AI Technical Summary

Benefits of technology

The present invention relates to an improved device for sealing a tissue opening, particularly a trocar tube opening in the heart after a valve replacement procedure. The device can seal the tissue opening and prevent secondary bleeding. It is flexible and filigree in design, allowing it to follow the movement of the heart without causing structural damage. It is made of a braiding that is soft and flexible and is adapted to the shape of the apex of the left ventricle. The braiding is made of Nitinol threads, which allows for self-deployment of the membrane-coated braiding. The device provides tight closure of the tissue opening and is safe for use in a beating heart.

Problems solved by technology

This type of valve surgery is highly invasive and exposes the patient to a number of potential risks associated with use of the heart-lung machine.
A problem in the transapical procedure is the haemostatic closure of the left ventricular apex.
Due to the high pressure created by the contraction of the heart severe problems may occur when the suture is not tight or disrupts.

Embodiment Construction

[0036]Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. FIG. 1 is a schematic illustration of the transapical valve insertion technique and shows the balloon catheter used to insert new artificial heart valves during Transapical Aortic Valve Implantation (TAAVI) according to the state of the art. Trocar tube 1 is inserted into the left ventricle 3 of the heart through the myocardium 2. A compressed valve prosthesis constructed from a stainless steel stent with an attached artificial valve 4 is placed on the balloon catheter 5, inserted into the apex of the left ventricle, and positioned directly inside the diseased aortic valve. Once in position, the balloon is inflated to secure the valve in place. The balloon is then deflated and removed leaving the new valve to function immediately.

[0037]FIG. 2 shows the sealing device sealing the opening in the myocardium. Trocar tube 1, via which...

Abstract

An implantable sealing device is disclosed herein and includes an elongated elastic member having distal and a proximal ends, at least one sealing element including braiding having outside and inside faces. The braiding can include of a plurality of fine threads of a memory metal alloy and wherein at least one face of the braiding is coated by a membrane. The braiding can also include a fixing member positioned at one of the distal and proximal ends of the elastic member and being positioned opposite to the braiding.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. §119(a) to European Patent Application No. EP12008240, filed with the European Patent Office on Dec. 10, 2012, the content of which is incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure relates to an implantable sealing device for sealing a tissue opening, more specifically a trocar tube opening in the left ventricle of the heart.[0004]2. Description of Related Art[0005]Deficient heart valves can be repaired or replaced using a variety of different types of heart valve surgeries. One general type of heart valve surgery involves an open-heart surgical procedure during which the heart is stopped and blood flow is controlled by a heart-lung bypass machine. This type of valve surgery is highly invasive and exposes the patient to a number of potential risks associated with use of the heart-lung machine.[0006]Due...
