Devices, systems, and methods for engaging a tissue

Abstract

Devices, systems and methods are disclosed for providing chronic or temporary tissue support and / or restoration that does not require that the targeted tissue be severed and / or punctured. A device having two components and at least one connector for maintaining a prescribed distance between the two components is described. Such devices, systems and methods may be used on any tissue of a body and may be delivered through laparoscopic and / or endoscopic procedures.

Description

PRIORITY[0001]The present application is related to, claims the priority benefit of, and is a U.S. continuation patent application of, U.S. patent application Ser. No. 12 / 546,139, filed Aug. 24, 2009 and issued as U.S. Pat. No. 9,402,757 on Aug. 2, 2016. The contents of the foregoing patent application and patent are hereby incorporated by reference in their entirety into the present disclosure.BACKGROUND[0002]Organ and tissue surgical restoration are clinical techniques that may be applied to numerous different body tissues, ranging from blood vessels to whole organs. Conventionally, such surgical techniques require the use of incisions, pins, staples and / or significant sutures in order to alter the tissue's anatomy. For example, surgical gastric restoration often employed to treat obesity and typically involves the reorganization of the digestive tract. Conventional examples of such procedures involve attempts to either 1) restrict food intake into the body via a restrictive baria...

AI Technical Summary

Benefits of technology

The present patent describes an implantable restraining device for reducing tissue distension or remodeling in a body cavity. The device comprises a first engaging component, a second engaging component, and at least one connector for joining the components together. The first and second engaging components can be straight, curved, or circular in configuration. The device also includes a mesh curtain to limit organ distension or remodeling when the device is positioned about an organ. The at least one connector can be made of materials such as polyurethane, polyethylene, polytetrafluoroethylene, nitinol, silastic, titanium, or stainless steel. The device can be used in a method to restore a targeted tissue by inserting it into a body cavity and positioning the engaging components over the targeted tissue. The invention provides an improved implantable restraining device that can be used to treat various medical conditions such as gastrointestinal motility disorder.

Problems solved by technology

As the digestive tract contains numerous enzymes, strong acids and multiple species of bacteria that assist with digestion, the perforation of an organ and / or tissue thereof is particularly problematic due to the likelihood of leakage therefrom and / or increased risk of serious infection.

As such, conventional gastric surgical restoration procedures have high rates of post-operative complications that may require prolonged hospitalization and even additional operations, and are often irreversible and / or permanently affect the restored tissue and / or organ.
