Tissue Repair Device Sequential Implant Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tissue repair instruments require multiple actuation components to sequentially deploy implants, which can be cumbersome and inefficient, and often use larger implants with higher profiles that are not easily deployable with a single device.
Innovation Solution
A tissue repair device with a linear actuator and push mechanism that allows for the sequential deployment of multiple pairs of implants with pre-positioned sutures, using a single device, enabling distal and proximal movement to engage discrete positions and deploy implants with smaller diameters and anti-rotation features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple actuation components are used to sequentially deploy implants, then implant deployment capability is improved, but device complexity increases
Solution Approach 1:
The push mechanism is divided into multiple discrete push members (first push member, second push member, third push member) that can independently deploy different implants. Each push member can be selectively actuated to deploy a specific implant, enabling sequential deployment of multiple implants through a single actuation component that moves in discrete steps along the longitudinal axis.
Solution Approach 2:
The push mechanism employs a dynamic actuation system where a single actuation component moves distally and proximally in discrete increments along the longitudinal axis of the base. This dynamic movement allows the same actuation component to engage different push members at different positions, enabling sequential implant deployment without requiring multiple separate actuation components.
2Strength
If larger implants with higher profiles are used, then implant strength is improved, but ease of deployment with single device deteriorates
Solution Approach 1:
Multiple implants of varying sizes and profiles are nested within the single needle and push mechanism assembly. The needle has sufficient internal diameter to accommodate multiple implants with different cross-sectional dimensions, and the push mechanism can selectively push out each implant from the distal end, enabling deployment of larger implants that would otherwise be difficult to manage with a single device.
Solution Approach 2:
The invention transitions from managing multiple separate devices in three-dimensional space to containing multiple implants within a single linear needle assembly. By organizing implants along the longitudinal dimension of the needle rather than requiring separate devices, the system simplifies deployment while maintaining the ability to deploy implants with larger cross-sectional dimensions.
3Productivity
If multiple implants are deployed sequentially from same device, then productivity is improved, but device complexity increases
Solution Approach 1:
The single actuation component serves multiple functions by moving to different discrete positions along the longitudinal axis to engage different push members. This universal actuation mechanism replaces what would traditionally require multiple separate actuation components, enabling sequential deployment of multiple implants while maintaining a relatively simple device architecture.
Solution Approach 2:
Multiple push members are pre-positioned within the needle assembly in a ready-to-deploy configuration before the procedure begins. Each push member is pre-loaded with its corresponding implant, allowing the operator to simply actuate the single actuation component in discrete steps to sequentially deploy implants without requiring complex real-time manipulation or reconfiguration during the procedure.

AI summary
Embodiments of the invention include a tissue repair system and related components and associated methods that provide for suturing of tissue using three or more suture anchoring implants, including multiple pairs of connected implants in some embodiments, all of which may be deployed from a single device. Some embodiments achieve this by employing a push mechanism capable of being activated to advance the push mechanism incrementally to discrete positions within the device and deploy implants one at a time from the device.
