Blood vessels exfoliation

Catheters for Thrombosis Sample Exfoliation in Blood Vessels Using Piezoelectric Polymer Fibers... 

From the results of the experiments described above, it was decided to consider a more realistic scenario. Here, it was assumed that a thrombosis had occurred in a blood vessel, as shown in Figure 18.10 [8, 9, 16]. The tip of a catheter was inserted at the point where a vessel branches off, and cells were exfoliated from the affected area for examination. For this demonstration, a PLLA fiber catheter was used (Figure 18.8) [9], operated according to the following procedure. Firstly, the PLLA fiber catheter was inserted under microscopy...
