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. 11,857,191.

Summary of the Inventive Concept

An improved surgical anchor device for anchoring to the mucous membrane of the inner wall of the intestine, featuring a temperature-controlled anchor element with radial elasticity property, enabling real-time adjustment of the radial diameter for optimal anchoring and reduced tissue damage.

Background and Problem Solved

The original patent (Method of chirurgical treatment using a surgical anchor device) has limitations in terms of anchor stability and tissue damage. The new inventive concept addresses these limitations by introducing a temperature-controlled anchor element with radial elasticity property, allowing for controlled radial expansion and contraction based on temperature changes.

Detailed Description of the Inventive Concept

The enhanced surgical anchor device comprises a temperature-controlled anchor element made of a shape memory alloy material. This material allows for controlled radial expansion and contraction based on temperature changes. The anchor element is equipped with a temperature sensor and a control unit, enabling real-time monitoring and adjustment of the radial diameter. The device also features an integrated sensor for monitoring the pressure exerted on the mucous membrane, providing real-time feedback to adjust the radial diameter for optimal anchoring. The guidewire used for deployment is equipped with a temperature sensor to monitor the temperature of the anchor device during deployment.

Novelty and Inventive Step

The new inventive concept introduces a temperature-controlled anchor element with radial elasticity property, which is not present in the original patent. This feature enables real-time adjustment of the radial diameter, reducing tissue damage and improving anchor stability. The integration of a pressure sensor and a control unit for real-time feedback and adjustment is also a novel aspect of the inventive concept.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different shape memory alloy materials, varying the design of the anchor element, or incorporating additional sensors for monitoring other parameters such as pH or oxygen levels. Variations could also include adapting the device for use in other parts of the body or for different medical procedures.

Potential Commercial Applications and Market

The enhanced surgical anchor device has significant commercial potential in the medical device industry, particularly in the areas of gastrointestinal surgery and endoscopy. The device's ability to reduce tissue damage and improve anchor stability could lead to improved patient outcomes, reduced recovery time, and increased adoption in hospitals and clinics.
