  • Patent number: 8047980
    Abstract: A method for treating urinary incontinence includes the steps of inserting into the woman's vagina a first disposable device, removing the first disposable device, and inserting a second disposable device substantially identical to the first disposable device. The disposable devices have a working portion with opposed faces to provide support to an associated urinary system and, optionally, an anchoring portion to maintain the disposable device in place during use. The working portion also has. The working portion also has an insertion equivalent diameter ranging from about 10 to about 25 mm and a use equivalent diameter ranging from about 25 to about 35 mm under an expansion pressure of about 20 to about 150 cm H2O.

  • Publication number: 20110152605
    Abstract: An intravaginal urinary incontinence device has an insertion end and an opposed withdrawal end. The device has a resilient frame including a working portion disposed proximate the withdrawal end and an anchoring portion disposed proximate the insertion end. The working portion has a resilient structure having a plurality of connected elongate elements for providing support to an associated urinary system. The anchoring portion has a plurality of connected elongate elements arranged to expand laterally within a user's vagina. The elongate elements are formed of a high modulus polymer having an elastic modulus of at least 2 or 3 GPa. Additionally, the polymer may have an Initial Stress @ 3% Strain of at least about 30 MPa, an elongation at yield of at least 3%, a Stress Ratio of at least about 0.5, and/or an Aged Stress (t=50 hrs @ 40° C.) @ 3% Strain is greater than about 35 MPa.

  • Publication number: 20110152604
    Abstract: An intravaginal urinary incontinence device has an insertion end and an opposed withdrawal end. The device has a resilient frame including a working portion disposed proximate the withdrawal end and an anchoring portion disposed proximate the insertion end. The working portion has a resilient structure having a plurality of connected elongate elements arranged and configured to define opposed working surfaces for providing support to an associated urinary system. The anchoring portion extends beyond the working portion and has a plurality of connected elongate elements arranged and configured to expand laterally within a user's vagina. The elongate elements are formed of a high modulus polymer having an elongation at yield of at least 3% and an elastic modulus of at least 2 Gpa.
