Enhanced Dual Lumen Catheter System for Ultrasound-Guided Medical Procedures

An improved dual lumen catheter system for ultrasound-guided medical procedures, offering enhanced visualization capabilities, easier imaging probe insertion, and increased stability during medical device insertion.

The original patent disclosed a dual lumen catheter for ultrasound visualization and sampling of peripheral lung tumors, but it had limitations in terms of range of motion, diagnostic capabilities, and ease of use. The new inventive concept addresses these limitations by introducing improvements to the lumen geometry, material selection, and medical device insertion mechanisms.

The enhanced dual lumen catheter system comprises a catheter with an improved lumen geometry, featuring a tapered entrance to the first lumen for easier imaging probe insertion. The second lumen has a reinforced wall to enhance stability during medical device insertion. The system also includes a novel lumen configuration with a flexible membrane partially enclosing the first lumen to reduce friction during imaging probe insertion, and a textured inner surface in the second lumen to improve medical device traction. Additionally, the catheter assembly may include an integrated optical fiber in the first lumen for transmitting light to illuminate the surrounding tissue, and a reduced inner diameter in the second lumen to accommodate smaller medical devices. A detachable imaging probe and a medical device introducer can be part of the system, allowing for reuse of the imaging probe and minimizing environmental impact.

The new claims introduce novel features such as the tapered lumen entrance, reinforced lumen walls, flexible membrane, textured inner surface, integrated optical fiber, and detachable imaging probe, which are not present in the original patent. These features provide a non-obvious improvement over the existing technology, enhancing the overall performance and usability of the dual lumen catheter system.

Alternative embodiments of the inventive concept could include varying the lumen geometry, material selection, and medical device insertion mechanisms to accommodate different medical procedures and applications. For example, the catheter could be designed for use in cardiovascular or neurovascular procedures, or adapted for use with different types of imaging probes or medical devices.

The enhanced dual lumen catheter system has significant commercial potential in the medical device industry, particularly in the fields of pulmonology, cardiology, and neurology. The system's improved performance and usability could lead to increased adoption and market share, with potential applications in hospitals, clinics, and outpatient settings.
