Patent number: 9839408Abstract: Minimally invasive systems and methods are described for measuring pulmonary circulation information from the pulmonary arteries. A transbronchial Doppler ultrasound catheter is advanced through the airways and in the vicinity of the pulmonary artery. Doppler ultrasound energy is sent through the airway wall and across the pulmonary artery to obtain velocity information of blood flowing through the artery. The velocity information is used to compute pulmonary circulation information including but not limited to flowrate.Type: GrantFiled: August 10, 2012Date of Patent: December 12, 2017Assignee: PneumRx, Inc.Inventors: Edmund J. Roschak, Jeffrey Schwardt, Philip Stephen Levin

Publication number: 20160008038Abstract: Methods, apparatus and systems for constraining spinous processes to elastically limit flexion of two or more adjacent spinal segments rely on placing a tether structure over at least three adjacent vertebral bodies or two adjacent vertebral bodies and the sacrum. The tether structures may be continuous, for example in the form of a continuous loop, or may be discontinuous, for example in the form of a loop or elongate element having at least two anchor structures for securing in bone.Type: ApplicationFiled: March 30, 2015Publication date: January 14, 2016Inventors: Todd Alamin, Ian Bennett, Louis Fielding, Colin Cahill, Jeffrey Schwardt

Publication number: 20130325065Abstract: A system for fusing a spine comprises a flexion limiting tether having a superior portion, and an inferior portion. The superior portion of the device is coupled to a superior portion of the spine, and the inferior portion of the device is coupled to an inferior portion of the spine thereby constraining flexion of the spine. The system also includes bone graft for fusing the superior and inferior portions of the spine together. The bone graft is disposed between the superior and inferior portions of the spine, and the tether has a width suitable for holding the bone graft in a mass disposed between the superior and inferior portions of the spine. The tether also has a porosity suitable to allow body fluids to pass therethrough so that the graft material forms a solid mass.Type: ApplicationFiled: August 9, 2013Publication date: December 5, 2013Applicant: Simpirica Spine, Inc.Inventors: Hugues Malandain, Jeffrey Schwardt, Austin F. Noll, III, Ian Bennett, Louis Fielding

Publication number: 20070060935Abstract: In one embodiment, an apparatus includes a cannula configured to provide percutaneous access to a nucleus of an intervertebral disc, and an elongate body configured to be movably disposed within a lumen of the cannula. The cannula also defines an opening. The elongate body defines an internal passageway and an opening at a distal portion of the elongate body. The internal passageway of the elongate body can be coupled to a suction source. The elongate body has a cutting portion disposed on an edge of the opening of the elongate body and the elongate body is configured to draw a portion of tissue from within the nucleus of the intervertebral disc into the opening of the elongate body when the suction source is activated. The cutting portion is configured to sever the portion of tissue from the remaining tissue when the elongate body is moved relative to the cannula.Type: ApplicationFiled: June 12, 2006Publication date: March 15, 2007Inventors: Jeffrey Schwardt, Alberto Cantu, Erika Palmer
