An apparatus for assisting in a vascular procedure includes an obturator that interfaces with a surface of tissue, the obturator including a shaft and a groove that can guide one or more tips of a medical device into a targeted region. In more specific embodiments, the targeted region is an aortic hole. The obturator can include a knob that stabilizes the medical device laterally on a surface of the targeted region. The obturator can also include a flange element that extends beyond the knob onto an outside surface of the targeted region. The knob can include a chamfer feature that can provide room for the tips of the medical device to enter the targeted region at an angle without bumping into the knob. In still other embodiments, the tips are sharp needle tips of the medical device and the groove is a V-shaped groove.

A device to be used in a cardiovascular environment, comprising an expandable element that is coupled to a rod and that includes a compressed state and an expanded state. The expandable element is operable to be positioned within a wall of an organ while the expandable element is in the compressed state. The expandable element is further operable to be deployed once it is within the organ such that it is in the expanded state. The device further includes a cutter element operable to make a circular incision at the wall of the organ. The expandable element creates a resistive force when it is pulled against the wall while in the expanded state such that an interface is created for making the incision. The device includes a stop-grip mechanism that maintains the resistive force at the interface. One embodiment features the expandable element being umbrella shaped.

An apparatus is provided in one example embodiment and includes a body section having an upper surface, a lower surface, and an inner edge circumferentially arranged around at least a portion of an open area. The apparatus also includes a tool extending from the body section into the open area for holding a graft vessel. The lower surface of the body section opposes a receiving vessel when the tool is positioned to transfer the graft vessel to the receiving vessel, such that the graft vessel is axially accessible through the open area to be attached to the receiving vessel. In more specific embodiments, the body section has first and second opposing ends defining a gap sized to permit the vessel to pass through.
