Publication number: 20180214291Abstract: A system is provided to effectively position a stent within a vessel. The system includes a delivery catheter and a core wire extend through the catheter. The core wire includes an engaging surface region and a capture member disposed thereon, which cooperate to engage a stent such that the stent is able to be advanced or retracted with the advancement or retraction of the core wire. The engaging surface region and the capture member can generally be configured to engage the stent when a portion of the stent is disposed within the lumen of the catheter, and release the stent when no portion of the stent is within the lumen.Type: ApplicationFiled: March 29, 2018Publication date: August 2, 2018Inventors: Robert Slazas, Juan A.

Publication number: 20180206973Abstract: A vascular flow diverter includes a tubular mesh framework which includes a mesh cover and an opening. The tubular mesh framework is collapsible and configured to expand from a collapsed shape to a tubular shape when the vascular flow diverter is deployed. The mesh cover conforms to the shape of the tubular mesh, is surrounded by the tubular mesh framework, and is less porous than the tubular mesh framework. The opening is located within the mesh cover. A delivery wire passes through the opening in order to guide the flow diverter into place over an aneurysm.Type: ApplicationFiled: January 26, 2017Publication date: July 26, 2018Applicant: DePuy Synthes Products, Inc.Inventors: Juan Lorenzo, Robert Slazas
