International Classification:

A61F 900

US Classification:

606166, 606107, 606167, 604 22

Abstract:

A corneal incision device of the present invention includes a surgical blade and a frame having an inner surface with a configuration that is generally in the shape of a ring-like segment of a hollow sphere. The frame has an aperture therein to allow the surgical blade to be inserted through the frame beyond the inner surface. The aperture is sized and shaped to allow movement of the surgical blade in one axis. The device may have a protuberance affixed to the inner surface of the frame adjacent to the aperture disposed to distort a surface of a patients eye when the device is selectively positioned on the eye by a practitioner. The device has provisions for holding, advancing and withdrawing the surgical blade through the aperture, disposed on the frame. The device is releasably retained on the patients eye by fixation elements disposed on the inner surface of the frame. There is a handle affixed to the frame to facilitate the practitioners manipulation of device.

US Classification:

604/523000, 264/171120

Abstract:

The present invention provides systems and methods for reducing intraocular pressure, thereby to treat glaucoma and other disorders. The systems of the present invention include a shunt insertable across the clear cornea and a delivery device for inserting the shunt in the transcorneal position. The shunt has a body with a head at one end and a foot at the opposite end, and a channel therethrough permitting the passage of aqueous humor from the anterior chamber to the external surface of the cornea. A removable filter is positioned within the channel to regulate aqueous humor outflow and to resist the incursion of microorganisms.

Appl. No.:

8/646574

Inventors:

Neil Jolly - Brighton MA
Craig D. Newman - New York NY
Robert W. Pierce - Wrentham MA

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

A61B 1732

US Classification:

606167

Abstract:

This invention relates to an improved guarded surgical scalpel having a movable guard that can be retracted to expose the blade and that can be extended to cover the sharp cutting edge of the blade. The guard is telescopically mounted inside the blade handle and includes a deflectable top wall portion that holds a detent pin or that defines a radially extending flange. This detent pin or flange engages a slot having upturned ends that is formed in at least one side wall of the blade handle. The detent pin or flange is biased upwardly into the upturned ends of the slot to hold the guard in the retracted or extended position. The blade can include a tang having a notch formed therein. The distal end of one sidewall of the guard can be formed with a complementary notch such that when the distal end of the sidewall of the guard engages the proximal end of the blade, forward movement of the guard forces the blade off of the scalpel. A wedge mechanism is provided to urge the proximal end of the blade away from a blade carrier into engagement with the distal end of the sidewall of the guard.
