20120116503 | COATED MEDICAL DEVICES AND METHODS - The invention relates to medical device systems that include a delivery instrument comprising a sheath having an abluminal surface and a luminal surface; a radially-expandable frame disposed at least partially within the sheath, the frame having an abluminal surface at least partially in contact with the luminal surface of the sheath, and a luminal surface defining a sub-stantially cylindrical lumen; and a fine powder coating disposed on at least one of the abluminal surface of the frame and the luminal surface of the sheath. The invention also relates to methods of manufacturing, loading, and delivering the coated medical devices. | 05-10-2012 |
20130131779 | SILANE BONDED MEDICAL DEVICES AND METHOD OF MAKING SAME - A method for bonding a graft material to a support element employing a silane coupling agent, and a medical device obtainable by said method. A medical device including a graft material bound to a support element by a plurality of silane linkages is also described. | 05-23-2013 |
20130211497 | MEDICAL PROSTHESES HAVING BUNDLED AND NON-BUNDLED REGIONS - The present embodiments provide an endoluminal prosthesis, such as a stent-graft, having a relatively low delivery profile. In one embodiment, the prosthesis comprises a membrane, and at least one stent having contracted and expanded states, where the stent is coupled to the membrane and maintains patency in the expanded state. The prosthesis further may comprise selectively oriented axial and/or circumferential fibers arranged at predetermined locations along the length and circumference of the prosthesis. An increased population density of the circumferential and/or axial fibers may be provided in areas in which the at least one stent portion is attached to the membrane, or in areas of higher physiological loads imposed upon the endoluminal prosthesis. Selectively orienting axial fibers and circumferential fibers at predetermined locations along the length and circumference of the prosthesis, but not continuously along the entire prosthesis, significantly reduces delivery profile due to the reduction in graft material. | 08-15-2013 |
20140081386 | ENDOLUMINAL PROSTHESIS - An endoluminal prosthesis for placement within a body vessel may include a tubular support structure including a proximal end segment, a distal end segment, an intermediate segment positioned between the proximal end segment and the distal end segment, a lumen extending longitudinally within the support structure, a luminal surface, and an abluminal surface opposite the luminal surface. The prosthesis may include a first layer of nonwoven electrospun fibers positioned on the luminal surface of the support structure. The prosthesis may include a second layer of nonwoven electrospun fibers positioned on the abluminal surface of the support structure. At least one of the proximal end segment or the distal end segment of the support structure may be encapsulated within a covering including the first layer of nonwoven electrospun fibers and the second layer of nonwoven electrospun fibers. The intermediate segment of the support structure may be unencapsulated within the covering. | 03-20-2014 |
20140277052 | TRI-FLUTED VASCULAR ACCESS NEEDLE - A needle disclosed herein may include an elongate body extending between a proximal end and a distal end with a central longitudinal axis defined by the body, where the distal end includes a single sharp point along the central longitudinal axis and defining a distal end terminus three longitudinal fluted surfaces converging at the distal end terminus; and three longitudinal beveled cutting edges defining borders between the fluted surfaces and converging at the distal end terminus. Needle embodiments may include one or more ports open into and/or proximal of the fluted surfaces and communicating with one or more longitudinal needle lumens. | 09-18-2014 |
20140315847 | DRUG ELUTING GRAFT CONSTRUCTS AND METHODS - The present invention provides, in certain aspects, medical graft products that incorporate multiple drug depots in and/or on the products. One such product is a sheet graft construct, for example for tissue support that includes a sheet graft material with a plurality of drug depots. The drug depots can be hardened deposits formed directly onto the sheet graft material and/or can be capable of eluting a drug for a minimum of 72 hours. | 10-23-2014 |
20150133973 | Thrombectomy Catheter With Flow Directing Mechanism - A thrombectomy catheter includes a catheter body having first and second lumens formed therein, and a flow directing mechanism upon a distal body end forming a channel for conveying fluid between an outlet and an inlet fluidly connected with the first and second lumens. The channel axially and circumferentially advances about the catheter body, and is positioned between the outlet and inlet such that fluid conveyed by the channel enters a suction stream flowing to the inlet and entraining material of disrupted thrombus. | 05-14-2015 |
20150257760 | IMPLANT FOR FACILITATING SUTURELESS SIDE-TO-SIDE ARTERIOVENOUS FISTULA CREATION AND MAINTAINING PATENCY - An anastomosis device for facilitating sutureless side-to-side arteriovenous fistula creation and maintenance of patency thereof is presented. The device comprises two device halves each containing an anastomosis window which is in fluid connection with an interior lumen of the device. Further, the device comprises a pair of vessel joining portions in which the bounds of the fistula are created. The invention also has an embodiment wherein a method of joining a vein and an artery in order to create a fistula is presented. | 09-17-2015 |
20150257906 | EXTRAVASCULAR IMPLANT FOR FACILITATING SUTURED SIDE-TO-SIDE ARTERIOVENOUS FISTULA CREATION AND MAINTAINING PATENCY - An extravascular anastomosis device for facilitating side-to-side arteriovenous fistula creation and maintenance of patency thereof is presented. The device comprises two device halves each containing an anastomosis window which is in fluid connection with an interior space of the device. Further, the device comprises a pair of vessel capture spaces in which portions of the vessels to be joined are captured. The invention also has an embodiment wherein a method of joining a vein and an artery in order to create a fistula is presented. | 09-17-2015 |
