Biological Construct Delivery System with Slotted Cone Passer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic procedures for delivering biological constructs to targeted treatment sites within a patient body often face challenges with inaccurate or difficult placement of these constructs.
Innovation Solution
A biological construct delivery system that includes a passer or grasper with a gripping pad, allowing for the release and re-grasp of the construct for improved handling and positioning. The system uses a slotted cone to roll and advance the construct through a cannula to a desired surgical site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional surgical procedures are used for delivering biological constructs, then delivery capability is achieved, but procedural complexity and invasiveness increase
Solution Approach 1:
The biological construct is nested within a cone-shaped delivery device, which itself is inserted through a cannula. The passer instrument further nests within this arrangement to manipulate the construct. This nested configuration enables minimally invasive endoscopic delivery while maintaining full functionality, avoiding the need for complex open surgical procedures
2Manufacturing precision
If the biological construct is advanced through the slotted cone, then delivery to target site is achieved, but control and repositioning capability are reduced
Solution Approach 1:
The passer instrument features dynamic, movable arms that can open and close to grasp and release the biological construct. This dynamic mechanism allows the operator to grasp the construct for accurate delivery through the cone, then release it for repositioning if needed, providing both precision and flexibility during the procedure
Solution Approach 2:
The passer acts as an intermediary instrument between the operator and the biological construct. It provides a mechanical interface with graspable arms that can securely hold the construct during delivery, then release it for positioning, enabling precise control while maintaining repositioning capability
3Ease of operation
If the passer arms securely grasp the construct, then handling control is improved, but the ability to release and reposition is reduced
Solution Approach 1:
The passer arms are designed with dynamic movement capability, allowing them to transition between open and closed states. When closed, they provide secure grasping for handling control; when opened, they release the construct for repositioning or re-grabbing, providing both control and adaptability

AI summary
A delivery system for biological constructs to targeted treatment sites within a patient body. The delivery system includes a passer or grasper that supports a construct or patch on the end of the grasper between a gripping pad. The passer includes forceps or arms that releasably contain the construct between the arm and the gripper pad. The passer advances the construct through a slotted cone that rolls up the construct as it is advanced through a cone and then exits the slotted cone via an insertion tip that passes the implant or construct through a cannula to a desired surgical site.
