Patent number: 10398863Abstract: A method of using CPAP equipment to sense cardiogenic oscillations in a patient's airflow, and to monitor and treat the patient's cardiac condition. The apparatus diagnoses cardiac morbidity conditions, such as the existence of arrhythmias or other cardiac abnormalities, and influences and optimizes cardiac stroke volume. The apparatus further monitors pulse-transit time, changes in the heart pre-ejection period, and the duration of the cardiac cycle.Type: GrantFiled: July 10, 2014Date of Patent: September 3, 2019Assignee: ResMed Pty LtdInventors: Chee Keong Phuah, Steven Paul Farrugia, Dion Charles Chewe Martin, Christine Wei Chih Chan

Patent number: 10314311Abstract: The present invention relates to a modified surface capable of having bacteriostatic and bactericidal activity when it is light irradiated, thus converting the surface of the substrate into a bacteriostatic and a bactericidal surface as many times as it is desired, and for a long time. According to the invention, the modified surface upon light irradiation avoids the attachment of a microorganism to this surface, inhibits the formation of a biofilm on this surface and destroys an already formed biofilm on this surface. These effects can be achieved as many times as it is desired, and for indefinite time.Type: GrantFiled: October 1, 2014Date of Patent: June 11, 2019Assignees: B.

Patent number: 9808140Abstract: A system for determining the shape of a surgical instrument includes an elongate instrument body having a selectively steerable distal tip, a pair of automatically controlled segments proximal to the selectively steerable distal tip, and a joint that couples the pair of adjacent automatically controlled segments together. An actuator changes an angle of the joint and a position encoder provides information associated with the joint angle. A controller receives the information associated with the angle of the joint and generates a three dimensional model of a shape of the instrument. A method for determining the three dimensional shape of an instrument includes providing axial position data to a controller, providing angular position data to the controller from a respective segment controller, and generating a three-dimensional model of a shape of said instrument using the axial position data and the angular position data.Type: GrantFiled: September 15, 2014Date of Patent: November 7, 2017Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Amir Belson, Paul DeWitt Frey, Christine Wei Hsien McElhaney, James Craig Milroy, Robert Matthew Ohline, Joseph M.

Patent number: 8845524Abstract: A steerable endoscope has an elongated body with a selectively steerable distal portion and an automatically controlled proximal portion. The endoscope body is inserted into a patient and the selectively steerable distal portion is used to select a desired path within the patient's body. When the endoscope body is advanced, an electronic motion controller operates the automatically controlled proximal portion to assume the selected curve of the selectively steerable distal portion. Another desired path is selected with the selectively steerable distal portion and the endoscope body is advanced again. As the endoscope body is further advanced, the selected curves propagate proximally along the endoscope body, and when the endoscope body is withdrawn proximally, the selected curves propagate distally along the endoscope body. This creates a serpentine motion in the endoscope body allowing it to negotiate tortuous curves along a desired path through or around and between organs within the body.Type: GrantFiled: November 19, 2010Date of Patent: September 30, 2014Assignee: Intuitive Surgical Operations, Inc.Inventors: Amir Belson, Paul DeWitt Frey, Christine Wei Hsien McElhaney, James Craig Milroy, Robert Matthew Ohline, Joseph M.
