Titanium Nitride coating technology

Prevent Nickel leaching.

Accelerate endothelialization and close defect rapidly. 

Soften Nitinol material and provide a more compliant and flexible implant.

Excellent braided structure

Offer potential benefits to decrease the chance of clot formation on the left atrial disc with braided technology instead of distal clamp.

Offer better adaptation in the interatrial septum with flexible disc.

Strategic Membrane Selection 

PTFE membrane was sewn into PDA devices to decrease residual shunt.

PET membrane was sewn into the ASD/PFO devices to get lower profile sheath.

-         Static magnetic field of 3.0 Tesla or less

-         Spatial gradient filed of 680Gauss/cm

-         Maximum whole-body-averaged specific absorption rate (SAR) of 2W/kg for 15 minutes of scanning


Expected Lifetime of ASD Occluder Device

The ASD Occluder is a permanently implanted device. Under normal circumstances, it will stay in the patient's body for life, unless it is required to be removed by the physician’s professional judgment.

Material/Substances in Contact with Patient

The Occluder implants are composed of

-         NiTi (80%-95%), stainless (2%-20%), PA (0.1%-0.8%), PET (1.2%-8.9%) in HeartR ASD occluder;

-         NiTi (80%-95%), TiN (~0%), stainless (2%-20%), PA (0.1%-0.8%) and PET (1.2%-8.9%) in Cera ASD occluder;

-         NiTi (85%-98%), TiN (~0%), PA (0.2%-1%), PET (2%-15%) in Ceraflex ASD occluder.

During the intended use, heart (atrium), left superior pulmonary vein, femoral vein as well blood will come in contact with the device.

Note: If you have a history of metal allergies, you should ask your doctor. Your doctor will help you decide whether it is appropriate for you to get an occluder.
