Securement Structure for Joining Medical Device Parts

Abstract

A securement structure is positioned inside a channel of a first medical device to facilitate securement of the first medical device to a second medical device. The first medical device may be a ligation banding cap, and the second medical device may be an endoscope. The securement structure is adapted to be compressed between the second medical device and the first medical device to secure them together. This allows parts of different sizes to fit together.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to U.S. provisional application Ser. No. 61 / 624,696 filed Apr. 16, 2012, the disclosure of which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The invention relates to structures and methods for joining parts together. In some embodiments, the invention relates to a securement structure for joining a ligation banding cap to an endoscope or the like.BACKGROUND OF THE INVENTION[0003]Various medical procedures involve the use of medical devices that are joined together. For example, certain medical procedures involve the attachment of devices to the end of an endoscope or the like.[0004]One example of a medical procedure that can involve the use of an endoscope is a ligation procedure. Ligation is a medical procedure whereby a physician ties off or mechanically constricts a piece of body tissue with a ligature such as a suture, clip or band. In certain procedures, the purpose ...

AI Technical Summary

Benefits of technology

The present disclosure describes a securement structure that is used to secure two medical devices together. The securement structure is placed inside a channel of one medical device and compressed between the two medical devices when the second medical device is placed inside the first medical device. This helps to securely attach the two medical devices together. The securement structure may be made of resilient securement projections that compress between the two medical devices to provide a secure and tight connection. This securement structure can be used with a cap assembly that is designed to be attached to the end of an elongated medical device, such as an endoscope. The use of the securement structure simplifies the attachment process and improves the stability and reliability of the connection.

Problems solved by technology

For example, a physician can remove target tissue by ligating it to obstruct circulation through the target tissue, thereby causing the tissue to die and slough off.

Generally, however, such prior ligation banding cap assemblies were not suitable for fitting on a wide range of endoscope sizes.

In some instances, prior means for joining medical devices together has had the potential to lead to problems such as misalignment, instability, jarring, inadequate sealing, poor suction, poor visualization, separation of parts and / or other issues arising from a poor connection.

The potential for these problems is exacerbated when parts of different sizes are joined together.
