摘要： Techniques and features for reduction of air potentially released during endoluminal device (e.g., thoracic aortic stent-graft device) deployment. Also addressed are methods for quantifying efficacy of pre-treatment techniques and features for reducing said air. Such air reduction can help reduce risk of air embolization during device (e.g., implant, such as stent-graft) deployment which could potentially decrease the risk of negative effects from such embolization.

摘要： An implant delivery system having an implant-pusher junction that has improved flexibility due to a shortened heater and tapered marker band. The heater capsule includes a coil having a complex shape made possible through additive manufacturing. The complex shape generates increased heat over a shorter length when compared to traditional linear coils. The marker band includes a tapered end that allows the implant to pivot relative to the pusher.

摘要： Disclosed herein are expandable introducer sheaths and methods of making and using the same. The sheaths minimize trauma to a patient's vasculature by allowing for temporary expansion of a portion of the sheath to accommodate passage of a delivery system for a cardiovascular device, then return to a non-expanded state after the passage of the device. The sheath includes an elongated annular member having longitudinally extending channels that facilitate the sheath's temporary expansion. The channels are positioned in such a way that, upon expansion, they enable the movement of protruding contact surfaces toward the inner and outer surfaces of the annular member, reducing friction between the surface and the passing device. Some embodiments of the expandable sheath include an elastic outer layer that pushes the protruding contact surfaces back towards their original positions after the passage of the device.

摘要： Systems and method for delivering and deploying an expandable stent to treat Intracranial atherosclerotic disease (ICAD) involving large and medium-sized blood vessels. The disclosed systems include a catheter, a shaft comprising a distal end disposed within the catheter, an expandable stent comprising a proximal end and a distal end, wherein the shaft is coupled to the expandable stent and the shaft is disposed within the expandable stent, and a plurality of struts, wherein a first end of each strut is coupled to the shaft and a second end of each strut is coupled to the expandable stent. Longitudinal movement of the shaft relative to the expandable stent extends the plurality of struts radially outward and expands the expandable stent, similar to umbrella. The plurality of struts provides radial force to the expandable stent in an expanded configuration to the vessel walls of the patient.

摘要： Disclosed is a method, apparatus, and kit for assisting the expansion of a self-expanding stent, especially within highly curved or tortuous blood vessels. An elongated pusher having an expandable distal mesh portion can be positioned within a self-expanding stent, expanding during delivery to provide extra expansion force to the stent to ensure the stent properly expands.

摘要： A percutaneous transluminal angioplasty device includes a catheter defining one or more lumens. A filter is coupled to the catheter adjacent a distal end of the catheter, and the filter is movable between an unexpanded and expanded configuration via a filter activation wire that extends through a lumen. An expandable balloon is coupled to the catheter proximally of the filter, and a stent is disposed over at least a portion of the balloon. To deploy the stent to a target site, the filter is first moved into its expanded position via the filter activation wire. Then, the stent is expanded, and the balloon is inflated to expand the stent further radially. The balloon is then deflated, the filter is contracted, and the catheter, balloon, and filter are removed from the body.
