved

Intracorporeal medical devices, like guidewires and catheters, have been developed for various medical uses, including sympathetic nerve modulation. However, these devices are often not designed to withstand extreme environmental conditions, such as temperature fluctuations, high winds, or unauthorized access. This inventive concept solves the problem of adapting sympathetic nerve modulation devices for use in these niche environments.

Detailed Description of the Inventive Concept

The inventive concept comprises a medical device with a catheter shaft, a balloon, and a flexible circuit assembly, where the polymer substrate of the flexible circuit assembly is adapted to withstand extreme temperature fluctuations, is tamper-evident and resistant to unauthorized access, or is designed for prolonged storage and use in areas with limited access to medical facilities. The device may be deployed in a disaster relief setting, used in high-security facilities, or operated in extreme weather conditions, ensuring reliable sympathetic nerve modulation in these environments.

Novelty and Inventive Step

The inventive concept's novelty lies in its adaptation of sympathetic nerve modulation devices for use in specialized, high-stress environments, which is not addressed by the original patent. The inventive step is the recognition of the need for these adaptations and the implementation of design modifications to ensure device reliability and effectiveness in these environments.

Alternative Embodiments and Variations

Alternative embodiments may include using different materials or designs for the flexible circuit assembly, incorporating additional features for environmental monitoring or device security, or developing specialized packaging or storage solutions for the device. Variations may also include adapting the device for use in other niche environments, such as space exploration or search and rescue operations.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of sympathetic nerve modulation, disaster relief, high-security facilities, and extreme weather operations. Target markets may include medical device manufacturers, disaster relief organizations, government agencies, and private companies operating in these environments.
