20160106457 | ACCESS CLOSURE CONFIGURATION - One embodiment is directed to a device for forming a tract, comprising an anchor assembly wherein at least a distal tip of the flexible distal portion is configured to be placed within a lumen of a blood vessel through a first passage created across the wall with a sharpened member at a first angle relative to a lumen longitudinal axis defined by the lumen of the blood vessel in the region adjacent the first passage; and wherein upon applying a force to the anchor assembly to position an adjacent portion of the blood vessel wall into a desired contact configuration relative to the anchor assembly, the needle is operatively coupled to the anchor assembly such that it may be advanced across the wall of the blood vessel and into contact with a saddle-shaped needle receiving structure, thereby creating an expandable tract between overlapping tissue portions of the vessel wall. | 04-21-2016 |
20160100829 | ACCESS CLOSURE CONFIGURATION - A method may comprise creating a first passage across a wall with a sharpened member at a first angle relative to a lumen; advancing an anchor assembly through the first passage such that a distal portion of the anchor assembly is placed within the blood vessel; applying a force to the anchor assembly to position an adjacent portion of the blood vessel wall into a desired contact configuration relative to the anchor assembly; and while maintaining the desired contact configuration, advancing a needle through a portion of the anchor assembly and through a portion of the wall of the blood vessel to form an expandable tract between overlapping tissue portions of the vessel wall, wherein a portion of the anchor assembly comprises a saddle-shaped needle receiving structure configured to receive and support the needle after it has been advanced across the portion of the wall to create the expandable tract. | 04-14-2016 |
20160095621 | ACCESS AND CLOSURE DEVICE AND METHOD - Devices and methods for accessing and closing vascular sites are disclosed. Self-sealing closure devices and methods are disclosed. A device that can make a steep and controlled access path into a vascular lumen is disclosed. Methods for using the device are also disclosed. | 04-07-2016 |
20160066948 | VASCULAR ACCESS CONFIGURATION - One embodiment is directed to a system for creating translumenal vascular access, comprising a dilator adaptor member having proximal and distal ends and defining a dilator adaptor lumen therethrough, wherein the dilator adaptor lumen is defined by an inner diameter profile sized to accommodate insertion of one or more portions of a guidewire, and wherein the dilator adaptor is further defined by an outer diameter profile sized to accommodate at least partial insertion of the proximal end of the dilator adaptor into a dilator member lumen formed through a dilator member, the dilator member being coupleable to an introducer catheter member through an introducer member lumen formed through the introducer member. | 03-10-2016 |
20140039546 | ACCESS CLOSURE CONFIGURATION - A method may comprise creating a first passage across a wall with a sharpened member at a first angle relative to a lumen; advancing an anchor assembly through the first passage such that a distal portion of the anchor assembly is placed within the blood vessel; applying a force to the anchor assembly to position an adjacent portion of the blood vessel wall into a desired contact configuration relative to the anchor assembly; and while maintaining the desired contact configuration, advancing a needle through a portion of the anchor assembly and through a portion of the wall of the blood vessel to form an expandable tract between overlapping tissue portions of the vessel wall, wherein a portion of the anchor assembly comprises a saddle-shaped needle receiving structure configured to receive and support the needle after it has been advanced across the portion of the wall to create the expandable tract. | 02-06-2014 |
20140039545 | ACCESS CLOSURE CONFIGURATION - One embodiment is directed to a device for forming a tract, comprising an anchor assembly wherein at least a distal tip of the flexible distal portion is configured to be placed within a lumen of a blood vessel through a first passage created across the wall with a sharpened member at a first angle relative to a lumen longitudinal axis defined by the lumen of the blood vessel in the region adjacent the first passage; and wherein upon applying a force to the anchor assembly to position an adjacent portion of the blood vessel wall into a desired contact configuration relative to the anchor assembly, the needle is operatively coupled to the anchor assembly such that it may be advanced across the wall of the blood vessel and into contact with a saddle-shaped needle receiving structure, thereby creating an expandable tract between overlapping tissue portions of the vessel wall. | 02-06-2014 |
20120089166 | Access and Closure Device and Method - Devices and methods for accessing and closing vascular sites are disclosed. Self-sealing closure devices and methods are disclosed. A device that can make a steep and controlled access path into a vascular lumen is disclosed. Methods for using the device are also disclosed. | 04-12-2012 |
20110230906 | DEVICES, METHODS AND KITS FOR FORMING TRACTS IN TISSUE - Described here are methods, devices and kits for locating tissue and/or forming one or more tracts in tissue. In some variations, tissue may be located (e.g., using one or more optical sensors, ultrasound sensors, thermal sensors, or the like) and one or more tracts may be formed through the tissue after it has been located. In certain variations, the same device may be used both to locate tissue and to form one or more tracts in the tissue. In some variations, a tissue-piercing member for forming one or more tracts in tissue may comprise a first elongated portion and a second elongated portion, and an angle therebetween. | 09-22-2011 |
20100016810 | DEVICES AND METHODS FOR FORMING TRACTS IN TISSUE - Described here are devices and methods for forming one or more tracts in tissue. The tracts may be formed in any suitable or desirable tissue, and may seal relatively quickly without the need for a supplemental closure device. In some variations, the methods may comprise clamping at least a portion of a tissue and advancing a tissue-piercing member through the clamped tissue to form a tract. The tract may, for example, provide access for one or more tools. | 01-21-2010 |
20100016786 | DEVICES, METHODS, AND KITS FOR FORMING TRACTS IN TISSUE - Described here are methods and devices for forming tracts in tissue. Some of the devices comprise an elongate member, a suction member coupled to a distal portion of the elongate member, and a tissue-piercing member slidably housed within the elongate member for forming a tract in tissue. Other devices comprise more than one suction member. Methods for forming tracts in tissue are also described here. In some methods, a device is advanced adjacent tissue, where the device comprises one or more suction members and a tissue-piercing member. Suction is applied so that the tissue is drawn against the one or more suction members, and a tissue-piercing member is advanced in a first direction through the drawn tissue to form a tract in or through the tissue. Kits incorporating one or more of the devices described here, in conjunction with one or more tools or the like, are also described here. | 01-21-2010 |
20090318889 | ACCESS AND CLOSURE DEVICE AND METHOD - Devices and methods for accessing and closing vascular sites are disclosed. Self-sealing closure devices and methods are disclosed. A device that can make both steeply sloping and flat access paths into a vascular lumen is disclosed. The device can also form arteriotomies with sections cleaved between a vessel's intima and adventitia. Methods for using the device are also disclosed. | 12-24-2009 |
