| 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 |
