摘要： A system and method for positioning a medical instrument at a desired biological target tissue site is provided. The system includes an elongated sheath having a deflectable distal end configured to deflect or otherwise position at least a portion of a medical instrument during a surgical procedure allowing for the placement of the deflected portion adjacent or proximate to a predetermined target tissue surface. The positioning system may be incorporated into the medical instrument. The medical instrument may be an ablation system.

摘要： A system and method for ablating a selected portion of a contact surface of biological tissue is provided. The system includes an elongated ablation sheath having a preformed shape adapted to substantially conform a predetermined surface thereof with the contact surface of the tissue. The ablation sheath defines an ablation lumen sized to slideably receive an elongated ablative device longitudinally therethrough. The ablative device includes a flexible ablation element selectively generating an ablative field sufficiently strong to cause tissue ablation. Advancement of the ablation element slideably through the ablation lumen of the ablation sheath selectively places the ablation element along the ablation path for guide ablation on the contact surface when the predetermined surface is in strategic contact therewith. The ablation lumen and the ablative device cooperate to position the ablation element proximate to the ablation sheath predetermined surface for selective ablation of the selected portion within the ablative field.
摘要翻译：提供了用于烧蚀生物组织的接触表面的选定部分的系统和方法。该系统包括具有适于基本上使其与组织的接触表面的预定表面一致的预成型形状的细长消融护套。消融套限定了消融腔，其大小可纵向滑动地容纳细长的消融装置。烧蚀装置包括柔性消融元件，其选择性地产生足够强以引起组织消融的烧蚀场。当消融元件可滑动地穿过消融鞘的消融腔时，推进消融元件选择性地将消融元件沿着烧蚀路径放置，以在预定表面与其接触时与接触表面进行引导消融。消融腔和消融装置配合以将消融元件靠近消融鞘预定表面定位，以在烧蚀区内选择性地烧蚀所选择的部分。

摘要： A system and method for ablating a selected portion of a contact surface of biological tissue is provided. The system includes an elongated ablation sheath having a preformed shape adapted to substantially conform a predetermined surface thereof with the contact surface of the tissue. The elongated ablation sheath includes a non-permeable portion. The ablation sheath defines an ablation lumen sized to slideably receive an elongated ablative device longitudinally therethrough. The ablative device includes a flexible ablation element selectively generating an ablative field sufficiently strong to cause tissue ablation. Advancement of the ablation element slideably through the ablation lumen of the ablation sheath selectively places the ablation element along the ablation path for guide ablation on the contact surface when the predetermined surface is in strategic contact therewith. The ablation lumen and the ablative device cooperate to position the ablation element proximate to the ablation sheath predetermined surface for selective ablation of the selected portion within the ablative field.
