Abstract: A blood pump assembly has a balloon disposed at a distal region and a driveline disposed at a proximal region and is capable of being employed to provide mechanical circulatory support (e.g., counterpulsation). A blood pump support apparatus has a support structure with a head region and a tail region that is removably disposable in the blood pump assembly. When the support structure is disposed in the blood pump assembly, the head region is disposed within the balloon. When the blood pump assembly is implanted in the descending aorta and the support structure is disposed in the blood pump assembly, forces act on the balloon that would cause the balloon to roll or fold upon itself along an angle with respect to the balloon's longitudinal axis. The head region of support structure opposes these forces.

Abstract: A blood pump assembly comprises a balloon defining an elongated inflatable chamber with an opening at the proximal end. The proximal region of the balloon is substantially cylindro-conically shaped, and tapering toward the proximal end of the balloon, the central region of the balloon is substantially cylindrically shaped with a substantially uniform exterior diameter. The distal region of the balloon is substantially cylindro-conically shaped, the distal region of the balloon tapering toward the distal end of the balloon. The length of the distal region of the balloon is greater than approximately 15% of the combined length of the proximal and central regions of the balloon. A driveline may be coupleable to the opening and have a connection element disposed at a proximal end of the driveline. A radio opaque marker may be integrated into the driveline at a distal end of the driveline.

Abstract: A level comprising a level body and a bubble vial mounted on the level body. The bubble vial includes a bubble vial body comprising a clear material and an internal cavity containing a liquid. A top opening in the level body that interrupts at least a portion of a top wall to accommodate the bubble vial. An internal support structure disposed within the tubular configuration of the level body and spanning longitudinally along the level body so as to be disposed on both sides of the top opening to provide structural support to the level body in the vicinity of the top opening. A carrier positioned beneath the bubble vial and between the internal support structure and the bubble vial. The bubble vial body has a length that is less than a length of the top opening in the top wall of the level body.

Abstract: A composite level and a method to manufacture the composite level are provided. A composite level can have three layers of material. A first layer comprises a glass-mat material, a second layer comprises carbon fiber, and a third layer comprises a glass fabric material. A composite level can also have only two layers of material. At least one bubble vial is mounted on the level body. The method to manufacture the carbon fiber composite level comprises a pultrusion process wherein a fiber glass material and carbon fiber are saturated with resin and molded into a final shape.

Abstract: The invention provides a demolition tool that can be used in many ways for the demolition of construction materials or other materials. The demolition tool includes a handle having a head at one end. The head has a longitudinal central plane that bisects the head, a strike contact face, and toothed, stepped grasping jaws that accommodate multiple sizes of lumber or other material. The head may also include a blunt blade edge below the strike contact face for striking and demolishing material. The demolition tool includes a bent end pry bar at a second end of the handle. The bent end pry bar being offset 90 degrees from the longitudinal central plane of the tool head enabling full range of motion without interfering with other tool functions. The demolition tool may comprise a single piece of material and may be softer than tools used to strike it, but harder than materials which it is used to strike.
