A device for occluding an opening in a body and associated methods

Abstract

The disclosure relates to a device for occluding an opening in a body and associated methods. The device of this disclosure has the advantage that a second element of the device can be made more flexible than a first element and thereby the device is less prone to increase the rupture size of an opening. In one example, a device (1) for occluding an opening in a body is disclosed, which comprises a first element (2), comprising at least one thread or wire (3), and a second element (6), such as a shaft section, said second element (6) being at least in a longitudinal section tubular or oval and comprising a braided material, said braided material comprising at least one thread or wire (9), and wherein a diameter of said second element (6) is of substantially the same size or smaller than said opening for all longitudinal sections, when said device (1) is in a preset, expanded configuration.

Description

technical field [0001] The present invention generally relates to the field of medical implants or prostheses. More specifically, the present invention relates to devices and related methods for closing openings in the human body. Background technique [0002] The present invention relates to the sealing of openings in the walls of human vessels or cardiac cavities, such as blood vessels or the human heart, and more precisely to devices for closing openings in the human body, and methods for manufacturing such devices . [0003] There are holes and openings that are not created by interventional therapeutic activities, they are acquired by disease or congenitally. Some products used to close acquired or birth defects are devices with an umbrella-shaped disc with spikes and a drape. One disc is placed on one side of the opening to be closed and the other disc is placed on the other side of the opening to be closed. Thereafter, the discs are pressed against each other an...

AI Technical Summary

Problems solved by technology

[0006] When using prior art closures to close a channel of such a complex defect, it may be difficult to completely seal such a gap of opening, so prior art devices do not always work well with such ruptures, as they sometimes tear further apart the tissue that has already been torn, and thus increase the size of the rupture

[0007] Again, when it comes to breakouts, prior art devices may not always cover all shunts or channels

[0008] Further, for some defects such as ruptures, prior art devices may cover an unnecessarily large portion of healthy tissue
