20130138219 | BIODEGRADABLE STENTS HAVING ONE OR MORE COVERINGS - The present embodiments provide a medical device comprising a stent framework having proximal and distal regions and a lumen extending therebetween, and which comprises a biodegradable material. A first covering is coupled to at least a portion of an outer surface of the stent framework. When the stent framework is in an expanded deployed configuration, at least a portion of the first covering is disposed adjacent to a target site and fluid flows through the lumen of the stent framework. Further, the stent framework comprises a material that biodegrades a predetermined time after the first covering achieves at least partial remodeling at the target site. In various embodiments, one or more second coverings may be disposed adjacent to the first covering and comprise a material that biodegrades before the stent framework biodegrades. | 05-30-2013 |
20140114254 | SELF-COILING STYLET NEEDLE DEVICE - A medical device includes an elongate single-wire memory-metal body with a complete length that includes a proximal stylet length, an intermediate self-coiling stylet length, and a distal stylet length that is generally straight and non-self-coiling. The moment of force of the self-coiling stylet length is less than the moment of force of the medical endoscopy needle that is resistant to the stylet's self-coiling force. The device may further include being incorporated into an endoscopy needle system where the single-wire stylet body is disposed through a lumen of a medical endoscopy needle. | 04-24-2014 |
20140114255 | SELF-COILING STYLET NEEDLE DEVICE - A medical device includes an elongate single-wire memory-metal body with a complete length that includes a proximal stylet length, an intermediate self-coiling stylet length, and a distal stylet length that is generally straight and non-self-coiling. The moment of force of the self-coiling stylet length is less than the moment of force of the medical endoscopy needle that is resistant to the stylet's self-coiling force. The device may further include being incorporated into an endoscopy needle system where the single-wire stylet body is disposed through a lumen of a medical endoscopy needle. | 04-24-2014 |
20140121677 | Clutched-Gear Handle and System for Fiducial Deployment - Embodiments include a fiducial deployment system with a handle configured for actuation of same. A fiducial may include one or more protuberances configured to engage one or more slots in a needle of the system. The needle may be configured to deliver a plurality of fiducials to a target location in serial fashion, one at a time. In certain embodiments, echogenic placement of fiducials may present certain advantages. The handle includes a clutched-gear actuation mechanism configured for incrementally or otherwise controlled deploying one or more fiducials at a time by advancing a stylet through and/or retracting the body of a slotted needle in which fiducials are disposed with a fiducial protrusion extending into the needle slot, which also includes retaining structures that do not impede the needle lumen. | 05-01-2014 |
20140243844 | RATCHET-SLIDE HANDLE AND SYSTEM FOR FIDUCIAL DEPLOYMENT - Embodiments include a fiducial deployment system with a handle configured for actuation of same. A fiducial may include one or more protuberances configured to engage one or more slots in a needle of the system. The needle may be configured to deliver a plurality of fiducials to a target location in serial fashion, one at a time. In certain embodiments, echogenic placement of fiducials may present certain advantages. The handle includes an actuation mechanism with a toothed rack and actuation member(s) configured for incrementally or otherwise controlledly deploying one or more fiducials at a time by advancing a stylet through and/or retracting the body of a slotted needle in which fiducials are disposed with a fiducial protrusion extending into the needle slot, which also includes retaining structures that do not impede the needle lumen. | 08-28-2014 |
20140357983 | ACCESS NEEDLES AND STYLET ASSEMBLIES - Access needles and methods of using the needles are set forth in this disclosure. The needles can include a handle and a cannula having a proximal end operatively connected to the handle, a distal end, and a lumen extending through the body of the cannula. A protective sheath may surround the cannula. Further, a stylet may be removably disposed within the lumen of the cannula. The stylet includes a piercing tip at a distal end and a flexible body length extending proximally from the piercing tip to the handle. The flexible body of the stylet provides a path of fluid communication through the lumen of the cannula such that a contrast fluid can effectively pass through the lumen of the cannula. Methods of introducing cannulas to target locations within a body of a patient are also set forth in this disclosure. | 12-04-2014 |

20130158546 | ENDOSCOPIC SYSTEMS AND METHODS FOR RESECTION OF TISSUE - The present embodiments provide apparatus and methods for facilitating endoscopic resection of tissue. In one embodiment, the apparatus comprises a first tube having proximal and distal regions, and a working lumen disposed within at least a portion of the distal region. A second tube is disposed circumferentially around at least a portion of the distal region of the first tube. A wire has a distal end that is securely attached to a distal region of the second tube. In use, rotation of the second tube relative to the first tube causes the wire to pass circumferentially over a distal face of the first tube to incise tissue disposed within the working lumen of the first tube. | 06-20-2013 |
20130158673 | Anti-Leakage Prosthesis - A prosthesis and a method for directing flow through a passageway formed between a first bodily lumen and a second bodily lumen are provided. The prosthesis includes a body having a proximal portion, a distal portion and a lumen extending therethrough. The prosthesis also includes a sleeve operably connected to the body at a connected portion. The sleeve has a proximal portion, a distal portion, and a sleeve lumen extending therethrough. At least a portion of the body is positioned within at least a portion of the sleeve lumen and the distal portion of the sleeve is free from connection to the distal portion of the body and extendable away from the body to contact a wall of the first bodily lumen. The sleeve is configured to allow fluid flow through the sleeve lumen from the first bodily lumen to the second bodily lumen. | 06-20-2013 |
20140025149 | METHOD OF PLACING MULTIPLE BILIARY STENTS WITHOUT RE-INTERVENTION, AND DEVICE FOR SAME - A dual lumen catheter may be provided with one or more stents in a stent-deployment lumen and a wire guide disposed through a wire guide lumen. The wire guide may be directed to a target site in a patient body such as a biliary stricture. The catheter may be directed along the wire guide until it is in or adjacent the target site. A distalmost stent may be advanced out a distal side-facing aperture of the stent-deployment lumen into the target site by a pusher member that advances the stent or that holds the stent in place while the catheter is proximally withdrawn from around the stent. With the wire guide remaining substantially in place, the stent-deployment lumen can be reoriented and the steps repeated to place a second (and, if desired, subsequent) stent(s) next to—and generally parallel with—the first stent. | 01-23-2014 |
