Brief Procedure Introduction

Vein Analysis Syndaver Labs Synthetic Vein Tissue Testing FEA Synthetic Vein Tissue Analysis FEA Vein Environment Modeling Analysis

Prototype Assembly/Construction Progress Proof of Concept

Overview

1) Prepare the Pacemaker Pocket1) Detach Pacemaker Leads

2) Prepare Leads

3) Insert LLD (Lead Locking Device)1) Expand LLD to lock in place

4) Deploy Laser Over Lead and LLD

5) Lase through all Fibrous Tissue

Problem Lies in Fibrous Occlusions

Vein Extraction Procedure

Testing Procedure Lowering tissue onto laser tip (12 french) Reading force tissue exerts on laser on a scale Increase force by lowering tissue until rupture

18 Tests were conducted 6 tests at three different angles were tested Tried to model the angles that may occur during surgery Each test lasted an average of 1 minute and 53 seconds

Syndaver Labs Tissue Testing

COMSOL was the software used

Limits of Software Do not know true material properties of Syndaver tissue Cannot model tearing Cannot model soft tissue

Non-linear Non-homogeneous Transient response

Sythetic Vein FEA

Software Used was SolidWorks Limits of Software

Cannot model tearing Unknown material properties (Poisson’s Ratio) Cannot accurately model vein constraints

Cannot model soft tissue Non-linear Non-homogeneous Transient response

Vein Environment FEA

Design made to minimize cost while preserving durability and usability

Construction was difficult to get coordinated Mind Studios vs. Machine Shop

End Result Proof of Concept Design Recommendations
