摘要： Template systems and methods for various procedures (e.g., tissue ablation procedures) are disclosed. An exemplary template system (10) comprises a track (12) having at least one suction port (22). The at least one suction port (22) anchors the track (12) to a tissue after the track (12) is positioned adjacent a target area. The template system (10) may further comprise a transducer (14) operatively associated with the track (12). Exemplary transducers include imaging transducers and ablating transducers. The transducer (14) is guided by the track (12) adjacent the target area while the transducer (14) is moved along the track (12) for a procedure. One or more umbilical (16a, 16b) may provide a conduit to the track (12) and/or transducer (14) so that the template system (10) may be positioned in a patient's body (e.g., for a procedure on the patient's heart) and operated remotely by a physician or other user from outside of the patient's body.

摘要： An ultrasonic endovascular clearing device for use in a bodily lumen includes a powering handle configured to enclose one or more acoustic drivers (14), an acoustic amplifier and/or acoustic matching section including one or more amplifiers and/or matching elements (16) and a driven wire (18). The acoustic drivers (14) are configured to produce acoustic vibration in the ultrasonic frequency range. The amplifier/matching section (16) matches and amplifies the acoustic vibration and drives the wire (18) accordingly. The wire (18) cleans due to one or both of a) its asymmetric shape being driven, b) its feature-enhanced surface being driven, whether on an asymmetric wire or not. The driving is pulsed or continuous, cavitating or noncavitating, and torsional or radial/lateral in its possible operational embodiments. A drug may be used by or delivered by the device and wire/tissue parameter sensing is optionally provided.

摘要： A catheter for anchoring an electrode in a coronary sinus includes an elongate catheter body adapted to be inserted into a coronary sinus and at least one electrode on the catheter body. The elongate catheter body also includes at least one anchor movable between an undeployed configuration and a deployed configuration. When the anchor is in the undeployed configuration, the catheter may be introduced into and removed from the coronary sinus. When the anchor is in the deployed configuration, the anchor engages a tissue surface of the coronary sinus to inhibit movement between the catheter body and the coronary sinus, preferably without completely occluding the coronary sinus. The anchor may be a section of the catheter body having an expandable axial cross-section, an expandable member mounted on the catheter body, one or more wire anchors, or a flexible section of the catheter body.

摘要： A method of repairing a three dimensional surface mesh model to be watertight and manifold generally includes identifying a plurality of hole edges in the surface mesh model, selecting one of the hole edges, creating a cycle of hole edges that defines a hole in the surface mesh model, converting the cycle of hole edges into two or more cycles of exactly three edges each, and adding a triangular facet to the surface mesh model for each of the cycles of exactly three edges. The process may be repeated until the model is substantially watertight. Non-manifold vertices may be repaired by selecting a vertex of the model, identifying a number of independent cycles of triangular facets sharing the selected vertex, and redefining the selected vertex for at least all but one of the number of independent cycles. This process may be repeated until the model is manifold.

摘要： A wire lock includes a body having an opening therethrough, a locking member disposed at least partially within the opening, and a biasing device. The biasing device urges the locking member into a configuration wherein a wire passing through the opening is restrained in at least one direction, and may operate in either tension or compression. The locking member may include one or more locking elements that are compressed about the wire through engagement with a wedge-shaped locking section of the body, with the biasing member urging the locking member against the locking section. In other embodiments, the locking member is a locking pin riding on an inclined surface of an elongate slot extending across the body, with the biasing member urging the locking pin against one end of the slot, and the wire pinched between the pin and a body surface opposite the inclined surface.

摘要： A method of tracking a position of a catheter within a patient includes securing a navigational reference at a reference location within the patient, defining the reference location as the origin of a coordinate system, determining a location of an electrode moving within the patient relative to that coordinate system, monitoring for a dislodgement of the navigational reference from the initial reference location, for example by measuring the navigational reference relative to a far field reference outside the patient's body, and generating a signal indicating that the navigational reference has dislodged from the reference location. Upon dislodgement, a user may be provided with guidance to help reposition and secure the navigational reference to the initial reference location, or the navigational reference may be automatically repositioned and secured to the initial reference location. Alternatively, a reference adjustment may be calculated to compensate for the changed reference point/origin.
