Abstract: A surgical device for implantation of deformable intraocular lens into the eye through a relatively small incision made in the ocular tissue including a holder with receiver for a lens holder. A lens holder for a surgical device for implantation of deformable intraocular lens into the eye including a split tubular member having a fixed tubular portion and a moveable tubular portion connected together at a hinge. A method for implantation of deformable intraocular lens into the eye using the above-described surgical devices.

Abstract: An improved lens cartridge for use in a lens injecting device. The lens cartridge and lens injecting device define a surgical implantation device for inserting a deformable intraocular lens into the eye through a relatively small incision made in the ocular tissue. A preferred lens cartridge comprises a lens holding portion connected to a nozzle portion with a passageway extending therethrough, and including at least one groove in the passageway. Another preferred embodiment comprises a lens holding portion connected to a nozzle portion with an inwardly tapering passageway extending therethrough. A further preferred embodiment includes both the passageway groove feature and the inwardly tapering passageway feature.

Abstract: A deformable intraocular lens injection system comprising a lens injecting device and a lens cartridge. The lens injecting device comprises a tubular body provided with a side receiver and a movable plunger having a faceted tip configured to engage the deformable intraocular lens loaded in the lens cartridge without damaging the trailing haptic.

Abstract: A portable infusion pump assembly utilizing continuous drive propulsion means (8) to effect automatic and incremental displacement of a plunger (5) within a disposable syringe (3) so as to deliver accurately repeatable volumes of fluid from the syringe (3) over a predetermined period of time.Intermittent drive of the continuous drive propulsion means (8) is effected. Comparison of desired delivery rate with actual delivery rate is made by use of angular displacement signals received from a shaft encoder (10) attached to the shaft of the continuous propulsion means (8).This method of control also allows indirect measurement of fluid pressure in the syringe (3) without the need for a pressure sensor to be located in direct contact with the fluid being delivered.

Abstract: An implantable medication delivery system comprising an implantable unit with a refillable reservoir, a catheter connected thereto, and a pumping mechanism activated by a microcomputer or microprocessor for pumping medication from the reservoir through the catheter into the body. The implantable medication unit receives information and control commands via a telemetry link from an external controller unit having a microprocessor. The external controller receives feedback in the form of intermittent sampling of blood using enzyme strips and a reflectance meter and/or additional sensor(s) which measure(s) physiological parameter(s) such as heart rate or blood pressure or temperature or skin resistivity. The feedback information is processed by the external unit in accordance with a mathematical model of the patient and the relevant parameters are transmitted to the implanted unit which adjusts its delivery profile according to a prescribed algorithm.

Abstract: A subcutaneous delivery device assembly and method is provided. The assembly includes a subcutaneous delivery device comprising a catheter, a self-sealing input port at a first end of the catheter, an internal magnet adjacent to the self-sealing port and a valve at a second end of the catheter. The assembly further includes a corresponding external locator which is adapted to be magnetically located adjacent to the internal magnet and separator therefrom by a thin layer of human tissue. The assembly can be used to locate and stabilize a syringe needle during injection.
