Solitaire revascularization device

After receiving IRB approval from the University at Buffalo, we retrospectively analyzed the clinical and radiographic data of 45 consecutive patients undergoing me-chanical thrombectomy for acute ischemic stroke at our institution in whom a stroke bundle was used to purchase mechanical thrombectomy devices between December 1, 2018, and February 15, 2019. In the "bundle purchase program," there is a flat fee for the devices used to perform mechanical thrombectomy. Because the devices may be different depending on the thrombectomy strategy (e.g., stent retriever vs aspiration, radial vs femoral access), we developed several versions of the bundle (Table 1). The devices used in the "bundle purchase program" included the Avigo 0.014-inch microwire (Medtronic), Phenom 0.027inch or Marksman 0.027-inch microcatheter (Medtronic), React 0.068-inch aspiration catheter (Medtronic), Cello 8-Fr balloon guide catheter (Medtronic), and Solitaire revascularization device (Medtronic).
We evaluated the charges associated with the devices used to perform mechanical thrombectomy. We then compared the device-related costs of the procedure using the previous "à la carte charging" model (e.g., charging for each device individually) to the bundle cost to calculate a percentage of savings for each case.
