20090131765 | METHOD AND SYSTEM FOR MEASURING PULMONARY ARTERY CIRCULATION INFORMATION - 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. | 05-21-2009 |
20100312141 | TISSUE SAMPLING DEVICES, SYSTEMS AND METHODS - Methods, devices, and systems are described herein that allow for improved sampling of tissue from remote sites in the body. A tissue sampling device comprises a handle allowing single hand operation. In one variation the tissue sampling device includes a blood vessel scanning means and tissue coring means to excise a histology sample from a target site free of blood vessels. The sampling device also includes an adjustable stop to control the depth of a needle penetration. The sampling device may be used through a working channel of a bronchoscope. | 12-09-2010 |
20120165872 | METHODS AND SYSTEMS FOR CONSTRAINT OF MULTIPLE SPINE SEGMENTS - 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. | 06-28-2012 |
20120265249 | DEVICE AND ACCESSORIES FOR LIMITING FLEXION - A device may be used to limit flexion of the spine without substantially limiting extension of the spine. Various accessories, instruments, and methods may be used to help deploy the flexion limiting device, manipulate, and adjust it. | 10-18-2012 |
20130184579 | Method and System for Measuring Pulmonary Artery Circulation Information - Minimally invasive systems and methods are described for measuring pulmonary circulation information from the pulmonary arteries.

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. | 07-18-2013 |
20130253584 | METHODS AND SYSTEMS FOR LATERALLY STABILIZED CONSTRAINT OF SPINOUS PROCESSES - A spinal implant for limiting flexion of the spine includes a tether structure for encircling adjacent spinal processes. Usually, a pair of compliance members will be provided as part of the tether structure for elastically limiting flexion while permitting an extension. A cross-member is provided between the compliance member or other portions of the tether structure to stabilize the tether structure and prevent misalignment after implantation. | 09-26-2013 |
20130325065 | SPINOUS PROCESS CERCLAGE FOR BONE GRAFT CONTAINMENT - 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. | 12-05-2013 |
