Patent number: 8986240Abstract: An IOP control valve is disclosed. The IOP control valve comprises a corrugated membrane and a housing including a fluid inlet and a fluid outlet. The corrugated membrane is anchored within the housing to form a reference chamber on a first side of the corrugated membrane and a fluid flow channel on a second opposing side of the membrane. The reference chamber has a reference chamber pressure representative of atmospheric pressure. The fluid flow channel can selectively increase and decrease in size to permit fluid to flow from the fluid inlet to the fluid outlet. The corrugated membrane is configured to affect flow through the fluid flow channel from the fluid inlet to the fluid outlet by deflecting in response to pressure differentials of the reference chamber pressure and the fluid flow channel pressure acting on the opposing sides of the corrugated membrane.Type: GrantFiled: February 14, 2012Date of Patent: March 24, 2015Assignee: Alcon Research, Ltd.Inventors: Cesario P Dos Santos, Robert J Sanchez, Jr., Leslie A Field

Patent number: 7740619Abstract: An ophthalmic injection device includes a dispensing chamber housing with an inner surface that partially defines a dispensing chamber for holding a substance, a plunger fluidly sealed to the interior surface of the dispensing chamber housing, and a needle fluidly coupled to the dispensing chamber. A temperature control device partially surrounds the dispensing chamber housing and alters a temperature of the substance. A piston is coupled to the plunger at one end and to a spring at the other end. The spring provides a force to drive the piston and the plunger. An actuator is coupled to the lockout bar with which a button is configured to interface. The actuator moves the lockout bar when the substance reaches a temperature, thereby allowing the button to be activated so that the spring provides the force to drive the plunger. An incorporated stop whose measurements may vary allow the expelled dosage to vary accordingly.Type: GrantFiled: February 5, 2008Date of Patent: June 22, 2010Assignee: Alcon Research, Ltd.Inventors: Raffi Pinedjian, Robert J.
