20150245936 | Stent Delivery Catheter With Balloon Control Bands - A stent delivery catheter including a catheter tubing defining a lumen therethrough, a balloon disposed near a distal end of the catheter tubing and moving between deflated and inflated states, and proximal and distal balloon control bands concentrically arranged around respective proximal and distal end portions of the balloon. The proximal balloon control band has a proximal end located proximally of a proximal end of the balloon and a distal end located adjacent a proximal end of a received unexpanded stent. The distal balloon control band has a proximal end located adjacent a distal end of the received unexpanded stent and a distal end located distally of a distal end of the balloon. The balloon control bands each have a diametric cross-section larger than the balloon in an uninflated state and the unexpanded stent received over the balloon to impede axial movement of the unexpanded stent off of the balloon. | 09-03-2015 |
20150238338 | Preventing Embolization of Drug Eluting Stents - A balloon disposed near a distal end of the catheter tubing and moving between deflated and inflated states, and proximal and distal stent retention bands concentrically arranged around respective proximal and distal end portions of the balloon. The proximal stent retention band has a distal end located within 2 mm of the proximal end of a stent coaxially received by the balloon and the distal stent retention band has a largest diameter within 2 mm of the distal end of the stent received by the balloon. | 08-27-2015 |
20120158116 | Means and Method for Preventing Embolization of Drug Eluting Stents - A balloon disposed near a distal end of the catheter tubing and moving between deflated and inflated states, and proximal and distal stent retention bands concentrically arranged around respective proximal and distal end portions of the balloon. The proximal stent retention band has a distal end located within 2 mm of the proximal end of a stent coaxially received by the balloon and the distal stent retention band has a largest diameter within 2 mm of the distal end of the stent received by the balloon. | 06-21-2012 |
20120150271 | BUDDY WIRE FOR THE CORONARY ARTERIES - A buddy wire guide wire has a wire section for guiding a catheter to a particular site in the human body. The buddy wire guide wire has a distal section with a distal end and an opposing proximal end. The wire section is attached to the proximal end of the distal section with the distal section being placed coaxially around the shaft of some existing medical device which has been inserted into the human body. The distal section permits the buddy wire to be advanced into the human body over the medical device by using the medical device as a guide. | 06-14-2012 |
20120041469 | REVASCULARIZATION DEVICE WITH INTEGRATED DISTAL EMBOLI PROTECTION - A percutaneous system to open a stenosed vessel has a catheter for insertion into a vessel. An expandable filter mechanism is within a deployable sheath for expansion against a vessel wall when the sheath is displaced by a first displacement distance. A stenosis opening mechanism is within the deployable sheath and is radially expandable near the expandable filter mechanism with the stenosis opening mechanism being expandable against the stenosis when the stenosis opening mechanism is located within the vessel in longitudinal alignment with the stenosis following displacement of the sheath by a second displacement distance. Radiopaque markers align the stenosis opening mechanism with the stenosis. | 02-16-2012 |
20110301695 | OPTIMUM COATINGS FOR VASCULAR STENTS - Disclosed is a stent that allows rapid coverage of the stent's luminal surface with endothelial cells while eluting enough anti-restenosis drug from the stent's abluminal surface to eliminate restenosis. A delay in the release of the anti-restenosis drug from the abluminal surface of the stent struts is created by a drug-free biodegradable polymer that covers that abluminal surface of the stent The anti-restenosis drug being only on the abluminal surface of the stent and the release of that drug being delayed by the outer polymer covering of that abluminal surface allows endothelial cells to have unconstrained mitosis so that they quickly cover the stent's luminal surface. It is further conceived to cover the luminal surface of the stent with an anti-thrombogenic coating such as carbon to further encourage endothelial cell coverage while deterring the deposition of platelets. | 12-08-2011 |
20110301684 | SYSTEM AND METHOD FOR PERFORMING ANGIOGRAPHY AND STENTING - An integrated catheter system for performing angiography on a human patient, the integrated catheter system consisting of an angiographic catheter onto which a thin-walled sheath is co-axially mounted. The angiographic catheter having an essentially straight and elongated proximal section in the form of a cylindrical shaft that is surrounded for less than one-half of its length by the thin-walled sheath that has an outer diameter that is less than 0.25 mm greater than the outside diameter of the angiography catheter. The strength to prevent buckling of the thin-walled sheath being provided by the shaft of the angiographic catheter. The integrated catheter system also being ideal for the placement of stents using small diameter stent delivery systems such as the stent-on-a-wire system. | 12-08-2011 |
20110208287 | Stent Delivery Catheter With Balloon Control Bands - A stent delivery catheter including a catheter tubing defining a lumen therethrough, a balloon disposed near a distal end of the catheter tubing and moving between deflated and inflated states, and proximal and distal balloon control bands concentrically arranged around respective proximal and distal end portions of the balloon. The proximal balloon control band has a proximal end located proximally of a proximal end of the balloon and a distal end located adjacent a proximal end of a received unexpanded stent. The distal balloon control band has a proximal end located adjacent a distal end of the received unexpanded stent and a distal end located distally of a distal end of the balloon. The balloon control bands each have a diametric cross-section larger than the balloon in an uninflated state and the unexpanded stent received over the balloon to impede axial movement of the unexpanded stent off of the balloon. | 08-25-2011 |
20110093059 | HYBRID STENT WITH HELICAL CONNECTORS - The present invention is a hybrid stent design using half-slot circumferential sets of strut members with short (<1.5 mm) slot length that has minimal fish scaling and excellent stent retention and flexibility. These half-slot circumferential sets of strut members are connected one to the other with helical connectors similar to those of the Palmaz stent. One important difference in the design of the stent of the present invention is that the helical connectors are attached to every other crown (rather than connected to every crown) to further improve stent flexibility. By appropriately varying the strut width of both the connected and unconnected curved crowns to be greater at the center than at their ends, an increased radial strength can be provided for a given maximum strain that is imparted to the stent when it is expanded to its maximum diameter. | 04-21-2011 |
