Patent number: 7479130Abstract: A system and method for autologous normovolemic hemodilution (ANH) are disclosed. The system can include a vacuum canister, which is sized to accept donor bags of a predetermined capacity. The vacuum canister is connected to a vacuum source which applies a suction to the donor bag within the canister. The system can include a canister having a self-generated vacuum, which includes compressible sidewalls that are spring-loaded to provide negative pressure needed to collect blood from a patient without the use of a gravity-induced siphon gradient. Also disclosed are ANH systems and kits that rely on a gravity-induced siphon gradient for blood collection.Type: GrantFiled: December 23, 2005Date of Patent: January 20, 2009Assignee: University Hospitals of Cleveland Case Western Reserve UniversityInventor: James R. Trickett

Patent number: 7072047Abstract: A method of correcting optical coherence tomography (OCT) image data obtained from a layered media sample includes identifying at least one interface from the obtained OCT data and correcting the OCT data for distortion at the at least one interface. The OCT image data can be corrected for extrinsic distortions, such as those caused by scan geometry, as well as, intrinsic distortions, such as those caused by refraction at each interface.Type: GrantFiled: July 14, 2003Date of Patent: July 4, 2006Assignees: Case Western Reserve University, University Hospitals of ClevelandInventors: Volker Westphal, Andrew M.

Patent number: 7061622Abstract: An optical coherence tomography (OCT) system including an interferometer provides illuminating light along a first optical path to a sample and an optical delay line and collects light from the sample along a second optical path remitted at several scattering angles to a detector. In one embodiment, illuminating light is directed along a number of incident light paths through a focusing lens to a sample. The light paths and focusing lens are related to the sample and to both the incident light source and the detector. In another embodiment, a focusing system directs light to a location in the sample. A transmission grating or acousto-optic modulator directs light from the sample at an angle representative of the wavelength of the incident light on the transmission grating or acousto-optic modulator.Type: GrantFiled: August 5, 2002Date of Patent: June 13, 2006Assignees: Case Western Reserve University, University Hospitals of ClevelandInventors: Andrew M.

Patent number: 7006232Abstract: A phase-referenced Doppler optical coherence tomography (OCT) system includes a low-coherence optical radiation source and a reference source co-propagated to a sample arm and a reference arm. The low-coherence and reference optical radiation reflected from the reference and arms is detected by a pair of detectors, yielding OCT and reference interferometric data output signals. The reference interferometric data output signal can be used to correct the OCT interferometric to yield velocity-indicating images that are free from defects due to sample motion and/or interferometer jitter.Type: GrantFiled: April 7, 2003Date of Patent: February 28, 2006Assignees: Case Western Reserve University, University of Hospitals of ClevelandInventors: Andrew M.
