Patent number: 7255770Abstract: The present invention concerns methods for joining flexible polymer workpieces using light energy. These methods, referred to as laser welding, can be used to join thermoplastic or thermoset polymers. The laser welding method of the invention is applicable to the creation or repair of any article requiring the bonding of two flexible polymer components or a flexible polymer component and an inflexible polymer component.Type: GrantFiled: August 12, 2002Date of Patent: August 14, 2007Assignee: Mentor CorporationInventor: Lawrence Y. Wissman

Patent number: 7001370Abstract: Urine collection bags are provided that include features that facilitate easy insertion of a urinary catheter into a patient's bladder. In some implementations, the urine collection bag is formed of a soft, flexible material that is comfortable when it contacts the user's skin, easy to manipulate, and relatively noiseless during use.Type: GrantFiled: October 9, 2002Date of Patent: February 21, 2006Assignee: Mentor CorporationInventors: Thomas P. Kubalak, Dennis Femrite, William S. Nettekoven, Jerry Barber, Laura M. Calderon, Ronald Crouther, Christy R. Sweet, Lawrence Y. Wissman

Patent number: 6118913Abstract: A system for staking a haptic to an optic to form an intraocular lens using a laser beam operating near the infrared range with a coaxial aiming laser beam operating in the visible range. A portion of the haptic is inserted into the optic through a radial bore and is exposed through an axial bore spanning from the optic upper surface to the radial bore. The coaxial laser beams are collimated and then focused using a microscope objective through the axial bores, onto the exposed haptic. Aiming of the coaxial beams onto the optic and haptic is aided by the use of a magnifying CCD camera positioned with its optical axis at a 45.degree. angle to the optic horizontal plane. The coaxial lasers, which are typically focused to a minor diameter which is greater than or equal to the inner diameter of the axial bore, make contact with the exposed haptic. Consequently, the haptic is melted and is then allowed to cool, coalescing into a bead staking the haptic to the optic.Type: GrantFiled: March 20, 1998Date of Patent: September 12, 2000Assignee: Ciba Vision CorporationInventors: John J. O'Connor, Lawrence Y. Wissman
