    摘要： An apparatus includes an elongate body and an expandable member coupled to the elongate body. In one embodiment, the expandable member has a collapsed configuration, an unfolded configuration and an expanded configuration. The expandable member is configured to be percutaneously inserted into an interior portion of a bone structure when the expandable member is in the collapsed configuration. The expandable member is configured to exert a pressure in a vertical direction on a first portion of the bone structure in contact with the expandable member greater than a pressure exerted in a lateral direction on a second portion of the bone structure in contact with the expandable member when the expandable member transitions from the unfolded configuration to the expanded configuration.

    摘要： In one embodiment, an apparatus includes a probe configured to be percutaneously deployed within an interior portion of a bone structure. At least a portion of the probe is configured to contact a portion of the interior portion of the bone structure when the probe is actuated within the interior portion of the bone structure. The apparatus also includes a pressure indicator that is configured to provide pressure data associated with a pressure externally exerted on the probe when the probe is actuated within the interior portion of the bone structure. In some embodiments, the probe includes an expandable member. In some embodiments, the probe includes an expandable low-compliance balloon.

    摘要： In one embodiment, an apparatus includes an elongate body and an expandable member coupled to the elongate body. The expandable member is configured to be disposed within an interior of a vertebral body having a first portion that includes cancellous bone and having a second portion that includes sclerotic bone distinct from an endplate of the vertebral body. The expandable member is configured to exert a first pressure on the first portion of the vertebral body and a second pressure different from the first pressure on the second portion of the vertebral body. The second pressure is sufficient to move the second portion of the vertebral body in a direction away from the expandable member when the expandable member is expanded within the interior of the vertebral body.

    摘要： 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.

    摘要： 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.
