20080262470 | CATHETER HAVING A READILY BONDABLE MULTILAYER SOFT TIP - A balloon catheter having a soft distal tip member having a non-tacky inner (liner) layer material and a soft flexible outer layer material, with both materials being readily thermally bondable to the catheter balloon. | 10-23-2008 |
20090259289 | METHOD OF STENT MOUNTING TO FORM A BALLOON CATHETER HAVING IMPROVED RETENTION OF A DRUG DELIVERY STENT - A method of mounting a drug delivery stent on a balloon of a balloon catheter. The method securely mounts the drug delivery stent on the balloon without damaging the drug delivery layer of the stent. In one embodiment, the method generally comprises positioning a drug delivery stent on a balloon of a balloon catheter, and positioning the balloon with the drug delivery stent thereon within a polished bore of a mold formed at least in part of a metallic material. The balloon is pressurized and heated within the mold as the mold radially restrains the stent from expanding, to mount the stent on the balloon without damaging the drug delivery layer of the stent. | 10-15-2009 |
20130136847 | MANUFACTURING PROCESSES FOR MAKING MEDICAL DEVICES HAVING A COATING GRADIENT - Methods for forming a “coating gradient” on medical devices, such as a balloon catheter or guidewire are disclosed. The balloon portion of the catheter could have a protective covering initially placed over it to prevent the balloon from receiving a first hydrophilic coating. After a first hydrophilic coating is applied to the catheter, the protective covering can be removed exposing the uncoated surface of the balloon. Next, after the protective covering has been removed, a second hydrophilic coating could be applied to the catheter. A guidewire having less lubricity at the distal end portion of the guidewire than the shaft portion which extends proximally away from the distal end section can be created. The method includes the application of a first hydrophilic coating on the elongated shaft and distal shaft section of the guidewire. This first hydrophilic coating is then allowed to cure. Next, the first hydrophilic coating is removed from a portion of the distal shaft section of the guidewire. After the first coating has been removed, a second hydrophillic coating can be applied to the elongated shaft and distal shaft section of the guidewire. The second hydrophilic coating can be allowed to cure. | 05-30-2013 |
20130138038 | CATHETER HAVING A READILY BONDABLE MULTILAYER SOFT TIP - A balloon catheter having a soft distal tip member having a non-tacky inner (liner) layer material and a soft flexible outer layer material, with both materials being readily thermally bondable to the catheter balloon. | 05-30-2013 |
20140074020 | SOFT TIP BALLOON CATHETER - Method for fabricating a balloon catheter including providing an inner tubular member having a distal section and a distal end with a lumen extending therein and forming a balloon having a distal leg with a first segment having a first diameter and a first wall thickness and a second segment having a second wall thickness. The second diameter is greater than the first diameter and the first wall thickness is greater than the second wall thickness. The distal end section of the inner tubular member can be positioned in the balloon and bonded to the first segment while reducing the diameter of the second segment. Method also provided for fabricating a multilayer balloon catheter including removing at least a portion of an outer layer from the distal leg of the balloon. | 03-13-2014 |
20140276401 | Catheter Shaft and Method of Forming Same - Elongate, flexible catheter includes an elongated shaft having a proximal end, a distal end, and a lumen defined therein. The shaft includes a tubular member having an outer layer and an inner layer. The outer layer includes a first polymer selected from the group consisting of nylon 12, polyether block amide, and combinations thereof. The inner layer includes a second polymer having a heat deflection temperature greater than about 53° C. selected from the group consisting of nylon 11, nylon 6, nylon 6,6, nylon 6,12, polyamide-imide, polyetherimide, polypropylene, polyethylene terephthalate, polybutylene terephthalate, polyethereetherketone, and combinations thereof. Method of making an elongate, flexible catheter is also provided. | 09-18-2014 |
20140358176 | Soft Tip Balloon Catheter - Method for fabricating a balloon catheter including providing an inner tubular member having a distal section and a distal end with a lumen extending therein and forming a balloon having a distal leg with a first segment having a first diameter and a first wall thickness and a second segment having a second wall thickness. The second diameter is greater than the first diameter and the first wall thickness is greater than the second wall thickness. The distal end section of the inner tubular member can be positioned in the balloon and bonded to the first segment while reducing the diameter of the second segment. Method also provided for fabricating a multilayer balloon catheter including removing at least a portion of an outer layer from the distal leg of the balloon. | 12-04-2014 |
20150088063 | CATHETER HAVING A READILY BONDABLE MULTILAYER SOFT TIP - A balloon catheter having a soft distal tip member having a non-tacky inner (liner) layer material and a soft flexible outer layer material, with both materials being readily thermally bondable to the catheter balloon. | 03-26-2015 |
