摘要： An elongated support assembly is positionable, at least in part, in sliding relationship with an elongated flexible medical assembly. The elongated support assembly is configured to support, at least in part, the elongated flexible medical assembly after the elongated support assembly is positioned, at least in part, in sliding relationship with the elongated flexible medical assembly. The elongated support assembly is, at least in part, selectively maneuverable via an elongated ancillary medical assembly toward a distal portion of the elongated ancillary medical assembly.

摘要： For robotically operating a catheter, a medical catheter is controlled by rotation of the catheter as well as steering in one or more planes of a distal end of the catheter. To robotically rotate the catheter, a handle is rotated. The steering is performed separately using one or more knobs on the handle. The rotation of the handle complicates the robotic control of the knob. A mechanical decoupling is used so that rotation of the handle maintains the position of the knob relative to the handle. Gearing or transmission is used to avoid independent control of the knob and handle rotation. In an alternative or additional approach, the handle may be robotically controlled while also guiding the catheter shaft spaced away from the handle, allowing fine-tuned control of the catheter at the access point to the patient.

摘要： The disclosure provides a flexible, narrow medical device (such as a micro-catheter or a guidewire) that is controllably moved and steered through lumens of a body. The medical device may include an electrically-actuatable bendable portion at a distal end, which may be provided by a polymer electrolyte layer, electrodes distributed about the polymer electrolyte layer, and electrical conduits coupled to the electrodes, such that the polymer electrolyte layer deforms asymmetrically in response to an electrical signal through one or more conduits. The disclosure further includes a controller for moving the device into and out of bodily lumens and for applying the electrical signal for steering the device. The device further includes methods of preparing the polymer electrolyte layer in tubular shape.

摘要： An apparatus and method of manufacture includes a helical wire coil body having a proximal body end portion and a distal body end portion that extend along a longitudinal coil axis. The apparatus also includes a non-extensible, core wire assembly configured to inhibit longitudinal elongation of the helical wire coil body along the longitudinal coil axis. The core wire assembly has a first core wire and a second core wire respectively extending from the proximal body end portion toward the distal body end portion. The second core wire proximally terminates relative to the first core wire such that the distal body end portion is more flexible than the proximal body end portion. The first and second core wires transversely overlap to provide a collective column strength to the helical wire coil body along the longitudinal coil axis.

摘要： A catheter movement control device and packaged catheter equipped with the catheter movement control device. The catheter movement control device includes a main body defining a passageway and a locking member with an oblong orifice hingedly attached to the main body. The locking member pivots about a pivot axis and is rotationally secured to the main body so that the major axis of the oblong orifice is fixedly oriented nearly parallel with the pivot axis. The locking member is pivotable about the pivot axis relative to the main body as between a first position wherein the orifice is aligned with the passageway, and a second position wherein the orifice is misaligned with the passageway.

摘要： The invention relates to a catheter device, having a catheter (1), an actuation device (8) at a first end of the catheter and also a mechanical transmission element (9, 10) for transmitting a movement along the catheter to the actuation device, the actuation device having a coupling element (14) which is connected to the transmission element (9, 10) and can be actuated by the latter relative to the longitudinal direction of the catheter in a first degree of freedom, and also a conversion element (15) which can be actuated by the coupling element and which converts the actuation movement at least partially into a movement in a second degree of freedom. As a result, a combined movement at the distal end of the catheter can be produced particularly simply for compression and release of a functional element.

摘要： A robotic module for driving an elongate flexible medical member includes: movable drive members alternately positioned in a drive configuration in which the drive members are sufficiently close together to be able to drive the elongate flexible medical member, and in a free configuration in which the drive members are sufficiently far apart so as to no longer be able to drive the elongate flexible medical member, a control member controlling movement of the movable drive members into the drive configuration in which the elongate flexible medical member is driven, and a reverse movement into the free configuration, a stress sensor measuring stress on at least one of the drive members, and a user interface linked to the stress sensor so as to receive the measured stress from the stress sensor and suitable for providing a signal representative of the measured stress to the user of the robotic module.

摘要： A manipulator, including an elongated chassis containing a U-shaped channel defining a distal direction and a proximal direction. The manipulator also includes an adjuster that is configured to slide in the U-shaped channel. The adjuster includes a first wheel which on rotation translates a guidewire positioned in the adjuster along an axis of the guidewire, and a second wheel which on rotation rotates the guidewire positioned in the adjuster about the axis of the guidewire. The adjuster also includes a port, distal to the first and the second wheel, that is configured to accept a tubular balloon and the guidewire.
