Atherectomy catheter with shapeable distal tip

An atherectomy catheter for use in a vessel includes an elongate catheter body and an annular cutter. The elongate catheter body includes a fixed jog section with a pre-set curvature and a flexible section that has a greater flexibility than a remainder of the elongate catheter body. The fixed jog section and flexible section are formed of a frame including a plurality of circumferential slits therein. Also described herein is an atherectomy catheter for use in a vessel includes an elongate catheter body, an annular cutter, and an s-shaped curved portion in the elongate catheter body. The curved portion includes a frame having a longitudinal proximal spine and a longitudinal distal spine. The longitudinal proximal spine is positioned approximately 180 degrees away from the longitudinal distal spine.

MALLEABLE SUCTION INSTRUMENT WITH OFFSET POSITION SENSOR

An apparatus such as a suction instrument includes a position sensor proximate to a distal tip of a malleable shaft. A sensor wire couples the position sensor to a processor of an image guided surgery system such that signals generated by the position sensor can be interpreted to determine the position of the surgical instrument. The malleable shaft includes a malleable outer shaft and a flexible inner tube. The flexible inner tube includes a primary lumen that can provide suction, fluid, or various deployable surgical tools, and an inner lumen that holds the sensor wire. Protected within the inner lumen, the sensor wire runs the length of the shaft and exits the inner lumen and passes through a slot in the outer shaft to reach the position sensor. A heat shrink cover wraps the distal tip, sealing the components together and providing an opening suitable for suction.

11172973 · 2021-11-16 · ·

An intramedullary pin includes a main body having a proximal boundary and a distal boundary; a curved extension having a degree of curvature of at least 1°, the curved extension being in direct contact with the distal boundary; a distal cap having a cylindrical portion and a rounded portion, the cylindrical portion being in direct contact with the curved extension; a grip element having at least one contour, the grip element being in direct contact with the proximal boundary; and a proximal cap having a flat surface, the proximal cap being in direct contact with the grip element. Also disclosed is a clamp that includes a handle, two blades, a pivot, and a plurality of grasping elements including a notch, at least one protrusion, and a groove, where one or more grasping elements have a contour that is structurally complementary to the grip element in the intramedullary pin. A method of immobilizing a bone fracture using the intramedullary pin and/or clamp is also disclosed.

COMBINATION ULTRASONIC AND ELECTROSURGICAL INSTRUMENT HAVING CURVED ULTRASONIC BLADE
20210346078 · 2021-11-11 ·

A surgical instrument includes an ultrasonic transducer, a shaft defining a longitudinal axis, and an end effector at a distal end of the shaft. The end effector includes an ultrasonic blade driven by the ultrasonic transducer to treat tissue with ultrasonic energy. A tissue treatment portion of the ultrasonic blade includes a linear blade region extending parallel to the longitudinal axis, a curved blade region extending distally from the linear blade region along a curved path that deflects laterally from the longitudinal axis, an upper treatment side, a lower treatment side, a first lateral side having a first sweeping side surface, and a second lateral side having a second sweeping side surface. The sweeping side surfaces define respective first and second side edges of a transverse cross-section of the tissue treatment portion, and are configured such that the first and second side edges are parallel to one another.

Device for use in hysteroscopy

A device for visualization of internal tissue of a patient's uterus having a hand-held control unit, an elongated member, and an image capturing tip. To increase the manoeuvrability of the image capturing tip, the elongated member forms a straight portion extending along a straight axis and a curved portion forming a curvature away from the straight axis, the curved portion being between the image capturing tip and the straight portion. By rotation of an inner tube in an outer tube, the image capturing structure will move along a circular path without being rotated about the centre axis of the elongated member.
