Neurovascular Structures

Neurovascular Structures
When designing neurovascular products, maximizing performance while minimizing the deliverable profile is essential. Understanding the desired delivery method and the materials required to engineer an effective precision-controlled component are crucial to the design & development process. Secant Medical combines advanced materials with biomedical textile forming technologies to enable the minimally invasive expansion and compaction of critical neurovascular devices.
 
Nitinol Knit

A variety of materials can be used to achieve the specialized characteristics for devices used in ischemic stroke prevention and aneurysm repair. Metals such as nitinol and cobalt chromium are selected for their stiffness, precision and shape memory, while platinum provides radiopacity.
 
Our cross-functional team develops biomedical structures that have definitive benefits to neurovascular devices, including shape-transforming capabilities, controlled porosity, and low-profile fabrics as thin as
40-50 μm.

  • Situation

    The client was facing an issue getting prototypes for benchtop evaluation and animal studies in a timely manner. A standard three to five-week lead time would have caused them to miss scheduled trials and seriously jeopardize their project.

  • Challenge

    Benchtop evaluation and animal studies for a new biodegradable neurovascular device were set to begin in just a few weeks. There was just one problem, though: the device prototype had yet to be completed. The original development partner was facing resource constraints and could no longer meet the client’s needs.

    At this stage, the device developer could not adhere to the standard three- to five-week lead time typically required for one round of prototyping. The pressure was on—missing the animal study deadline would seriously jeopardize the project.

  • Action
  • Results

    After fabricating several iterations of the device prototype, Secant Group finalized the design in a record time of two days. The accelerated prototyping process saved the client an estimated six months of development time and financial resources and ensured that the device entered animal studies on time.
