Publication number: 20110098721Abstract: 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: ApplicationFiled: November 6, 2009Publication date: April 28, 2011Applicant: Abbott Medical Optics Inc.Inventors: Tuan (Tom) M.

Patent number: 6673022Abstract: A catheter has a pressure sensitive bladder at a distal end and a pressure transducer at a proximal end with the proximal end attached to a mammalian body and the bladder inserted within the mammalian body. The bladder partially filled with a gas responds to pressure changes within the body and the pressure transducer senses the changes via gaseous communication with the bladder. In one embodiment, the bladder is inserted in a human brain with the transducer mounted on a bolt affixed to the skull. Initial dissection of the brain tissue is effected by over-inflation of the bladder by a manual piston pump or a blunt ended slender rod. The transducer may be mounted on a bolt inserted within a hole drilled in the skull. An antimicrobial agent may be dispersed from openings in a seal between the bolt and the skull, from a porous seal, or from a ribbed or threaded outer surface of the bolt.Type: GrantFiled: July 18, 2000Date of Patent: January 6, 2004Assignee: InnerSpace Medical, Inc.Inventors: Donald Bobo, James Gerg
