First Claim
1. A surgical cassette arrangement coupled with a handpiece, the surgical cassette arrangement comprising:
- a surgical cassette, wherein the surgical cassette comprises;
a reservoir configured to hold fluid; and
a flow selector valve arrangement coupled with the handpiece and having a first port and a second port that are each configured to both receive and transmit fluid; and
a collector configured to collect fluid from the surgical cassette;
wherein the first port is coupled with the reservoir through a first fluid pathway within the surgical cassette and the 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 via the second fluid pathway and from the reservoir via a third fluid pathway.

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.
