摘要： An instrument assesses the transmurality of an ablation lesion from a first surface of a targeted biological tissue to an opposed second surface thereof. The instrument includes at least a first electrode operably attached to an ablation instrument adapted to engage a tissue first surface, and at least a second electrode adapted to engage a tissue second surface, the at least second electrode positioned generally opposed to the at least first electrode. Alternatively, the at least second electrode may be adapted to be placed within a chamber of an organ. These electrodes facilitate measuring at least one of conduction time, conduction velocity, phase angle, and impedance through at least a portion of the targeted tissue to determine the transmurality of the ablation lesion.

摘要： An instrument is provided to assess the transmurality of an ablation lesion from a first surface of a targeted biological tissue to an opposed second surface thereof. The instrument includes a needle member having an elongated shaft and a distal tip portion adapted to pierce the tissue first surface and into the ablation lesion of the biological tissue. A plurality of needle electrodes are spaced-apart along the elongated shaft. When the needle member pierces the tissue first surface, each the electrode being positioned at different respective depths of the biological tissue from the tissue first surface to the tissue second surface. These electrodes each measure at least one of conduction time, conduction velocity, phase angle, and impedance through at least a portion of the targeted tissue and at the respective depth to determine the transmurality of the ablation lesion.

摘要： An ablation system incorporating an enhanced deflectable distal portion, is provided. The system includes an elongated tubular member having a deflectable distal portion adapted to assume a specific predetermined or predefined shape when deployed. The predetermined shape allows for the creation of a desired uniform energy emission pattern with respect to a target tissue, such that energy may be directed toward the target tissue independent of an approach orientation of the ablation system. The energy pattern results in the creation of a desired tissue ablation. The ablation system may further comprise a steering system which aides in directing the distal portion toward a target tissue site. The steering system may alternatively be incorporated into a separate guiding catheter as part of the ablation system.

摘要： A flexible microwave antenna assembly for a surgical ablation instrument is capable of conforming to a tissue surface for ablation thereof. The ablation instrument includes a transmission line having a proximal portion suitable for connection to an electromagnetic energy source, and includes a flexible antenna coupled to the transmission line for radially generating an electric field sufficiently strong to cause tissue ablation. A flexible shield device is coupled to the antenna to substantially shield a surrounding area of the antenna from the electric field radially generated therefrom while permitting a majority of the field to be directed generally in a predetermined direction. A flexible insulator is disposed between the shield device and the antenna to define a window portion enabling the transmission of the directed electric field in the predetermined direction. The antenna, the shield device and the insulator are formed for selective manipulative bending thereof, as a unit, into contact positions that generally conform the window portion to the biological tissue surface to be ablated.

摘要： A catheter system with an enhanced steering system, allowing for positioning the distal portion of the catheter proximate to a desired biological target tissue site, is provided. The system includes an elongated tubular member having a steerable distal end configured to deflect, or otherwise direct, and properly position at least a portion of the distal end comprising an ablation device during a surgical procedure allowing for the placement of the deflected portion adjacent or proximate to the target tissue surface. The steering system may alternatively be incorporated into a separate guiding catheter as part of the catheter system.
