  • Publication number: 20090082620
    Abstract: Suction-assisted tissue-engaging devices, systems, and methods are disclosed that can be employed through minimal surgical incisions to engage tissue during a medical procedure through application of suction to the tissue through a suction member applied to the tissue. A shaft is introduced into a body cavity through a first incision, and a suction head is attached to the shaft via a second incision. The suction head is applied against the tissue by manipulation of the shaft and suction is applied to engage the tissue while the medical procedure is performed through the second incision. A system coupled to the shaft and a fixed reference point stabilizes the shaft and suction head. When the medical procedure is completed, suction is discontinued, the suction head is detached from the shaft and withdrawn from the body cavity through the second incision, and the shaft is retracted through the first incision.

  • Publication number: 20080167669
    Abstract: Embodiments of the invention provide a vessel tensioning handle and method of placing tension on a section of a vessel being harvested. The handle can include a housing, a bobbin assembly, a vessel tensioning tape, and a tensioning device member. The tensioning device member can be coupled to a cannula that is coupled to the vessel. The method can include using the vessel tensioning tape to place tension on the section of the vessel as the cutting device is advanced over the vessel.

  • Publication number: 20080161841
    Abstract: Embodiments of the invention provide a cutting device and method of vessel harvesting. The cutting device can include at least one tubular member, a cutting element, and a centering member. The cutting device can include at least one tubular member with a flexible section and a cutting element. The method of vessel harvesting can include spacing a cutting element of the cutting device from the vessel as the cutting element is advanced over the vessel.

  • Publication number: 20080161843
    Abstract: Embodiments of the invention provide a vessel support system and a method of vessel harvesting. The system can include a cutting device, a catheter adapted to be inserted into a section of the vessel in order to support the vessel as the cutting device is advanced over the vessel, and a cannula adapted to be coupled to the vessel and adapted to receive the catheter as the catheter is inserted into the section of the vessel. The method can include orienting a cutting device coaxially with the cannula and the catheter and advancing the cutting device over the cannula, the catheter, and the section of the vessel in order to core out the section of the vessel and a portion of the surrounding tissue.

  • Patent number: 7338434
    Abstract: This invention provides a heart positioning device, method and system for positioning, manipulating, holding, grasping, immobilizing and/or stabilizing a heart. The heart positioning device may include a suction head and a shaft with a means for remotely changing the position of the head from a first position axially aligned with the shaft to a second, unaligned position and a sleeve slideably positioned on the shaft and sized to receive the suction head in a compressed condition.
