  • Patent number: 7241259
    Abstract: A device and method for treating female urinary incontinence is provided. A device in accordance with the invention includes a sheath having a distal portion, a proximal portion, and a lumen extending therebetween. A distal member is elastically hinged to the distal portion of the sheath. A flow control valve unit is disposed within a lumen of the sheath. The distal member may be urged into axial alignment with the sheath, and the device may be inserted into a female urethra. Once the device is inserted sufficiently distally into the female urethra, the distal member will return to a position which is not in axial alignment with the sheath.

  • Patent number: 6070588
    Abstract: A device, system and method for treating female urinary incontinence is provided. A flexible sheath having distally deployed wings and proximal retainer contains a flow control valve unit within. The wings can be tucked into side access holes to reduce the profile of the sheath for insertion distally into a female urethra. Once inserted sufficiently distally into a female urethra, the wings can be deployed by inserting the flow control valve within sufficiently far to force the tucked wings out of the constraining access holes.

  • Patent number: 5599070
    Abstract: A seat (20) includes a frame (22) with a first frame portion (26) supporting a seat bottom (40) and a second frame portion (24) supporting a seat back (42) and attached at two places (28) to the first frame portion to define a reference axis (A). Seat belt webbing (62) carries a tongue (64) and has an end (82) fixed to the first frame portion (24). A retractor (84) is fixed to the frame (22) and another end of the seat belt webbing is operably connected with the retractor. A buckle (80) is fixed to the first frame portion (26) of the seat (20) to receive the tongue (64). A guide (100) extends through the seat back for guiding movement of the seat belt webbing (62) through the seat back (42). A turning mechanism (120, 120a) directs the seat belt webbing (62) and comprises a housing (122, 122a) fixed to a part (118, 118a) of the second frame portion (24). A support portion (182) includes a support surface (225) and has a snap attachment for attaching to the housing (122, 122a).
