Publication number: 20140243948Abstract: 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.Type: ApplicationFiled: May 5, 2014Publication date: August 28, 2014Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Michal Weisman, Michael D.

Patent number: 8702784Abstract: 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.Type: GrantFiled: October 13, 2011Date of Patent: April 22, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Michal Weisman, Eric Schneider, Gary J.

Patent number: 8696732Abstract: 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.Type: GrantFiled: July 25, 2011Date of Patent: April 15, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Gary J.

Publication number: 20120226101Abstract: A handle for a medical device comprises a proximal segment defining a proximal lumen extending therethrough and sized and shaped to receive an endoscopic medical device therein. A medial segment is received within a distal portion of the proximal segment and has an outer diameter smaller than an inner diameter thereof. A medial lumen extends through the proximal segment and is open to the proximal lumen. A distal segment is received within a distal portion of the medial segment and defines a distal lumen extending therethrough open to the medial lumen. The distal segment has an outer diameter smaller than an inner diameter of the medial segment. The medial segment includes a first movement limiting mechanism limiting movement of an endoscopic medical device inserted therethrough along an axis of the distal lumen and a second movement limiting mechanism limiting advancement of an endoscope attached to the distal body portion.Type: ApplicationFiled: September 6, 2011Publication date: September 6, 2012Inventors: Brian Tinkham, Robert Devries, Michal Weisman, Shawn Ryan, Daniel Bacon

Publication number: 20120203325Abstract: Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include a guide member having a proximal portion and a distal portion. A stent may be disposed about the distal portion of the guide member. The stent may have a wall having an opening formed therein. A pusher member may be disposed about the guide member and positioned proximal of the stent. A holding filament may be disposed at the opening and may extend to the proximal portion of the guide member. The holding filament may be configured to releasably secure the position of the stent relative to the pusher member. The holding filament may be releasable from the stent independently of movement of the guide member.Type: ApplicationFiled: November 18, 2011Publication date: August 9, 2012Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Michal Weisman, Jacob Graham, Gary J.

Publication number: 20110071432Abstract: 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.Type: ApplicationFiled: September 23, 2010Publication date: March 24, 2011Inventors: Oscar R.
