Patent number: 9271806Abstract: A foot pedal control for a surgical system, e.g., an ophthalmic surgery system, that adjusts to a number of different sizes of user's shoes. The foot pedal control has a treadle on which a user places his or her foot and a sensor that tracks the movements thereof. Adjustable lateral guides mount to the treadle and conform to both sides of the foot. The guides are shaped and positioned to conform to a wide variety of feet or shoes, and may easily be adjusted between users. A retractable heel stop converts between up for reference and down to enhance movement of the user's foot. A convertible handle may be stowed in a down position parallel to a base or pivoted up over the treadle for protection and ease of movement of the foot pedal control. The foot pedal control may be wireless and have various other electronic controls, and may have a dual-control treadle.Type: GrantFiled: January 17, 2014Date of Patent: March 1, 2016Assignee: Abbott Medical Optics Inc.Inventors: Tuan M Tran, James Gerg

Patent number: 9232921Abstract: A system and method for intracranial access is disclosed. In particular, a drill stop is shown providing a way to control the penetration of a drill bit as an access hole into the brain is being formed. Access to a desired location is achieved using a catheter guide device. Also disclosed is a mechanism by which multiple diagnostic and treatment devices can be placed at a desired location in brain tissue without the need for more than one access hole. A drainage catheter is disclosed with a mechanism to allow both drainage and to allow intracranial pressure measurement.Type: GrantFiled: June 2, 2010Date of Patent: January 12, 2016Assignee: InnerSpace Medical, Inc.Inventors: Donald E.

Patent number: 9149568Abstract: The invention is generally directed to systems and methods for fluid control, and more particularly to systems and methods for power and flow rate control for aspiration. In accordance with one embodiment, an aspiration system includes an aspiration line having distal and proximal ends and an aspiration port defined in the distal end; a fluid transport device operatively coupled to the proximal end of the aspiration line; and a flow restrictor operatively coupled to the aspiration line in between the fluid transport device and the aspiration port. To measure occlusion within the line, first and second pressure sensors are utilized, the first sensor being operatively coupled to the aspiration line between the port and the restrictor and the second sensor being operatively coupled to the aspiration line between the restrictor and the fluid transport device. The pressure differential between the two sensors can provide an indication of the onset, presence, and/or elimination of an occlusion.Type: GrantFiled: September 23, 2011Date of Patent: October 6, 2015Assignee: Abbott Medical Optics Inc.Inventors: James Gerg, Carina Reisin
