Problems solved by technology

Transseptal puncture must be performed with great precision as accidental puncture of surrounding tissue can cause very serious damage to the heart
In addition, transseptal puncture may require complex instruments that do not contribute to the accuracy of the puncture
[0007] The use of devices available today presents many challenges to physicians attempting to puncture the interatrial septum and perform cardiac catheterization

Abstract

A transseptal insertion device includes a sheath that defines a lumen and has a distal end that is closest to the cardiac interatrial septum of a patient, at least one balloon connected to the distal end of the sheath, in which the at least one balloon, when inflated, overhangs and extends past the distal end of the sheath, preventing accidental puncturing of the cardiac interatrial septum and stabilizing the transseptal insertion device against fossa ovalis of the cardiac interatrial septum, and a dilator positioned within the lumen. The dilator has a distal end and is capable of precisely puncturing the cardiac interatrial septum without the use of a needle or other sharp instrument. The at least one balloon is connected to at least one hypotube through which the at least one balloon is inflated or deflated by gas or fluid flowing through the at least one hypotube.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application Serial No. US 62 / 821,062, filed March 20, 2019, the entire contents of which are incorporated herein by reference. 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 cardiac septum to provide access to the left atrium when performing left atrial interventions. path. 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 diagnosis or treatment. More specifically, catheters can be inserted into heart chambers, blood vessels, and valves. [0005] Cardiac catheterization is used in procedures such as coronary angiography and left ventri...
