  • Publication number: 20050125011
    Abstract: Catheter based systems and methods for securing tissue including the annulus of a mitral valve. The systems and methods employ catheter based techniques and devices to plicate tissue and perform an annuloplasty.

  • Publication number: 20040191215
    Abstract: Compositions for attracting specific cells to an in vivo site and for stimulating the attracted cells and local resident cells to achieve a desired therapy are described. In one embodiment, a composition for initiating and promoting repair and regeneration of tissue is described. In another embodiment, a composition for inducing a cytotoxic response to tumor cells is described. The compositions are comprised of drug reservoirs containing one or more therapeutic agents effective (1) to attract one or more desired cells to the tissue site; (2) to stimulate activity, e.g., proliferation, differentiation, and/or release of biological factors that promote a desired activity, in the attracted cells; and (3) to prolong survival of the attracted cells and, if desired, local resident cells. A device for administering the composition at a desired site is also described.

  • Patent number: 6068629
    Abstract: A steerable electrophysiology catheter includes a shaft having a distal ablation segment with one or more electrodes coupled to a source of electrical energy by a connector extending through the shaft. The distal ablation segment of the shaft is movable between a collapsed configuration sized for percutaneous introduction into the patient and/or endoluminal delivery to the target site and an expanded configuration, in which the distal ablation segment forms a substantially continuous surface transverse to the shaft axis for engaging the heart tissue and creating a linear lesion thereon. The catheter includes one or more force element(s) positioned to apply an axial force between the distal and proximal ends of the ablation segment. The force element(s) provide a sufficiently uniform force against the distal ablation segment to establish continuous contact pressure between the electrodes and the patient's heart tissue.
