Patent application numberDescriptionPublished
20080304074OPTICAL CATHETER CONFIGURATIONS COMBINING RAMAN SPECTROSCOPY WITH OPTICAL FIBER-BASED LOW COHERENCE REFLECTOMETRY - The present invention provides apparatuses and methods for sample analysis, such as tissue analysis, that integrate high wavenumber (HW) Raman spectroscopy for chemical composition analysis and optical coherence tomography (OCT) to provide depth and morphological information. The invention also provides side-viewing optical probes that are based on a single double clad optical fiber for performing the combined HW Raman spectroscopy and OCT. Intravascular catheter embodiments and related vascular diagnostic methods are also provided.12-11-2008
20090231578MULTI-CHANNEL FIBER OPTIC SPECTROSCOPY SYSTEMS EMPLOYING INTEGRATED OPTICS MODULES - The invention provides unitary optics modules that integrate several light management functions for performing optical spectroscopy, such as Raman spectroscopy, and optical spectroscopy systems that include one or more of the unitary optics modules. Methods of using the modules and systems are also provided.09-17-2009
20100113906HYBRID BASKET CATHETERS - The invention provides hybrid basket-type intravascular catheter probes designed to optimize blood vessel wall contact or close proximity while traversing tortuous curves. Related diagnostic systems and methods are also provided.05-06-2010
20100315632OPTICAL APPARATUS FOR COMBINED HIGH WAVENUMBER RAMAN SPECTROSCOPY AND SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY - The present invention provides apparatuses and methods for sample analysis, such as tissue analysis, that integrate high wavenumber (HW) Raman spectroscopy for chemical composition analysis and spectral-domain optical coherence tomography (SD-OCT) to provide depth and morphological information. Intravascular catheter embodiments and related vascular diagnostic methods are also provided.12-16-2010

Willam E. Brennan, Iii, Richmond, TX US

Patent application numberDescriptionPublished
20090260798ACTIVE MUD VALVE SYSTEM - A downhole tool pumping apparatus comprising a body and an active valve block. The body comprises a cavity housing a reciprocating piston defining first and second chambers within the cavity. The active valve block comprises a plurality of active valves, wherein the plurality of active valves includes a first active valve fluidly connected to the first chamber of the body, the plurality of active valves includes a second active valve fluidly connected to the second chamber of the body, and each of the plurality of active valves is configured to be actively actuated between open and closed positions.10-22-2009

Patent application numberDescriptionPublished
20100170682INFLATABLE PACKER ASSEMBLY - Conventional formation evaluation with dual inflatable packers includes the steps of pressurizing the packers so as to isolate an annular portion of the borehole wall, collecting one or more samples of formation fluid via the isolated portion of the borehole wall, and depressurizing the packers so as to permit movement of the mandrel within the borehole. A sampling method and apparatus that utilize one or more of the following to advantage is provided: restricting deformation of the packers during inflation using an annular bracing assembly; actively retracting the packers using ambient borehole pressure; and substantially centralizing the mandrel intermediate the packers so as to resist buckling of the mandrel.07-08-2010
