A morselizer comprising (a) a hollow cylindrical structure with an inner wall and an outer wall and comprising a first end section, a second end section, and a center section extending axially between the first end section and the second end section providing a substantially axial liquid pathway therein; (b) wherein each end section comprises a axially and radially hollow luer fitting that is attachable to a structure with a complementarily sized luer fitting; and (c) one or more blades extending transversally across the inner diameter of the center section wherein (i) each blade is comprised of a plurality of ends, including a posterior end secured to at least the center wall section inner wall at a center section inner wall first position and an anterior end proximal a center section inner wall second position opposite the center section inner wall first position, with a gap positioned between the blade anterior end and the center section inner wall second position, and (ii) at least two ends comprise cutting ends.

A thrombectomy system includes a frame having plurality of struts joined at an apex, a netting coupled to the plurality of struts, a pestle moveable relative to the frame and configured and arranged to macerate a clot within a vessel, adherent to its walls and against a portion of the apex of the frame.

A method where a propeller is set into locomotion relative to a medium at least partially surrounding the propeller. An actuator induces a rotation of the propeller relative to the medium and about a rotational axis of the propeller, and the propeller converts its rotational movement into locomotion relative to the medium. The aspect ratio of at least one cross-section of the propeller is three or more. Also a helical or modifiedly helical propeller for converting rotational movement of the propeller into locomotion of the propeller relative to a medium at least partially surrounding the propeller, where the aspect ratio of at least one cross section of the propeller is three or more. And a method of producing a propeller, including the step of providing a plate extending along the helical axis, where the aspect ratio of at least one cross section of the plate is three or more.

A thrombectomy system is provided that, in various embodiments, a rotating impeller that may be translated within limits along a guidewire and within a catheter. The rotating impeller is, during operation, either located entirely inside or outside of the distal end of the catheter's lumen or at least partially outside of the distal end of the catheter's lumen. In some cases, the impeller may be prevented from rotating if at least partially inside the catheter's lumen. The rotating impeller may achieve a working diameter that is greater than its resting diameter.

A medical device for removing an intravascular thrombus includes: a rotatable tubular driving shaft in which a spiral-shaped carrier is provided on an inner surface thereof; a cutting part that is provided on a distal side of the driving shaft and cuts the thrombus; and an elongated resistive body that is disposed in a lumen of the driving shaft and can be rotated relative to the driving shaft.

Systems and methods can remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system for the treatment of pulmonary embolism (PE), deep vein thrombosis (DVT), cerebrovascular embolism, and other vascular occlusions.

Systems and methods are disclosed including apparatuses and methods for endoscopy such as an endoscope device operable to produce suction. An endoscope can include or use a cylinder for use at a distal end of an endoscope, and the cylinder can include a cylinder channel extending from a first end of the cylinder to a second end of the cylinder, and a rotor arranged within a working channel of the endoscope at the distal end of the endoscope. The rotor can be movable within the cylinder or the channel such as to help fragment or clear foreign bodies during a procedure.

A surgical apparatus for treating a blood clot in a vessel of a patient having an elongated member having an outer wall, a first hole at a distal portion and a second hole spaced proximally from the first hole positioned in a side wall. A first lumen is provided within the elongated member for blood flow through the second hole, through the lumen and exiting the first hole to maintain blood flow during treatment of the blood clot. An energy emitter emits energy to the blood clot or hardenings and a connector connects the energy emitter to an external energy source, wherein blood flows into the second hole positioned proximal of the blood clot and exits the first hole distal of the blood clot during activation of the energy emitter. In some instances when the apparatus is introduced from a retrograde ‘upstream” approach blood may flow through the device in the opposite direction.

A lateral disc cutter for morcellating and decorticating tissue of an intervertebral disc from between adjacent vertebrae. The device can be arranged in a retracted configuration for insertion via an access tube, and in an extended configuration for cutting of tissue in the target region. The blades may be extended to contact the concave endplate in an orientation that is substantially parallel to a mid-plane of the intervertebral disc. Blades of the device may be configured with a convex profile that substantially conforms to the concave shape of the endplate for enhanced contact length between the blade and the endplate. In some embodiments, the blades are configured for removal and replacement without need for tools, with the blades selectively determining a maximum displacement width of the morecellator assembly.

A surgical apparatus for treating a vessel blockage in a vessel of a patient having an elongated member having an outer wall, a first hole at a distal portion and a second hole spaced proximally from the first hole positioned in a side wall. A first lumen is provided within the elongated member for blood flow through the second hole, through the lumen and exiting the first hole to maintain blood flow during treatment of the vessel blockage. A motor driven impeller is rotatable during blood flow through the first lumen to enhance blood flow as blood flows into the second hole positioned proximal of the vessel blockage and exits the first hole distal of the vessel blockage during injection of fluid through one or more openings to treat the vessel blockage.
