Publication number: 20160317277Abstract: There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the deflector.Type: ApplicationFiled: May 12, 2016Publication date: November 3, 2016Inventors: Judith T. Carpenter, Jeffrey P. Carpenter, David A. Rezac, Jeffrey C. Cerier, Richard C. Fortier, Timothy W. Robinson

Publication number: 20160143756Abstract: An endovascular medical device that, when inserted into a vessel having one or more dilations and one or more narrowings in close proximity, redefines the vessel opening (lumen) along the longitudinal axis of the device, separates that lumen from the excess dilated volume within the dilation, and props open the lumen within the narrowing. The device is constructed in a manner to alter the hemodynamics at the interface between the redefined lumen and excess dilated volume, to facilitate the healing process within the dilated vessel. The device is constructed in a manner to provide sufficient radial force to open a narrowed portion of the vessel, to facilitate flow through the vessel. The device is constructed substantially from bioresorbable materials so as to eventually allow for the return of normal vasomechanics and cyclic wall stresses.Type: ApplicationFiled: November 24, 2015Publication date: May 26, 2016Inventors: David A. Rezac, Aubry E. Shackelford, Amos G. Cruz, Jonathan B. O'Keefe, Jeffrey C. Cerier, Timothy W. Robinson

Patent number: 8323184Abstract: A surgical portal assembly includes a portal member adapted for positioning within a tissue tract and defining a longitudinal axis with leading and trailing ends. The portal member includes at least one longitudinal port for passage of an object. The portal member comprises a compressible material adapted to transition between a first expanded condition to facilitate securing of the portal within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract, and a second compressed condition to facilitate at least partial insertion of the portal within the tissue tract. The portal assembly also includes an elongated member extending through the at least one longitudinal port and mechanically couplable to the portal member adjacent the leading end thereof.Type: GrantFiled: March 8, 2010Date of Patent: December 4, 2012Assignee: Covidien LPInventors: Heidi Spiegal, Gregory G.
