20140031925 | SYSTEMS AND METHODS FOR TRANSCERVICAL AORTIC VALVE TREATMENT - Devices and methods are configured to allow transcervical or subclavian access via the common carotid artery to the native aortic valve, and implantation of a prosthetic aortic valve into the heart. The devices and methods also provide means for embolic protection during such an endovascular aortic valve implantation procedure. | 01-30-2014 |
20140058414 | SUTURE DELIVERY DEVICE - A suture-based vessel closure device can perform the dilation of an arteriotomy puncture and does not require previous dilation of the arteriotomy puncture by a separate device or by a procedural sheath dilator. The suture-based vessel closure device can place one or more sutures across the vessel access site such that, when the suture ends are tied off after sheath removal, the stitch or stitches provide hemostasis to the access site. | 02-27-2014 |
20140371653 | Methods and Systems for Establishing Retrograde Carotid Arterial Blood Flow - Interventional procedures on the carotid arteries are performed through a transcervical access while retrograde blood flow is established from the internal carotid artery to a venous or external location. A system for use in accessing and treating a carotid artery includes an arterial access device, a shunt fluidly connected to the arterial access device, and a flow control assembly coupled to the shunt and adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. The flow control assembly includes one or more components that interact with the blood flow through the shunt. | 12-18-2014 |
20150080942 | System and Method for Assisted Manual Compression of Blood Vessel - A device for applying pressure to a region of a person's neck includes a belt having a length sized to fit around the neck and a compression element coupled to the belt. The compression element is sized and shaped to exert a compressive force onto an area of the neck when the belt is tensioned. | 03-19-2015 |

Methods of making and using the abrasive articles are included. | 09-25-2008 |
20080233850 | ABRASIVE ARTICLE AND METHOD OF MAKING AND USING THE SAME - An abrasive article comprises a porous abrasive member, a nonwoven filter medium, a second nonwoven filter medium, and optionally a porous attachment layer. A plurality of openings in the porous abrasive member cooperates with the first nonwoven filter medium to allow the flow of particles from an outer abrasive surface of the porous abrasive member to the second nonwoven filter medium. Methods of making and using the abrasive articles are included. | 09-25-2008 |
20080280541 | ABRASIVE FILAMENT AND BRUSH - An abrasive filament including a matrix of thermoplastic polymer; and a plurality of abrasive particles such as eutectic alumina zirconia particles interspersed throughout at least a portion of the matrix. Abrasive brushes including such abrasive filaments are also disclosed. Methods of deburring a substrate having at least one burr, with a brush, the brush having bristles including eutectic alumina zirconia particles and a matrix of thermoplastic polymer, wherein the method includes the steps of: contacting the substrate with at least one bristle of the brush in a contact region; and inducing relative motion between the substrate and the at least one bristle. | 11-13-2008 |
20100230835 | COMPOSITE POLYMER FIBERS - A composite polymer fiber comprises a polymer filler material and a plurality of polymer scattering fibers disposed within the filler material. At least one of the filler material and the scattering fibers is formed of a birefringent material. The refractive indices of the filler material and the scattering fibers can be substantially matched for light incident in a first polarization state on the composite polymer fiber and unmatched for light incident in an orthogonal polarization state. The scattering fibers may be arranged to form a photonic crystal within the composite fiber. The composite fibers may be extruded and may be formed into a yarn, a weave or the like. If the filler material is soluble, it may be washed out of the yarn or weave, and the scattering fibers may then be infiltrated with a resin that is subsequently cured. | 09-16-2010 |
