Patent number: 10335590Abstract: A lead for an implanted medical device is disclosed in which the lead is adapted for electrical communication with an electrical signal source and has a distal tip with an electrode. The lead comprises a wire adapted to be placed in electrical communication with electrode. The wire includes: (i) a core comprising a polymeric material, and (ii) a metallic layer surrounding an outer surface of the core. The metallic layer includes a first section having a first thickness and a second section having a second thickness, wherein the first thickness is greater than the second thickness. The lead is substantially transparent to radio frequency waves in clinically-applicable magnetic resonance environments to reduce radio frequency absorption and avoid substantial heating effects.Type: GrantFiled: September 10, 2015Date of Patent: July 2, 2019Assignee: The General Hospital CorporationInventors: Husam Katnani, Giorgio Bonmassar

Patent number: 10327701Abstract: Methods, systems and arrangements are provided for obtaining electroencephalograph (“EEG”) EEG signals from a patient e.g., during a concurrent EEG/MRI examination of the patient. The methods, systems and arrangements include a cap made of conductive inks with sensor positions for attaching a plurality of sensors to the patient's head. The sensors can include electrodes as well as motion sensors for improving EEG signal quality and MRI image quality in the presence of motion noise and other artifacts within the MRI environment. The electrodes may be composed of conductive inks, and can be used in high magnetic fields due to a weak interaction with the RF fields generated by the MRI scanner. The exemplary methods, systems and arrangements can achieve lower SAR and lower temperature increase, as compared to conventional electrodes.Type: GrantFiled: November 21, 2005Date of Patent: June 25, 2019Assignee: The General Hospital CorporationInventors: Giorgio Bonmassar, Patrick L.

Patent number: 9579028Abstract: A system for detecting abnormalities or inconsistencies and a method to utilize the same are provided. In particular, a computer system may be adapted to detect the abnormality or inconsistency within at least a portion of a subject by generating internal impedance data which indicates that an impedance change within the portion of the subject has occurred. For example, the impedance change may be associated with a change in at least one characteristic of a blood vessel within the subject (such as a change in a fluid flow rate within at least a portion of the subject), a change in a fluid volume within at least a portion of the subject, etc. The impedance change also may be associated with the presence of a foreign object within the portion of the subject. In an exemplary embodiment, it is possible to detect the abnormality or inconsistency within the subject by generating a continuous, real time internal impedance map indicating the impedance change within the subject.Type: GrantFiled: June 9, 2011Date of Patent: February 28, 2017Assignee: The General Hospital CorporationInventors: Giorgio Bonmassar, John William Belliveau
