Sequential Prosthesis Deployment Device for Tissue Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for repairing tissue imperfections, such as rotator cuff tears, are complex and laborious, requiring multiple steps and tools like sutures and anchors, which can be time-consuming and limit the number of surgeons capable of performing the operation.
Innovation Solution
A deployment device that houses multiple prostheses and uses a driving assembly with a driving pin and tube to apply force, allowing for sequential implantation of prostheses in a controlled manner, simplifying the repair process by reducing the number of steps and tools needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional suture and anchor methods are used to repair tissue imperfections, then the repair can be performed with simple tools, but the procedure becomes complex and laborious requiring multiple steps and tools
Solution Approach 1:
The patent combines multiple prostheses (anchors and sutures) into a single integrated deployment device. The device houses multiple individual prostheses that can be sequentially deployed through one incision site, merging what would traditionally require separate insertion steps and multiple tools into a single unified system.
Solution Approach 2:
The deployment device serves multiple functions: it stores multiple prostheses, provides sequential deployment capability, guides implantation through tissue, and enables controlled force application. This multi-functional device replaces the need for multiple separate tools that would traditionally be required for anchor and suture insertion.
2Reliability
If multiple prostheses are implanted using traditional methods, then adequate repair can be achieved, but the surgical time increases and accessibility is limited
Solution Approach 1:
Multiple prostheses are pre-loaded and prepared within the deployment device before the surgical procedure begins. The sutures are pre-threaded through the anchors, and the entire assembly is ready for sequential deployment, eliminating the need to prepare each component separately during surgery.
Solution Approach 2:
Multiple individual prostheses are nested within the single deployment device housing. Each prosthesis is contained within the device in a compact arrangement, allowing multiple implants to be delivered through a single access point without requiring separate incisions or extensive surgical exposure.
3Ease of operation
If a single prosthesis is deployed at a time using conventional devices, then controlled implantation is achieved, but the number of incisions and surgical steps increases
Solution Approach 1:
The deployment device enables continuous implantation action by sequentially deploying multiple prostheses through a single incision without requiring withdrawal or repositioning of the device between implants. The surgeon can deploy anchors and sutures in sequence through the same access point, maintaining continuous useful action.
Solution Approach 2:
While maintaining a single unified device, the implantation process is segmented into controlled sequential steps where individual prostheses are deployed one at a time. Each prosthesis can be independently controlled and positioned, allowing precise placement while avoiding the need for multiple separate surgical interventions.

AI summary
A deployment device for a tissue repair system includes a front delivery assembly that is detachable from a base assembly of the deployment device. The front delivery assembly includes at least one prosthesis and at least one driven assembly that actuates the at least one prosthesis. The base assembly includes a driving assembly that may engage the at least one driven assembly of the at least one prosthesis. The front delivery assembly can be rotated so that the position of a prosthesis in the front delivery assembly is moved in and out of alignment with the driving assembly. A kit of parts may be provided that includes a base assembly as well as two or more detachable front delivery assemblies.
