  • Patent number: 10220192
    Abstract: A bulbous valvuloplasty balloon is described that maintains its bulbous shape in its final deployed configuration along with the method of use for post dilation of a TAVR device. The bulbous balloon has two larger diameter bulb segments located on each side of a smaller diameter waist and can be used to post dilate a TAVR device that has been implanted at the site of a stenotic aortic valve. The post dilation causes deformation of the underlying tissues residing outside of the TARV stent structure.

  • Patent number: 9408951
    Abstract: Nanoparticles can be embedded into a medical device by accelerating them to a speed of between 100 m/s and 1,000 m/s and embedding the particles into a polymer surface of a medical device or a precursor thereof. In some cases, the nanoparticles can be embedded until the nanoparticles accumulate in sufficient number to adhere together to form a coating over the polymer surface. The nanoparticles can provide a conductive pathway, an abrasion resistant surface, a pro-healing surface, and/or an anti-bacterial surface.

  • Publication number: 20130292043
    Abstract: Composite fiber reinforced balloons for medical devices prepared by applying a web of fibers to the exterior of a preformed underlying balloon and encasing the web with a matrix material to form a composite balloon. The fiber web is applied to at least the cone portion of the underlying balloon form. Either the cone portion of the underlying balloon form, or the web fibers applied to said cone portion, or both, have a friction-enhancing material coated thereon.

  • Patent number: 8287937
    Abstract: A coating having a smooth orange peel morphology is formed on an adluminal surface of a stent, concurrently with the formation of a coating having a rough rice grain morphology on an abluminal surface of the stent. During the formation of the two coatings, a mandrel is placed adjacent to the adluminal surface of the stent but does not generally contact the adluminal surface.

  • Publication number: 20120143243
    Abstract: One or more embodiments of the present disclosure include a closure device, a method of making the closure device and a system that includes the closure device for closing an opening in a body lumen. The closure device includes an intravascular anchor for positioning in the body lumen, a suture coupled to the intravascular anchor, the suture to pass through the opening in the body lumen, a fastener joined to the suture, where the fastener moves longitudinally along the suture, and a plug having a first plug segment and a second plug segment. In one or more embodiments, the second plug segment has a hardness greater than the first plug segment, where the suture passes through the plug with the first plug segment between the intravascular anchor and the second plug segment and the second plug segment between the first plug segment and the fastener.

  • Patent number: 7985252
    Abstract: An endoprosthesis includes a plurality of struts defining a flow passage. At least one strut includes (a) a body comprising a bioerodible material and having a thickness and (b) a coating overlying the body. The coating includes a plurality of regions that allow physiological fluids to contact a plurality of corresponding areas of the underlying body when the endoprosthesis is implanted in a physiological environment. The plurality of regions are sized and arranged so that the contacted areas of the body erode substantially through the body in the thickness direction while the coating remains on the body when the endoprosthesis is implanted in the physiological environment.
