Filed:

Jun 3, 2010

Appl. No.:

12/792898

Inventors:

David Anthony Downer - Fort Worth TX, US
Kyle Brown - Fort Worth TX, US
Dengzhu Yan - Arlington TX, US
Marshall Keith Proulx - Keller TX, US
Sushant Muchhala - Kennedale TX, US
Tu Cam Tran - Grapevine TX, US

Assignee:

Novartis AG - Basel

International Classification:

A61F 9/00

US Classification:

606107, 623 612

Abstract:

An intraocular lens delivery system includes an injector body having a bore surrounded by an inner wall. The system further includes a plunger configured to fit within the bore. The system also includes a plurality of deflectable members connected to the plunger and configured to contact the inner wall and to be deflected when the plunger is inserted within the bore. The deflectable members center the shaft and, when inserted within the injector body, contribute to producing a predetermined force resisting advancement of the plunger when deflected in the bore.

International Classification:

A61F 9/00

US Classification:

606107

Abstract:

A cartridge for an IOL delivery system that has a straight thinned walled distal nozzle. The transition region between the tapered folding portion of the cartridge and the nozzle contain reinforcing gussets to help prevent splitting of the cartridge. Flow leaders in the nozzle direct the flow of material during molding at the 12:00 o'clock position, positioning the weld line of the flow front at the 6:00 o'clock position.

International Classification:

A61F 2/16
B29D 11/00
A61F 9/00

US Classification:

623 627, 264 27, 606107

Abstract:

Embodiments of the present invention provide an intraocular lens with an optic zone having a first surface topology and a haptic zone having a second surface topology. The surface roughness of the haptic zone may be greater than the surface roughness of the optic zone. The surface topology of the optic zone may have a first surface geometry and the surface topology of the haptic zone may have a second surface geometry. The first and second surface geometries may retain lubrication fluid in a space formed therein. The haptics formed by the manufacturing process may have a reduced ability to adhere to the optic zone, such as when the lens is folded or advanced through a cannula.

International Classification:

A61F 2/16

Abstract:

Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a passage formed in a distal end portion of the intraocular lens injector. The passage may define an interior surface, and one or more rails may be formed on the interior surface so as to displace an optic of an intraocular lens (IOL) being advanced through the passage towards a portion of the interior surface disposed opposite the one or more rails.
