Patent number: 5163927Abstract: An everting catheter system comprising an outer tube having an outer catheter lumen and an opening leading from the outer catheter lumen, an inner catheter movable longitudinally in the outer catheter lumen and having an inner catheter lumen and an everting element coupled to the outer catheter and the inner catheter so that with movement of the inner catheter distally in the outer catheter lumen, the everting element can be everted through the opening. An elongated instrument is movable longitudinally in the inner catheter lumen relative to the inner catheter. Indicia are provided on the inner catheter and the instrument for indicating at least one longitudinal position of the instrument relative to the distal end of the everting element.Type: GrantFiled: October 17, 1991Date of Patent: November 17, 1992Assignee: Imagyn Medical, Inc.Inventors: Gary Woker, Keith Tholin, Stanley L. Van Gent

Patent number: 4978354Abstract: A method of making an intraocular lens including providing a fixation member having a proximal end portion with the proximal end portion including an elongated filament, converting a region of said filament at said proximal end portion from a first configuration into a second configuration which is adapted to provide a mechanical interlock and molding an optic about the proximal end portion of the fixation member to form a mechanical interlock between the second configuration and the optic and to attach the fixation member to the optic.Type: GrantFiled: November 2, 1989Date of Patent: December 18, 1990Assignee: Allergan, Inc.Inventor: Stanley L. Van Gent

Patent number: 4955889Abstract: An apparatus is disclosed for inserting a lens into an eye. The apparatus comprises a cradle acting to hold the lens, e.g., in a deformed state, prior to insertion of the lens into the eye, the cradle being constructed, preferably of a shape memory alloy, so as to release the lens in response to a change in temperature; and an insertion assembly associated with the cradle and acting to insert, and preferably withdraw, the cradle into, and preferably from, the eye.Type: GrantFiled: February 6, 1989Date of Patent: September 11, 1990Assignee: Allergan, Inc.Inventor: Stanley L. Van Gent

Patent number: 4938767Abstract: A method of making an intraocular lens including providing a fixation member having a proximal end portion with the proximal end portion including an elongated filament, converting a region of said filament at said proximal end portion from a first configuration into a second configuration which is adapted to provide a mechanical interlock and molding an optic about the proximal end portion of the fixation member to form a mechanical interlock between the second configuration and the optic and to attach the fixation member to the optic.Type: GrantFiled: April 25, 1989Date of Patent: July 3, 1990Assignee: Allergan, Inc.Inventors: Albert C. Ting, Timothy R. Willis, F. Richard Christ, Steven R. Bacich, Dean K. Pettit, Stanley L. Van Gent, Jeffrey C. Day

Patent number: 4894062Abstract: An intraocular lens comprising a deformable optic and first and second fixation members. Each of the fixation members has a proximal end portion. First and second elongated anchors are coupled to the proximal end portions of the fixation members, respectively, and the anchors and the proximal end portions are within peripheral regions of the optic so that the anchors can assist in attaching the fixation members to the optic. The anchors are spaced apart so that the deformable optic can be folded to facilitate insertion of the optic through a relatively small incision into the eye.Type: GrantFiled: December 2, 1988Date of Patent: January 16, 1990Assignee: Allergan, Inc.Inventors: Patrica M. Knight, Vladimir Portnoy, F. Richard Christ, Alan E. Alosio, Stanley L. Van Gent, Lyle E. Paul

Patent number: 4759359Abstract: A lens implantation instrument includes first and second prongs connected together in a forceps-like configuration that is adapted to be grasped in the hand of a user for purposes of holding an intraocular lens to be implanted in an eye. The first prong has a distal end portion that defines a trough extending distally, the trough having a size and shape adapted to receive at least a portion of the optic of the lens with the optic in a folded configuration, and the second prong has a distal end portion that extends generally parallel to the trough, the distal end portion of the second prong having a size and shape adapted to fit at least partially into the trough.Type: GrantFiled: August 31, 1987Date of Patent: July 26, 1988Assignee: Allergan, Inc.Inventors: Timothy R. Willis, Lyle E. Paul, Stanley L. Van Gent
