Publication number: 20080281395Abstract: A bifurcated stent having a side branch constructed out of a bioabsorbable material. The side branch comprises one or more bio cells which are flexible and easily deformable when the stent is in the unexpanded state. The bio cells have a locking member which fixedly holds the bio cells in place once the stent assumes the expanded state. The locking member uses oppositely directed hooks or ratchet teeth to prevent contraction in the bio cells once the expanded state is assumed. By having an appropriate alternation between flexibility and rigidity the side branch is flexible enough to deal with the geometric difficulties of bending and deploying a side branch while being fixed and rigid enough to properly support and scaffold a side branch assembly. The deployment of the side branch can be facilitated by the use of a ratcheting device. The side branch can also have a flared shape.Type: ApplicationFiled: May 7, 2007Publication date: November 13, 2008Applicant: Boston Scientific Scimed, Inc.Inventors: Tracee Eidenschink, Todd Bethel, Thomas E. Broome, Gordon J. Kocur, Jens Hegg, Michael P. Meyer

Patent number: 6872216Abstract: An emboli capturing system captures emboli in a body lumen. A first elongate member has a proximal end and a distal end. An expandable emboli capturing device is mounted proximate the distal end of the first elongate member, and is movable between a radially expanded position and a radially contracted position. When in the expanded position, the emboli capturing device forms a basket with a proximally opening mouth. A second elongate member has a proximal and a distal end with a lumen extending therebetween. The lumen is sized to slidably receive a portion of the first elongate member. An expandable delivery device is mounted to the distal end of the second elongate member and is movable from a radially retracted position to a radially expanded position. The delivery device has a receiving end configured to receive the emboli capturing device, and retains at least the mouth of the emboli capturing device in a radially retracted position.Type: GrantFiled: January 17, 2003Date of Patent: March 29, 2005Assignee: SciMed Life Systems, Inc.Inventors: John M.

Publication number: 20040167566Abstract: 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: February 24, 2003Publication date: August 26, 2004Applicant: SCIMED LIFE SYSTEMS, INC.Inventors: Mel R.
