Animal Experimental Study of the Fully Biodegradable Atrial Septal Defect (ASD) Occluder
Figure 2
Transcatheter placement of biodegradable ASD occluder (a) retains the guide wire after the model was created; (b) the occluder (indicated by the white arrow) passes through a sheath, and tantalum marker particles can be seen in the front of occluder; (c) unsheathed the left atrial side of occluder (indicated by the white arrow); (d) the release of the left atrial side of occluder, tantalum particles were unsheathed and separated; (e) the release of the right atrial side of occluder, separation of tantalum particles can be seen (see the white oval); (f) after the occluder release, tantalum markers indicate that both of the two discs were well opened (two small white oval).
