Example lithotripsy probe assemblies, lithotripsy systems, and methods of using a lithotripsy system are described. An example lithotripsy probe assembly has a probe coupling, a probe, and a plurality of sealing members disposed on the probe coupling. The probe coupling has a probe coupling proximal end, a probe coupling distal end, a probe coupling length, and a probe coupling main body that defines a plurality of projections, a probe coupling first passageway, and a probe coupling second passageway. The probe coupling length extends from the probe coupling proximal end to the probe coupling distal end. The probe is attached to the probe coupling and is partially disposed within the probe coupling first passageway. The probe has a probe proximal end, a probe distal end, and a probe length that extends from the probe proximal end to the probe distal end and is greater than the probe coupling length.

A method for performing an endovascular procedure using ultrasonic energy includes providing a first sheath having a proximal end portion and a distal end portion, and having a first window in the distal end portion; positioning a wave guide in the first sheath for delivering the ultrasonic energy through the first window for performing the endovascular procedure; and selectively covering the first window with a cover.

A wire connector assembly for an ultrasonic therapy catheter system including an ultrasound generator is presented. The wire connector assembly includes a sonic connector that is configured to couple to the ultrasound generator and receive ultrasonic energy therefrom. The sonic connector includes a body having a passageway that extends therethrough, and the passageway includes a tapered surface. The wire connector assembly further includes a wire that engages the tapered surface and extends outwardly from the passageway. The wire is configured to receive ultrasonic energy from the sonic connector.

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.

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.

An example aspiration system includes an inner member configured to be received within an aspiration catheter lumen and disrupt a thrombus positioned within vasculature of a patient. The inner member includes a distal member at a distal portion of an elongated support member, where the distal member is configured to fit within the aspiration catheter lumen. The distal member defines a larger cross-sectional dimension than the elongated support member, the cross-section being taken in a direction orthogonal to a longitudinal axis of the support member, and is configured to be deployed distally outward from a distal opening of the aspiration catheter lumen to contact and disrupt a thrombus to facilitate the efficiency of a medical aspiration procedure. The distal member may include one or more tapered portions and a surface disruption configured to aid with the thrombus disruption.

An ultrasonic device may include an electromechanical ultrasonic system that includes an ultrasonic transducer coupled to an ultrasonic blade. A method of delivering energy to the ultrasonic device may include sensing a vessel type in contact with the blade, determining that the vessel type is either a vein or an artery, and delivering power to the transducer based on the vessel type. Power may be applied to the transducer at a power level P that differs from a nominal power level Pn for a period T that differs from a nominal period Tn based on the vessel. The power level P may be lower than Pn for a period T that is longer than Tn when the vessel is a vein. Alternatively, the power level P my be greater than Pn for a period T that is shorter than Tn when the vessel is an artery.

A stone or tissue capture device comprises a shaft with a deployable sweeping/containment structure at its distal end. The shaft is adapted to be removably placed over and connected to a conventional endoscope. The combination of the capture device and endoscope can be introduced into the various body lumens to capture, fragment/excise, and remove stones or tissue from the bladder and kidney, stomach, peritoneum, and from lumens such as the ureter, colon, hepatic ducts, airways, or blood vessels.

A surgical method treats infections on a lead positioned at least partially within a patient's body. The surgical method includes uncoupling the lead from a pulse generator. The lead is then coupled to an ultrasound wave generator. Ultrasound waves are propagated from the ultrasound wave generator through the lead. Systems are disclosed.

Provided herein are dual-lumen catheters, systems, and methods thereof. In some embodiments, for example, a catheter assembly configured for modifying intravascular lesions is provided including a core wire, a dual-lumen extrusion including the core wire, and a manifold disposed around a portion of the dual-lumen extrusion. The core wire includes a proximal end configured to vibrationally couple to an ultrasound transducer. The dual-lumen extrusion includes a first lumen and a second lumen. The core wire is disposed within the first lumen, and the second lumen is configured to accommodate a guidewire. The manifold is disposed around at least a skived proximal-end portion of the dual-lumen extrusion, wherein the skived portion includes the second lumen without the first lumen. In some embodiments, the catheter assembly further includes the ultrasound transducer. In some embodiments, a system console includes the ultrasound transducer.
