Benefits of technology

[0010]Those of ordinary skill in the art having the benefit of the present disclosure will appreciate that accelerated patch attachment using an adhesive or immediate patch release using temporary support of a bio-absorbable thread c...

Problems solved by technology

Compromised health may be caused by cardiovascular structures that adversely affect the proper flow of blood.
Such structures may be abnormalities that affect a relatively small subset of the population, and others may be common and not normally pathogenic, yet become so due to extrinsic causes.
Congenital heart defects can cause an abnormal distribution of cardiovascular pressures and the di...

Embodiment Construction

[0022]In the disclosure that follows, in the interest of clarity, not all features of actual implementations are described. It will of course be appreciated that in the development of any such actual implementation, as in any such project, numerous engineering and technical decisions must be made to achieve the developers' specific goals and subgoals (e.g., compliance with system and technical constraints), which will vary from one implementation to another. Moreover, attention will necessarily be paid to proper medical and engineering practices for the environment in question. It will be appreciated that such development efforts might be complex and time-consuming, outside the knowledge base of typical laymen, but would nevertheless be a routine undertaking for those of ordinary skill in the relevant fields.

[0023]The present invention encompasses methods for accelerated attachment and / or release of an occlusive device placed at the site of a physiological opening, especially but no...

Abstract

A method and apparatus for suture-less placement of an occluding patch in which release of the device can be accelerated. In one embodiment, an inactive form of an adhesive is applied on the area of the patch that will come into contact with cardiac tissue; this allows for the introduction and necessary manipulation of the catheter system until activation of the adhesive occurs. In accordance with one aspect of the invention, the adhesive properties of certain polymeric materials are relied upon rather than their ability to cure or harden into a specific shape. In another embodiment, the patch is immediately released utilizing a detaching mechanism on the balloon or the balloon catheter which supports the patch; the patch along with the inflated balloon remain on the cardiac structure occluding the opening.

Description

RELATED APPLICATION DATA[0001]This application claims the priority of prior provisional U.S. patent application Ser. No. 61 / 270,455 filed on Jul. 9, 2009, which application is hereby incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]This invention relates generally to cardiovascular devices, intended to occlude circulatory communications that may be or may become detrimental to patient health. More specifically, this invention encompasses accelerated release methods for an occlusion methodology involving sutureless delivery of an occlusion patch to a physiological opening.BACKGROUND OF THE INVENTION[0003]Compromised health may be caused by cardiovascular structures that adversely affect the proper flow of blood. Such structures may be abnormalities that affect a relatively small subset of the population, and others may be common and not normally pathogenic, yet become so due to extrinsic causes. Examples of the former are congenital heart defects including...
