International Classification:
A61M 25/16
US Classification:
604523, 604533, 604264
Abstract:
A catheter shaft with an improved manifold bond and methods for making and using the same. The catheter shaft may include a sleeve disposed, for example, near its proximal end.

Stent Delivery Catheter
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.

Microcatheter With Sleeved Guidewire Port
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. The guidewire port includes provisions that permit guidewire access into a lumen of the microcatheter while providing a relatively fluid tight seal at least when the guidewire is not present in the guidewire port.

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.
