Patent number: 8126570Abstract: A guide catheter includes an outer guide having an open lumen and a longitudinal pre-stress line extending between a distal end and a proximal end of the outer guide. The outer guide has a longitudinal stiffness that facilitates transmission of forces and prevention of kinking during steering of the outer guide within cardiac vasculature and structures. An inner guide has an open lumen and is movably displaceable within the open lumen of the outer guide. At least a distal end of the outer guide and inner guide are dimensioned for passage into the patient's coronary sinus. A guide handle is connected to the proximal end of the outer guide and includes a longitudinal pre-stress line separable into at least two sections such that guide handle separation splits the outer guide along the longitudinal pre-stress line at the proximal end of the outer guide.Type: GrantFiled: April 13, 2010Date of Patent: February 28, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Frank E. Manning, Charles R. Peterson, Howard P. Graham

Patent number: 7493156Abstract: A guide catheter employs a retractable inner sheath movably disposed within an open lumen of an outer sheath. The inner sheath includes a pre-formed distal end and an open lumen adapted to receive a payload. The inner sheath is translatable and rotatable relative to the outer sheath. The inner sheath conforms to the outer sheath shape until it is distally extended beyond the outer sheath. The outer sheath contains a steering tendon that can be used to adjustably deflect the outer sheath. The guide catheter further includes a proximally attached guide handle. A steering handle can be pivotably connected to the guide handle. The steering handle is connected to the steering tendon and can apply a tensile force to the steering tendon for adjustably deflecting the outer sheath. A catheter according to the present invention provides an improved system for locating and cannulating cardiac venous structures, particularly the coronary sinus via the right atrium.Type: GrantFiled: January 7, 2002Date of Patent: February 17, 2009Assignee: Cardiac Pacemakers, Inc.Inventors: Frank E. Manning, Charles R. Peterson, Howard P. Graham

Patent number: 7117039Abstract: Methods of using a guide catheter employ a retractable inner guide movably disposed within an open lumen of a splittable outer guide. The outer guide includes a longitudinal pre-stress line extending from distal to proximal ends. The inner guide includes an open lumen adapted to receive a payload. The inner guide is translatable and rotatable relative to the outer guide. The guide catheter further includes a proximally attached guide handle which is separable into at least two sections. Separation of the guide handle splits the proximal end of the outer guide. Proximal outer guide retraction continues the splitting of the outer guide along the longitudinal pre-stress line.Type: GrantFiled: November 3, 2004Date of Patent: October 3, 2006Assignee: Cardiac Pacemakers, Inc.Inventors: Frank E. Manning, Charles R. Peterson, Howard P. Graham

Publication number: 20040260236Abstract: Methods involving guide catheters include providing a guide catheter that has an outer sheath having an open lumen and a pre-shaped distal end, and an inner sheath having an open lumen and a distal end provided with a pre-formed shape. A steering tendon is disposed along the outer sheath, a distal end of which is connected to the outer sheath's distal tip. A steering mechanism is connected to a proximal end of the steering tendon and includes a guide handle. The inner sheath is rotated and longitudinally translated relative to the outer sheath, whereby the distal end of the inner sheath assumes its pre-formed shape when the inner sheath's distal end extends beyond the outer sheath's distal end. A pulling force applied to the steering tendon adjustably changes a shape of the outer sheath's pre-shaped distal end. A payload may be advanced through the inner sheath's open lumen.Type: ApplicationFiled: July 14, 2004Publication date: December 23, 2004Applicant: Cardiac Pacemakers, Inc.Inventors: Frank E.
