Patent number: 8647376Abstract: A balloon fold design for efficient expansion of a side branch assembly in a bifurcated stent. The design involves forming a cup arrangement by folding the radial end of the side branch balloon structure into the luminal end of the side branch balloon structure and then folding the cup down into an orderly discus arrangement. The folding pattern allows for the side branch balloon structure to inflate in a sweeping rotational manner efficiently pushing the side branch assembly petals out and away from the main body of the stent with a low risk of the balloon becoming entangled or damaged by its contact with the petals. The design also allows for the expansion force to be applied at the appropriate time in the optimally needed direction by initially being oriented in a predominantly circumferential direction which is gradually shifting to a predominantly radial direction. In addition, the fold design reduces the overall volume and profile of the side branch balloon structure.Type: GrantFiled: March 30, 2007Date of Patent: February 11, 2014Assignee: Boston Scientific Scimed, Inc.Inventor: Benjamin Arcand

Patent number: 8435261Abstract: Devices, methods and kits which, when installed or used, access, aspire, dilate, insufflate, drain or deliver fluid medicaments to, or place a patency device within a sinus area, such as a maxillary sinus or a maxillary sinus ostium. The device can include a hollow catheter and probe, and can be configured to permit gradual and incremental probe extension. The device can be constructed to enhance the precision and maneuverability within the nasal and sinus passageways, while also accommodating the natural anatomical geometry of a targeted paranasal treatment site. For example, the present treatment and placement device can accomplish access to the maxillary sinus ostium by utilizing an uncinate process to guide a probe tip into the ostium in a retrograde manner. The probe can be slidably, bi-directionally or co-axially positioned within the catheter. A distal portion of the probe can be biased away from a longitudinal axis of the catheter.Type: GrantFiled: July 15, 2010Date of Patent: May 7, 2013Assignee: Regents of the University of MinnesotaInventors: Benjamin Arcand, Joseph E. Hale, Nikhil Murdeshwar, Bryan Rolfes

Patent number: 8402619Abstract: The invention described herein provides for a simple, economical system and method for reducing environmental release of dental amalgamous mercury from teeth caused by cremation of corpses. The invention controls and reduces the amount of mercury released using a pre-crematorial and non-disfiguring system and method. The system of the invention can include a dental containment and applicator delivery system to apply a curable thermal protectant composition onto the teeth. The composition coating significantly inhibits the extent of thermal destruction of the tooth per se including its amalgam filling content.Type: GrantFiled: November 24, 2009Date of Patent: March 26, 2013Assignee: Minnesota Funeral Directors AssociationInventors: Benjamin Arcand, Bryan N.

Patent number: 8225474Abstract: A crimping fixture for crimping a stent onto a balloon of a catheter is disclosed. The crimping fixture includes a flexible elastomeric body having a crimping lumen and one or more inflation lumens extending through the flexible elastomeric body. The flexible elastomeric body is elastically stretched such that a pre-crimped stent may be placed in the crimping lumen. The inflation lumens are then pressurized with a fluid to impart an inward crimping force onto the stent to crimp the stent to a balloon.Type: GrantFiled: May 30, 2008Date of Patent: July 24, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Benjamin Arcand, Ryan Welty
