摘要： Devices and methods for providing access to the pericardial cavity while reducing risk of myocardial damage including advancing a puncture device towards a heart, the puncture device including an energy delivery device at a distal end of the puncture device; delivering a single pulse of a pulsed energy through the energy delivery device to a parietal pericardium of the heart to create a void relatively close to the energy delivery device while maintaining the distal end of the puncture device in a substantially stationary position relative to the parietal pericardium; advancing the puncture device a short distance into the void; checking if the puncture device has accessed the pericardial cavity by measuring pressure on the distal end of the puncture device; and repeating, if necessary, until the energy delivery device is located at least partially within the pericardial cavity.

摘要： A medical device can include an elongate member, an irrigation port at a proximal end of the elongate member, and a resection assembly. The elongate member defines a first track and a second track. The resection assembly extends from a distal end of the elongate member and has a first member, a second member, and an electrically activatable resection element extending from a distal end of the first member. The first member includes a first portion located along the first track. The second member has a first portion located along the second track and the second member includes a longitudinally axial fluid conduit passageway. The passageway is in fluid communication with the irrigation port.

摘要： A depth sensing dilator system for dilating a penetration in a tissue plane includes an elongate flexible body, having a proximal end and a distal end. The body has a tapered dilator segment, and at least a first electrode on a distal end of the body. The system includes a processor and a user interface output device. The processor is configured to send a first signal to the output device when a change in impedance at the first electrode indicates that the first electrode has reached a predetermined relationship with the tissue plane.

摘要： A steerable, or curveable, introducer drill to access a target treatment region within bone along a curved trajectory is disclosed. The drill may include a drive shaft including a proximal rotational member, a distal drill tip, and an elongate shaft portion extending from the proximal rotational member to the distal drill tip. The distal drill tip may be sharp and include cutting flutes. The drill may also include an outer tube surrounding the drive shaft. A distal end portion of the outer tube may include a segmented tube section configured to facilitate controlled bending of the segmented tube section of the outer tube. The drill may also include an actuator operably coupled to the drive shaft and adapted to apply tension to the drive shaft which, in turn, causes the segmented tube section of the outer tube to bend.
