摘要： A medical manipulation assembly includes a catheter and distal and proximal steering mechanisms. The catheter includes distal and proximal steerable portions with working channels configured to receive an instrument. The distal steering mechanism is operable to bend the distal steerable portion in a first plane relative to the proximal steerable portion in response to movement of a first portion of the distal steering mechanism about a first axis of rotation and to bend the distal steerable portion in a second plane relative to the proximal steerable portion in response to movement of a second portion of the distal steering mechanism about a second axis of rotation. The proximal steering mechanism is operable to bend the proximal steerable portion by rotational movement of the proximal steering mechanism. Distal pullwires extend between the distal steerable portion and steering mechanism and proximal pullwires extend between the proximal steerable portion and steering mechanism.

摘要： A method of ablating a tissue region within a blood-filled environment comprises restraining a fluid within a visualization field in a portion of the blood-filled environment and visualizing the tissue region through the fluid within the visualization field. The method also includes transmitting ablating electrical energy from the fluid into the visualized tissue region.

摘要： A medical manipulation assembly comprises a catheter including distal and proximal steerable portions with working channels. The assembly further comprises a steerable sheath through which the steerable portions extend. A distal steering mechanism, including a first lumen extending along a longitudinal axis of the catheter, bends the distal steerable portion. A proximal steering mechanism, including a second lumen extending along the axis and defined by a wall, bends the proximal steerable portion by rotational movement of the proximal steering mechanism independently of the distal steerable portion. The wall is rotatable about the axis. Distal pullwires extend between the distal steerable portion and the distal steering mechanism. Proximal pullwires extend between the proximal steerable portion and the proximal steering mechanism. The second lumen is axially aligned with an access lumen extending proximally from the proximal steering mechanism through which the distal and proximal working channels may receive a visualization instrument.

摘要： An apparatus may be used for ablating a target tissue region disposed along a tissue surface. The apparatus may comprise a means for directing ablating energy into the target tissue region through the tissue surface and a means for imaging the tissue surface along the target tissue region while selectively directing the ablating energy. The imaging means may be coupled to the energy directing means.

摘要： A computer implemented method comprises receiving a model of a tissue region, steering a distal end of a catheter within a body to a first area of a tissue region, and obtaining a first image from the distal end of the catheter of the first area of the tissue region. The method further comprises mapping the first image of the first area of the tissue region to the model of the tissue region and displaying the first image of the first area of the tissue region on the model of the tissue region.

摘要： A computer implemented method comprises activating a control mechanism on a catheter handle in a first direction with respect to a user to steer a distal end of a catheter within a body in a second direction while the catheter handle is in a first rotational position. The control mechanism includes a first indicator associated with the first direction. The computer implemented method also includes obtaining an image from the distal end of the catheter of a tissue region of interest within the body and calibrating a first rotational motion of the catheter handle with a rotational motion of the image. With the catheter handle in a second rotational position that is different than the first rotational position, the control mechanism activated in the first direction with respect to the user moves the distal end of the catheter in the second direction.

摘要： A medical manipulation assembly comprises an elongated distal steerable portion with a distal working channel extending through the elongated distal steerable portion. The assembly also comprises an elongated proximal steerable portion arranged proximally of the elongated distal assembly portion. A proximal working channel extends through the elongated proximal steerable portion. The assembly also comprises a distal steering mechanism to bend the distal steerable portion in response to movement of the distal steering mechanism. The assembly also comprises a proximal steering mechanism to bend the proximal steerable portion, independently of the distal steerable portion, in response to rotational movement of the proximal steering mechanism. The assembly also comprises distal pullwire(s) extending between the elongated distal steerable portion and the distal steering mechanism and proximal pullwire(s) extending between the elongated proximal steerable portion and the proximal steering mechanism. The distal and proximal portion working channels are configured to receive a visualization instrument.

摘要： In vivo visualization systems are described which facilitate tissue treatment by a user in utilizing real time visualized tissue images with generated three-dimensional models of the tissue region of interest, such as the left atrial chamber of a subject's heart. Directional indicators on the visualized tissue as well as the imaging systems may be utilized while other variations may utilize image rotation or manipulation of visualized tissue regions to facilitate catheter control. Moreover, visualized tissue regions may be combined with imaged tissue regions as well as navigational information to further facilitate tissue treatments.
