  • Publication number: 20240198080
    Abstract: A blood flow pump device includes a centrifugal pump having a single ball-and-cup hybrid magnetic/blood immersed bearing-supported shrouded impeller driven by a magnetically coupled motor drive. The device further includes a housing, an impeller, and a shroud, thus forming a pump chamber. The impeller is a shrouded impeller having extended blades from a hub of the impeller and the shroud. The system and method employ a blood flow pump device having a housing with a blood inlet and a blood outlet, the housing defining a fluid pathway between the inlet and the outlet, and the housing containing an impeller comprising a base, a base lid, two blades, and a shroud, with the housing positioned on a motor. A controller communicates with the motor and controls rotational speed of the impeller in response to the blood flow through the blood outlet.

  • Publication number: 20100124732
    Abstract: System and methods of detecting and measuring periodontal disease comprising filling a periodontal pocket with a fluid capable of propagating sound waves, transmitting a sound wave into the periodontal pocket, sensing the return sound wave from the periodontal pocket, and determining the depth of the pocket by measuring the time it takes the at least one transmitted sound wave to traverse the periodontal pocket and return. A peak discrimination analysis algorithm is also provided.

  • Publication number: 20080014181
    Abstract: The present invention provides automated devices for use in supporting various cell therapies and tissue engineering methods. The present invention provides an automated cell separation apparatus capable of separating cells from a tissue sample for use in cell therapies and/or tissue engineering. The cell separation apparatus can be used in combination with complementary devices such as cell collection device and/or a sodding apparatus to support various therapies. The automated apparatus includes media and tissue dissociating chemical reservoirs, filters, a cell separator and a perfusion flow loop through a graft chamber which supports a graft substrate or other endovascular device. The present invention further provides methods for using the tissue grafts and cell samples prepared by the devices described herein in a multitude of therapies including revascularization, regeneration and reconstruction of tissues and organs, as well as treatment and prevention of diseases.
