  • Publication number: 20150305892
    Abstract: A bodily lumen, such as a blood vessel, can be treated by forming a structural support in situ within the bodily lumen. This can be done by ejecting a formulation that includes a polymer that solidifies over a period of time, such as due to DMSO exchange or photocrosslinking. This can also be done by cooling a formulation until it freezes in situ. The structural support can also be made from a plaque which is already present in the bodily lumen. The plaque can be compressed by a balloon catheter and cooled so that it hardens and thereby forms the structural support. The bodily lumen can also be treated using a preformed structural support made of ice, for example frozen isotonic saline, or a fast degrading polymer, such as PEG. The preformed support is created outside of the bodily lumen, and then transported on a catheter to the treatment zone.

  • Patent number: 9161852
    Abstract: A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes one or more balloon pressurization steps. The balloon pressurization steps are selected to enhance scaffold retention to the balloon while retaining, at least partially, the original balloon folds as the balloon is pressurized and de-pressurized within a crimper head. By at least partially retaining the original balloon folds, a uniformity of scaffold expansion by the balloon is improved.

  • Publication number: 20150289875
    Abstract: Medical devices and methods for forming an arteriovenous (AV) fistula include a stent having an arterial tubular portion and vein supporting tongue connected by a pre-shaped connector and a venous frustoconical stent having a distal end for maintaining a take-off angle for the venous portion of the AV fistula. Also disclosed is an angled balloon for assisting with the formation of the AV fistula. The medical devices disclosed herein support an AV fistula formation having a desired take off angle of about 30 degrees, or between about 15 and 45 degrees.

  • Publication number: 20150096491
    Abstract: A system and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and a dispenser positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A guide maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by displacing the expandable member relative to the at least one outlet.

  • Patent number: 8951595
    Abstract: A drug delivery balloon is provided, the a balloon having an outer surface, and a tunable coating disposed on at least a length of the balloon surface. The tunable coating includes a first therapeutic agent and a first excipient, and can include a second therapeutic agent and a second excipient. The first and second therapeutic agents have different dissolution rates during balloon inflation and therefore provide a coating that is tunable.
