  • Patent number: 11229777
    Abstract: A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty which microperforates the plaque with small sharp spikes acting as serrations for forming cleavage lines or planes in the plaque. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment enables subsequent angioplasty to be performed at low balloon pressures of about 4 atmospheres or less, reduces dissections, and avoids injury to the arterial wall. The subsequent angioplasty may be performed with a drug-eluting balloon (DEB) or drug-coated balloon (DCB). The pre-angioplasty perforation procedure enables more drug to be absorbed during DEB or DCB angioplasty, and makes the need for a stent less likely. Alternatively, any local incidence of plaque dissection after balloon angioplasty may be treated by applying a thin, ring-shaped tack at the dissection site only, rather than applying a stent over the overall plaque site.

    Abstract: A system for replacing a heart valve of a patient. The system includes a delivery device and a prosthetic heart valve. The system is configured to be transitionable between a loaded state, a partially deployed state and a deployed state. In the loaded state, the prosthetic heart valve engages a coupling structure and is compressively retained within a primary capsule, which constrains the prosthetic heart valve in a compressed arrangement. In the partially deployed state, the prosthetic heart valve engages the coupling structure and is compressively retained within a secondary capsule, which constrains the prosthetic heart valve to a partially deployed arrangement. The partially deployed arrangement is less compressed than the compressed arrangement and less expanded than a deployed arrangement. In the deployed state, the primary and secondary capsules are retracted from over the prosthetic heart valve, which expands to the deployed arrangement and is released from the coupling structure.

  • Patent number: 9861726
    Abstract: A method for coupling a body conduit to tissue is provided. The method includes engaging an implant about an outer surface of a catheter. The implant receives a bioactive agent having tissue growth properties. The method involves inserting the catheter through the body conduit and into a tissue opening across a resected area, positioning the implant in the resected area, inflating a balloon to anchor the catheter within the tissue opening such that the implant bridges the body conduit and the tissue opening across the resected area, and maintaining the catheter and the implant in vivo to enable the bioactive agent to secure the implant in the resected area to permanently bridge the body conduit and the tissue opening.

  • Patent number: 9669134
    Abstract: Provided herein are methods for treating an individual having (suffering from) an acute myocardial infarction and drug eluting stents useful for treating such individuals. These methods include treating an individual by introducing, such as by surgically inserting, at a site of an acute coronary artery occlusion upstream of the site of acute myocardial infarction, a drug eluting stent (DES) that is capable of eluting from 25 pg to 950 pg of IGF-1 directly into the coronary circulation. The treatment is specifically directed to stimulation of repair or survival of damaged cardiac muscle or left ventricular remodeling.
