SURGICAL CASSETTE APPARATUS
First Claim
1. A surgical cassette arrangement comprising:
- a reservoir configured to hold fluid;
a collector configured to collect fluid; and
a flow selector valve arrangement coupled with a handpiece and having at least two ports configured to receive and transmit fluid, wherein a first port is coupled with the reservoir through a first fluid pathway and a second port is coupled with the collector through a second fluid pathway;
wherein the collector is configured to collect fluid received from the flow selector valve arrangement and from the reservoir.

Abstract
A surgical cassette arrangement is provided. The arrangement includes a flow selector valve configured to operate with a handpiece to selectively irrigate and aspirate fluid with respect to an ocular region. The flow selector valve includes at least three ports, with one port fluidly connectable to the handpiece. The arrangement further includes a reservoir fluidly connected to a second port of the flow selector valve via a first flow segment and configured to receive fluid from the flow selector valve, and a collector fluidly connected to a third port of the flow selector valve via a second flow segment and configured to receive fluid from the flow selector valve and from the reservoir. The flow selector valve selectively controls irrigation and aspiration flow to the handpiece and ocular region.

14. A method for selectively venting and aspirating fluid to and from a handpiece employed in an ocular surgical procedure, comprising:
-
providing a first pumping operation and a second pumping operation; and selecting operation between the first pumping operation and the second pumping operation using a flow selector valve; wherein the first pumping operation controls fluid flow to and from an eye using a first pump fluidly connecting the flow selector valve to a first fluid pathway via a first port in the flow selector valve and the second pumping operation controls fluid flow to and from the eye using a second pump fluidly connected to the flow selector valve via a second fluid pathway connected to a second port in the flow selector valve. - View Dependent Claims (15, 16, 17, 18, 19, 20)
