Patent number: 9839769Abstract: An expandable sheath assembly includes a support body extending from a proximal end to a distal end. A guide rod is interconnected to the support body and extends between the ends along an axis. A dilator extends from the guide rod for insertion into a body vessel, and a hub is releasable connected to the distal end of the support body. A distal sheath overlays the dilator, and a hemostatic valve is slidably disposed along the axis. A proximal sheath extends from the hemostatic valve and is disposed in surrounding and coaxial relationship with the guide rod. The proximal sheath is concurrently slidable with the hemostatic valve along axis to advance the proximal sheath through the hub and interleave the proximal sheath between the dilator and the distal sheath for lifting the distal sheath from the dilator and effectuating an expansion of the body vessel.Type: GrantFiled: September 4, 2014Date of Patent: December 12, 2017Assignee: FREUDENBERG MEDICAL, LLCInventors: Greg Furnish, Anthony Appling, Simon Furnish, Asela Indaka Gunasekara, Ben Morris

Patent number: 7758634Abstract: A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening. The secondary stent section has an unexpanded configuration with a first length and an expanded configuration with a second length where the first length is less than the second length. The secondary stent section is expanded to the expanded configuration after the primary stent section is expanded to the expanded configuration. The secondary stent section forms a portion of the tubular wall of the primary stent section in the unexpanded configuration.Type: GrantFiled: March 21, 2007Date of Patent: July 20, 2010Assignee: Boston Scientific Scimed, Inc.Inventors: Gregory G. Brucker, Enrique Malaret, Todd Hall, David Byrd, Gerald Hubbs, Gregory Furnish, Josh Barber, Indaka Gunasekara, Benjamin Morris, Valerie Futral, Sava A. Chernomordik, William C.

Patent number: 6695877Abstract: A bifurcated stent comprises a first stent section and a second stent section. Each stent section is expandable from a predeployed state to a deployed state independently from one another. The second stent section having an end engaged to a receiving region of the first stent section.
