Patent number: 9327070Abstract: This disclosure describes techniques implemented by a medical device, such as an implantable medical device (IMD). The IMD may be configured to detect a posture state of a patient, and deliver posture-responsive therapy. In particular, the IMD not only detects the posture state of a patient, but also detects timing associated with the detected posture state, such as the time of day, the day of the week, or a specific time of day associated with a specific day. In this way, the posture-responsive therapy delivered by the IMD may be dependent not only on the posture state of the patient, but also on the timing associated with the posture state. The same posture state, therefore, may result in different types of therapy to the patient if the same posture occurs at different times of the day.Type: GrantFiled: April 30, 2009Date of Patent: May 3, 2016Assignee: Medtronic, Inc.Inventors: Dennis M. Skelton, Jon P. Davis, Timothy J. Denison

Patent number: 9259541Abstract: A warming gas flows through a jacket to heat an insufflation gas flowing in a separate tube, thereby reducing cost and disposable waste. The heated warming gas may be filtered to sterilize or maintain sterility and released to atmosphere after heating the flowing insufflation gas. Alternatively the warming gas may be reheated and recirculated through the jacket, with an additional tube being used within the jacket so that the warming gas flows in both directions lengthwise. As an alternative to separate tubes, a single, multi-lumen tube may be used. The insufflation gas may be CO2 and the warming gas may be room air. The heating element and sensors may be separate from the disposable unit of a heated insufflation set, and need not be re-sterilized prior to or after use in surgery. The heat is constantly maintained, thereby eliminating “cold spots” caused by the natural cycling of the resistance heaters.Type: GrantFiled: May 21, 2013Date of Patent: February 16, 2016Inventor: John Temple
