AngioJet^® Ultra - Reducing Size and Complexity

Possis had a proven technology for the removal of blood clots in the brain. Unfortunately the control console that drove the surgical headpiece left much to be desired for the scrub nurse to operate and the circulating nurse to support. The operating room has been called the most expensive real estate in the world and the existing system was much too large, not to mention the interface was difficult to use requiring multiple layers of “help” tools.

From the Inside Out

Some of the major mechanical innovations included creating a structure from low cost aluminum extrusions that housed the computer and pump assemblies. In addition to low capital cost, this structural system also acted as a thermal chimney to draw heat out of the system. Insight also redesigned the pumping assembly to be fully automated in terms of loading and priming of the pump set, which was key in the reduction of set-up steps from thirteen down to just four.

A Muti-Layered Challenge

The first generation user interface was less than ideal. The initial device at launch was difficult to use so an “explanation” card was sent out by the sales reps to be attached to the front of the drive unit to help explain some of the difficult steps in the interaction. In response, the interface team developed an icon based sequential interaction architecture that was simple to use and quick to set up. Hospitals are rapidly turning to the AngioJet® Ultra system for its simple and fast setup process, sleeker design, lighter weight, and handling improvements that make it significantly easier to maneuver than the previous generation product.
