Enhanced Vasculature Obstruction Removal System
Legal Citation
Summary of the Inventive Concept
A novel vasculature obstruction removal system featuring improved components and methods to securely remove obstructions, reducing the risk of dislodgement and potential complications.
Background and Problem Solved
The original patent for vasculature obstruction removal systems has limitations, including the risk of obstruction dislodgement during removal, which can lead to stroke or heart attack. The new inventive concept addresses this issue by introducing enhanced components and methods that ensure secure removal of obstructions.
Detailed Description of the Inventive Concept
The enhanced vasculature obstruction removal system comprises a guide catheter, a delivery tool with a distal end, and an expandable member with a tapered shape or textured surface to facilitate secure removal of the obstruction. The system may also include a sensor to detect the presence of the obstruction and automatically deploy the expandable member. The method of removal involves deploying the expandable member proximate to the obstruction and using it to prevent dislodgement during removal. The expandable member is designed to conform to the shape of the vasculature, ensuring a secure grip on the obstruction.
Novelty and Inventive Step
The new inventive concept introduces novel components and methods that improve the security and efficiency of vasculature obstruction removal. The tapered shape or textured surface of the expandable member, the sensor-activated deployment, and the conforming design of the expandable member to the vasculature shape are all new and non-obvious features that distinguish the enhanced system from the original patent.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept may include different materials or geometries for the expandable member, adjustable sensor sensitivity, or integration with imaging technologies to enhance visualization during removal. Variations may also include different delivery tool configurations or guide catheter designs to accommodate various vasculature sizes and shapes.
Potential Commercial Applications and Market
The enhanced vasculature obstruction removal system has significant commercial potential in the medical device industry, particularly in the fields of cardiology and neurology. The system's improved safety and efficiency features can reduce healthcare costs and improve patient outcomes, making it an attractive solution for hospitals and medical centers.

Section 103 Obviousness Analysis (PHOSITA)
Field of Art
Medical device engineering, specifically interventional vascular obstruction removal technologies, requiring expertise in catheter design, medical device mechanics, and minimally invasive surgical techniques
Person of Ordinary Skill (PHOSITA) Profile
A biomedical engineer or medical device designer with advanced degree, 3-5 years experience in interventional medical device development, familiar with vascular intervention techniques and device design principles
Obviousness Rationale
A PHOSITA would recognize that the PTD's variations represent predictable engineering modifications to the source patent's core obstruction removal system. The proposed enhancements like tapered expandable members, textured surfaces, and sensor-based deployment are logical extensions of existing medical device design principles addressing known challenges in obstruction removal. These variations represent routine problem-solving within the established technological framework of the source patent.
