Patent number: 10265137Abstract: Systems, methods, and devices are provided for assisting or performing guided interventional procedures using custom templates. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A template is then manufactured containing guide elements. During a procedure, the template may be aligned to the patient and instruments passed though the guide elements and into various targets. The template may be aligned using one or more of, for example, a position sensing system or a live imaging modality to register the patient to the template. The system makes optional use of devices designed to immobilize or track an organ during therapy.Type: GrantFiled: September 30, 2016Date of Patent: April 23, 2019Inventor: Neil Glossop

Patent number: 10252068Abstract: An implantable medical device having a sensing module and a control module is configured to receive a cardiac electrical signal and sense events from the cardiac electrical signal received via electrodes carried by a medical electrical lead when the medical electrical lead is coupled to the implantable medical device. The control module coupled is configured to detect non-sustained tachyarrhythmia (NST) episodes based on sensed event intervals and determine if the sensed event intervals during the detected NST episode satisfy oversensing criteria. If the oversensing criteria are satisfied, the control module determines whether the detected NST episode satisfies non-lead related oversensing criteria and withholds a lead integrity alert when the NST episode meeting the oversensing criteria is determined to satisfy non-lead related oversensing criteria.Type: GrantFiled: November 6, 2015Date of Patent: April 9, 2019Assignee: Medtronic, Inc.Inventors: Bruce D. Gunderson, Jian Cao

Patent number: 10213609Abstract: Devices, systems, and methods are disclosed for relaying information from a cardiac pacemaker to an external device. Logic on the pacemaker modulates a heartbeat clock of the pacemaker to encode information onto a blood pressure sequence by adding or subtracting a small subinterval to or from a pulse repetition interval of the pacemaker. A muscle stimulator beats the heart according to the modulated sequence. A monitoring device external to the body monitors the blood pressure to retrieve the encoded information, or message. The encoded information is then decoded to determine the information in the message. This information may concern the pacemaker as well as other devices within the body that communicate with the pacemaker such as blood monitors, etc. Since the message is conveyed via simple modulation of the heart beat intervals, no separate transmitter is required in the pacemaker which would otherwise increase cost and decrease battery life.Type: GrantFiled: September 30, 2015Date of Patent: February 26, 2019Assignee: AT&T Mobility II LLCInventors: Sheldon Kent Meredith, Brandon B Hilliard, Mario Kosseifi

Patent number: 10092188Abstract: The invention provides methods and compositions for determining whether a subject containing a stent immobilized in a blood vessel has asymptomatic stent thrombosis or is at risk of developing clinically symptomatic stent thrombosis. In one approach, the method involves imaging a region of the blood vessel that contains the stent using a probe that contains a fluorochrome, for example, a near-infrared fluorochrome, and a targeting moiety that binds a molecular marker indicative of the presence of asymptomatic stent thrombosis or the development of symptomatic stent thrombosis. To the extent that the subject displays one or more such markers, the probe binds to the markers and increases the local concentration of the probe in the vicinity of the stent. The imaging method identifies those patients that display a higher density of such markers in the vicinity of the stent. As a result, those patients can be monitored for, and/or treated to prevent, symptomatic stent thrombosis.Type: GrantFiled: September 30, 2014Date of Patent: October 9, 2018Assignee: VisEn Medical, Inc.Inventors: Farouc Jaffer, Milind Rajopadhye
