Abstract
A capsulorhexis device is disclosed. The capsulorhexis device includes a tip portion, a vacuum channel, and a flexible membrane. The vacuum channel extends through the tip portion. Further, the vacuum channel is operatively connected to a vacuum source. The tip portion further includes a port formed therethrough. The port is in communication with the vacuum channel. The flexible membrane is positioned with the vacuum channel. The flexible membrane permits a predetermined level of vacuum to reach the port without causing aspiration of tissue through the vacuum channel.
Claims21
A capsulorhexis device, comprising:
- a tip portion;
- a vacuum channel extending through at least the tip portion, the vacuum channel configured to couple to a vacuum source;
- wherein the tip portion further includes a port in communication with the vacuum channel;
- and
- a flexible membrane positioned within the vacuum channel;
- the flexible membrane permitting a predetermined level of vacuum to reach the port without causing aspiration through the vacuum channel.
(canceled)
A disposable capsulorhexis device, comprising:
- a handle portion;
- a tip portion;
- a vacuum channel extending through the tip portion and the handle portion, the vacuum channel configured to be coupled to a vacuum source;
- wherein the vacuum may be selectively communicated to the port;
- wherein the tip portion further includes a port positioned adjacent a distal end of the tip portion, the port being in communication with the vacuum channel;
- and
- a flexible membrane secured to an interior wall of the vacuum channel, proximally of the port, the flexible membrane permitting a predetermined level of vacuum to reach the port without causing aspiration through the vacuum channel.
