Modification of Tissue with Polymers In Situ
Researchers
are currently developing
methods for masking tissue from adhesive cell interactions by
attaching polymer segments to the tissue surface. The attachment
process is performed under conditions and in periods that make
this technique amenable to clinical application. One of the first
targets for applying this approach has been to modify damaged
arterial tissue to prevent platelet deposition. In coronary balloon
angioplasty acute platelet deposition at the site of balloon expansion
is problematic, leading to complications in both the short term
(acute vessel closure) and long term (as a possible contributor
to restenosis). Researchers are evaluating the ability of our
technique to block platelet deposition following vascular damage
in both in vitro and in vivo models of vascular damage and have
reported encouraging results.
