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. 11,857,160.

Summary of the Inventive Concept

This inventive concept presents a suite of direct improvements and enhancements to the original luminal structure anchoring devices and methods, focusing on automated deployment, reduced tissue irritation, and improved fluid flow monitoring.

Background and Problem Solved

The original patent described devices and methods for forming an anastomosis between two luminal structures in the body. However, these devices and methods had limitations, such as manual deployment, potential tissue irritation, and lack of real-time fluid flow monitoring. The new inventive concept addresses these limitations by introducing an integrated spring coil component, anti-inflammatory coatings, and fluid flow sensors, enabling faster, safer, and more efficient transluminal interventions.

Detailed Description of the Inventive Concept

The enhanced luminal structure anchoring device features an integrated spring coil component that facilitates automated deployment in minimally invasive procedures. The device is also coated with an anti-inflammatory agent to reduce tissue irritation. Furthermore, the device includes a sensor for monitoring fluid flow through the anastomosis, enabling real-time feedback and improved patient outcomes. The inventive concept also encompasses a system for forming an anastomosis, comprising a delivery catheter and the enhanced luminal structure anchoring device. Additionally, the device's hollow member is coated with a lubricious material to facilitate smooth passage of the penetrating member during deployment.

Novelty and Inventive Step

The new claims introduce several novel and non-obvious features, including the integrated spring coil component, anti-inflammatory coatings, fluid flow sensors, and removable design. These features collectively provide a significant improvement over the original patent, enabling faster, safer, and more efficient transluminal interventions.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the spring coil component's design, material, or pre-biasing mechanism. Additionally, the anti-inflammatory coating could be replaced with other therapeutic agents or modified to target specific tissue types. The fluid flow sensor could also be integrated into the delivery catheter or used in conjunction with other monitoring systems.

Potential Commercial Applications and Market

The enhanced luminal structure anchoring devices and methods have significant commercial potential in the medical device industry, particularly in the areas of endoscopy, endosonography, and transluminal interventions. The target market includes hospitals, clinics, and medical research institutions, with potential applications in gastrointestinal, cardiovascular, and pulmonary medicine.
