Abstract
Hydrogel fracturing devices are described herein that include a chamber with an inlet, outlet, and at least one fracturing structure which extends across the entire internal diameter of the chamber. The fracturing structure includes one or more apertures or screens. The fracturing device may be connected to a syringe and/or ampoule containing a hydrogel formulation. The hydrogel formulation may then be fractured by forcing the formulation through the fracturing device.
Claims14
A hydrogel fracturing device comprising:
- an outer wall defining a chamber therein;
- an inlet in fluid connection with the chamber;
- an outlet in fluid connection with the chamber;
- and
- at least one fracturing structure extending across an internal diameter of the chamber;
- wherein the inlet of the fracturing device is attached to a syringe containing a hydrogel formulation, the outlet of the fracturing device is coupled to a needle, and the hydrogel comprises at least 1% agarose by weight.
