20090264907 | MEDICAL DEVICE FOR CROSSING AN OCCLUDED BLOOD VESSEL - Medical devices and methods for making and using the same. An example medical device includes a tubular shaft and a crossing member disposed within the tubular shaft. The crossing member may include a loop portion. The methods for using the medical device may include advancing the medical device through the vasculature to a position where at least a portion of the device contacts an intravascular lesion and expanding the loop portion of the crossing device to displace the occlusion. | 10-22-2009 |
20090312828 | Edge Protection via Tapered Balloon Wrap - A stent deployment device is provided with a tapered balloon wrap to protect the edge of a crimped stent during stent deployment. The balloon is wrapped unevenly so that the distal end is looser and has a wider circumference than the proximal end of the balloon. With a stent crimped upon such a balloon, the distal balloon end billows out and covers the distal edge of the stent. This shielding billow prevents the stent edge from becoming damaged or causing harm if the stent is distally impacted while traversing body vessels on the way to the deployment site. | 12-17-2009 |
20100132718 | Occlusion Stent - A device for occluding a target body lumen, comprises a wire structure defining a wire structure lumen extending therethrough and movable between a reduced diameter insertion configuration and an expanded diameter deployed configuration and a basket structure extending across the wire structure lumen and including therein a cell growth promoting agent to promote cell growth across the wire structure lumen to occlude the target body lumen. | 06-03-2010 |
20100217305 | EMBOLIC PROTECTION FILTERING DEVICE THAT CAN BE ADAPTED TO BE ADVANCED OVER A GUIDEWIRE - An improved embolic protection filtering device. In at least some embodiments, an embolic protection filtering device includes a filter wire assembly. The filter wire assembly may include an elongate shaft, a tubular member, and an embolic protection filter. | 08-26-2010 |
20100331955 | ROLLING MEMBRANE STENT DELIVERY SYSTEM - A medical device delivery system, having a rolling retractable sheath covering a medical device mounting region on the system is disclosed. The rolling retractable sheath comprises an inner wall and an outer wall and may be formed of one or more materials, optionally porous. Optionally, a lubricant maybe applied selectively to the interior and exterior walls of the stent. | 12-30-2010 |
20110301635 | EMBOLIC PROTECTION FILTERING DEVICE THAT ACAN BE ADAPTED TO BE ADANCED OVER A GUIDEWIRE - An improved embolic protection filtering device. In at least some embodiments, an embolic protection filtering device includes a filter wire assembly. The filter wire assembly may include an elongate shaft, a tubular member, and an embolic protection filter. | 12-08-2011 |
20130274735 | RENAL DENERVATION AND STIMULATION EMPLOYING WIRELESS VASCULAR ENERGY TRANSFER ARRANGEMENT - Devices, systems, and methods provide for intravascular or extravascular delivery of renal denervation therapy and/or renal control stimulation therapy. Wireless vascular thermal transfer apparatuses and methods provide for one or both of production of current densities sufficient to ablate renal nerves and terminate renal sympathetic nerve activity, and production of current densities sufficient to induce endothelium dependent vasodilation of the renal artery bed. A common apparatus may be used for both renal ablation and control of renal function locally after renal denervation. | 10-17-2013 |
20140039532 | MEDICAL DEVICE INCLUDING STRUCTURE FOR CROSSING AN OCCLUSION IN A VESSEL - An medical device, such as a guidewire, catheter, or the like, that includes an elongated tubular member that includes a plurality of angled slots defined in at least a distal section thereof. The plurality of angled slots can form a generally spiral shaped pattern about the longitudinal axis of the tubular member, and can be useful, for example, in aiding a user of the device in crossing an occlusion in a vessel of a patient. In some embodiments, the distal section of the tubular member may have an outer diameter that is greater than the outer diameter of a proximal section of the tubular member. In some embodiments, a proximal section of the tubular member may include a plurality of slots defined therein, for example, that may be configured to increase the lateral flexibility of the tubular member. | 02-06-2014 |
