1. A hand-held pump system, the system comprising:
- a pumping portion comprising;
a first channel comprising at least two compressible channels, each of the compressible channels adapted to create a separate fluid flow; and
a fluid port in fluid communication with the two compressible channels; and
a drive portion comprising;
a housing;
a rotor disposed in the housing and having a helical scroll engaged with the compressible channels, the helical scroll comprising;
a first portion having an increasing radius along a first length of the rotor in the direction of fluid flow, the radius increasing from a first end of the rotor to a maximum value; and
a second portion having a constant radius along a second length of the rotor, the helical scroll compresses the compressible channels in a peristaltic manner to capture and move fluid along the compressible channels; and
a slot formed in the housing, the slot including a transverse portion, the fluid port receivable into the slot and secured into the transverse portion of the slot by rotation of the pumping portion relative to the drive portion.

Abstract
Ocular surgery may be performed by a variety of systems, processes, and techniques. In certain implementations, a system and a process for ocular surgery may include the ability to draw ocular fluid into a channel of a hand-held pump system and separate the fluid into multiple compressible channels to create multiple flows. The system and the process may also include the ability to peristaltically pump the fluid through the compressible channels.

11. A hand-held pump system, the system comprising:
-
a pumping portion comprising; an outer shell; an inner shell located within the outer shell; a slot formed between the outer shell and the inner shell; and a first channel comprising at least two compressible channels, each of the compressible channels adapted to create a separate fluid flow; a drive portion comprising; a housing comprising a distal end, the distal end insertable into the slot between the outer shell and the inner shell to couple the drive portion and the pumping portion; a rotor disposed within the housing, the rotor having a helical scroll engaged with the compressible channels, the helical scroll comprising; a first portion having an increasing radius along a first length of the rotor in the direction of fluid flow, the radius increasing from a first end of the rotor to a maximum value; and a second portion having a constant radius along a second length of the rotor, the helical scroll compresses the compressible channels in a peristaltic manner to capture and move fluid along the compressible channels. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
