Patent number: 9345528Abstract: A medical device including an ablation element. A thermally insulative sheath is included disposed within the ablation element. A fluid injection tube is disposed within a portion of the thermally insulative sheath. The ablation element passively transitions from a substantially linear geometric configuration to a substantially circular geometric configuration as the sheath is retracted proximally from a first position in which the sheath substantially encloses the fluid injection tube to a second position in which a portion of the fluid injection tube extends a distance away from the sheath.Type: GrantFiled: January 27, 2012Date of Patent: May 24, 2016Assignee: Medtronic CryoCath LPInventors: Timothy G. Laske, Claudia Lueckge, Réal Ste-Marie

Patent number: 9168080Abstract: A medical device including a catheter body defining a proximal portion and a distal portion. An expandable element is included defining a proximal end and a distal end, the proximal end being coupled to the distal portion of the catheter body. A tip element coupled to the distal end of the expandable element is included, the tip element including a shaft slideably receivable within a portion of the catheter body. A tensioning element coupled to the shaft and disposed within the expandable element is included, the tensioning element being engageable with the distal end of the catheter body and biasing the expandable element toward a pre-determined longitudinal position. An electrode array defining a substantially closed loop affixed to and extending from the tip element is also included.Type: GrantFiled: January 27, 2012Date of Patent: October 27, 2015Assignee: Medtronic CryoCath LPInventors: Dan Wittenberger, Claudia Lueckge, Réal Ste-Marie

Patent number: 8398632Abstract: A medical device is provided having a means for actuating a pair of opposing jaw members. The jaw members are movable relative to one another from a first position, wherein the jaw members are disposed in a spaced apart relation relative to one another, to a second position, wherein the jaw members cooperate to grasp tissue therebetween. An ablation tool is connected to at least one of the jaws members, such that the jaw members are capable of conducting ablation energy through the tissue grasped therebetween.Type: GrantFiled: March 14, 2006Date of Patent: March 19, 2013Assignee: Medtronic Cryocath LPInventors: Daniel Nahon, Sean Carroll, Dan Wittenberger, Cristian Petre, Allan Skanes, Alan H.
