Abstract: A thermal ablation device includes an elongated member sized and shaped for insertion into a uterus via a cervical opening. The elongated member defines a first lumen extending therethrough to a first distal opening which, when the apparatus is in an operative position, opens into the uterus and a seal positioned on the elongated member so that, when the elongated member is in the operative position, the seal engages cervical tissue around a circumference of the elongated member and prevent fluids introduced into the uterus via the first lumen from flowing therepast into the cervix. The seal includes a plurality of flexible members separated from one another along a length of the elongated member and projecting radially outward from an outer surface of the elongated member.

Abstract translation: 热消融装置包括细长构件，其尺寸和形状用于经由颈部开口插入子宫。 细长构件限定了延伸通过其延伸到第一远侧开口的第一腔，当第一远端开口处于操作位置时，第一内腔开口进入子宫，并将密封件定位在细长构件上，使得当细长构件处于操作位置时， 所述密封件使所述细长构件的圆周周围的子宫颈组织接合，并且防止经由所述第一腔引入到所述子宫中的流体流入所述子宫颈。 密封件包括沿着细长构件的长度彼此分离并从细长构件的外表面径向向外突出的多个柔性构件。

Abstract: A medical device may comprise a handle, which may include a grip portion; a body portion; and a ram housing extending proximally of the body portion; and a shaft having a first, proximal portion and a second, distal portion. The first portion of the shaft may include a first outer sheath. The second portion of the shaft may include a second outer sheath. The first outer sheath may be more rigid than the second outer sheath. The medical device may further comprise a rigid ram extending through at least a portion of the body portion and at least a portion of the shaft. The ram may be configured to be transitioned from a first, proximal configuration, in which the second portion of the shaft is flexible, and a second, distal configuration, in which the second portion of the shaft is rigid.
