Patent number: 11540861Abstract: Apparatus for puncturing a fossa ovalis includes a catheter, which has a distal portion that is shaped so as to define a catheter distal end opening at a distal end of the catheter, and first and second lateral openings. The catheter is shaped so as to define a central catheter lumen open through the catheter distal end opening. A flexible longitudinal member passes from a proximal portion of the catheter to the distal portion of the catheter, out of the first lateral opening, and into the second lateral opening, so as to form a loop outside the catheter. A puncturing element is slidably disposed within the central catheter lumen, and is configured to puncture a hole through the fossa ovalis by being advanced out of the catheter distal end opening and through the fossa ovalis. Other embodiments are also described.Type: GrantFiled: March 5, 2020Date of Patent: January 3, 2023Assignee: TRANSSEPTAL SOLUTIONS LTD.Inventor: Elad Sapir

Publication number: 20220265316Abstract: Apparatus for puncturing a fossa ovalis includes a catheter shaped so as to define a central catheter lumen open through a catheter distal end opening. An angle between (i) a first line running between first and second lateral openings defined by the catheter and (ii) a second line that is parallel to a central longitudinal axis of the catheter when the catheter is straight, is between 30 and 150 degrees. A flexible longitudinal member passes (a) from a proximal portion of the catheter to a distal portion of the catheter, (b) out of the first lateral opening, and (c) into the second lateral opening, so as to form a loop outside the catheter. The flexible longitudinal member is configured to assume a deployment configuration in which a distal-most portion of the loop is curved and is distal to the catheter distal end opening. Other embodiments are also described.Type: ApplicationFiled: May 2, 2022Publication date: August 25, 2022Applicant: TRANSSEPTAL SOLUTIONS LTD.Inventors: Elad SAPIR, Francesco MAISANO, Eyal TEICHMAN

Publication number: 20220241010Abstract: A method is provided including inserting a catheter into a right atrium and advancing a distal portion of the catheter toward a roof of the right atrium. A flexible longitudinal member is deployed from the catheter, such that a deployed portion of the flexible longitudinal member is loop-shaped. The deployed portion of the flexible longitudinal member is brought into contact with a single stabilization site located on the roof of the right atrium, between the roof and an interatrial septum, or on the interatrial septum superior to a fossa ovalis. A needle is deployed from the catheter and brought in contact with a hole site on a surface of the interatrial septum outside the fossa ovalis. A hole is formed through the interatrial septum at the hole site with the needle. The deployed portion of the flexible longitudinal member is withdrawn toward the catheter. Other embodiments are also described.Type: ApplicationFiled: April 13, 2022Publication date: August 4, 2022Applicant: TRANSSEPTAL SOLUTIONS LTD.Inventor: Elad SAPIR

Patent number: 9788858Abstract: Apparatus and methods are described, including apparatus for puncturing a fossa ovalis of a heart. The apparatus includes a catheter shaped to define a catheter lumen. A puncturing element is slidably disposed within the catheter lumen, and is deployed from a distal portion of the catheter and to puncture the fossa ovalis. A probing element is deployed from the distal portion of the catheter. Upon being deployed, the probing element probes tissue near the fossa ovalis, the probing element having a first configuration thereof upon probing the tissue near the fossa ovalis. Upon probing tissue of the fossa ovalis, the probing element facilitates positioning of the puncturing element, by automatically adopting a second configuration thereof that is different from the first configuration.
