摘要： 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.

摘要： 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.

摘要： 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 the risk of damage and trauma to surrounding tissues in the insertion process.

摘要： 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. At least one hole is made in the plate to facilitate the formation of a tethered scar tissue bubble, referred to a bleb, to form around the carrier plate. The scar tissue will grow through the hole or holes and pull the perimeter of the bubble towards the carrier plate at the hole locations to tether the formation of the bleb to the carrier plate and finally to the sclera tissue. 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 the risk of damage and trauma to surrounding tissues in the insertion process.

摘要： This invention discloses devices for use with an ophthalmologic insertor apparatus. In one embodiment, the device is a flexible, stretchable sleeve holder adapted to fit over a deformable sleeve that houses an implant. The sleeve holder facilitates loading of an implant into the sleeve by providing a suitable gripping surface. Application of a compressive force to the sleeve holder further allows the implant to be immobilized within the sleeve. After loading of the implant into the sleeve, the holder may be used as a collar or hub to secure the sleeve to an insertor hand-piece. Methods for loading implants into delivery sleeves, methods for attaching sleeves to inserters, and methods for delivering implants to an incision are also disclosed.

摘要： 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 curved so as to conform to the spherical anatomy of the eyeball. An annular sloped wall extends from the plate and surrounds the opening of the drainage tube into the plate. The plate is inserted beneath Tenon's capsule and sutured to the sclera utilizing temporary and non-dissolving permanent sutures. The annular wall provides a temporary sealing surface against the sclera. The drainage tube is tunnelled through the sclera and cornea and inserted into the anterior chamber, thus providing fluid communication between the anterior chamber and the elastomeric plate. The annular wall around the tube forms a temporary seal which restricts the drainage of aqueous fluid until formation of the bleb is completed. After bleb formation occurs, the temporary sutures around the wall are removed or dissolve. Once the temporary sutures are gone, the portion of the plate that is not stitched to the sclera floats within the bleb and breaks the seal between the implant and the sclera. Once the seal is broken, unrestricted flow between the anterior chamber and bleb is maintained.

摘要： 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 mold. 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.
