Abstract
The present technology relates to steerable catheters that can include an indicator assembly for providing an indication to a user of a direction and/or magnitude of steering of the catheter shaft including various components of the indicator assembly and handle of the catheter shaft. In certain examples, steerable catheters may include a tensioning mechanical for pull-wires and pressure sensors.
Claims20
A steerable catheter, comprising:
- a handle assembly comprising a handle shell and a steering mechanism;
- and
- an elongate sheath extending distally from the handle assembly;
- wherein the steering mechanism includes an axial translation mechanism coupled to a first steering wire extending within the elongate sheath and a second steering wire extending within the elongate sheath;
- wherein the first steering wire is configured to cooperate with the axial translation mechanism to bend a distal portion of the elongate sheath in a first direction;
- wherein the second steering wire is configured to cooperate with the axial translation mechanism to bend the distal portion of the elongate sheath in a second direction opposite the first direction;
- wherein the handle assembly comprises a non-visual torque indicator configured to convey a rotational position of the handle assembly relative to a neutral position.

A steerable catheter, comprising:
- a handle assembly comprising a handle shell and a steering mechanism;
- and
- an elongate sheath extending distally from the handle assembly;
- wherein the steering mechanism includes an axial translation mechanism;
- wherein a first steering wire extends distally from the axial translation mechanism to a distal pull ring disposed within the elongate sheath;
- wherein a second steering wire extends distally from the axial translation mechanism to the distal pull ring, the second steering wire being disposed on an opposite side of the elongate sheath from the first steering wire relative to a central longitudinal axis of the elongate sheath;
- wherein the first steering wire is configured to cooperate with the axial translation mechanism to bend a distal portion of the elongate sheath in a first direction;
- wherein the second steering wire is configured to cooperate with the axial translation mechanism to bend the distal portion of the elongate sheath in a second direction opposite the first direction;
- wherein the handle assembly comprises a non-visual torque indicator configured to convey a rotational position of the handle assembly relative to a neutral position.
