    摘要: A positioning anchor is provided for a stent-graft for implantation to treat a damaged body lumen. The positioning anchor is generally tubular surrounding a primary fluid conduit. Arms extend laterally from the generally tubular structure of the anchor surrounding lateral fluid conduits. The form of these arms is preferably custom configured to match a particular patient's luminal geometry. The anchor thus fits within the luminal geometry to remain in a desired fixed position for implantation of the anchor and any stent-graft coupled to the anchor. The anchor is most preferably formed with two walls having a void therebetween which can be filled with fixation media to further secure the anchor at the desired implantation site. A lumen shaper balloon and delivery catheter are also disclosed for proper delivery, expansion and inflation of the positioning anchor and stent-graft elements according to this invention.

    摘要: A system is provided for high volume print-forming of structures made up of multiple separate layers. A support bed is provided which has multiple steps arrayed thereon at different heights. Substrate blocks rest upon each of the steps. A printing process is utilized to print material from which the structures are to be formed down onto the substrate blocks. This printing process prints different layers onto each of the substrate blocks. The substrate blocks then move to a different step on the support bed and the printing process is repeated. Each support block has a partial structure thereon which receives its next successive layer in each printing cycle until the partial structure becomes a completed structure by having each of its layers sequentially printed thereon. Subsystems are provided for moving the substrate blocks upon the support bed and for properly holding and aligning substrate blocks upon the support bed.

    摘要: An improved surgical clip and clip applicator for placing a surgical clip over a target structure. The surgical clip generally has a pair of opposing clamp arms, each having an associated clamping surface, and a connecting portion joining the clamp arms and biasing them to a normally closed position. The surgical clip may be opened and locked into the open position prior to being loaded into a clip applicator or the surgical clip may be opened by a clip applicator itself. The surgical clip and clip applicators require reduced actuation forces and simplified applicator mechanisms.

    摘要: The invention is methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. Pursuant to the invention, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles is effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all. Typically, in separate steps, the surgeon contacts the heart with the stabilizing device, assesses the degree of movement of the anastomosis site, and exerts a force on the stabilizing device such that the contraction of the beating heart causes only minimal excess motion at the surgery site. By fixing the position of the stabilizing device in a configuration where the motion of the beating heart is effectively eliminated, the surgeon is able to stabilize the beating heart for the duration of the procedure. The stabilizing device may be attached to a rigid support or may be attached to a semi-rigid support which is rendered motionless mechanically, chemically, or by human intervention. In certain preferred embodiments, the stabilizing device is affixed to a semi-rigid support which is caused to become rigid, by any of a variety of techniques, such that the position of the stabilizing device becomes fixed by the support, and the heart remains substantially motionless for the duration of the procedure.
