Patent number: 8444625Abstract: Some embodiments relate to a catheter system having a changeable or adjustable working length. The catheter system can comprise a proximal end, a distal end, and a first axial lumen configured to receive a guidewire formed through at least a portion of the catheter body. A first opening can be formed through a portion of the catheter body and be in communication with the first lumen. The sheath can be rotatable, axially movable, or otherwise changeable from at least a first position to a second position, wherein the sheath can substantially cover the first opening in the catheter body in the first position, and can substantially expose the first opening in the catheter body in the second position.Type: GrantFiled: May 7, 2010Date of Patent: May 21, 2013Assignee: Nexeon Medsystems, Inc.Inventors: Kent C. B. Stalker, John D. Whitfield, Mark C. Bates, Peter J. D'Aquanni, Jason Andrew Habeger

Patent number: 8442656Abstract: A cardiac lead adapted for fixation at least partially within a cardiac vessel. The lead includes, in one embodiment, an elongate lead body defining a proximal region and a distal region including a distal end region having at least one electrode and a distal tip. The distal end region is configured such that the electrode and the distal tip can be implanted in the cardiac vessel. Stiffening structures in the distal region of the lead are adapted to stiffen selected portions of the lead for fixation of the electrode within the cardiac vessel. In some embodiments, the stiffening structures include an implantable member adapted to be implanted in a lumen of the lead. In other embodiments, the stiffening structures include a sheath adapted to be deployed over the lead body. In still other embodiments, the stiffening structures are integral to the lead and/or the lead body.Type: GrantFiled: June 2, 2006Date of Patent: May 14, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Bruce A.

Patent number: 8057399Abstract: An anchor for an implantable medical device, for example, and implantable physiologic sensor, includes a proximal hub portion, an intermediate portion extending radially and distally from the hub portion, and a distal portion extending distally from the proximal portion and adapted to engage an inner surface of a target vessel for securing the implantable medical device therein. The anchor can assume a collapsed configuration for delivery through a catheter, and an expanded configuration for fixation within the vessel once deployed. The intermediate portion extends from the proximal portion at an oblique angle, allowing the anchor to be retracted and re-collapsed within the delivery catheter after initial deployment, if re-positioning or removal of the implantable medical device is necessary or desired.Type: GrantFiled: September 14, 2007Date of Patent: November 15, 2011Assignee: Cardiac Pacemakers, Inc.Inventors: John S. Greenland, Peter J. D'Aquanni, William S. Chin, Charles R. Peterson, Kevin M. Magrini, Jessie Delgado, Benjamin R. Fruland

Patent number: 8052731Abstract: A medical electrical lead adapted to be at least partially implanted in a cardiac vessel includes a fixation feature operable to change from an undeployed configuration to a deployed configuration in which the fixation feature is adapted to engage an inner surface of the cardiac vessel. A tendon is disposed within a lumen of the lead and is operatively connected to the fixation feature and adapted to cause the fixation feature to change from the undeployed configuration to the deployed configuration for acute and/or chronic fixation of the lead. In one embodiment, the fixation feature includes a deflectable region of the lead which in the deployed configuration causes a surface of the lead body to engage the inner surface of the cardiac vessel. In another embodiment, the fixation feature includes a radially expandable structure for engaging the inner surface of the vessel in the deployed configuration.Type: GrantFiled: June 2, 2006Date of Patent: November 8, 2011Assignee: Cardiac Pacemakers, Inc.Inventors: Brian D.

Patent number: 7765015Abstract: A medical electrical lead configured for use in stimulating the left side of the heart (i.e., the left ventricle). In one embodiment, the lead includes an elongate lead body including an inner surface. An inflatable member is disposed on the outer surface of the body between its proximal and distal ends, the inflatable member being adapted when inflated to impart a radial force on and frictionally engage a surface of the coronary sinus or coronary vein for fixation of the distal end of the lead therein. The lead further includes a conductive member extending from the proximal end toward the distal end, and an inner insulating layer positioned between the conductive member and the inner surface of the body. Separation between the inner insulating layer and the inner surface of the body defines an inflation lumen in fluid communication with the inflatable member.Type: GrantFiled: January 12, 2007Date of Patent: July 27, 2010Assignee: Cardiac Pacemakers, Inc.Inventors: Eric T.

Patent number: 7725197Abstract: Medical electrical leads are provided including fixation features for acute and chronic fixation of a portion of the respective leads within the cardiac venous system. The medical electrical lead includes an elongate body having proximal and distal regions. Tissue contacting portions are selectively located in the distal region to contact an inner surface of the cardiac vessel when the lead is in an implanted position. The tissue contacting portion(s) include fixation features adapted to frictionally engage the inner surface of the cardiac vessel and promote tissue in-growth for chronic fixation. In some embodiments, the fixation features are detachable from the lead such that the lead can be extracted from its implanted position after tissue in-growth occurs.Type: GrantFiled: June 15, 2006Date of Patent: May 25, 2010Assignee: Cardiac Pacemakers, Inc.Inventors: Brian D. Soltis, Bruce A. Tockman, Kent C. B. Stalker, Eric T. Johnson, Peter J. D'Aquanni
