US Classification:

600139

Abstract:

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.

International Classification:

A61B 10/02

US Classification:

600565

Abstract:

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.

International Classification:

A61B 10/02

US Classification:

600567

Abstract:

A device for capturing a tissue sample from within a body comprises a needle slidably comprising a needle lumen extending therethrough to a needle opening in the distal end and a stylet slidably received in the needle lumen for movement between an extended position in which a tissue penetrating distal tip of the stylet extends out of the needle opening to penetrate target tissue and a retracted position in which the distal tip of the stylet is received within the needle opening to substantially seal the needle lumen. The stylet further comprises an anchoring feature located proximally of the tissue penetrating distal tip. The anchoring feature comprises a first gripping member including a first proximal facing abutting surface adjacent to a first tissue receiving gap. Movement of the stylet distally out of the needle lumen brings the first gripping member into engagement with surrounding tissue to anchor the stylet at a desired position within the body.

International Classification:

A61M 27/00

US Classification:

604544

Abstract:

A stent delivery system including an elongate shaft of a medical device, a stent selectively coupled to a distal portion of the elongate shaft, and a coupling mechanism for selectively coupling the stent to the elongate shaft by inserting a tab on one of the stent or the elongate shaft into an opening in the other of the stent or the elongate shaft. The tab may be deflected from a first position to a second position to disengage the tab from the opening.

International Classification:

A61F 2/84

US Classification:

623 111

Abstract:

A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and a retention mechanism for selectively retaining the drainage stent on the elongate shaft. The tubular stent is positioned on and surrounding the elongate shaft. The elongate shaft includes a distal tip portion which is deflectable from a first position to a second position, the distal tip portion of the elongate shaft being biased toward the first position. Deflecting the distal tip portion of the elongate shaft from the first position to the second position moves the distal tip portion toward the central longitudinal axis of the tubular stent to allow the stent to be decoupled from the elongate shaft.

International Classification:

A61F 2/04

US Classification:

623 237

Abstract:

A drainage stent delivery system including a stent, a guide catheter, a push catheter, and an outer sheath. The guide catheter extends through the lumen of the stent and the push catheter is disposed over a portion of the guide catheter proximal of the distal end of the stent. The outer sheath is slidably disposed over the push catheter and surrounding at least a portion of the stent. The outer sheath may be actuated from a first position in which a distal portion of the outer sheath surrounds the stent to a second position in which the distal portion of the outer sheath is proximal of the stent. The stent delivery system may also include a retention mechanism for selectively coupling the stent to the outer sheath which may selectively decouple the stent from the outer sheath through rotational and/or translational motion of the outer sheath relative to the stent.
