摘要:
One focal ablation assembly (72), used with an endoscope (12) comprising an endoscopic tube (16), comprises a cryogenic catheter (26), a balloon (74) and a reinforcing element (88). The cryogenic catheter is placeable within the endoscopic tube channel (28) and has a distal end (34) placeable at the distal end (24) of the endoscopic tube. The balloon is mountable to the catheter distal end (34) and extends distally of both of the distal ends. The reinforcing element at least partially defines the shape of the balloon in the expanded state. The balloon has a thermally conductive therapeutic region (36) which provides effectively no thermal insulation. Another focal ablation assembly (14) uses a cap (22) instead of the balloon. The cap substantially maintains its shape during use while not causing tissue trauma.

与包括内窥镜管(16)的内窥镜(12)一起使用的一个局部消融组件(72)包括低温导管(26),球囊(74)和加强元件(88)。 低温导管可放置在内窥镜管通道(28)内,并且具有可置于内窥镜管的远端(24)处的远端(34)。 气囊可安装到导管远端(34)并且延伸到两个远端的远侧。 增强元件至少部分地限定膨胀状态下的球囊的形状。 球囊具有导热治疗区域(36),其有效地提供绝热。 另一个焦点消融组件(14)使用盖(22)代替气球。 帽子在使用过程中基本保持其形状,同时不会导致组织创伤。
