Patent number: 10792018Abstract: Methods are disclosed for non-invasively obtaining fetal cells from a pregnant female. The methods include placing an absorbent medium in an interlabial or intravaginal space or adjacent to the perineum at the vaginal opening of the pregnant female, and collecting vaginal fluid comprising cells in the absorbent medium while the absorbent medium is interlabial or intravaginal space or adjacent to the perineum at the vaginal opening. The absorbent medium is removed and cells are isolated from the absorbent medium to obtain the fetal cells. The fetal cells can be, for example, somatic cells, embroyic stem cells, fetal stem cells or trophoblast cells.Type: GrantFiled: August 13, 2018Date of Patent: October 6, 2020Assignee: Preprogen LLCInventors: William H.

Patent number: 8398606Abstract: A multi-layered, absorbent perineal pad is disclosed that has a generally ovate cross-section. In disclosed embodiments, the pad has an absorbent outer layer, antimicrobial intermediate layer, and absorbent inner layer. At least two opposing edges of the pad are sealed to one another so that the absorbent inner layer encloses an internal cavity within the pad. The pad may be used to absorb liquids from perineal structures (such as vaginal or anal liquids) or administer agents to perineal structures. Liquids that are absorbed in the pad can be subjected to diagnostic assays.Type: GrantFiled: February 28, 2008Date of Patent: March 19, 2013Assignee: QuantrRx Biomedical CorporationInventor: William H.

Patent number: 8062277Abstract: A method is disclosed for absorbing anal leakage, such as fecal material, blood or flatulence. The method includes positioning an intergluteal absorbent pad external to the anal orifice of a subject such that the pad is retained between the buttocks, and any discharge from the anus is absorbed by the absorbent material of the pad. The pad can have a variety of shapes, including major and minor portions that are portions of spheres or ellipsoids, or which are elongated and have cross-sections that are circular or ellipsoid. The smaller minor portion of the pad is positioned against the anal orifice to minimize pressure exerted in this sensitive area, while the larger major portion is retained in the less sensitive intergluteal space. Insertion and retention of the pad adjacent to the anus helps alleviate symptoms of the hemorrhoids, absorbs leakage, and can also be used as a reservoir to administer medication.Type: GrantFiled: April 3, 2009Date of Patent: November 22, 2011Inventor: William H. Fleming

Publication number: 20110166432Abstract: A diagnostic agent is delivered intravaginally or to the interlabial space by positioning an interlabial device, such as an absorbent pad, between the labia. The pad is retained between the labia to deliver an active agent, or allow a reaction with a diagnostic agent. Alternatively, the pad is applied after the diagnostic agent is administered, to help reduce discomfort to the subject, or loss of the diagnostic agent. The active agent may be carried by the pad itself, or in an intravaginal extension of the pad, or separately in a suppository or other dosage form. In particular examples, the pad has a smaller minor portion superimposed on a larger major portion, and the smaller minor portion is inserted as a leading edge between the labia of the subject to facilitate interlabial insertion. In another example, the pad is placed interlabially after insertion of an agent.Type: ApplicationFiled: January 12, 2011Publication date: July 7, 2011Inventor: William H. Fleming

Patent number: 7488606Abstract: A device for collecting oral liquids includes a lateral flow chromatography strip having a collection member. The collection member is separated from the remainder of the chromatography strip by a liquid impermeable removable barrier which prevents liquid in the collection member from entering the chromatography strip. Once adequate oral liquid has been collected (as indicated by a sample sufficiency indicator), the barrier is removed to allow oral liquids to flow through the strip. The liquids interact with binding partners in the strip to provide test results, such as an indication that an analyte of interest is present in the liquid. The strip may be contained in a housing with an access opening through which the removable barrier may be manipulated, and windows through which test results may be viewed. This device avoids reflux of reagents from the strip into the mouth of a test subject during use.Type: GrantFiled: August 19, 2005Date of Patent: February 10, 2009Assignee: QuantRX Biomedical CorporationInventors: William H. Fleming, Timothy P. Hyatt, Dudley B. Thomas

Patent number: 6821513Abstract: A method is provided for enhancing hematopoiesis. The method includes transplanting at least a therapeutically effective portion of an isolated vascular tissue into a subject, wherein the vascular tissue enhances hematopoiesis. A method is also provided for detecting an agent that affects hematopoiesis. The method includes transplanting a portion of an isolated vascular tissue into a subject, wherein the portion of the isolated vascular tissue is sufficient to enhance hematopoiesis. The vascular tissue is treated with an agent, and hematopoiesis is detected in the subject. Hematopoiesis in the subject is compared with hematopoietic in a control. A change in hematopoiesis in the subject as compared to the control indicatives that the agent affects hematopoiesis. A method is provided for isolating a hematopoiesis growth factor using the method of the invention. In addition, a method is provided for isolating a hematopoietic stem cell using the method of the invention.Type: GrantFiled: December 20, 2001Date of Patent: November 23, 2004Assignee: Oregon Health & Science UniversityInventor: William H.

Publication number: 20020115976Abstract: A method is disclosed for administering an agent (for example delivering a drug or diagnostic agent) intravaginally or to the interlabial space by positioning an interlabial device, such as an absorbent pad, between the labia. The pad is retained between the labia for a sufficient period of time to deliver an active agent, or allow a reaction with a diagnostic agent. Alternatively, the pad is applied after medication is administered, for example intravaginally or labially or perilabially, to help reduce discomfort to the subject, or loss of medication. The active agent may be carried by the pad itself, or in an intravaginal extension of the pad, or separately in a suppository or other dosage form. In particular examples, the pad has a smaller minor portion superimposed on a larger major portion, and the smaller minor portion is inserted as a leading edge between the labia of the subject to facilitate interlabial insertion.Type: ApplicationFiled: February 16, 2001Publication date: August 22, 2002Inventor: William H.
