| 20110218503 | SYSTEMS AND METHODS FOR TRANSEPTAL CARDIAC PROCEDURES, INCLUDING ADJUSTABLE, SEPARABLE GUIDEWIRES - Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment device in accordance with a particular embodiment includes an elongated intravascular guidewire that includes a first branch and a second branch fixedly secured relative to the first branch at a first location and releasably secured relative to the first branch at a second location. At least one of the first and second branches is movable relative to the other between a first position in which the first and second branches form a closed shape, and a second position in which the first and second branches form an open shape. A controller can be operatively coupled to the first and second branches to control (e.g., in a fixed increment manner or a continuously variable manner) a distance between a portion of the first branch and a portion of the second branch while the first and second branches form the closed shape. | 09-08-2011 |
| 20110087211 | TISSUE-PENETRATING GUIDEWIRES WITH SHAPED TIPS, AND ASSOCIATED SYSTEMS AND METHODS - Tissue-penetrating guidewires with shaped tips, and associated systems and methods are disclosed. A patient treatment system in accordance with one embodiment of the disclosure includes a tissue-penetrating guidewire that in turn includes a flexible segment having a distal portion and a proximal portion. The flexible segment is elongated along an elongation axis. A penetrating member is positioned at the distal portion and includes at least one blade segment having a tapered outer peripheral surface and an adjacent generally sharp edge. The blade segment extends to a distal end of the penetrating member to form a generally blunt tip. In operation, the guidewire can be connected to an electrical current source to deliver high frequency current to the penetrating member. | 04-14-2011 |
| 20100087811 | Systems and Methods for Controlling Patient Catheters - Systems and methods for controlling patient catheters are disclosed. A system in accordance with a particular embodiment includes a catheter carrying multiple active elements, and a controller connected to the catheter. The controller can include a housing having directional indicators, and multiple control elements coupled to the multiple active elements. Individual control elements can be moveable relative to the housing to control the motion of the active elements, and the multiple control elements can be positioned so that manipulation of the multiple control elements in a first order that is clockwise or counterclockwise as identified by the directional indicators moves the multiple active elements in a first manner, and manipulation of the multiple control elements in a second order opposite the first order moves the multiple active elements in a second manner opposite the first manner. | 04-08-2010 |
| 20090131925 | Systems and Methods for Transeptal Cardiac Procedures, Including Separable Guidewires - Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment device in accordance with a particular embodiment includes an elongated first intravenous guidewire that includes a first branch and a second branch fixably secured relative to the first branch at a first location. The device can further include an elongated second intravenous guidewire that is movable relative to at least one of the first and second branches between a first position in which the first and second branches are releasably secured relative to each other by the second guidewire at a second location, and a second position in which the first and second branches are separated from each other at the second location. | 05-21-2009 |
| 20090118726 | Systems and Methods for Transeptal Cardiac Procedures, Including Tissue Sealing Members Associated Methods - Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment device in accordance with a particular embodiment includes a catheter having a proximal end, a distal end, a working portion toward the distal end, and an electrical energy path coupleable to a source of electrical energy. The device can further include a tissue penetrating member carried by the catheter and an electrode device carried by the working portion of the catheter and movable along the tissue penetrating member. The electrode device can include a collapsible stranded conductive material coupled to the electrical signal path and being changeable between a deployed position and a stowed position. The conductive material can be elongated along a deployment axis when in the stowed position, and can be contracted along the deployment axis and expanded transverse to the deployment axis when in the deployed position. | 05-07-2009 |
| 20090093803 | Systems and Methods for Transeptal Cardiac Procedures, Including Tissue Compression Devices and Methods - Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment system in accordance with a particular embodiment includes a catheter, a tissue penetration device carried by and deployable from the catheter, an energy delivery device carried by an deployable from the catheter, a backstop surface carried by the catheter, and a flexible, resilient tissue compression device. The tissue compression device can be coupled between the energy delivery device and the catheter and can be changeable between a first configuration in which the energy delivery device applies a first force to the backstop surface via intervening tissue, and a second configuration in which the energy delivery device applies no force or a second force less than the first force into the backstop surface via intervening tissue. | 04-09-2009 |
| 20090093802 | Systems and Methods for Transeptal Cardiac Procedures, Including Tissue Penetrating Members and Associted Methods - Systems and methods for transeptal cardiac procedures are disclosed. A method for treating a patient in accordance with a particular embodiment includes positioning a tissue penetrating guidewire adjacent to a cardiac septum, directing pulses of energy to the guidewire, and advancing the guidewire into and through the septum by moving the guidewire in a distal direction in a series of discrete steps. Individual steps can be of a predetermined distance measured outside the patient's body. The method can further include passing a catheter over the guidewire after the guidewire has passed through the septum. | 04-09-2009 |
| 20080312646 | Transseptal closure of a patent foramen ovale and other cardiac defects - The present invention provides for therapeutic treatment methods, devices, and systems for the partial or complete closure or occlusion of a patent foramen ovale (“PFO”). In particular, various methods, devices, and systems for joining or welding tissues, in order to therapeutically close a PFO are described. In yet another aspect of the invention, various methods, devices, and systems for the penetration of the interatrial septum enabling left atrial access are also provided. | 12-18-2008 |
