Embrace HES

Embrace HESIt is a minimally invasive vascular embolization treatment method, which interventional radiologists can easily achieve immediate, complete, and permanent embolization.

Embrace HESIs a product that canEmbolic agents capable of embolizing ≤5 mm vessels, theirComposed of hydrogel and delivery system.

The hydrogel is mainly composed of PEG, initiator, and water, with the PEG solvent and initiator solvent stored in two syringes.
The delivery system consists of two coaxial microcatheters, with the outer catheter having an inner diameter ≥0.027 inches, and the inner catheter having an inner diameter of 1.2Fr and an outer diameter of 1.7Fr.

PEGSolventAndIntroductionHair DyeThe solvent is injected into two microcatheters simultaneously via syringes. When the two solutions reach the blood vessel through the microcatheters, the initiator will trigger PEG polymerization, forming a highly cross-linkedSoftHydrogel, thereby completely filling the pre-embolized blood vessel. According toInstyllaIntroductionEmbrace HESThe hydrogel can be degraded and absorbed by the human body within 6 months.The degradation products are excreted from the body through renal metabolism.

Due toEmbrace HESEmbolization with a liquid embolic agent, therefore, it has low requirements for vessel size and can tightly fill vessels ≤5mm.。

Embrace HESThe embolic effect in the patient persists without recanalization within 30 days.
