  • Kit of alignable tools for preparing an intervertebral site for implanting a prosthetic intervertebral disc
    Publication number: 20110092976
    Abstract: We describe various alignable tools, in particular, trials and chisels, that may be used in preparing an intervertebral site in a spine, the site being suitable for placement of a prosthetic intervertebral disc as a replacement for a natural disc in that spine. We also describe methods of using those tools.

  • Tubing set for blood handling system and methods of use
    Patent number: 7291124
    Abstract: A tubing set for use with a blood handling system is described that decreases the priming volume and surface area of the blood handling circuit, lowering the risk of hemodilution, platelet activation, and hemolysis. The tubing set also reduces the number of manual connections required, and uses quick-disconnect couplings to facilitate connections between the various lines, and between the lines and the arterial and venous cannulae.

  • Convertible extracorporeal blood perfusion systems
    Publication number: 20060089586
    Abstract: A convertible extracorporeal blood perfusion system for receiving venous blood from a patient and for returning oxygenated blood to the patient in a cardiopulmonary bypass procedure including: a closed-loop cardiopulmonary bypass system; and a circuit for converting between the closed-loop cardiopulmonary bypass system and a cardiopulmonary bypass system containing a venous reservoir, the circuit for converting comprising a venous reservoir that can be fluidly connected to a venous line from the patient and that can be fluidly connected to the inlet of a first pump, the first pump being part of the closed-loop cardiopulmonary bypass system, the closed loop cardiopulmonary bypass system comprising a bubble removal device fluidly connected to the inlet of the first pump.
