Patent number: 9867869Abstract: Compounds, compositions, and methods for “smart” delivery of a therapeutic, prophylactic or diagnostic agent, such as glucose-mediated delivery of insulin through glucose-sensing insulin derivatives, are provided. The insulin derivatives bind serum albumin or agglomerate in vivo. The insulin derivatives effectively dissociate to release insulin in a hyperglycemic condition, where the complexation of glucose to a glucose-sensing element alters properties of the insulin derivative leading to the dissociation. The compounds, compositions, and methods provide a delivery strategy for both self-regulated and long-term diabetes management.Type: GrantFiled: December 12, 2013Date of Patent: January 16, 2018Assignees: Massachusetts Institute of Technology, The Children's Medical Center CorporationInventors: Daniel G. Anderson, Hung-Chieh Chou, Michael J. Webber, Benjamin C. Tang, Yair Levi, Yunlong Zhang, Rosemary Lynn Kanasty, Arturo Jose Vegas, Robert S. Langer

Patent number: 9839781Abstract: A system to measure intracardiac impedance includes implantable electrodes and a medical device. The electrodes sense electrical signals of a heart of a subject. The medical device includes a cardiac signal sensing circuit coupled to the implantable electrodes, an impedance measurement circuit coupled to the same or different implantable electrodes, and a controller circuit coupled to the cardiac signal sensing circuit and the impedance measurement circuit. The cardiac signal sensing circuit provides a sensed cardiac signal. The impedance measurement circuit senses intracardiac impedance between the electrodes to obtain an intracardiac impedance signal. The controller circuit determines cardiac cycles of the subject using the sensed cardiac signal, and detects tachyarrhythmia using cardiac-cycle to cardiac-cycle changes in a plurality of intracardiac impedance parameters obtained from the intracardiac impedance signal.Type: GrantFiled: May 7, 2013Date of Patent: December 12, 2017Assignee: Cardiac Pacemakers, Inc.Inventors: Yunlong Zhang, James O.
