Patent number: 6472228Abstract: This invention relates to novel tracers and their synthesis and use in an immunoassay for the detection of controlled drugs such as amphetamine (APM), methamphetamine (MAPM) and their derivatives, in a biological or aqueous sample. In particular, this invention provides methods for synthesizing novel tracers in which a non-controlled substance is both the starting material in tracer synthesis and the binding site on the resulting novel tracer for the antibody, thereby eliminating the necessity of using controlled substances as starting materials. In addition, the novel tracers of the present invention can be used as an analyte analog in an immunoassay, such as a continuous flow displacement immunoassay. It was unexpectedly discovered that the novel tracers of the present invention substantially improve the performance of the continuous flow displacement immunoassay as compared with conventionally designed tracers.Type: GrantFiled: December 4, 2000Date of Patent: October 29, 2002Assignee: Lifepoint, Inc.Inventors: Guohong Wang, Thomas Foley

Publication number: 20020142484Abstract: In this disclosure, novel caanabinol-based tracers suitable for use in immunoassays that detect cannabinoids in a biological sample are disclosed. These cannabinol-based tracers are particularly useful in a continuous flow displacement immunoassay. The disclosure also describes the processes for synthesizing the novel tracers, and the application of these tracers in fluorescence immunoassays for detecting and quantifying cannabinoids in biological samples.Type: ApplicationFiled: March 12, 2001Publication date: October 3, 2002Applicant: LifePoint, Inc.Inventors: Guohong Wang, Thomas Foley, Connie Chang, Greg Liang, Albert Avila

Patent number: 6217509Abstract: A device (10) is provided which includes an elongated cannula (20) having a first inner diameter (DI) and an outer diameter (DO) sized for percutaneous introduction into a patient. The cannula (20) defines a working channel (25) between its ends (21, 22) which has a second diameter (D2) equal to the diameter (DI) of the cannula sized for receiving a tool therethrough. An elongated viewing element (50) is engageable to the cannula (20) adjacent the working channel (25), preferably by a fixture (30, 170). The fixture (30, 170) includes a housing/body (31, 171) attachable to the proximal end (22) of the cannula (20). The housing (31) defines an optics bore (60, 180) to support a viewing element (50) for translation and rotation relative to the cannula (20) so that the longitudinal axis of the optics bore (60, 180) will translate parallel to and rotate about the longitudinal axis of the working channel (25).Type: GrantFiled: January 20, 1999Date of Patent: April 17, 2001Assignee: SDGI Holdings, Inc.Inventors: Kevin Thomas Foley, Maurice Mell Smith, John B.

Patent number: 6162170Abstract: A method for percutaneous surgery on the spine of a patient under direct visualization is performed through a single cannula having a predetermined length. The length is determined by measuring a distance from the lamina of a spinal vertebra to the skin of the patient, determining a first portion of the length to be less than the measured distance, and determining a second portion of the length to be about one fourth (1/4) the length of the first portion. The first portion is the length of the cannula to be introduced into the patient and the second portion extends external to the patient. This length is preferably 5.5 to 7.0 times greater than the transverse dimension of the cannula. Such dimensions for the cannula permits the longitudinal axis of a tool to be angled between 5 degrees and 8 degrees with respect to the longitudinal axis of the cannula.Type: GrantFiled: January 20, 1999Date of Patent: December 19, 2000Assignee: SDGI Holdings, Inc.Inventors: Kevin Thomas Foley, Maurice Mell Smith, John B.
