US Patent:

Filed:

Jul 27, 1992

Appl. No.:

07/900053

Inventors:

Larry W. Blake - Irvine CA

Assignee:

Pharmacia Upjohn Company - Irvine CA

International Classification:

B32B 3100

US Classification:

156245, 1562726, 1562733, 623 646

Abstract:

A lens, having an optical power surface, which may have multiple radii portions or aspherical portions as well as spherical portions, is molded in a coined old. A pair of core pins, positioned within the mold cavity during the lens forming process, will produce a pair of haptic-mounting holes within the lens. As the lenses are subsequently tumbled to remove flash, indentations will form adjacent to the haptic-mounting holes. These indentations allow for tangential attachment of the haptic to the lens which, in turn, enables maximum flexibility without exceeding the width of the optic.

Assignee:

Iovision, Inc. - Irvine CA

International Classification:

A61M 2700

US Classification:

604 8

Abstract:

An implant for use in the treatment of glaucoma is disclosed wherein the implant comprises an elastomeric plate having a non-valved elastomeric drainage tube attached thereto. The plate is elliptical in shape and curved so as to conform to the curvature of the eye. The plate is inserted into the eye in an incision made in the Tenon's capsule and sutured to the sclera. The drainage tube is tunnelled through the Tenon's capsule and cornea and inserted into the anterior chamber, thus providing patent fluid communication between the anterior chamber and the elastomeric plate. The flexible structure of the plate allows the plate to be easily inserted, thus reducing the surgical procedure length. In addition, the pliable material minimizes th risk of damage and trauma to surrounding tissues in the insertion process.

International Classification:

A61M 100

US Classification:

604 73

Abstract:

A flexible, compressible reservoir draws a substantially constant vacuum to permit uniform removal of fluid from a surgical incision through a wound drain catheter. The reservoir includes a compression spring interposed between a pair of congruent articulated plates. The spring provides biasing force to expand the reservoir and create a vacuum therein. Each of the articulated plates has a central member hinged on opposite sides to wing members. As the reservoir expands, the wing members pivot relative to the central members to decrease the effective area to which the spring force is applied. Such decrease in the effective area permits the spring force per unit of area to remain more nearly constant, and thus, reduces changes in reservoir vacuum.

International Classification:

A61M 100

US Classification:

604126

Abstract:

A fluid T-coupling comprising a through fluid flow path, and an intersecting vent path, wherein the vent path is integrally molded within the filtered bayonet connector to be used with an aspirator to control the level of vacuum communicated to an irrigation/aspiration handpiece during eye surgery.

International Classification:

A61M 2700

US Classification:

604 93

Abstract:

The wound drain catheter of the present invention is comprised of a drain portion connected to an outflow tube portion. The drain portion comprises a central core with plural T-shaped members projecting therefrom to form plural lumens having respective longitudinal grooves for fluid communication with the wound. This drain has a uniform cross-sectional area and is preferably made from a silicone elastomer having a durometer shore between 40 and 70 shore A. Such uniform cross-sectional area provides added strength to prevent the drain from breaking during its removal from the patient's body, and the silicone elastomer provides sufficient elasticity to permit the cross-sectional area of the drain to decrease by at least 30 percent when a pulling force is applied thereto, thereby reducing the gripping force of tissue surrounding the wound.
