A syringe-like device having a chamber in which a pressurizing piston reciprocates. The chamber is connected on one end to a vial containing a drug to be delivered to an eye and on the other end to a needle or cannula for administering the drug to an eye. Pulling proximally backwards on the piston creates a vacuum in the chamber and draws the drug out of the vial. Upon release of the piston, a spring pushes the piston forward, pressurizing the chamber. Delivery of the drug is controlled by a roller pinching off a section of compliant tubing between the chamber and the cannula, with a design similar to a peristaltic pump. A one-way valve prevents the drug from being expelled back into the vial. The flow rate of the drug out of the cannula can be controlled by rotation of the roller.

Drug delivery device

A container for delivery of a surgical fluid to a surgical handpiece is disclosed. The container includes a volume for receiving the surgical fluid to be delivered to the handpiece and an end for removably engaging a receptacle in a surgical console and for fluidly coupling with a source of pressurized fluid in a surgical console.

Container for delivery of fluid to ophthalmic surgical handpiece

An apparatus for delivery of a surgical fluid to a surgical handpiece is disclosed. The apparatus generally includes a container and an adapter receiving one end of the container. The container holds the surgical fluid to be delivered to the handpiece. The adapter is for removably engaging a receptacle in a surgical console and for fluidly coupling with a source of pressurized fluid in a surgical console.

Apparatus for delivery of fluid to opthalmic surgical handpiece

A centrifuge bowl mount with a base and having one or more toggle members disposed thereon which are movable from a non-contact or non-engaging first positon to a contact or engaging second position in which they either (a) contact or engage the bowl or (b) move other members such as seal members disposed on the base or move push membes which in turn move the seal members to contact or engage the bowl.
