Patent number: 10675447Abstract: One embodiment is directed to a method for creating translumenal vascular access, comprising utilizing a dilator adaptor to assist with forming a substantially atraumatic geometric outer junction between a dilator member/introducer member assembly and a guidewire which may be somewhat undersized relative to a lumen formed through the dilator member, thereby creating a geometric fit gap which may be suboptimal from a tissue interfacing perspective. The dilator adaptor may be interposed between the guidewire and dilator member to assist in remedying this fit mismatch, and in generally providing a preferred outer instrument interface for insertion through a small defect in a vessel to gain access to a lumen defined through the vessel.Type: GrantFiled: April 30, 2018Date of Patent: June 9, 2020Assignee: ARSTASIS, INC.Inventors: Brian Andrew Ellingwood, D.

Patent number: 8979882Abstract: Described here are methods and devices for forming tracts in tissue. Some of the devices feature 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 feature 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 features 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.Type: GrantFiled: July 21, 2009Date of Patent: March 17, 2015Assignee: Arstasis, Inc.Inventors: Michael Drews, D.

Publication number: 20120053609Abstract: Described here are 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 comprise advancing a tissue-locating member adjacent to a tissue wall, deforming at least a portion of the tissue wall with the tissue-locating member, and advancing a tissue-piercing member through the deformed tissue to form the tract, where the tract provides access for one or more tools. Also described here are methods of forming tracts through rotated or tented tissue. Any of the methods described here may also be used with tissue having at least one irregular surface.Type: ApplicationFiled: November 4, 2011Publication date: March 1, 2012Applicant: ARSTASIS, INC.Inventors: D.
