Filed:

Sep 8, 2000

Appl. No.:

09/658869

Inventors:

Randall J. Olson - Salt Lake City UT 84132
Rolf Meyer - CH-2562 Biel, CH

International Classification:

A61F 900

US Classification:

606166

Abstract:

The device comprises a tubular housing having an axis and comprising a suction ring on its lower end face with an annular recess communicating with a corretor for connection to a suction pump. The housing has first stop means and second stop means. A tubular insert is mounted in the housing for rotation around the axis and axially displacable. The insert has a third stop means cooperating with the first stop means for defining an extended position of the insert and a fourth stop means coacting with the second stop means for defining a retracted position of the insert. The insert further has a micrometer female thread. A tubular knife holder with a knife for cutting a circular cut into the cornea is mounted in the insert. The knife holder has a micrometer male thread threaded into the female thread and a head. A scale and a marking on the head and on the insert are provided for preselecting a depth of the cut in the extended position of the insert.

Inventors:

Randall J. Olson - Salt Lake City UT, US

International Classification:

A61F 2/16

US Classification:

623 643

Abstract:

A vision correction system comprising an intraocular lens having a lens body and one or more haptics is provided. The lens body may be configured to be positioned posteriorly to an iris of an eye and may have a convex anterior surface, a concave posterior surface, and a circumferential edge having a rounded anterior portion and a rounded posterior portion. Haptics may extend at an anterior angle from the lens body and be configured to contact the ciliary sulcus of an eye. The haptics may secure the intraocular lens in the eye in a relatively fixed position and prevent rotation of the lens over time.

International Classification:

A61M 5/32
A61M 5/00

US Classification:

604506, 604272, 604239

Abstract:

A hypodermic needle system and method for reducing the incidence of infections due to administering fluids by injection to humans or animals is provided. The hypodermic needle system may include a needle with an insert disposed within its hollow channel to substantially prevent bacteria, fungi and/or other organisms/contaminants, which may be present on the exterior surface to be penetrated, from adhering to the inner surfaces of the needle's channel or become trapped in the needle bore. The hypodermic needle system may include a film that covers at least one surface of the needle or insert, and/or have a bent or curved tip to reduce the ability of infectious agents to adhere to said surface/space within the needle. Additionally, the hypodermic needle system may include an anti-infection agent, such as an antibiotic or antiseptic to further reduce the incidence of infections, and may include an attachment member which reduces the risk of infection.

US Classification:

623 634

Abstract:

A vision correction system comprising an intraocular lens having a lens body and one or more haptics is provided. The lens body may be configured to be positioned posteriorly to an iris of an eye and may have a convex anterior surface, a concave posterior surface, and a circumferential edge having a rounded anterior portion and a rounded posterior portion. Haptics may extend at an anterior angle from the lens body and be configured to contact the ciliary sulcus of an eye. The haptics and/or hydrophobic forces between this lens body and a second intraocular lens may secure the lens body in the eye in a relatively fixed position and prevent rotation of the lens over time.

International Classification:

A61B 17/3211
A61F 9/013

Abstract:

A surgical cutting device may be made of one or more pieces and include a front edge having a plurality of incision points. The incision points may be the forwardmost points of the front edge and may be separated by a recessed portion. The surgical cutting device may also have lateral edges that are non-cutting surfaces.
