The present teachings provide systems, devices, and methods for reshaping the heart and reducing valve regurgitation. A device can be positioned proximate the heart and have a delivery profile and an inflated profile. The device can have a primary cavity and a secondary cavity, and an adhesive inside the secondary cavity. An injectable medium can be injected to the primary cavity of the device. As the primary cavity is filled, the adhesive is forced out of the secondary cavity to adhere the device. The inflated device can exert pressure on the heart, change the shape of a valve annulus, and allow a better coaptation of the valve leaflets. 1. A system comprising:an access sheath, configured to be introduced to a treatment location outside a heart of a subject;a delivery catheter; a tissue-binding adhesive;', 'a flexible outer layer encasing a primary cavity and a secondary cavity outside of the primary cavity, a portion of the flexible outer layer outside of the secondary cavity having a plurality of pores between the secondary cavity and the outside of the flexible outer layer;', 'a barrier separating the primary and secondary cavities, inhibiting moisture from crossing the barrier; and, 'a device configured to be positioned at the treatment location, against the right side of the heart, the device comprisingwherein the device has a collapsed delivery profile and an inflated deployment profile, and in the collapsed delivery profile, the device is dimensioned to be advanced, within the access sheath, to the treatment location, while the secondary cavity contains the tissue-binding adhesive;wherein the device is inflatable to the inflated deployment profile by introducing an injection medium into the primary cavity, andwherein introducing the injection medium into the primary cavity forces at least some of the tissue-binding adhesive out of the secondary cavity via the pores.2. The system according to claim 1 , wherein the barrier separating the primary and secondary ...
