Latest Patents

Ren's latest patents include a method of making injectable cements and a method of making water-soluble injectable calcium polyphosphate gels. The first patent describes a groundbreaking process for converting amorphous calcium polyphosphate (ACPP) and other polyphosphate salts with various types of calcium phosphate into a new calcium phosphate product, specifically dicalcium phosphate dihydrate (DCPD). This innovative injectable paste serves as an alternative to conventional calcium phosphate cement (CPC) bone cement, offering excellent properties in osteoconductivity and osseointegration, making it suitable for bone void repair. Additionally, it can function as a drug delivery device in tissue engineering due to its strong bonding capabilities with drug molecules.

The second patent outlines an injectable calcium polyphosphate (CPP) gel characterized by a dense structure, which can be utilized as a bone void filler in medical fields such as orthopedics and dentistry. The amorphous CPP powder, with a fine particle size, can be completely dissolved in water, resulting in a homogeneous gel that exhibits viscoelasticity and superior adhesion to natural bone and implant surfaces. This biomimetic and biodegradable gel demonstrates strong osteoconductivity and osteoinductivity, with controllable mechanical strength through various modifications.
