Resulting clot particles are captured by the mesh filter. Negative pressure may be applied along a proximal end portion of the sheath for aspirating remaining particles. Certain embodiments of the method are well-suited for treating deep vein thrombosis and do not require the use of thrombolytic drugs. | 2022-04-28 |
20220125452 | Treatment Of Ischaemia - An endovascular apparatus for crossing through an obstruction in a blood vessel comprises an elongate endovascular wire and a coupling. The coupling when in use transmits ultrasonic energy along the wire from an ultrasonic energy source to an active tip at a distal end of the wire. The coupling is arranged to couple the source to the wire at any of a plurality of discrete operational positions along the length of the wire for said transmission of ultrasonic energy to the active tip. | 2022-04-28 |
20220125453 | SYSTEM FOR TREATING THROMBUS IN BODY LUMENS - The present disclosure relates generally to thrombectomy devices. An exemplary catheter comprises: a central tube; an emitter assembly mounted over the central tube, wherein the emitter assembly comprises: a conductive sheath; a first insulated wire having a first curved distal portion; and a second insulated wire having a second curved distal portion, wherein the first curved distal portion and the second curved distal portion are positioned within the conductive sheath, and wherein the emitter assembly is configured to generate a plurality of cavitation bubbles or shockwaves when a pulsed voltage is applied to the emitter assembly; and an outer tube housing the emitter assembly, wherein the outer tube is configured to receive a conductive fluid, wherein the outer tube comprises a distal opening for releasing the plurality of cavitation bubbles or shockwaves and the conductive fluid in a forward direction to treat thrombus at a treatment site. | 2022-04-28 |
20220125454 | ACTUATED THROMBECTOMY DEVICE - A tip at the distal end of a catheter is designed to vibrates vigorously in order to break up a blood clot. Broken-up, the blood clot avoids “corking,” thus allowing it to be directly aspirated into the catheter. Unlike devices in minimally invasive surgery, where access to the organs to be removal are achieved through conveniently located small incisions, access to a location in the vascular space is achieved through a long flexible catheter, often 100 cm or more in length. An electroactive polymer (EAP) in at the tip of the distal end enables the vibration that breaks up the blood clot to be actuated from the proximal end of the catheter, without transferring mechanical action over substantially the entire length of the catheter. | 2022-04-28 |
20220125455 | ELECTRICALLY ENHANCED RETRIEVAL OF MATERIAL FROM VESSEL LUMENS - Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the removal device. The removal device can have a core assembly that includes a hypotube coupled to a first electrical terminal and a pushwire coupled to a second electrical terminal, the pushwire extending through the hypotube lumen. An insulating layer separates the hypotube and the pushwire, and an interventional element is coupled to a distal end of the pushwire. The interventional element can be disposed adjacent to a thrombus. An electrical signal is delivered to the interventional element to promote adhesion of the thrombus to the interventional element. The electrical signal can optionally be a periodic waveform, and the total energy delivered can be between 0.75-24,000 mJ and the peak current delivered via the electrical signal can be between 0.5-5 mA. | 2022-04-28 |
