Abstract: Systems and methods are disclosed for reducing pulsations in peristaltic pumps. In some examples, a cassette comprises a cassette body and a flexible sheet joined to the cassette body, wherein a transition region of the flexible sheet comprises at least one ridge that has a maximum height at a position that is offset from a center line of a cassette body transition channel. In some examples, a cassette body transition channel comprises side walls that taper toward an active region of the fluid path and/or toward a bottom of the transition channel. An example method of operating a peristaltic pump comprises operating rollers at a higher speed during portions of a revolution that otherwise would result in a lower than average flow rate and at a lower speed during portions of the revolution that otherwise would result in a higher than average flow rate.

Abstract: In some embodiments, a vitrectomy probe may include an inner cutting tube reciprocating in an outer tube. The outer tube includes a side port and the inner tube includes a distal cutting port, and, in some embodiments, an additional side port. In some embodiments, the inner tube may also include a flat upper edge that cuts across the outer tube side port. In some embodiments, a diaphragm drives the inner tube and may have an open-stroke side with a lower hardness material than a closed-stroke side. In some embodiments, an aspiration tube coupled to the vitrectomy probe may include a first aspiration tubing and a second aspiration tubing with a lower hardness than the first aspiration tubing. In some embodiments, the vitrectomy probe may be coupled to pneumatic tubing that is stepped or tapered.

Abstract: In one exemplary aspect, the present disclosure is directed to a system. The system includes a pneumatic surgical instrument and a surgical console operable to provide compressed gas to the pneumatic surgical instrument. Additionally, the system includes a pneumatic drive line coupling the pneumatic surgical instrument to the surgical console. The pneumatic drive line has an internal bore configured to deliver the compressed gas to the pneumatic surgical instrument. The internal bore has a non-uniform cross-section along a length of the pneumatic drive line.

Abstract: An ultrasonic cutting tip has a hollow shaft with a proximal and distal end. The proximal end is configured to be attached to an ultrasonic hand piece, and the distal end has a smooth continuous surface. An opening is located near the distal end of the hollow shaft. The opening is configured to cut vitreous when the cutting tip is vibrated ultrasonically in a torsional manner.

Abstract: Provided herein are vitrectomy instruments and related systems and methods in which the vitrectomy instruments may include a forward needle stop and a cutter stop to reduce dimensional variation of a cutter of the vitrectomy instruments, allowing for a location of the port formed in a needle of the cutter to be positioned closer to a distal tip of the cutter. With the port located closer to a distal end of the cutter, the port is able to be positioned closer to the retina of an eye.
