  2. Project Overview LEC • Intended Use: Open Liver Biopsy • Combines 3 Functions • Removal of Tissue • Cauterization • Biopsy Tissue Protection

  3. LEC DEVICE LEC Blades 17 cm 2 cm

  4. Individual Responsibilities LEC • Blade Redesign • Testing Protocol • Design History File Update

  5. Secondary Blade Design LEC • Remove Closed Faces • Facilitate Easy Removal of Tissue Sample • Simplify Fabrication Process • Round Triangular Edges • Wedge Point is difficult to cauterize • Simplify Fabrication by removing joints

  6. Testing Protocol LEC • Preliminary Testing Using CosmosWorks - Examine stresses subjected on device • Discarded Livers from Animal Research Study • Cutting Ability • Cauterization Effectiveness • Cauterization Time • Heat and Current Protection

  7. Testing Protocol (Cont.) LEC • Sterilization Test • -Multiple Autoclave Cleansings • User Survey • Ease of Operation • Comfortableness • Comparison to Previous Biopsy Technique

  8. Design History File LEC • Revise and Update DHF to ensure proper representation of the LEC tool

  9. Upcoming Milestones LEC • Functional Computer Prototype – 2 weeks • Submit for Fabrication – 2 weeks • Full Testing Completed – 4/7/05 • Revised Design History File – 4/7/05
