  • Publication number: 20190030285
    Abstract: The present disclosure describes delivery systems for intravascularly delivering one or more interventional devices to a targeted treatment site within a patient's body. A proximal end of a delivery catheter is coupled to a handle. One or more control lines extend from the handle through the delivery catheter to a coupler disposed at or near the distal end of the delivery catheter. Tensioning of the one or more control lines manipulates the coupler to form or adjust a compound curve in the delivery catheter.

  • Patent number: 10099431
    Abstract: Methods of fabricating a polymer scaffold with increased radial strength including steps of elongation or strain of a biaxially oriented tube and annealing or thermal processing of the strained tube at a constant strain are disclosed. The steps of elongation and thermal processing increase axial direction chain orientation and lamellar crystal growth, increase radial strength, and decrease the thickness of the tube. The method allows fabrication of a scaffold with thinner struts which provide sufficient radial strength.

  • Patent number: 10022906
    Abstract: A polymer tube is processed using a solid phase process for improving mechanical characteristics of the tube, including radial strength and stiffness. The tube is made into a scaffold possessing improved mechanical and use characteristics, such as a reduced crimped profile and improved deliverability.

  • Patent number: 8586125
    Abstract: A method of manufacturing an implantable medical device, such as a drug eluting stent, is disclosed. The method includes subjecting an implantable medical device that includes a polymer to a thermal condition. The thermal condition can result in reduction of the rate of release of an active agent from the device subsequent to the implantation of the device and/or improve the mechanical properties of a polymeric coating on the device.

  • Publication number: 20110066222
    Abstract: A stent may be formed from a PLLA tubular polymer construct that is deformed in a blow mold. A desirable polymer morphology resulting in improved stent performance is obtained with a selected radial axial expansion ratio from about 20% to about 70%, a selected radial expansion ratio from about 400% to about 500%, a selected axial rate of deformation propagation at or about 0.3 mm/minute, a selected expansion pressure at or about 130 psi, and a selected expansion temperature that does not exceed 200 deg F. The tubular polymer construct may also be made of PLGA, PLLA-co-PDLA, PLLD/PDLA stereocomplex, and PLLA-based polyester block copolymer containing a rigid segment of PLLA or PLGA and a soft segment of PCL or PTMC.
