  • Patent number: 7261875
    Abstract: The present invention concerns a design for dendritic poly(amino acid) polymer carriers, also known as nonlinear polymers, and their applications. These dendritic poly(amino acid) carriers have multiple functional groups at the polymer surface. In addition, they have heterofunctional groups on the poly(amino acid) side chains for drug or diagnostic agent attachment. They are designed to allow sufficient preservation of the binding affinity of the targeting ligand while conjugating therapeutic or diagnostic agents to the polymers. The present invention also describes methods of production of the polymer carriers and methods for the treatment or diagnosis of diseases employing the polymer carriers. The present invention also includes methods to introduce targeting moieties site-specifically to the end of polymer chains.

  • Publication number: 20070196275
    Abstract: Conjugate molecules comprising a ligand bonded to a polymer are disclosed. One such conjugate molecule comprises a ligand bonded to a polymer, a chelating agent bonded to the polymer, and a radioisotope chelated to the chelating agent. The conjugate molecules may be useful in detecting and/or treating tumors or biological receptors. These conjugate molecules may be synthesized without the necessity of preactivation of the ligand using an SCN-polymer-chelating agent precursor. Conjugate molecules incorporating an annexin V ligand are particularly useful for visualizing apoptotic cells. Conjugate molecules incorporating a C225 ligand are particularly useful for targeting tumors expressing EGFR.

  • Publication number: 20060155303
    Abstract: An occlusion method and apparatus. The occluder includes a elastically deformable members and a jacket. The elastically deformable members are secured in spaced relation and extend in arcuate conformation therebetween. The jacket covers at least a portion of the elastically deformable members. The elastically deformable members are configured to become compressed upon application of a force and to recover the arcuate conformation upon removal of the force to occlude a site.

  • Publication number: 20030216772
    Abstract: A coil-type vasoocclusion device (10) for establishing an embolus or vascular occlusion in a human or veterinary patient is adapted for introduction into the patient via a catheter (32). The device (10) first includes a coil (12) having proximal and distal coil ends (16,18) and a coil lumen (20). The device (10) also includes a core (22) disposed in at least part of the coil lumen (20), the core having proximal and distal core ends (24,26). Only one core end (24 or 26) is directly affixed to a respective end (16 or 18) of the coil (12); the other core end (26 or 24) is not directly connected to either end (16 or 18) of the coil (12). The core (22) is preferably nitinol in a superelastic state, being in other than its stress induced, martensitic condition. The device (10) can include a thrombogenic material (38) connected to or carried by the coil (12). The coil (12) is preferably adapted to achieve a suitable secondary shape (60) when deployed from the catheter (32).
