    摘要： Ablation systems comprise a support body, an energy transmitting element supported by the support body and an insulating member covering a portion of the support body and energy transmitting member. Ablation energy is transmitted from an uncovered, exposed portion of the energy transmitting element. The insulating member may be a distal portion of an introducer sheath. An open segment may be provided in the distal portion to expose a portion of the energy transmitting element. When used in cardiac ablation therapy, for example, the insulating member decreases the amount of ablation energy dissipated in the blood circulating through the heart and thermally insulates the energy transmitting member and the tissue at the ablation site, enabling better control of the ablation process. An inflatable balloon or an expandable web may be provided coupled to the distal portion of the sheath behind the open segment to provide further insulation of the energy transmitting element and of the tissue around the ablation site. In another embodiment, ablation catheters incorporate an insulating member such as the inflatable balloon, expandable web or a cover. Methods of ablating tissue are also disclosed.

    摘要翻译： 消融系统包括支撑体，由支撑体支撑的能量传递元件和覆盖支撑体的一部分和能量传递构件的绝缘构件。 消融能量从能量传递元件的未覆盖的暴露部分传输。 绝缘构件可以是引导器护套的远端部分。 可以在远端部分设置开放的段，以暴露能量传递元件的一部分。 当用于心脏消融治疗时，例如，绝缘构件减少在通过心脏循环的血液中消散的消融能量的量，并使能量传递构件和组织在消融部位热绝缘，从而能够更好地控制消融过程。 可以提供可充气气囊或可膨胀腹板，其联接到开放区段后面的护套的远端部分，以提供能量传递元件和围绕消融部位的组织的进一步绝缘。 在另一个实施例中，消融导管包括绝缘构件，例如可充气气囊，可膨胀腹板或盖。 还公开了消融组织的方法。

    摘要： Invasive medical catheters with distal end assemblies having a protective surface coating bonded thereto are constructed by applying a hydrophilic primer to at least a portion of a tubular polymer body. The primer coating chemically bonds to the polymer substrate by developing covalent bonding or cross linking with the substrate. A plurality of printed electrode elements are then formed on the polymer body, e.g., by a pad printing process. Once the primer coating is bonded to the polymer body, the assembly is coated with a regenerated cellulose layer, e.g., by a viscose process well known in the art. The primer coating, already bonded to the catheter body, is then bonded with the regenerated cellulose at an elevated temperature. After curing, the polymer body, primer coating and regenerated cellulose layer become a single composite material, thereby preventing the regenerated cellulose coating from any movement relative to the polymer body, and providing a secure protective layer over the electrodes.
