| 20110066074 | Filter for Fine Needle Biopsy - A biopsy needle comprises a first lumen open to a tissue penetrating distal tip of the needle for receiving a tissue sample therein and a second lumen in combination with a filter separating the first and second lumens from one another, the filter being configured to permit fluids to pass therethrough while preventing the sampled tissue from passing therethrough. | 03-17-2011 |
| 20110071429 | EUS-FNA Stylet Withdrawal into Handle - A medical device comprises a needle configured for insertion into a body and defining a needle lumen extending therethrough from a proximal end opening to a distal end opening and a handle connected to a proximal end of the needle and including a stylet receiving lumen therein, the stylet receiving lumen being open to a proximal end of the needle lumen. The medical device also comprises a stylet movable between a retracted configuration in which a distal end of the stylet is received within the stylet receiving chamber and an extended configuration in which the distal end of the stylet is received within the distal opening of the needle lumen sealing the distal opening, wherein, when withdrawn proximally into the stylet receiving lumen, the stylet is coiled within the chamber. | 03-24-2011 |
| 20110077622 | DELIVERY SYSTEM HAVING STENT LOCKING STRUCTURE - A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and a locking mechanism for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft such that the proximal end of the stent is positioned proximal of the distal end of the elongate shaft. The locking mechanism includes an engaging feature of the elongate shaft which engages a portion of the stent such that the stent may be selectively coupled to the elongate shaft through rotational motion of the elongate shaft relative to the stent. In some instances, the engaging feature of the elongate shaft may be a tab which extends into an opening of the stent. | 03-31-2011 |

| 20080243176 | GUIDE TUBE SYSTEMS AND METHODS - Disclosed herein are various systems and methods for guiding, supporting, and/or housing instruments. One exemplary system includes a guide tube having a manipulation section and mated with rails carrying instrument control members. Moving the rails with respect to the guide tube, or another point of reference, can control movement of the manipulation section. | 10-02-2008 |
| 20080287740 | METHODS AND DEVICES FOR TRAVERSING AN ANATOMIC WALL - Disclosed herein are various systems and methods for traversing an anatomic wall. A system can include a port that mates with an anatomic wall and provides a lumen for the passage of a guide tube of a transluminal device. The port can inhibit the passage of biological materials through the anatomic wall. Further described herein are methods for implanting the port and/or for inserting the transluminal device into a body cavity. | 11-20-2008 |
| 20090177114 | Echogenic needle aspiration device - An echogenic needle aspiration device. In one embodiment, the device includes an echogenic needle, the needle including a tubular sidewall having a non-circular transverse cross-section over at least a portion of its length. The non-circular cross-sectional shape of the needle may be provided, for example, by radially spacing one or more straight, longitudinally-extending fins, ribs or other projections about the periphery of the needle and/or by providing the needle with a polygonal cross-sectional shape. | 07-09-2009 |
