摘要:
Radiopaque polymer compositions and methods for making the compositions are provided. These radiopaque polymer compositions include shape memory polymer compositions comprising a crosslinked polymer network, the network comprising a first repeating unit derived from a monofunctional iodinated monomer and a second repeating unit derived from a multifunctional non-iodinated monomer wherein neither of the two monomers is fluorinated. Devices formed from radiopaque polymer compositions are also provided.
摘要:
A pharmaceutically acceptable implant system comprising a collection of pharmaceutically acceptable, covalently-crosslinked hydrogel particles having a radioopaque agent covalently attached to a plurality of the particles in the collection, with the radioopaque agent being present in the collection at a concentration of at least about 0.1% w/w. The implantable materials may be used, for instance, in an iatrogenic site and for fiducial marking.
摘要:
The present invention relates to a class of compounds and to diagnostic compositions containing such compounds where the compounds are iodine containing compounds. More specifically the iodine containing compounds are chemical compounds containing a hydrophilic aliphatic central moiety allowing for the arrangement of three iodinated phenyl groups bound thereto. The invention also relates to the use of such diagnostic compositions as contrast agents in diagnostic imaging and in particular in X-ray imaging and to contrast media containing such compounds.
摘要:
The present invention discloses a radiographic contrasting agent containing multiple aromatic groups, each of which is substituted with at least three halogen atoms. The radiographic contrasting agent can initiate a polymerization process. The present invention also discloses a radio-opaque polymeric material that comprises a biodegradable polymer having at least one radiographic contrasting moiety covalently attached thereto. The radio-opaque polymeric material provides enhanced contrasting intensity in radiographic imaging. The radio-opaque polymeric material can be applied on at least a portion of one surface of a medical device. The radio-opaque polymeric material can also be used to construct a medical device, a component thereof, or a portion of a component thereof.
