Segmented Drivers for Bifurcation Implant Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for placing implants at vascular bifurcations are complex, leading to unreliable and less precise positioning due to their large size and multiple constituent elements, which complicates surgical interventions and increases morbidity.
Innovation Solution
A method and assembly using two separate launchers with atraumatic tips and sliding sheaths allow for simple, precise, and reliable connection of primary and secondary implants at bifurcations, enabling individual manipulation and reduced size, thereby simplifying surgical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single complex launcher system with multiple constituent elements is used to place implants at bifurcations, then the system can deliver multiple stents and guides, but the device size increases and maneuverability decreases
Solution Approach 1:
The patent divides the implant delivery system into separate launchers for the main duct and secondary conduits. Each launcher is independently manageable, allowing precise control of each implant's deployment position and timing without the maneuverability constraints of a single integrated system.
2Adaptability or versatility
If a single launcher is used to position guides and deliver stents in bifurcation ducts, then the system integrates multiple functions, but the dimensional bulk increases unfavorably
Solution Approach 1:
The patent separates the launcher system into multiple smaller launchers, each dedicated to specific ducts. This segmentation reduces the volume of each individual launcher while maintaining the overall functional capability to deliver implants and position guides in bifurcation structures.
3Ease of operation
If any displacement of a stent is allowed in a single launcher system, then the stent can be repositioned, but this necessarily induces displacement on other stents
Solution Approach 1:
The patent employs separate launchers for each stent, allowing independent manipulation and repositioning of each implant without affecting the position of other stents. This segmentation enables precise positioning control for each stent while maintaining the ability to reposition if needed.
4Adaptability or versatility
If a complex system with multiple constituent elements is used for implant placement, then comprehensive coverage of bifurcation ducts is achieved, but the assembly complexity increases
Solution Approach 1:
The patent divides the comprehensive implant delivery system into multiple simpler, specialized launchers. Each launcher is designed for specific ducts and implant types, reducing the complexity of individual components while collectively achieving comprehensive coverage of the bifurcation vascular structure.

AI summary
The invention relates to a set of drivers for the insertion and connection of implants in conduits exhibiting a bifurcation, a main driver having an internal sheath provided with an atraumatic tip and an axial hole, an external sheath, a main implant disposed between the sheaths, the external sheath being provided with a groove along a part of its length, the internal sheath having a lateral hole facing said groove, said main implant having a window aligned with the lateral hole, the main driver having an extractible complementary sheath, a first end of which passes through the lateral hole, the window and the groove, a secondary driver having an internal secondary sheath provided with a secondary atraumatic tip which has a secondary axial hole, an external secondary sheath, a secondary implant disposed between the secondary internal and external sheaths, a main guide intended to be fitted in the axial hole in order to guide the main driver, a secondary guide passing through the bifurcation in order to be fitted in the complementary sheath in order to position the main driver and/or in order to guide the secondary driver.
