A control apparatus of an insertion apparatus in which a state specifying unit specifies a state of an insertion member to carry out vibration control depending on the state, thereby removing getting-stuck of a tip of the insertion member with a vibration having such a proper magnitude as not to cause an overload in a case where the tip of the insertion member is gotten stuck.

An implanted device, such as an inferior vena cava filter, that is partially embedded in soft tissue is retrieved by coupling a vibration device to the implanted device. The implanted device is disembedded from the soft tissue at least in part by generating a vibration with a vibration generator, transmitting the vibration along the vibration transmission apparatus to the implanted device, and vibrating the implanted device. The implanted device is then moved away from the embedding site. A medical device assembly includes the vibration generator, the implantable device and the vibration transmission apparatus.

An elongate endovascular element for crossing through an obstruction in a blood vessel comprises: a proximal section; a distal tip section of smaller diameter than the proximal section; and a distally-tapering intermediate section extending between the proximal and distal tip sections; wherein the tapered intermediate section has a length that is substantially λ/2 or a multiple of λ/2 , where λ is a wavelength of a driving frequency that will produce longitudinal resonance in the element.

A generator, ultrasonic device, and method for controlling a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency. The control circuit controls the temperature of the ultrasonic blade based on the inferred temperature

An intracorporeal pressure shock wave includes an expandable pressure shock wave reflector at the distal end of an intracorporeal catheter to direct shock waves from a shock wave generator within a human or animal blood vessel or body lumen.

A system for aspirating thrombus and delivering an agent includes an aspiration catheter having a supply lumen having a proximal end, a distal end, and a wall, and an aspiration lumen having a proximal end, an open distal end, and an interior wall surface adjacent the open distal end, and at least one orifice at or adjacent the distal end of the supply lumen, in fluid communication with the aspiration lumen and located proximally of the open distal end of the aspiration lumen, wherein the at least one orifice is configured to create a spray pattern that is caused to impinge on the interior wall surface of the aspiration lumen such that the spray pattern upon impinging on the interior wall surface is caused to transform into at least a substantially distally-oriented flow capable of exiting the open distal end of the aspiration lumen.

A device for acoustic calculi fracture can include an acoustically-transmissive elongated probe body extending between a distal portion and a proximal portion and an acoustically-transmissive probe tip that can be selectively user-interchangeable with the probe body. The probe body can have a lumen longitudinally therethrough. A method of fracturing calculi can include interchanging a probe tip with a probe body by a user without requiring an additional tool and transmitting acoustic energy via the probe body and the probe tip to a calculus to at least partially fracture the calculus.

The present disclosure includes a calculi fracture device having an acoustic transducer for transferring acoustic energy via a primary fragmentation probe to fracture a calculi mass into calculi fragments, an evacuation tube connecting the probe to a pressure source, and a secondary fragmentation device located in an evacuation pathway extending along the fragmentation probe and the evacuation tube to further break up the calculi fragments to inhibit clogging at a more proximal location in the evacuation pathway. A method of inhibiting clogging of a calculi fracture device can include receiving, from a primary fragmentation device, fragments of a calculi mass along a passage of a evacuation pathway of the calculi fracture device and further breaking up the calculi fragments along the passage of the evacuation pathway at a location that is more proximal to a primary fragmentation location.

A lithotripsy device can comprise a handpiece, a lithotripsy probe extending from the handpiece, an energization source configured to deliver an energy to a distal end of the lithotripsy probe, a suction passage extending from the distal end of the probe and through the handpiece, and a capture device comprising a container comprising a storage space, an entry port configured to couple to the handpiece at the suction passage, and an exit port, and a capture element connected to the container and configured to facilitate capture of stone fragments within the storage space. A method can comprise fragmenting stones with a lithotripsy device, drawing a vacuum through the lithotripsy device to pull stone fragments and waste fluid therethrough, pulling the vacuum through a stone capture device connected to the lithotripsy device, depositing stone fragments within the stone capture device using a capture element, and drawing the vacuum through the device.

An apparatus includes a transmission member having a proximal end portion and a distal end portion. The transmission member is configured to be inserted into a bodily lumen, and is configured to transfer ultrasonic energy from the proximal end portion to the distal end portion. The transmission member defines a lumen along a longitudinal center line of the transmission member. The distal end portion of the transmission member includes a concave engagement surface and a distal end surface. The distal end surface defines a plane that intersects the longitudinal center line of the transmission member at an angle of between about 75 degrees and about 105 degrees. The engagement surface is configured to engage a target tissue within the bodily lumen to limit movement of the target tissue along the longitudinal center line. The engagement surface defines an opening in fluid communication with the lumen.
