Enhanced Implant Delivery System with Improved Performance and Safety Features
Legal Citation
Summary of the Inventive Concept
An advanced implant delivery system that addresses the limitations of the original system, offering improved performance, safety, and efficiency in delivering implant devices to target sites within the body of a patient.
Background and Problem Solved
The original implant delivery system, although effective, has inherent limitations. For instance, the pusher member may experience friction during delivery, and the tether material may not provide optimal tensile strength. The new inventive concept resolves these issues by introducing a non-stick coating on the pusher member, a tether made of a material with improved tensile strength, and additional features such as real-time imaging, variable stiffness, and detachable tips.
Detailed Description of the Inventive Concept
The enhanced implant delivery system comprises a pusher member with an elongated shape and a non-stick coating to reduce friction during delivery. The distal end of the pusher member is connectable to an implant, and a tether connects the pusher member and the implant. The tether is made of a material with improved tensile strength. Additionally, the system features a sensor embedded in the pusher member to detect changes in temperature or pressure indicative of detachment, generating an alert signal to notify a medical professional of potential detachment. The system may also include a built-in ultrasound transducer for real-time imaging, a variable stiffness pusher member to accommodate different anatomical pathways, and a detachable tip to facilitate easy removal of the pusher member after implantation.
Novelty and Inventive Step
The new claims introduce several novel features that distinguish the enhanced implant delivery system from the original patent. These include the non-stick coating, improved tether material, sensor-based detachment detection, real-time imaging, variable stiffness, and detachable tips. These features provide a significant improvement in performance, safety, and efficiency, making the new inventive concept non-obvious and innovative compared to the original patent.
Alternative Embodiments and Variations
Alternative embodiments of the enhanced implant delivery system may include different materials for the pusher member and tether, varying geometries for the pusher member, and alternative sensors or detection methods for implant detachment. The system may also be adapted for use in various medical procedures, such as cardiovascular, neurological, or orthopedic interventions.
Potential Commercial Applications and Market
The enhanced implant delivery system has significant commercial potential in the medical device industry, particularly in the fields of interventional radiology, cardiology, and neurology. The system's improved performance, safety, and efficiency make it an attractive solution for medical professionals and hospitals, offering a competitive advantage in the market.
