Abstract: Apparatus for controlling motion of an invasive probe relative to a sheath enclosing the probe. The apparatus includes an outer casing, configured for connection to the sheath. The apparatus further includes a drive mechanism, fixedly connected to the outer casing. The drive mechanism has a first set of components, configured to translate the probe along a direction parallel to as axis of the probe, in order to advance and retract the probe with respect to the sheath in a translational stepwise manner. The drive mechanism also includes a second set of components, configured to rotate the probe around the axis of the probe, in order to rotate the probe clockwise and counter-clockwise, with respect to the sheath, in a rotational stepwise manner.

Abstract: The disclosed invention provides a handle for controlling movements of a transseptal insertion shaft which is suitable for facilitating precise and safe transseptal puncture of a cardiac interatrial septum, and a transseptal puncture system that include a transseptal insertion shaft and a handle to control movements of the transseptal insertion shaft. The handle includes two twister thread half shells, a nut inner and nut outer placed inside the two twister thread half shells, a first pull wire connected to a first side of the transseptal insertion shaft and coupled to the nut inner, a second pull wire connected to a second side of the transseptal insertion shaft and coupled to the nut outer. The nut inner and nut outer rotate in opposite directions to each other when the two twister thread half shells are turned in a direction.

Abstract: User interface devices, systems, and methods can be used for selectively bending of, altering the bend characteristics of, and/or altering the lengths of catheter bodies, guidewires, steerable trocars, and other flexible structures inserted into a patient during use. Optionally, a housing is coupled to a proximal end of a catheter, and movement of the housing by a hand of a system user is sensed and used as a movement command for articulation of the catheter. Alternatively, a sensor can be coupled to an elongate flexible body flexing outside of the patient so as to alter bending of a catheter within the patient. Movements generated through a combination of manual manipulation and powered articulations are facilitated.

Abstract: Deflectable guide catheters and methods, including methods for using deflectable guide catheters to perform transnasal procedures within the ear, nose, throat, paranasal sinuses or cranium. Some deflectable guide catheters of the present invention comprise a substantially rigid tube, a helical spring attached to and extending from the distal end of the substantially rigid tube, a tubular plastic inner jacket, an outer plastic jacket substantially covering at least the helical spring member. The spring member is deflectable to cause the distal portion of the guide catheter to deflect to a curved configuration. In embodiments for transnasal use the deflectable guide catheter may have a length of less than 25 cm.

Abstract: The present invention relates to a steerable catheter device and method of using the same comprising a catheter body having a distal section. The distal section of the catheter body has an inner lumen, and one or more steering lumen radially offset from the inner lumen. The steering lumen comprise a first end having a first diameter and a second end having a second diameter smaller than the first diameter. A fluid source is in fluid communication with the steering lumen for supplying fluid thereto to radially distend the first end of the steering lumen such that the catheter body bends away from the steering lumen. In some cases, a vacuum is supplied to an opposite lumen to further assist bending of the catheter body. The inner lumen may include a porous material that is utilized to clean an instrument, such as an imaging device, movably disposed in the inner lumen.
