Filed:

Jan 27, 2000

Appl. No.:

09/492729

Inventors:

Bryan Loomas - Santa Clara CA
James Davenport - Fallbrook CA
Mark Mathis - Fremont CA

Assignee:

Addition Technology, Inc. - Fremont CA

International Classification:

A61F 900

US Classification:

606166, 606190, 30301

Abstract:

This invention is a surgical device for producing a generally circular, interlamellar pathway within the corneal stroma of the eye. The device is made up of three major components: a vacuum centering guide having an inner bore which fits at one end against the front of the eye, a barrel which fits within the inner bore of the centering guide and to which is attached the third major component, a generally circular dissecting ring. The dissecting ring is shaped in such way that when an eye surgeon twists the barrel to which the ring is attached, the ring moves through the interlamellar space in the stroma producing the desired channel or pathway. The centering guide may optionally include a ring having one or more pins which firmly engage the corneas epiphilium. The constituent parts of the surgical device, particularly the dissecting ring, also form a part of this invention. A split ring, or intracorneal ring (âICRâ), is inserted into the intrastromal passageway produced by the inventive device.

International Classification:

A61B 17/08

US Classification:

606157

Abstract:

A lung volume reduction system is disclosed comprising an implantable device adapted to be delivered to a lung airway of a patient in a delivery configuration and to change to a deployed configuration to bend the lung airway. The invention also discloses a method of bending a lung airway of a patient comprising inserting a device into the airway in a delivery configuration and bending the device into a deployed configuration, thereby bending the airway.

Abstract:

A lung volume reduction system is disclosed comprising an elongate implantable device adapted to be delivered to a lung airway of a patient in a delivery configuration and to change to a deployed configuration to compress lung tissue. The implant may be longer in axial length than an axial length of the target axial region in which it is deployed. Deployment may involve allowing an end of the implant to move relative to surrounding tissue while the implant is progressively deployed.

The dissecting ring is shaped in such way that when an eye surgeon twists the barrel to which the ring is attached, the ring moves through the interlamellar space in the stroma producing the desired channel or pathway. The centering guide may optionally include a ring having one or more pins which firmly engage the cornea's epiphilium. The constituent parts of the surgical device, particularly the dissecting ring, also form a part of this invention. A split ring, or intracorneal ring (“ICR”), is inserted into the intrastromal passageway produced by the inventive device. The ICR changes the shape of the cornea and, in doing so, provides a chosen measure of visual correction.
