20110295364 | APPARATUS AND METHOD OF USING MARKERS TO POSITION STENTS IN BIFURCATIONS - The present invention provides methods and systems for placing stent systems at vascular bifurcations. The systems include a main branch stent having a side opening, optionally including a side structure, with radiopaque fluoroscopic markers about the periphery of the opening. The stent system further includes a side branch stent having radiopaque markers near at least end thereof. The main branch stent is positioned in the main blood vessel lumen using the markers for proper positioning. After deploying the main branch stent, the side branch stent is positioned through an opening within the side branch. Using the markers on both the main branch stent and the side branch stent, proper alignment and positioning of the two stents relative to each other may be achieved. | 12-01-2011 |
20120059401 | DEVICE AND METHOD FOR COMPARTMENTAL VESSEL TREATMENT - An angioplasty balloon having an elastic constraining structure that partially expands with the balloon so that, at maximum balloon inflation, the constraining structure forms a pattern of channels or “pillows” on the balloon. | 03-08-2012 |
20120095397 | BALLOON CATHETER WITH IMPROVED COLUMN STRENGTH AND TORQUE TRANSMISSION - A balloon catheter capable of delivering torque and pushing through obstructions includes a relatively weak balloon segment of a catheter and rotatable asymmetric tip. A reinforcement sleeve increases column strength and torque transmission to push the balloon and rotate the tip to facilitate passage through said obstructions. The tip is preferably asymmetric around its axis, usually being beveled, and the reinforcement slide includes a slide lock mechanism which increases shaft flexibility after balloon deployment. | 04-19-2012 |
20130084916 | PORTABLE TRANSITIONAL IDENTITY DEVICE - A portable transitional identity device can be used with a conventional cell phone or other mobile device using a cellular network to provide access to one or more additional networks, optionally with encryption. | 04-04-2013 |
20130204179 | Methods and Systems for Delivering Substances Into Luminal Walls - Angioplasty and other dilatation devices are provided with scoring elements which incorporate a drug to be delivered to a body lumen, typically a blood vessel.
