Rapid-Exchange Monorail Guide Wire for Distal Vessel Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current percutaneous intervention (PCI) procedures require time-consuming and costly methods for delivering guide wires with different characteristics to distal locations in blood vessels, particularly in scenarios involving chronic total occlusions, stent deployment, or catheter exchanges, which are cumbersome and risky.
Innovation Solution
A Buddy Guide Wire (BGW) system using a rapid exchange concept, allowing the delivery of a guide wire over a previously placed wire or catheter, with features like a monorail design and snap-on capabilities to facilitate efficient and rapid guide wire delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional guide wire delivery methods are used, then guide wires can be delivered to distal locations, but the procedure is time-consuming and costly
Solution Approach 1:
The system pre-positions a guide wire in a proximal location with a delivery catheter, preparing everything in advance so that when the catheter is advanced, the guide wire is already in place and ready for immediate use, eliminating the need for time-consuming on-site wire delivery operations
Solution Approach 2:
The delivery catheter acts as an intermediary vehicle that carries the guide wire from the proximal location to the distal target site, enabling rapid transfer without requiring the guide wire to be manually delivered through complex exchange procedures
2Adaptability or versatility
If guide wires with different characteristics are delivered through catheter exchange, then different wire properties can be used, but the process becomes cumbersome and risky
Solution Approach 1:
The system separates the guide wire delivery function from the catheter by using a dedicated delivery catheter that can be independently positioned and exchanged, allowing the guide wire to be pre-loaded and then transferred without requiring complex simultaneous catheter and wire manipulation
Solution Approach 2:
Different guide wires with specific characteristics can be pre-loaded into the delivery catheter in advance, so when the catheter is advanced to the target site, the appropriate wire is already positioned and ready, eliminating the need for complex on-site wire exchange procedures
3Ease of operation
If traditional buddy wire techniques are used, then guide wires can be placed to help straighten curves, but it requires placing multiple wires and is time-consuming
Solution Approach 1:
The guide wire is pre-positioned in the proximal location and pre-formed to the desired configuration before the delivery catheter is advanced, so that when the catheter is positioned, the wire is already in place with the correct shape and orientation, eliminating time-consuming on-site formation and placement procedures
Solution Approach 2:
The delivery catheter serves as an intermediary that carries the pre-formed guide wire to the target site, allowing the wire to be delivered with its desired curvature and configuration already established, rather than requiring time-consuming manipulation and formation procedures at the distal site

AI summary
A rapid exchange guide wire system for rapid delivery of a guide wire to a blood vessel. The system has a main guide wire and rapid a rapid exchange tube attached to the main guide wire near a distal end of the main guide wire. The rapid exchange tube has a lumen which extends in a longitudinal direction and is configured to permit the rapid exchange tube to be reversibly displaceable in the longitudinal direction over a medical device having a cylindrical portion The medical device may be a guide wire, balloon angioplasty catheter, stent delivery catheter, atherectomy catheter, intravascular ultrasound catheter, blood flow measurement wire, optical coherence tomography catheter, or a stent-on-wire catheter.
