Patent number: 9839439Abstract: A force transmission transmits a force received by two rotational inputs to an output gimbal plate. Two capstans receive the rotational input. The capstans drive cables connected to three levers. A cable is connected directly from each of the capstans to one of two levers. Another cable is connected to both capstans and passes over a pulley rotatably coupled to the third lever. Each of three linkages has a first end coupled to one of the three levers and a second end coupled to the output gimbal plate. Rotation of each of the first and the second input capstans causes the three cables to move the three levers such that there is no net movement of the three seconds ends of the linkages with respect to the center of motion of the output gimbal plate. The output gimbal plate may orient a mechanically actuated surgical tool.Type: GrantFiled: August 15, 2014Date of Patent: December 12, 2017Assignee: Intuitive Surgical Operations, Inc.Inventors: Thomas G. Cooper, S. Christopher Anderson

Patent number: 9826908Abstract: The present disclosure discloses a device, system and method for testing cardiac exercise functions. Chronotropic Competence Indices (CCIs) are proposed to quantitatively describe the adaptation capability of cardiopulmonary system in response to exercise intensity variation in terms of heart rate changes, and thereby describes the dynamic process of the heart in the body metabolic process. The present disclosure discloses a device which measures the CCIs in real time by using the wearable technology, and referred to as Cardiac Exercise Test (CET). Compared with the Cardiopulmonary Exercise Testing (CPX) and parameters measured by the CPX such as a maximum oxygen uptake, the CCIs have clear clinical meanings and specific normal reference values; and the CET reduces the risk of the test. It is simple to use, and can be used anytime anywhere. It is of great importance in wide clinical applications, and is of great significance in prevention and rehabilitation of cardiopulmonary disease.Type: GrantFiled: April 28, 2016Date of Patent: November 28, 2017Assignee: SmartHealth Electronics Ltd.Inventor: Jiankang Wu

Patent number: 9820802Abstract: A method and system for increasing safety of cardiac ablation procedures comprises a computer based system that monitors the esophageal temperature, and a fluoroscopy (medical images) based cardiac mapping system for cryoballoon or radiofrequency (RF) ablations. The esophageal temperature is monitored utilizing an esophageal probe which may have any number of temperature sensing members. The esophageal probe may also have pre-formed shape. During atrial fibrillation ablations, based on a pre-determined increase in esophageal temperature (from any thermistor), the computer based system activates different levels of alarm(s), and/or initiates ablation energy interrupt based on pre-defined programmed values. The method and system is also used for guiding placement of cryoballoon and performing cryoablations. The placement of cryoballoon catheter or a circular catheter is based on superimposing a high resolution (dye injected) image and a live fluoroscopy image and adjusting transparency between the two images.Type: GrantFiled: July 13, 2016Date of Patent: November 21, 2017Assignee: American Medical Technologies, LLCInventors: Birinder R.

Patent number: 9814882Abstract: A rechargeable-battery Implantable Medical Device (IMD) is disclosed including a primary battery which can be used as a back up to power critical loads in the IMD when the rechargeable battery is undervoltage and other non-critical loads are thus decoupled from the rechargeable battery. A rechargeable battery undervoltage detector provides at least one rechargeable battery undervoltage control signal to a power supply selector, which is used to set the power supply for the critical loads either to the rechargeable battery voltage when the rechargeable battery is not undervoltage, or to the primary battery voltage when the rechargeable battery is undervoltage. Circuitry for detecting the rechargeable battery undervoltage condition may be included as part of the critical loads, and so the undervoltage control signal(s) is reliably generated in a manner to additionally decouple the rechargeable battery from the load to prevent further rechargeable battery depletion.Type: GrantFiled: May 9, 2016Date of Patent: November 14, 2017Assignee: Boston Scientific Neuromodulation CorporationInventors: Goran N.
