Abstract

A transseptal insertion device suitable for facilitating precise and safe transseptal puncture of a cardiac interatrial septum (100) includes a sheath (12) that defines a lumen and has a distal end that is closest to the cardiac interatrial septum of a patient and a proximal end that is external to the patent, a balloon (14) that is connected to the distal end of the sheath (12) in which the balloon (14), when inflated, overhangs and extends past the distal end of the sheath, preventing accidental puncturing of the cardiac interatrial septum (100) and stabilizing the transseptal insertion device against fossa ovalis of the cardiac interatrial septum (100), and a dilator (16) that is positioned within the at least one lumen. The dilator (16) has a distal end and is designed to and is capable of precisely puncturing the cardiac interatrial septum without the use of a needle or other sharp instrument. The balloon (14) includes one or more ultrasound transceivers (26).

Description

[0001] related application [0002] This application claims U.S. Provisional Application No. US 62 / 538,552, filed July 28, 2017, entitled "Directional Balloon Transseptal Insertion Device for Medical Procedures," and filed November 29, 2017, entitled "U.S. Directional Balloon Transseptal Insertion Device for Medical Procedures," U.S. Provisional Application No. US 62 / 592,061, both of which are incorporated herein by reference in their entirety. technical field [0003] The present invention relates generally to cardiac catheters, and more particularly, to transseptal insertion devices adapted to facilitate rapid and safe transseptal puncture and insertion of catheters through the heart septum to provide The entrance to the left atrium. Background technique [0004] Cardiac catheterization is a medical procedure in which a long thin tube or catheter is inserted through an artery or vein into a specific area of ​​the heart for diagnostic or therapeutic purposes. More specifi...
