Implantable Lead Connector With Lamella Basket for Stable Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting implantable lead devices within the body, such as cardiac pacemaker leads, are inefficient and prone to incorrect placement due to the need for repeated disconnection and reconnection of alligator clips and plastic sleeves, which can lead to displacement and require cumbersome repositioning, especially during procedures like left bundle branch pacing.
Innovation Solution
A connector with a lamella basket and collet clamping fixtures that securely maintain electrical contact with lead electrodes, allowing for controlled rotation and fixation of the lead without disrupting the connection, even when the electrodes rotate relative to the basket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alligator clips and plastic sleeves are removed to rotate the lead for fixation, then the lead can be properly positioned and fixedated, but the distal end of the lead may be displaced and the procedure becomes cumbersome
Solution Approach 1:
The connector maintains electrical connection and mechanical support for the lead before fixation is performed. The alligator clips are pre-positioned and remain attached throughout the rotation and fixation process, eliminating the need for removal and reattachment.
Solution Approach 2:
The connector serves multiple functions simultaneously: it provides electrical connection via alligator clips, mechanical support during manipulation, and enables rotation for fixation while maintaining continuous monitoring capability.
2Manufacturing precision
If the lead is rotated rapidly and repeatedly for left bundle branch pacing, then deep septal positioning is achieved, but the electrical connection may be disrupted
Solution Approach 1:
The connector provides both mechanical support for rapid rotation and continuous electrical connection through alligator clips that remain attached during the entire manipulation process, including rapid repeated rotations for LBBP.
Solution Approach 2:
The alligator clips are pre-positioned and securely attached to the lead electrodes before the rapid rotation sequence begins, ensuring continuous electrical connection throughout the high-speed manipulation required for deep septal positioning.

AI summary
A connector (1) for electrically connecting a proximal end of a lead device (2) that is implantable within the body of a patient and comprises a lead (3, 5), wherein the connector (1) comprises a lead contact (15, 16) for, directly or indirectly, electrically contacting, at the proximal end of the lead device (2), an electrode (8) of the lead (3, 5). The first lead contact (15, 16) comprises a lamella basket. A lead clamping fixture comprises a collet (20, 27) that can embrace the lead (3, 5) at a proximal end of the lead (3, 5) and has an external taper, and the lead clamping fixture moreover comprises a collet sleeve (21, 28) that has an internal taper for cooperating with the external taper of the collet (20, 27) to secure the collet (20, 27) on the lead (3, 5) by compressing the collet (20, 27) if the collet's (20, 27) external taper is pressed against the collet sleeve's (21, 28) internal taper.
