Appl. No.:

12/163325

Dennis R. Dietz - Littleton CO, US
Paul N. Latulippe - Chino Valley AZ, US

Assignee:

W. L. Gore & Associates, Inc. - Newark DE

International Classification:

A61B 5/05

US Classification:

600424, 600437, 600439, 600462, 600466

Abstract:

An improved catheter is provided. The catheter may include a deflectable member located at a distal end of the catheter. The deflectable member may comprise an ultrasound transducer array. The catheter may include a lumen extending from a proximal end of the catheter to the distal end. The lumen may be used to deliver an interventional device to a point distal to the distal end of the catheter. The deflectable member may be selectively deflectable in a pivot-like manner through an arc of at least 90 degrees. In embodiments where the deflectable member includes an ultrasound transducer array, the ultrasound transducer array may be operable to image both when aligned with the catheter and when pivoted relative to the catheter. When pivoted relative to the catheter, the ultrasound transducer array may have a field of view distal to the distal end of the catheter.

International Classification:

A61F002/06

US Classification:

623001110, 606194000, 604103040

Abstract:

Catheter having a proximal section and a distal section. The proximal section having at least a delivery lumen and a guidewire receiving lumen, the guidewire receiving lumen having a proximal guidewire exit port at a location proximal of the distal end of the proximal section. A reinforcing tubular member located in the proximal section delivery lumen extending from substantially the proximal end of the proximal section to a point distal to the proximal guidewire exit port, wherein the reinforcing tubular member transitions from relatively rigid to relatively more flexible from a proximal point to a distal point thereon and has an outer diameter equal to about the inner diameter of the delivery lumen for at least a portion of the reinforcing tubular member that extends distal to the proximal guidewire exit port. The distal section having at least a delivery lumen and a guidewire receiving lumen.

Abstract:

An improved catheter is provided. The catheter may include a deflectable member located at a distal end of a catheter body. The deflectable member may comprise an ultrasound transducer array. The deflectable member may be interconnected to the catheter body by a live hinge. The catheter may include a lumen extending from a proximal end of the catheter body to the distal end. The lumen may be used to deliver an interventional device to a point distal to the distal end of the catheter body. The deflectable member may be selectively deflectable in a pivot-like manner through an arc of at least 90 degrees. In embodiments where the deflectable member includes an ultrasound transducer array, the ultrasound transducer array may be operable to image both when aligned with the catheter body and when pivoted relative to the catheter body.
