    摘要: An animal model for cardiovascular disease comprising one or more vascular plaque lesions formed at selected sites within a vascular segment of a nonhuman mammal. The vascular plaque lesion is formed by administering a hypercholesterolemic diet to the nonhuman mammal, inflicting an injury to the vascular wall at the selected site after a predetermined exposure to the hypercholesterolemic diet, and applying a hydrogel to the injured vascular wall. Another aspect of the invention provides a method for evaluating a test compound for an effect on atherosclerotic lesion formation comprising administering to a nonhuman mammal a hypercholesterolemic diet, and, after a defined period of time, isolating a segment of a blood vessel using a balloon catheter, inflicting an injury to the vascular wall within the isolated segment, and applying a hydrogel within the vascular segment. The method further comprises forming a vascular plaque lesion on the vascular wall at the site of the injury, delivering the test compound to the nonhuman mammal, and monitoring atherosclerotic lesion size and composition at the injured site after a defined period of exposure to the test compound.

    摘要: Methods for treating a patient using therapeutic renal neuromodulation and associated devices, systems, and methods are disclosed herein. One aspect of the present technology is directed. to methods including selectively neuromodulating afferent or efferent renal nerves, One or more measurable physiological parameters corresponding to systemic sympathetic overactivity or hyperactivity in the patient can thereby be reduced. Selectively neuromodulating afferent renal nerves can include inhibiting sympathetic neural activity in nerves proximate a renal pelvis. This can include, for example, neuromodulating via fluid within the renal pelvis. Selectively neuromodulating efferent renal nerves can include inhibiting sympathetic neural activity in nerves proximate a portion of a renal artery or a renal branch artery proximate a renal parenchyma. This can include, for example, neuromodulating via a therapeutic element within the portion of the renal artery or the renal branch artery.

    摘要: A method of recanalizing a chronic total occlusion (CTO) is disclosed. A catheter with a guidewire slidingly received therein is positioned proximally adjacent to the CTO. An occlusion weakening therapy effective to quickly soften and/or loosen the CTO is delivered to the CTO via the catheter. The occlusion weakening therapy includes at least one enzyme and a chelating agent which are selectively deliverable either together or separately depending on the type of material encountered by the guidewire. According to various methods, the enzyme(s) may be delivered if tissue is encountered, the chelating agent may be delivered if calcification is encountered, and both enzyme(s) and chelating agent(s) may be delivered if a fibrous cap is encountered. The distal end of the guidewire may be advanced into the CTO shortly after delivery of the occlusion weakening therapy and is manipulated through the CTO until the guidewire successfully crosses the CTO.
