Summary of the Inventive Concept

This inventive concept adapts the biopsy device with an aspiration valve for use in specific, narrow markets or unique operational environments, addressing the limitations of the original patent in these contexts.

Background and Problem Solved

The original biopsy device with an aspiration valve is designed for general medical use, but it lacks features that cater to high-security needs, disaster relief, extreme weather conditions, remote resource-limited areas, or sterile isolated environments. This inventive concept addresses these limitations by providing specialized biopsy devices that meet the unique demands of these specific contexts.

Detailed Description of the Inventive Concept

The inventive concept includes a biopsy device with a tamper-evident aspiration valve and secure, encrypted data storage for high-security environments. For extreme weather conditions, the device incorporates a heating or cooling element to maintain a stable temperature during the biopsy procedure. The device can also be designed as a portable system for disaster relief, complete with a power source and communication module for transmitting biopsy sample information to a remote medical facility. In remote, resource-limited areas, the device can be manually operated using a hand crank or other non-electric means. Additionally, the device can be equipped with a UV-C light source for sterilization in sterile, isolated environments.

Novelty and Inventive Step

The new claims provide a non-obvious solution by adapting the biopsy device with an aspiration valve to specific, narrow markets or unique operational environments, addressing the limitations of the original patent in these contexts. The inventive concept's novelty lies in its specialized features, such as tamper-evident aspiration valves, secure data storage, heating or cooling elements, and UV-C light sources, which are not found in the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of secure data storage, such as biometric authentication or advanced encryption methods. The device could also be designed with modular components, allowing users to customize the device for specific environments. Additionally, the device could be integrated with other medical equipment, such as imaging devices or laboratory analyzers, to provide a more comprehensive medical solution.

Potential Commercial Applications and Market

The inventive concept has commercial potential in various industries, including healthcare, biotechnology, and medical devices. The target markets include high-security facilities, disaster relief organizations, remote medical facilities, and sterile, isolated environments. The device's ability to adapt to specific environments and needs makes it an attractive solution for these industries.
