1. An apparatus for delivery of a surgical fluid to a surgical handpiece, comprising:
- a container having first and second portions, said first portion made from a deformable material and having a closed end, an open end, an outer surface, and a first volume for receiving a surgical fluid for delivery to a surgical handpiece, said second portion made from a material more rigid than said deformable material and having a first end, a second end, an outer surface, an inner surface, and a second volume receiving said first portion, said first end having an outlet for delivery of said surgical fluid, said second end having an aperture for receiving a pressurized fluid between said outer surface of said first portion and said inner surface of said second portion; and
an adapter having an outer wall, a first open end, a second open end, and a transverse wall coupled to said outer wall and having first and second sides, said first end of said adapter receiving said second end of said second portion, said second side of said transverse wall having an area for removably engaging a source of said pressurized fluid so that said source of said pressurized fluid is in fluid communication with said aperture, and said second side of said transverse wall having a geometry for providing a binary signal indicative of a particular kind of said surgical fluid.

Abstract
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.

13. A system for delivering a surgical fluid to a liquefracture handpiece, comprising:
-
a liquefracture handpiece having a pumping chamber;
a container having first and second portions, said first portion made from a deformable material and having a closed end, an open end, an outer surface, and a first volume for receiving a surgical fluid for delivery to a liquefracture handpiece, said second portion made from a material more rigid than said deformable material and having a first end, a second end, an outer surface, an inner surface, and a second volume receiving said first portion, said first end having an outlet for delivery of said surgical fluid, said second end having an aperture for receiving a pressurized fluid between said outer surface of said first portion and said inner surface of said second portion; and
an adapter having an outer wall, a first open end, a second open end, and a transverse wall coupled to said outer wall and having first and second sides, said first end of said adapter receiving said second end of said second portion, said second side of said transverse wall having an area for removably engaging a source of said pressurized fluid so that said source of said pressurized fluid is in fluid communication with said aperture;
a surgical console containing said source of said pressurized fluid and having a receptacle for removably receiving said adapter, said receptacle having a lumen for fluidly coupling said source of said pressurized fluid with said area of said second side of said transverse wall; and
tubing fluidly coupling said outlet of said second portion with said liquefracture handpiece;
whereby when said surgical console provides said pressurized fluid from said lumen, said pressurized fluid flows through said aperture and between said outer surface of said first portion and said inner surface of said second portion, and said surgical fluid is delivered to said pumping chamber by said tubing. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
