Abstract:
An apparatus for assisting in a vascular procedure includes an obturator operable to be mounted on a medical device to guide the medical device into a targeted region, whereby the obturator is substantially blunt such that it exhibits a snag-resistant property. In alternative embodiments, the apparatus includes an interface element operable to be used in conjunction with the obturator and to engage an interface of the targeted region such that pressure is maintained within the targeted region. The interface element includes a convex portion that operates to seat the interface element at a selected location. The interface element is substantially transparent and includes a magnification element that magnifies materials underlying the interface element. In other embodiments, the apparatus includes a tray operable to provide a mold for forming the obturator, which may include a gas, water, sugar, clotted blood, a gelatinous material, a protein, a saline solution, or dry-ice.
