  • Publication number: 20050246019
    Abstract: A two part IOL with a generally “L” or “S” shape but featuring straight or curved “V”-shaped structures which can be inserted through a very small opening by flexing the arms of the “V”-shaped structures up to or over each other is described. This IOL may be used in the anterior or posterior chamber of the eye for phakic or aphakic lenses. After insertion of the haptic 110 into the eye 1, any type of lens 200 may be attached, especially by use of cleats 300 and an eyelet 400. The haptic 110 is a high modulus skeletal frame and the lens 200 is preferably formed of a lower modulus material and is attachable to cleats 300 on the frame 110.

  • Patent number: 5094226
    Abstract: A device for engaging the big toe of a user to provide continuous passive motion to the first metatarsal phalangeal joint includes an electric motor situated within a box-like housing, a piston having a first end coupled to a drive shaft turned by the motor, a toe engaging attachment coupled to a second end of the piston, a rotatable foot support plate to accommodate the shift from right to left foot and vice versa, and a heel cradle for selective foot size adjustment. The rotational motion of the drive shaft is converted into reciprocating and substantially linear motion of the toe engaging attachment causing movement of the big toe by pushing on the plantar aspect upward, thus allowing for dorsi flexion of the joint. The toe engaging attachment is interchangeable depending on the degree of dorsi flexion desired. When the toe is to be put through a limited degree of dorsi flexion, a toe engaging attachment with a spring loaded plunger is used.

  • Patent number: 4056855
    Abstract: An intraocular lens and the method of its implantation through an incision in the eye. The assembly includes a lens member and a supporting wire initially in disassembled condition and adapted to be introduced independently through a small incision in the eye. The supporting wire has a base portion which is adapted to fit and be mounted behind the iris of the eye, and has a pair of resilient legs projecting from the pupil, forward of the iris which are adapted to receive a lens therebetween snapped into position by resiliently parting the legs while both components are located in the eye and thereby assembling and mounting the intraocular lens in position in the anterior portion of the eye for use.
