  • Patent number: 11998236
    Abstract: Intravascular delivery system is designed for a safe and efficient access to secondary and tertiary vascular structures, such as the branches of the coronary sinus, to enhance the delivery and deployment of various catheters, such as, for example, pacemaker electrical leads. The over-the-wire system features a straight, or alternatively shaped, micro-catheter distal tip of an inner catheter that seamlessly cooperates with a peel-away reinforced outer catheter. The inner catheter and the peel-away reinforced outer catheter are advanced in their engaged mode of operation towards (or beyond) the target site. Subsequently, the inner and outer catheters are disengaged, and the inner catheter is removed from the outer catheter. A pacemaker lead may be advanced over the wire inside the outer catheter to the target site for deployment. Subsequently, the outer catheter is easily split and may be rapidly removed from the blood vessel.

  • Patent number: 11964091
    Abstract: A method and system for performing transseptal extracorporeal membrane oxygenation is disclosed. The method may include puncturing a septum between the right atrium and the left atrium and advancing a catheter system through the puncture and into the aorta. A first portion of the catheter system can remove blood from the patient, in some examples near the inferior vena cava. A second portion can return oxygenated blood to the patient, through the transseptal puncture and into the aorta.

  • Publication number: 20240033479
    Abstract: A catheter-based/intravascular ablation (denervation) system includes a multiplicity of needles which expand open around a central axis to engage the wall of a blood vessel, or the wall of the left atrium, allowing the injection of a cytotoxic or/or neurotoxic solution for ablating conducting tissue, or nerve fibers around the ostium of the pulmonary vein, or circumferentially in or just beyond the outer layer of the renal artery. The expandable needle delivery system is formed with self-expanding materials and include structures, near the end portion of the needles, or using separate guide tubes. The system also includes means to limit and/or adjust the depth of penetration of the ablative fluid into the tissue of the wall of the targeted blood vessel. The preferred embodiment of the catheter delivered through the vascular system of a patient includes a multiplicity of expandable guide tubes that engage the wall of a blood vessel.

  • Publication number: 20230404457
    Abstract: An intravascular catheter for peri-vascular nerve activity sensing or measurement includes multiple needles advanced through supported guide tubes (needle guiding elements) which expand with open ends around a central axis to contact the interior surface of the wall of the renal artery or other vessel of a human body allowing the needles to be advanced though the vessel wall into the perivascular space. The system also may include means to limit and/or adjust the depth of penetration of the needles. The catheter also includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened needles are advanced to penetrate into the vessel wall.

  • Publication number: 20230404660
    Abstract: At the present time, physicians often treat patients with atrial fibrillation (AF) using radiofrequency (RF) catheter systems to ablate conducting tissue in the wall of the Left Atrium of the heart around the ostium of the pulmonary veins. These systems are expensive and take time consuming to use. The present invention circular ablation system CAS includes a multiplicity of expandable needles that can be expanded around a central axis and positioned to inject a fluid like ethanol to ablate conductive tissue in a ring around the ostium of a pulmonary vein quickly and without the need for expensive capital equipment. The expansion of the needles is accomplished by self-expanding or balloon expandable structures. The invention includes centering means so that the needles will be situated in a pattern surrounding the outside of the ostium of a vein. Also included are members that limit the distance of penetration of the needles into the wall of the left atrium.

  • Patent number: 11779362
    Abstract: A catheter for facilitating re-entry of a re-entry wire into a true lumen or into any desired region of a blood vessel may have an elongate shaft with a first lumen. A distal port and a first proximal port are fluidly coupled with the first lumen. A wire re-entry port is adjacent the distal end of the elongate shaft. The wire re-entry port has a re-entry axis. An ultrasound transducer on the catheter is configured to produce an image the blood vessel, and has a central axis that allows visualization of the re-entry wire as it exits the re-entry port and re-enters the true lumen. This allows the operator to ensure that the re-entry wire re-enters the true lumen in a desired location and does not damage the vessel.

The outer delivery sheath and the inner member are modified for different engagement/disengagement mechanisms operation. The delivery micro-catheter provides for an improved crossability for the balloon member to the treatment site in an atraumatic, expedited and convenient fashion. During the cardiac procedure, a guidewire and a guide catheter are advanced to the vicinity of the treatment site within a blood vessel.

  • Patent number: 11759315
    Abstract: Methods, apparatuses, and systems for performing a valve replacement or repair. Apparatuses may include systems and may include an outer catheter, one or more interchangeable inner catheters and a guidewire. The inner catheter(s) may be detachably coupled to the outer catheter. The inner catheter and outer catheter may surround the guidewire such that the inner and outer catheters may be advanced in a monorail fashion within the patient. Example methods may include percutaneously inserting the outer and inner catheter(s) into an artery and advancing toward the right atrium, through a transseptal atrial puncture, and advanced to the left atrium and left ventricle to access the aortic valve.
