  • Patent number: 8617179
    Abstract: A new connecting mechanism for the Valtchev® uterine mobilizer, model VUM-6 having a straight tube with a locking wheel attached close to one end of the tube pivotally mounted in a housing of the space bar and maintained by a spring loaded pin in realizable way. The another end of the tube is attached to a piston pivotally mounted and maintained within a hole in the head of the uterine mobilizer via the tube engaging a connecting slot in the head, and adapted to be disassembled by first releasing the locking wheel of the tube from the space bar and second, by rotating the tube in a prescribed degree which will align the tube with the vertical slot allowing removal of the tube with attached piston from the head. The distal end of a rod is bended 15°, which allows retroversion of the head at the same degree.

  • Patent number: 8495809
    Abstract: A gynecological instrument for delineating the fornix of the vagina during laparoscopic operations having a solid ring with a guiding groove for easy and safe opening of the vagina laparoscopically. The solid ring has a protrusion outward which pushes the vaginal wall toward the peritoneal cavity, creating a bulging of the vaginal wall, making it easily identifiable. The solid ring is permanently attached to the proximal end of the base by a semi-cylindrical wall which creates a window anteriorly, for better visualization of the cervix and easy insertion of a cannula or delineator into the uterine cavity. The vaginal delineator is locked to the head of the uterine mobilizer by inserting the locking end of a cannula, delineator or vaginal delineator lock, through the hole of the delineator and into the head of the uterine mobilizer. An elastic diaphragm is provided with different sizes for obstruction of the vagina, which does not allow flow in any direction.

  • Patent number: 8347888
    Abstract: A gynaecological instrument for delineating the fornix of the vagina during laparoscopic surgeries having a spring, which proximal end is securely affixed to a distal end of a solid ring and the distal end of the spring is securely affixed to a base. The extension of the base can be inserted into the head of the Valtchev® Uterine Mobilizer and locked in place. When the delineator is pushed toward the fornix of the vagina the solid ring is self-adjusting to the angle of the of the fornix and the length of the cervix. An elastic plastic ring is provided, for placing on the solid ring, in order to protect the ring and instrument which is used to open the vagina laparoscopically.

  • Publication number: 20120046517
    Abstract: A method for treating female stress urinary incontinence by implantable tapes. One embodiment are woven and knitted tapes having only macropores, a macropore is constructed by single threads, the threads at the crossing areas are bonded by heating them to the melting point of the surface of the threads. Other embodiment is molded tapes, having only macropores, a macropore is constructed by single threads. The crossing crossing areas of the threads may have a simple crossing configuration, a spherical crossing configuration and a cubical crossing configuration. A molded tape having one or three sections which have different construction. References Cited 1. Uster F C, Chaser J & Tuttle Jr. LLD. Use of Matrix mesh in the repair of incision Hernias.

    Abstract: A gynaecological instrument for delineating the fornix of the vagina during laparoscopic surgeries having a spring, which proximal end is affixed to a solid ring and the distal end is affixed to a base. The extension of the base can be inserted into the head of the Valtchev® Uterine Mobilizer and locked in place. The solid ring can be tilted in any direction, and can come closer to the base, allowing automatic adjustment for the angles of the fornix of the vagina and the cervical length.
