Anti-Kink Coils for Synthetic Vascular Grafts

Cornell University Biofoundry Lab and Anova Biomedical Inc.

Situation

  • Develop manufacturing technology and preliminary models for a novel anti-kink coil designed to increase patency of synthetic vascular grafts produced by Anova Biomedical Inc. and Dr. Yadong Wang

  • Optimize pre-soruced equipment such as plastic extruders to create an automated, well-regulated method for producing multiple coils

Outcomes/ Constributions

  • Design and standardized a PET anti-kink coil system for synthetic vascular grafts, leveraging FEA-guided design optimization to meet ANSI 7198-2001 requirements

  • Developed an automated, custom manufacturing workflow by integrating a motorized linear stage, mandrel spinner, and extruder to create a repeatable, software-controlled process

  • Successfully fabricated and validated 12 anti-kink coils across multiple design variants, successfully characterizing kink resistance and mechanical strength

  • Provided +20 pages of extensive documentation in a design report outlining performance metrics, usability performance in accordance with ANSI 7198-2001, and ANSYS Fluent reports on extruder head flow
