Balloon implant device

Abstract

A shoulder implant device includes one or more fixation features including an acromial intrusion element and an inflatable humeral balloon portion that receives a fluid through the acromial intrusion element. The intrusion element comprises a valve that can receive multiple needle sticks to add or remove fluid to or from the inflatable humeral balloon. The device is implanted in a subacromial space such that the one or more fixation features at least secure the device to the acromion and the inflatable balloon portion rests against the proximal end of the corresponding humerus. Fluid in the balloon portion maintains separation of the acromion and the humerus to reduce or prevent impingement.

Description

technical field [0001] The present invention relates generally to implant devices, and more particularly to a balloon implant device configured for placement in the shoulder region of a person. Background technique [0002] Physicians often see patients with diseases caused by displacement of soft or hard tissues relative to the surrounding body. A lot of effort was put into repositioning the organization and keeping it right. A common example is a broken bone, where doctors replace the bone and restrict its movement with a cast until the bone heals. [0003] Shoulder impingement syndrome is a clinical syndrome that occurs when the rotator cuff tendons become inflamed and infected as they pass through the passage between the acromion and humerus, also known as the subacromial space. Anything that narrows this space can lead to pain and decreased range of motion. [0004] Impingement can be caused by bony structures such as subacromial spurs (the bony protrusion of the acr...
