Title: Core drill bit with extended matrix height
Inventor: RUPP MICHAEL
IPC: E21B10/02
Filed: 2007-12-14
Abstract: Core drill bits with extended matrix heights are described. The core drill bits have a series of slots or openings that are not located at the tip of the cutting portion and are therefore enclosed in the body of the matrix. The slots may be staggered and/or stepped throughout the matrix. As the matrix of the drill bit erodes through normal use, the fluid/debris notches at the tip of the bit are eliminated. As the erosion progresses, the slots become exposed and then they function at the proximal face of the bit as fluid/debris ways. This configuration allows the matrix height to be extended and lengthened without substantially reducing the structural integrity of the drill bit. With an extended matrix height, the drill bit can last longer and require less tripping in and out of the borehole to replace the drill bit.

Abstract: A method of detecting a fluorescence signal emitted by fluorophores bound to particles confined in a particle trap, includes an objective lens having a focal plane, which is normally the focal plane for incident collimated light. The particle trap is typically located in the focal plane, and a beam of excitation light is directed via the objective lens onto the confined particles in the trap. The excitation light is in the form of a divergent beam coming to focus at a plane displaced from the focal plane. The divergent beam has a spot diameter at the focal plane determined by the divergence of the beam. The fluorescent light emitted by the fluorophores is detected with a confocal detector.

Abstract: An apparatus for sealing a passage through tissue includes an elongate shaft and a cylindrical plug disposed on a distal end of the shaft, the plug including a helical thread on its outer surface. Intestinal submucosa may be secured to the plus, e.g., in a cavity in its distal end, that may be delivered into the passage. Alternatively, the plug may be formed from a bioabsorbable material and may be released from the shaft within the passage. The plug is threaded into the passage, thereby engaging the tissue to seal the passage. The shaft is rotated until it engages a blood vessel within the tissue while monitoring blood flow through the vessel. The shaft is rotated to thread the plug into the passage until blood flow ceases through the vessel, whereupon rotation of the shaft is reversed to back the plug until blood flow through the vessel resumes.

The in vitro method comprises preparing a suspension of microbeads in a liquid suspension medium, loading the suspension of microbeads with beta 2GPI proteins in a buffer either by coupling in a passive manner in a suspension medium, or using a chemical bonding protocol, contacting the microbeads with the fluid medium in a container in a condition suitable for a fixation of bacteria on the proteins without the presence of oxidizing metal ions, separating the prepared microbeads from the suspension medium by centrifugation, evacuating the suspension medium from the container to obtain a residue with a high concentration of bacteria, and detecting, quantifying and/or identifying the bacterial residue. The microbeads are bounded by an external surface constituted by a solid polymer material able to bind proteins. The microbeads constituting the residue are washed and then contacted with a culture medium for bacterial multiplication and incubation in culture medium for a duration and at a suitable temperature. The fluid medium is sheep blood culture medium. After obtaining high concentration bacterial residue, the microbead suspension is placed in a tripticase soja broth, and then the broth is placed on the sheep blood culture medium. The bacteria is identified by gram staining and/or subculturing on a selective medium. The bacteria is quantified by reading optical density, adenosine triphosphate (ATP) meter or by polymerase chain reaction (PCR) lysate. The solid material constituting the outer surface of microbeads is a plastic material, an elastomer, and a material optionally bearing reactive groups grafted on the outer surface of the microbeads to ensure a chemical bonding with the proteins. The microbeads have a spherical form and an average diameter of 1-100000 nm, and a core made of magnetic material particles to allow their separation with respect to the suspension medium by a magnetic field. The protein microbeads is loaded in the liquid suspension medium, which contains 10 -> 6>to 100 mg of proteins and a concentration of 10 -> 5>to 10 mu g/mu l by stirring the suspension for 15-60 minutes at a temperature of 30-45[deg] C.
