Patent number: 6113580Abstract: The female vaginal douche with cervical shield is a unique device with a wide range of health implications. The device is unique because there is no existing device available that offers the ability to cleanse the vaginal mucosa without allowing a forceful flow of fluid, debris, and bacteria (both commensal and pathogenic), into the uterine cervix. At present, when vaginal douching takes place, there is no barrier in place to protect or shield the cervix from this potentially harmful practice. By combining the vaginal douche applicator with an attached cervical shield, access to the uterine cervix will be limited. The limitation theoretically prevents microorganisms from entering the upper female genital tract. Shielding the cervix during vaginal douching has the potential to prevent serious pelvic infections including pelvic inflammatory disease, tuboovarian abscess, endometritis, as well as female factor infertility and potentially life threatening ectopic pregnancy.Type: GrantFiled: August 27, 1998Date of Patent: September 5, 2000Assignee: American Maternity Products, Inc.Inventor: Frank Dolisi

Patent number: 5391159Abstract: An improved gastrostomy tube is a flexible tube having on one inner end thereof an improved energy absorbent internal retaining member which provides for less patient trauma during emplacement and subsequent percutaneous removal, while almost entirely avoiding either separation of the internal retaining member, i.e., the bumper, or its acute displacement. The energy absorbing internal retaining member has a hollow body portion with two resiliently reversible physical forms or shapes, toroidal-like, and, goblet-like connected to a foreshortened hollow axial stem portion that is attached to or integrally made with the inward end of the flexible tube. The internal retaining member is made in the toroidal-like form. During intentional removal, when under pressure against the stomach mucosa, the internal retaining member snaps into the unrolled, goblet-like shape and pulls smoothly out through the stoma tract.Type: GrantFiled: February 4, 1994Date of Patent: February 21, 1995Inventors: William H.

Patent number: 5265606Abstract: A probe carrying sensor means at its distal tip is supported centrally within a blood vessel by an introducer catheter. The introducer catheter includes a percutaneously insertable shaft which is configured to engage and be supported by the inner luminal surface of the blood vessel. The distal tip of the catheter shaft is disposed along a central axis of the catheter such that when the catheter is disposed in the blood vessel, the distal tip will be disposed substantially along that axis and substantially in the center of the blood vessel lumen. The probe passed through the catheter thus will emerge from the distal outlet orifice of the catheter into the blood vessel at the central axis of the blood vessel.Type: GrantFiled: February 25, 1993Date of Patent: November 30, 1993Assignee: C.

Patent number: 5181907Abstract: A method for removing fatty tissue from a patient includes the steps of inserting an aspirating cannula into the fatty tissue of the body, removing the fatty tissue in the vicinity of an internal layer of the patient's skin and traumatizing the skin adjacent to the area from which fatty tissue is removed. The method is generally carried out by means of an improved aspirating cannula which includes a longitudinally extending tubular member, an opening at one end thereof and a plurality of integrally formed projecting members surrounding the openings. The projecting members are relatively narrow and thin and extend radially outwardly and longitudinally. An annular member which is angularly disposed with respect to the longitudinally projecting member and of similar width and thickness connects the longitudinal members and is effective in breaking down fat tissue without cutting blood vessels or nerves during reciprocal movements of the cannula.Type: GrantFiled: October 31, 1991Date of Patent: January 26, 1993Inventor: Hilton Becker
