Publication number: 20070123913Abstract: Anchoring mechanisms for releasably securing an intravascular device along an elongated member such as a guidewire or catheter. The anchoring mechanism may include an object that can be actuated between an unlocked position and a locked position. In the unlocked position, the anchoring mechanism is slidably and rotationally disposed about the elongated member. In the locked position, the anchoring mechanism is releasably secured to the elongated member, preventing movement thereon. A placement mechanism such as a tubular member can be utilized to actuate the anchoring mechanism between the unlocked and locked positions.Type: ApplicationFiled: January 10, 2007Publication date: May 31, 2007Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Mel Beulke, Thomas Broome, Robert Cassell, John Daniel, Alan Eskuri, James Hansen, Gary Kostur, Douglas Molland, Scott Smith, Jeffrey Vogel, Anthony Vrba

Publication number: 20020049414Abstract: A fluid delivery and extraction device enables the remote transfer of fluid to or from biological tissue. The device comprises an elongated member, a syringe movable relative to the elongated member and a pair of hypodermic needles movable relative to the elongated member.

A steer wire or guide wire can be used to navigate the distal portion within cavernous biological structures, particularly body lumens. The distal portion has at least one retractable hypodermic needle that is configured to pierce the interior surface of a tubular biological structure and transfer fluid to or from the walls of the tubular biological structure. A physician can use a handle or other control mechanism provided at a proximal portion of the device to remotely move the hypodermic needles. A plunger can be used to transfer fluid through the hypodermic needles to or from the syringe.Type: ApplicationFiled: October 3, 2001Publication date: April 25, 2002Inventors: Anthony A.
