US Patent:

7887574, Feb 15, 2011
Filed:

Dec 23, 2003
Appl. No.:

10/746516
Inventors:

Sean McFerran - Newark CA, US
Assignee:

Scimed Life Systems, Inc. - Maple Grove MN
International Classification:

A61F 2/06
US Classification:

623 111
Abstract:

A self-expanding stent delivery assembly includes an elongate member with a proximal region and a distal region. The distal region has an outer tubular member. A self-expanding stent is disposed within the outer tubular member. Circumferential movement of at least a portion of the proximal region causes relative axial movement between the self-expanding stent and the outer tubular member, deploying the stent. Methods of deploying a self-expanding stent are also described.

International Classification:

A61M 25/00
US Classification:

604525, 604526
Abstract:

Catheters having a pre-shaped tip configuration are disclosed. A catheter in accordance with an illustrative embodiment of the present invention can include an elongated tubular shaft equipped with a distal tip section having a pre-shaped tip configuration that can be used to facilitate tracking of the device through particular locations of the vasculature. The catheter may include a number of features that transition the stiffness and flexibility characteristics of the device and provide a means to radiographically visualize the catheter within the body.

US Patent:

8636714, Jan 28, 2014
Filed:

Sep 22, 2003
Appl. No.:

10/667056
Inventors:

Sean McFerran - Newark CA, US
Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN
International Classification:

A61M 25/00
US Classification:

604523, 604 9601
Abstract:

A microcatheter having a guidewire port that is positioned proximal of the distal end of the microcatheter in order to provide rapid exchange capability.

US Patent:

20110046522, Feb 24, 2011
Filed:

Aug 10, 2010
Appl. No.:

12/853706
Inventors:

Huey Chan - San Jose CA, US
Sean McFerran - Newark CA, US
Stephen Porter - Oakland CA, US
Del Kjos - Pleasanton CA, US
Steve Forcucci - Winchester MA, US
David Constantine - Andover MA, US

Mark Hamm - Lynnfield MA, US
Assignee:

BOSTON SCIENTIFIC SCIMED INC. - Maple Grove MN
International Classification:

A61N 7/00
US Classification:

601 2
Abstract:

In a first embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a capture member. The capture member extends radially inward from an interior surface of the catheter into a lumen of the catheter and is configured to retain the enlarged distal tip so that the enlarged distal tip is temporarily prevented from moving proximally. In a second embodiment, an ultrasound energy delivery assembly includes a waveguide and a sheath covering at least a portion of the waveguide. In a third embodiment, an ultrasound energy delivery assembly includes a waveguide and a dual lumen catheter having a capture member. In a fourth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a proximal waveguide lumen and a proximal guide wire lumen that merges with the proximal waveguide lumen at their respective distal ends to form a distal lumen. In a fifth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a helical spring tip disposed over a distal section of the waveguide. In a sixth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter extruded from a material such as expanded polytetrafluoroethylene. The catheter includes a braided layer having a multi-wire braided section and a single wire braided section formed from a braid wire from the multi-wire braided section.
