    Abstract: Systems (10) for examining heart tissue morphology deploy one or more electrodes (38) into the heart in contact with endocardial tissue. The systems transmit electrical current from the electrodes (38) in paths through the contacted endocardial tissue. Based upon these current transmissions, the systems derive the electrical characteristics of tissue lying in the path. This electrical characteristc can be directly correlated to tissue morphology. The systems maximize surface contact with endocardial tissue, while minimizing contact with the surrounding blood pool, to obtain accurate tissue electrical characteristic measurements.

    Abstract translation: 用于检查心脏组织形态的系统（10）将一个或多个电极（38）部署到与心内膜组织接触的心脏中。 该系统在通过所接触的心内膜组织的路径中从电极（38）传输电流。 基于这些当前传输，系统导出位于路径中的组织的电特性。 这种电学特征可以直接与组织形态相关。 系统最大限度地与心内膜组织的表面接触，同时最小化与周围血液池的接触，以获得精确的组织电特征测量。

    Abstract: This invention is a multiple electrode array for ablating tissue that carries at least two electrode segments (26, 27, 28, 29) that are circumferentially spaced form each other. Insulation (30) electrically isolates the separated electrode segments from each other. Signal wires (19) attached to the separated electrode segments convey ablating energy independently to the separated electrode segments. Because of its segmented structure, the array can place only one of the electrode segments in contact with tissue at one time. Because each segment is electrically isolated, and because each segment is independently served by its own signal wire, a physician can operate an ablation energy generator to selectively channel the ablation energy only to the segment actually contacting the tissue.

    Abstract translation: 本发明是一种用于烧伤组织的多电极阵列，其携带彼此周向隔开的至少两个电极段（26,27,28,29）。 绝缘（30）将分离的电极段彼此电隔离。 附接到分离的电极段的信号线（19）独立地传送消融能量到分离的电极段。 由于其分段结构，阵列可以一次只能将一个电极段与组织接触。 因为每个段都是电隔离的，并且由于每个段由其自己的信号线独立地服务，所以医师可以操作消融能量发生器来选择性地将消融能量传送到实际接触组织的区段。

    Abstract: An electrode circuit (34) has a distal region (32) for carrying at least one electrode, a proximal region (30) for connection to an external apparatus, and an intermediate region electrically coupling the distal region with the proximal region. At least one, and preferably all, of the regions comprises a flexible ribbon cable having two or more adjacent tracks (T1-T6) of electrical conduction material and adjoining electrical insulating material. Use of ribbon cable makes possible reliable connections without the need for complicated multiplexing schemes at the distal region.

    Abstract: A flexible electrode circuit (30) laces through a slit sleeve (W1, W8) while enclosing the rest of the circuit within the sleeve (98). A stiffener member (22) extends through the sleeve (98) to support the sleeve (98) and the flexible electrode circuit (30). The stiffener member (22) is preferably connected to and constrained at opposite ends by a hub (48) and a base (64) to urge the stiffener member (22), the sleeve (98), and the electrode circuit (30) into a predetermined curvilinear contour.

    Abstract: A steerable antenna assembly (14) employs a coaxial cable having a proximal region (50) for connection to a source of energy and a distal region (16) for propagating the energy. The coaxial cable also has an intermediate region (32) between the distal and proximal regions that has a greater degree of flexibility than the proximal region. A steering mechanism (10) is connected directly to the intermediate region (32) of the coaxial cable for bending the intermediate region (32) and, with it, the distal energy propagation region of the coaxial cable relative to its proximal region.
