Transit Scientific, LLC

Transit Scientific, LLC manufactures minimally invasive vascular intervention devices focused on peripheral vasculature and dialysis access applications. The company's primary product platform is the XO Score® Sheath Platform, an FDA 510(k) and CE Mark cleared device designed for use with percutaneous transluminal angioplasty (PTA) balloons to facilitate dilation and vessel wall apposition in treating stenotic lesions across multiple vascular territories. Indicated applications include iliac, femoral, ilio-femoral, popliteal, infra-popliteal, and renal arteries, as well as obstructive lesions in native or synthetic arteriovenous dialysis fistulae. The company also offers the XO Cross® Catheter Platform, similarly FDA 510(k) and CE Mark cleared, designed to guide and support guidewires during peripheral vascular access, enable wire exchanges, and serve as a delivery conduit for saline solutions or diagnostic contrast agents. The XO Cath microcatheter line extends the portfolio for controlled and selective infusion of diagnostic, embolic, or therapeutic materials into peripheral vessels, with demonstrated clinical use in transradial embolic delivery procedures. All products are cleared for peripheral vascular intervention but explicitly contraindicated for coronary and neuro-vascular applications. Transit Scientific positions itself within the interventional cardiology and peripheral vascular device sector, targeting interventionalists and vascular surgeons managing stenotic disease and dialysis access complications.
