Publication number: 20230270998Abstract: Endovascular lead design and delivery systems are described herein. One variation of an endovascular lead apparatus may generally comprise an elongate body having a proximal portion and a distal portion, one or more electrodes positioned along a first side of the distal portion, a tray positioned along a second side of the distal portion opposite to the first side, and one or more frame members positioned along the tray and which are reconfigurable from a low-profile delivery configuration to an expanded deployed configuration, wherein expansion of the one or more frame members to the expanded deployed configuration reconfigures the distal portion into contact against a tissue wall for energy delivery via the one or more electrodes.Type: ApplicationFiled: February 27, 2023Publication date: August 31, 2023Applicant: RMX, LLCInventors: Amir J.

Publication number: 20130197601Abstract: A device and method for treating a subject is provided where electrical stimulation may be separately provided to each hemidiaphragm to cause diaphragm contraction. Fatigue may be avoided among other possible benefits. Each hemidiaphragm may also be stimulated with different stimulation parameters. Stimulation may be smoothly transitioned between hemidiaphragms. Such stimulation may provide an increase in functional residual capacity or other therapeutic effects.Type: ApplicationFiled: January 11, 2013Publication date: August 1, 2013Applicant: RMX, LLCInventor: RMX, LLC

Patent number: 8467876Abstract: A device and method are provided for managing the treatment of a patient with respiratory disorders or symptoms. Respiratory parameters are sensed and recorded and communicated to an external device to provide information to a patient and/or provider for further treatment or diagnosis. Also respiratory disorders such as apnea or hypoventilation may be treated by electrically stimulating the diaphragm muscle or phrenic nerve in response to a sensed respiratory parameter or characteristic.Type: GrantFiled: October 15, 2003Date of Patent: June 18, 2013Assignee: RMX, LLCInventor: Amir J.
