Patent number: 7428904Abstract: The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or a copper alloy. The device is anchored within the fallopian tube by imposing a secondary shape on a resilient structure, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. The resilient structure is then restrained by the walls of the fallopian tube, imposing anchoring forces as it tries to resume the secondary shape.Type: GrantFiled: May 14, 2004Date of Patent: September 30, 2008Assignee: Alien Technology CorporationInventors: Julian Nikolchev, Dai Ton, Amy Thurmond

Patent number: 7080647Abstract: A T-shaped intrauterine device includes a longitudinal branch constituting a body of the T, to the upper higher of which is connected a transversal stem constituting the arms of the T. The body of the T is made up of a fiber that releases an active substance. The fiber constituting the body of the T presents a transverse channel on its upper part. The arms are inserted by force into the channel to form two equal arms on opposite side of the body. The stem forming the arms presents a curved form so that a wedging force exercised by the body on the stem is such that the latter is usually held in the channel in a position where the arms are oriented downwards of the body, while it is allowed to pivot in the channel until the arms are oriented upwards of the body under the effect of constraint exercised on the arms at the time of the extraction from the womb by an extraction wire of the device.Type: GrantFiled: February 12, 2003Date of Patent: July 25, 2006Inventor: Dirk Wildemeersch

Patent number: 7047975Abstract: Employing the known “tensegrity” principle, a female condom is configured such that when the condom is inserted into a woman's vagina, the woman's introitus acts on a proximal section of an elongated pouch extending between internal and external biasing members (e.g., rings) of the condom. Inward compressive forces exerted by the introitus on the inner ring of the condom cause the inner ring to be pushed distally within the vaginal canal, and the proximal pouch section to become a tension member pulling against the external ring. This causes a “tenting” of the proximal pouch section against the introitus. The resulting interaction of compression and tensile forces (a tensegrity effect) serves to provide the condom with a high degree of internal and external stability, including resistance to twisting and slippage.Type: GrantFiled: August 3, 2001Date of Patent: May 23, 2006Assignee: PathInventors: Glenn D. Austin, Lisa Tam

Patent number: 6526980Abstract: An cervical drug delivery apparatus having an absorbent cylindrical structure with a cervical cap attached to one end. One or more therapeutic agents are applied to the internal surface of the cervical cap. The cervical drug delivery apparatus is housed within an applicator and inserted into a patient's vagina. Upon deployment of the cervical drug delivery apparatus, the cervical cap is automatically positioned over the patient's cervix providing for the direct application of the therapeutic agents on the patient's cervix. Alternative features of the cervical drug delivery apparatus include, a break-away cylindrical structure, a collapsible support structure for the cervical cap, an inflatable means for supporting the cervical cap, and the ability of the cylindrical structure and/or the cervical cap to contain one or more therapeutic agents that can be delivered by outside means.Type: GrantFiled: August 25, 2000Date of Patent: March 4, 2003Assignee: West Virginia UniversityInventors: Timothy S.

Patent number: 6526979Abstract: The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or a copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has a helical outer surface, together with a portion of the resilient structure which is biased to form a bent secondary shape, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. Optionally, permanent sterilization is effected by passing a current through the resilient structure to the tubal walls.Type: GrantFiled: June 12, 2000Date of Patent: March 4, 2003Assignee: Conceptus, Inc.Inventors: Julian N. Nikolchev, Dai T. Ton, Ashish Khera, Donnell W. Gurskis, Steven Bacich

Publication number: 20030005937Abstract: The present invention reveals a device, a kit and a method for simultaneously delivering and distributing at least one beneficial agent to both the cervical and vaginal lumen sides of a vagina. The device is made of a flexible circular rim and a flexible dome. The device can exist in either a relaxed state or in a compressed state. In the compressed state, pouches are formed for carrying and delivering the beneficial agent to both the cervical and vaginal lumen sides of the vagina.Type: ApplicationFiled: August 15, 2002Publication date: January 9, 2003Inventors: Thomas R. Moench, Richard A. Cone, Kevin J. Whaley

Publication number: 20020166558Abstract: This is a birth control device that prevents pregnancy for extended periods of time with the same degree of certainty as permanent sterilization: however, this sterilization is easily reversible when childbearing is desired. This device is implanted through a medical procedure. It consists of two tubes that may be positioned either in a closed or open position and held there by a clip to either prevent or allow fertilization of the egg. Accessing this device to change from open to closed or vice versa requires a medical procedure.Type: ApplicationFiled: May 11, 2001Publication date: November 14, 2002Inventors: Oliver J.

Patent number: 6418930Abstract: An incontinence pessary device for use within a vaginal vault of a woman, the incontinence pessary device comprising a resilient main support body, at least two resilient lateral support bodies, and a suburethral support body. The resilient main support body has a primary plane of orientation that will correspond to the sagittal plane of the woman's pelvis when inserted and be at least responsive to forces oriented along the main plane. The at least two resilient lateral support bodies project from a position on the main support body toward generally opposite sides of the main support body in a secondary plane generally perpendicular to the primary plane. Thus, when inserted, the at least two resilient lateral support bodies provide lateral and additional rotational stabilization, being at least responsive to forces oriented along the secondary plane.Type: GrantFiled: November 14, 2000Date of Patent: July 16, 2002Assignee: Mayo Foundation for Medical Education and ResearchInventor: Robert Stuart Fowler

Publication number: 20020083949Abstract: A female incontinence device and method for placement of an intravaginal device for repositioning and supporting the prolapsed neck of the urinary bladder and realigning the urethra both vertically and laterally to approximate normal anatomical position enable a patient to remain stress-continent. The device includes an open, generally droplet-shaped base coupled with a pair of elongate spaced parallel legs shaped to extend in orthogonal relationship to the plane of the base in a predetermined configuration. Upon installation, the legs provide support for the anterior wall of the vagina and adjacent neck of the urinary bladder at a preconfigured variable distance from the posterior vaginal wall, as well as lateral and vertical alignment and support of the adjacent urethra. Alternatively, the base may be coupled with a single leg having a predetermined configuration which extends orthogonal to the plane of the base and is attached to the base at both ends.Type: ApplicationFiled: January 3, 2001Publication date: July 4, 2002Inventor: Larry W.
