Patents by Inventor Mitchell S. Felder

Mitchell S. Felder has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5962306
    Abstract: A method of determining the presence or absence of a nonparaffinophilic microorganism in a specimen taken from a patient includes providing a receptacle containing an aqueous solution that does not contain a carbon source and inoculating the aqueous solution with the specimen. A slide having bound thereto a carbon source is placed into the receptacle. By analyzing the slide after exposure to the specimen, the presence or absence of a nonparaffinophilic microorganism in the specimen can be determined. An associated apparatus is also disclosed.

  • Patent number: 5882919
    Abstract: A method of determining the presence or absence of a nonparaffinophilic microorganism in a specimen taken from a patient includes providing a receptacle containing an aqueous solution and inoculating the aqueous solution with the specimen. A slide coated with a carbon source is placed into the receptacle. By analyzing the slide after exposure to the specimen, the presence or absence of a nonparaffinophilic microorganism in the specimen can be determined. An associated apparatus is also disclosed.

  • Patent number: 5882920
    Abstract: A method of determining the presence of a paraffinophilic microorganism in a specimen taken from a patient. The method includes providing a receptacle containing an aqueous solution and adjusting the solution to mimic the in vivo clinical conditions of the patient. The method then further includes inoculating the solution with the specimen and then placing in the receptacle a paraffin coated slide to bait the paraffinophilic microorganism. The slide is then analyzed after exposure to the specimen to determine the presence or absence of the paraffinophilic microorganism. An associated apparatus is also disclosed.

  • Patent number: 5804406
    Abstract: A method of determining the sensitivity of at least one paraffinophilic microorganism from a specimen obtained from a patient to different antimicrobial agents and predetermined quantities thereof includes providing at least one receptacle containing an aqueous solution and adjusting the solution to mimic the in vivo clinical conditions of the patient. The method then includes inoculating the solution with the specimen and then placing into the receptacle (i) a paraffin coated slide to bait the at least one paraffinophilic microorganism and (ii) a predetermined quantity of an antimicrobial agent to be tested. The slide is then observed for paraffinophilic microorganism growth or lack thereof to determine whether the predetermined quantity of the antimicrobial agent is effective in inhibiting growth of the paraffinophilic microorganisms on the slide. An associated apparatus is also provided.

  • Patent number: 5801009
    Abstract: An apparatus for determining sensitivity of at least one paraffinophilic microorganism from a specimen obtained from a patient to different antimicrobial agents and predetermined quantities thereof. The apparatus includes a receptacle adapted to contain an aqueous solution, an amount of antimicrobial agent to be tested and the specimen. The aqueous solution is adjusted to mimic the in vivo clinical conditions of the patient. The apparatus further includes a paraffin coated slide adapted to being placed in the receptacle.

  • Patent number: 5726030
    Abstract: A method of automatically testing the sensitivity of a paraffinophilic microorganism to different antimicrobial agents and concentrations thereof includes a plurality of receptacles each containing an amount of liquid medium, an antimicrobial agent to be tested and the microorganism to be tested. A paraffin containing slide is placed in each receptacle after which incubation is effected. A light scatter sensor is employed to automatically and sequentially monitor the extent of microorganism growth on the slides and the growth on each slide is employed to determine which antimicrobial agent and which concentration is effective to resist growth of the paraffinophilic microorganism. The slides are moved sequentially in operative relationship with the light scatter sensor while resisting rotational movement of the slides. Positive and negative control slides are preferably employed as is a computer in receiving and processing the results of the slide testing. Related apparatus is disclosed.
