An access tube is used for accessing an anatomic space, such as a pericardial space between the parietal and visceral pericardia. The access tube is advanced against the parietal pericardium and an anchor structure thereon embedded into the parietal pericardium. The access tube can then be used to separate the parietal and visceral pericardia and enlarge the pericardial space. After such enlargement, a needle or other access device can be introduced through the access tube into the pericardial space to provide access for a wide variety of purposes, including aspiration, infusion, and guidewire placement.

Methods and apparatus for pericardial access

An arrangement for monitoring the power delivered by a photon channeling element including an integrating chamber to receive an output end of the photon channeling element and an optical surface positioned to reflect a portion of the laser-light exiting the photon channeling element at substantially normal incidence to the beam centerline. The integrating chamber may be adapted to collect substantially all of the laser-light reflected from the optical surface. The arrangement may also include a sensor in optical contact with a portion of the integrating chamber that is out of the path of laser-light reflected from the optical surface.

Implantable systems for controlling flow through body lumens comprise a control module and an actuator. The actuator is implanted at least partially over the body lumen to selectively constrict the lumen and control flow therethrough. The control module includes at least a power source for operating the actuator and a remotely operated switch for controlling the power source. Usually, the control module will have programmable circuitry for adjusting on/off time, degree of closure, and the like. The switch of the control module is remotely actuated by a magnetic or other signal. The control circuitry may be remotely programmed using a hand-held programmer.
