The purpose of the 'Dissolvable on-command Implant' is to act as a pressure equalizer tube in the eardrum, which has the unique characteristic that the tube can be dissolved with a specially formulated drop solution on-command. This tube can have various shapes and sizes, although the tube is usually a cylindrical tube with a hollow center, which maintains a ventilatory port for the middle ear space. With this design, the ear tube promotes drainage of middle ear fluid, lets air enter the middle ear, and allows for instillation of antibiotic drops.

A composition including PPF or a PPF copolymer that can be used to fabricate biodegradable structures. The composition can be used in 3-D patterning (e.g., 3-D printing and sterolighography) methods. For example, 3-D patternable compositions include PPF or a PPF copolymer, a photoinitiator or photoinitiators, and a resolution control inhibitor or inhibitors. The compositions can be used to make biodegradable structures (such as cardivascular scaffolds). The biodegradable structures can be surface functionalized. The biodegradable structures can be used in methods of blood delivery in an individual.
