A device for assisting in a vascular procedure is provided that includes a handle and one or more legs that are operable to move in response to a force being applied to the handle. The legs are operable to extend and to contract in order to manipulate a conduit. In a more particular embodiment, the device can be used in conjunction with a stand operable to receive the conduit such that the conduit can be removed from the stand by the device. The stand may include one or more graduations that indicate the size of the conduit once it is positioned on the stand.

System and method for attaching a vein, an artery, or a tube in a vascular environment

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.

System and method for attaching a vessel in a vascular environment

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.

System and method for providing an obturator for enhanced directional capabilities in a vascular environment

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.

System, device, and method for providing access in a cardiovascular environment

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.

A system for moving a large object is provided that includes one or more wheels in contact with a ground surface and two pedals coupled to at least one wheel such that a downward force on at least one of the pedals by an operator seated on the system causes the wheels to move in a forward direction. The system further includes a gearing element that includes a gearbox that translates the downward force to the wheels. The system also includes a loading element that receives at least a portion of the large object such that it can be transported when the wheels move in the forward direction, where the large object weighs at least 300 pounds. In more specific embodiments, the system includes a steering component that includes one of the wheels, where the steering component allows a direction of the system to be guided by the operator.

System and method for moving large objects

A suture retainer for use with a surgical instrument comprises a slot defined in the surgical instrument, the slot having a bottom and lateral slot ends. A retainer block comprises a bottom and lateral block ends. The lateral block ends and the lateral slot ends are configured to matingly engage to define a v-shaped gap adjacent a lateral slot end near a mouth of the slot.
