The inventive device is a mechanical wave inducing device being connectable to a needle. The device has a displacement source and a driving signal connection part in order to connect the displacement source to a signal source. The device has also two connections parts, which are connected to the displacement source, and which each wing part has a connection point to be attached with the needle. The wing parts are converters in order to convert longitudinal mechanical wave movement created by the displacement source into transversal mechanical wave movement for the needle, and at least one connection point is designed to match the transversal mechanical waves to the needle.

A method for operating an ultrasonic reentry device, includes: providing an ultrasound transmission member having a proximal end and a distal end; providing a catheter body having a lumen surrounding the ultrasound transmission member; providing a dilator slidably disposed within the lumen of the catheter body, the dilator surrounding the ultrasound transmission member; and exposing the distal end of the ultrasound transmission member from a distal end of the dilator.

A surgical handpiece nosecone having an end overmold portion and/or an internal overmold portion. The end overmold portion is located at an end of the nosecone and compressed between the surgical handpiece housing and nosecone. The internal overmold portion is positioned radially about the nosecone on the inner surface to provide a fluid tight seal that prevents ingress of irrigation fluid into the housing.

Systems and methods for treatment using acoustic shock waves within an enclosed negative pressure chamber to fragment or otherwise to modify plaque in a patient's penile shaft.

Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device, such as a glue gun, that is operably connected to a delivery catheter that can be advanced across a treatment zone in the vein. The delivery catheter can be used to deliver one, two, or more boluses of media (e.g., cyanoacrylate) to occlude the vein along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein by a compression element, such as a hand or multifunctional ultrasound transducer, to occlude portions of the vein along the treatment zone prior to or during the introduction of the boluses of media.

The present invention provides methods and devices for treating endovascular disease. Vibrational energy is delivered to change compliance and increase permeability at the treatment area. To improve clinical outcomes, one or more therapeutic drugs may be delivered to the treatment area.

A device for the fragmentation of a calculus includes a probe, and a drive unit for deflecting the probe along the longitudinal extension thereof. The drive unit includes a first drive element for periodically deflecting the probe and a second drive element for the pulsed deflection of the probe. The drive unit is configured such that periodic deflection and pulsed deflection can be superimposed.

A catheter assembly including, in some embodiments, a sonic connector at a proximal end of a core wire, a damping mechanism around a proximal end portion of the core wire, and a heat sink connected to the damping mechanism. The sonic connector is configured to couple to an ultrasound-producing mechanism and transmit vibrational energy to the proximal end of the core wire, which core wire includes a distal end portion configured to modify intravascular lesions. The damping mechanism includes a gasket system around the proximal end portion of the core wire in a damping-mechanism bore of the catheter assembly. The damping mechanism is configured to damp the vibrational energy. A system including, in some embodiments, the catheter assembly and the ultrasound-producing mechanism is also disclosed.

A lithotripter is provided that includes a lithotripsy apparatus for treatment of a urinary tract stone by fragmentation. The lithotripsy apparatus includes a lithotripsy wave guide shaft configured to transmit an energy form to at least one urinary tract stone. The lithotripter includes a sensing device configured to provide signal data for determining optimal application of energy during treatment with the lithotripsy apparatus. The lithotripter includes a processor configured to collect the signal data and provide feedback to a user. The processor has a control logic configured to determine at least one of: a) if the lithotripsy wave guide shaft is in contact with a tissue; b) if the lithotripsy wave guide shaft is in contact with a stone; c) type of stone; d) if a user is applying force in excess of a predetermined threshold; and e) physical characteristics of a stone. A method is also provided.

A catheter including a core wire, a sonic connector at a proximal terminus of the core wire, and a tip member at a distal terminus of the core wire. The core wire can be at least partially disposed within a lumen of an elongate body. The sonic connector can be configured to couple to an ultrasound-producing mechanism. The tip member can be welded to the core wire at one or more weld locations between the tip member and the core wire, and the tip member can flare from the core wire at one or more weld-free locations between the tip member and the core wire. The manner in which the tip member can flare from the core wire at the one or more weld-free locations is characteristic of ultrasonic activation of the tip member.
