20090189067COMPONENTS FOR REDUCING BACKGROUND NOISE IN A MASS SPECTROMETER - Novel components reduce background noise caused by secondary ions generated by metastable entity bombardment in a mass spectrometric system. Layered structures for exit electrodes and deflector plates confine secondary ions in a local low-energy well, preventing them from entering the detector.07-30-2009
20110056311Method of Scanning a Sample Plate Surface Mask in an Area Adjacent to a Conductive Area Using Matrix-Assisted Laser Desorption and Ionization Mass Spectrometry - A method of scanning a sample plate surface mask in an area adjacent to a conductive area using mass spectrometry is disclosed. The method comprises the steps of providing a sample plate including a mask applied with a rough surface to the electrically conductive surface to produce a sample site comprising a central portion formed from the electrically conductive surface and a marginal portion of the mask, preparing an analyte comprising mixing a biomolecule with an organic solvent, an aqueous solution, and a matrix selected from the group of α-cyano-4-hydroxycinnamic acid and 3,5-dimethoxy-4-hydroxycinnamic acid; applying the analyte to the sample site; forming at least one crystal of the analyte in an area on the mask adjacent to the conductive area, and scanning the area on the mask adjacent to the conductive area with a laser beam.03-10-2011

20100012598Device and Method for Separating Components of a Fluid Sample - A device and method is provided for separating heavier and lighter fractions of a fluid sample. The device includes a plurality of constituents comprising a container and a composite element in the container. The composite element is a separator comprising at least two components and more particularly an elastic portion and a plug member. A fluid sample is delivered to the container and the device is subjected to centrifugation whereby the centrifugal load causes the elastic portion of the separator to deform so that the separator migrates into the fluid sample and stabilizes between the heavier and lighter fractions of the fluid sample. The elastic portion of the separator will resiliently return to its initial configuration upon termination of the centrifugal load such that the elastic portion sealingly engages the container and separates the heavier and lighter fractions of the fluid sample.01-21-2010
20110172686Device For Engaging Tissue Having a Preexisting Opening - A system for performing an end-to-side vascular anastomosis. including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple. A second aspect of the invention includes an anastomotic fitting, having an inner flange over which the graft vessel is everted and an outer flange which contacts the exterior surface of the target vessel. A tailored amount of compression applied by the inner and outer flanges grips the target vessel wall and creates a leak-proof seal between the graft vessel and the target vessel. A third aspect of the invention has a flange to which the graft vessel attaches, by everting the graft vessel over the flange, and a plurality of staple-like members which attach the flange and the everted end of the graft vessel to the wall of the target vessel to form the anastomosis07-14-2011

20120029536ENDOSCOPIC SUTURING DEVICE - An endoscopic suturing device that can be employed to suture tissue using endoscopic techniques to place one or more stitches in tissue during a single intubation of an endoscope. The suturing device may include a suturing capsule with a suction chamber that is configured to capture tissue that is to be sutured. A needle is movable along a pathway across the suction chamber to penetrate and place stitches in the captured tissue. A catch is located distal to the suction chamber to receive and retain the suture during a stitching sequence. The catch may be movable along the needle pathway and configured to release the suture when the catch moves a predetermined distance along the pathway. The catch may be configured so that a predetermined amount of force is required to move the catch the predetermined distance required to release the suture.02-02-2012
