Patent number: 9763692Abstract: Methods and systems for separating an object, such as a lead, from formed tissue are provided. Specifically, a tissue slitting device is configured to engage patient formed tissue at a slitting engagement point. While the object is subjected to a first traction force, the tissue slitting device is caused to move further into the engaged tissue and slit the tissue past the point of engagement. The slitting device causes the tissue to separate along an axial direction of the length of the formed tissue and releases at least some of the force containing the object. The methods and systems are well suited for use in cardiac pacing or defibrillator lead explant procedures.Type: GrantFiled: March 14, 2013Date of Patent: September 19, 2017Assignee: The Spectranetics CorporationInventors: Wade A. Bowe, George Woodrow Burton, Paul Joseph Dalby, Ryan Michael Sotak

Publication number: 20160183954Abstract: Snaring systems and methods involve engaging objects such as pacemaker pacing leads within a patient. Physicians can use snaring systems having loops, tags, and roller mechanisms to remove a pacing leads from a patient. For example, snaring systems can be inserted through a jugular access site, engaged with a pacemaker pacing lead, and withdrawn through the jugular access site so as to remove a portion of the pacing lead. Lead extraction techniques can be employed to further dislodge the pacing lead from the patient.Type: ApplicationFiled: December 22, 2015Publication date: June 30, 2016Inventors: Kevin D.

Patent number: 8852207Abstract: A guiding catheter system employs a compliant shaft with an inflatable balloon affixed to a distal portion of the shaft. The inflatable balloon includes channels that allow some amount of blood to flow past the balloon when inflated in a blood vessel. One or more inflation lumens is in fluid contact with the balloon and allows inflating the balloon from a proximal end of the catheter. A series of perfusion orifices may be included on the shaft proximal to the balloon.Type: GrantFiled: January 21, 2010Date of Patent: October 7, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: John A.

Patent number: 8753312Abstract: A catheter assembly employs an outer catheter with a pre-formed distal end and an open lumen. An inner catheter having an open lumen and a pre-formed distal end is movably disposed within the outer catheter. Relative rotation and extension of the inner and outer catheters provides the distal end of the catheter assembly with an adjustable range of two- and three-dimensional shapes. The inner catheter can include sections of varying stiffness, such that extension of the inner catheter within the outer catheter modifies the shape of the outer catheter's pre-formed distal end. One or both of the outer and inner catheters includes an occlusion balloon attached to the distal end thereof. The adjustable shaping of the catheter assembly's distal tip provides an improved system for locating and cannulating cardiac venous structures, particularly the coronary sinus via the right atrium.Type: GrantFiled: March 6, 2013Date of Patent: June 17, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Wade A.

Patent number: 8401673Abstract: A method of delivering a payload to a destination vessel branching from a coronary sinus of a patient's heart. The method comprises inserting a catheter assembly into a right atrium of the patient's heart. The catheter assembly comprises an outer catheter and an inner catheter movably disposed within the open lumen of the outer catheter. The inner and outer catheters are operable to be rotated and translated relative to one another such that the distal end of the outer catheter can assume a selectable plurality of shapes appropriate for accessing the coronary sinus. The method further comprises locating and cannulating the patient's coronary sinus by adjusting a relative orientation or longitudinal position of the inner catheter relative to the outer catheter, longitudinally sliding the outer catheter over the distal end of the inner catheter to deep seat the outer catheter within the patient's coronary sinus, and delivering a payload to the destination vessel through the outer catheter or the inner catheter.Type: GrantFiled: April 7, 2010Date of Patent: March 19, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Wade A.
