Patent number: 10966850Abstract: An implantable medical device deployment system is disclosed that employs both a sheath element and a constraint member to protect implantable medical devices during delivery in a body while providing simple, accurate, and reliable device deployment. The delivery system is configured so that loading and deployment forces are not directly related to device diameter, length, or design, thus allowing a more universal delivery system across various delivered device configurations and product lines. The deployment system can provide numerous benefits, include better protection for drug-coated implantable devices.Type: GrantFiled: March 5, 2015Date of Patent: April 6, 2021Assignee: W. L. Gore & Associates, Inc.Inventors: Craig W. Irwin, James D. Silverman

Publication number: 20210052404Abstract: A medical device frame including an undulating frame element defining a series of peaks each defining a longitudinal splay angle, circumferential cant angle, or combinations thereof. In some examples, the series of peaks are non-overlapping when the frame is in an expanded configuration and overlap when the frame is in the collapsed configuration. The longitudinal splay angle and/0 or circumferential cant angle may remain relatively unchanged between the expanded and collapsed configurations (e.g., within about 15%).Type: ApplicationFiled: April 30, 2019Publication date: February 25, 2021Inventors: Craig W. Irwin, James D. Silverman, Tyson J. Skelton

Publication number: 20180193177Abstract: A stent incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are typically web-shaped and result from creating slits or apertures in a covering of graft material applied to the stent and then, for example, applying heat to cause the slits or apertures to enlarge. The remaining graft material forms the interconnecting webs between the adjacent stent elements.Type: ApplicationFiled: March 8, 2018Publication date: July 12, 2018Inventors: Dustin C.

Patent number: 9526641Abstract: The current invention employs tubes that can be constrained and expanded by either axial or torsional strain. By torsionally displacing the tube in a direction counter to the biased helices and angularly displacing the lower angle helix to an angle equal to, but opposite, the starting angle, the tube is expanded diametrically with no significant change in length after expansion of the tube. These tubes find utility in medical and non medical applications.Type: GrantFiled: January 14, 2015Date of Patent: December 27, 2016Assignee: W. L. Gore & Associates, Inc.Inventors: Craig W.

Patent number: 9114037Abstract: An improved tubular structure adapted to increase in diameter upon application of axial force is provided. Increase in diameter is achieved by constructing the tube from multiple layers of material that move relative to each other during axial elongation of the tube. The tube of the present invention can be used both to avoid problems in “necking” found in many prior tube devices, and to provide additional benefits that increases in diameter of the tube during axial elongation can provide. As such, the tube of the present invention may be useful as a manufacturing aid, as a deployment sheath (for example, to deliver medical devices), and in other applications that may benefit from easier tubular sheath removal.Type: GrantFiled: February 6, 2013Date of Patent: August 25, 2015Assignee: W.

Patent number: 8845712Abstract: A deployment sheath for medical devices is provided that includes one or more pleats in its pre-deployment state that are allowed to open during deployment so as to facilitate easier device deployment and sheath removal. Preferably, the sheath is removed by everting it over itself during the delivery process. By orienting the pleats along the length of the sheath, preferably helically around the sheath, the sheath undergoes a predictable enlargement during deployment so as to relieve friction of the everted sheath sliding along itself during deployment. This allows the sheath to be removed with less tension than previous everting sheath constructions and assures more accurate device placement in a patient.Type: GrantFiled: January 15, 2008Date of Patent: September 30, 2014Assignee: W.
