Publication number: 20230157873Abstract: 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.Type: ApplicationFiled: January 9, 2023Publication date: May 25, 2023Inventors: Jose Luis Lopez, Matthew Douglas McCawley, Brian William McDonell, Timothy C.

Patent number: 9987736Abstract: A punch centering block device can include a first block and a second block. The first block can define a first reference surface and a first notch extending along a first axis. The first reference surface can lay flush on a workpiece. The first axis can be transverse to the first reference surface. The second block can define a second reference surface and a second notch extending along a centered second axis. The second reference surface can lay flush on the workpiece. The second axis can be transverse to the second reference surface. The first block and the second block can selectively abut one another and render the first axis and second axis collinear to receive a punch. The punch is slidable against the first notch and the second notch during the marking operation.Type: GrantFiled: September 19, 2016Date of Patent: June 5, 2018Inventor: Salomon Valencia Arboleda

Publication number: 20130144317Abstract: A method of controlling a surgical system using position feedback control, includes selectively operating a cutter having a cutting mechanism, with the cutting mechanism having an inner cutting tube and an outer cutting tube. The outer cutting tube has a tissue-receiving port formed therein, and the inner cutting tube has a cutting edge axially displaceable relative the tissue receiving port to cut tissue therein. The method also includes sensing the displacement of the inner cutting tube relative to the outer cutting tube with a sensor and changing operational timing of a probe driver based on the displacement sensed by the sensor.Type: ApplicationFiled: December 1, 2011Publication date: June 6, 2013Inventor: Salomon Valencia

Publication number: 20080125712Abstract: An ophthalmic injection system is disclosed. The system has a dispensing member, a plunger, an actuation chamber, a lock mechanism, a lock stop, a port, a source of pressurized gas, and a shaft. The lock mechanism travels in the actuation chamber in an axial direction toward and away from a distal end of the dispensing member. The lock stop is located on the inner surface of the actuation chamber. The lock stop is engageable with the lock mechanism such that when the lock mechanism travels in the axial direction toward the distal end of the dispensing member to a first position located on a distal side of the lock stop, the lock mechanism cannot travel in a reverse direction away from the distal end of the dispensing member to a location on a proximal side of the lock stop.Type: ApplicationFiled: September 26, 2006Publication date: May 29, 2008Inventors: Bruno Dacquay, James Foster, Mark Hopkins, Lamar Kirchhevel, Cesario Dos Santos, Salomon Valencia

Publication number: 20080097379Abstract: A method is disclosed for delivering a quantity of a substance into an eye. By applying compressed gas into an actuation chamber, a separating member connected to a lock mechanism and a plunger is displaced. The plunger displaces the quantity of the substance from a dispensing member and into an eye. The plunger is retained in an extended position so that the quantity of the substance is not retracted back into the dispensing member when the dispensing member is removed from the eye.Type: ApplicationFiled: September 26, 2006Publication date: April 24, 2008Inventors: Bruno Dacquay, James Foster, Mark Hopkins, Lamar Kirchhevel, Cesario Dos Santos, Salomon Valencia
