Tu avais "spontanément" raison: Temporary embolization may be accomplished by a material that is spherical, biocompatible, bioresorbable, and compressible. However, these properties are not easily achieved in a single embolic microsphere. For example, crosslinking of polymers may be accomplished by using a small molecule crosslinking agent, such as glutaraldehyde. While use of the small molecule crosslinking agent facilitates the desired crosslinking reaction, if the crosslinked polymer is biodegradable and degrades in a body of a patient, some small-molecule crosslinking agents may be toxic or have other adverse effects on cells or tissue in the body of the patient. |
