  • Detection of Blood Flow Using Emitted Light Absorption
    Publication number: 20080214943
    Abstract: Perfused tissue is illuminated and light passing through the tissue or reflected from it is detected to produce an electrical signal. Amplitude pulses corresponding to the subject's heart beat are detected in the electrical signal and the areas of these pulses are calculated to produce blood flow values indicative of the blood volume pumped by the heart. The blood flow values may be used alone or in combination with other measured cardiac parameters to evaluate cardiac function.

  • Apparatus and method of holding and manipulating small ultrasound transducers
    Patent number: 6485425
    Abstract: An apparatus and method for holding and manipulating a miniaturized ultrasound transducer includes a flexible member, a retaining member, and a control member. The miniaturized ultrasound transducer is mounted on the flexible member proximate a distal end of the flexible member. The retaining member retains the flexible member proximate the distal end of the flexible member. The control member is coupled to the retaining member and is operable to move the retained flexible member and ultrasound transducer to optimize ultrasound visualization.
