13/587781
Inventors:
Farhad Khosravi - Los Altos Hills CA, US
Suresh S. Pai - Mountain View CA, US
Celso J. Bagaoisan - Union City CA, US

Apparatus And Methods For Sealing A Vascular Puncture

US Patent:
8617204, Dec 31, 2013
Filed:
Sep 12, 2007
Appl. No.:
11/854534
Inventors:
Farhad Khosravi - Los Altos Hills CA, US
Suresh S. Pai - Mountian View CA, US
Celso J. Bagaoisan - Union City CA, US
Scott R. Sershen - Belmont CA, US
Marlon Moreno - San Jose CA, US
Juan Domingo - Union City CA, US
Assignee:
Accessclosure, Inc. - Mountain View CA
International Classification:
A61B 17/08
US Classification:
606213
Abstract:
An apparatus for sealing a puncture through tissue to a vessel includes an elongate occlusion member including an expandable member, a cartridge carried on the occlusion member, and a sealant carried within the cartridge. The cartridge includes an outer member and a pusher member within the outer member. The sealant is disposed within the outer member adjacent the expandable member distal to the pusher member. During use, the occlusion member is introduced into a puncture until the expandable member and the sealant extend from the puncture into the vessel. The expandable member is expanded, and withdrawn until the expanded expandable member contacts the vessel wall, thereby withdrawing the sealant back into the puncture. The outer member is withdrawn to expose the sealant within the puncture, while the pusher member prevents removal of the sealant, and then the cartridge, occlusion member, and pusher member are successively removed.

Apparatus And Methods For Delivering Sealing Materials During A Percutaneous Procedure To Facilitate Hemostasis

View page
US Patent:
20050149117, Jul 7, 2005
Filed:
Dec 24, 2003
Appl. No.:
10/745946
Inventors:
Farhad Khosravi - San Mateo CA, US
Celso Bagaoisan - Union City CA, US
Suresh Pai - Mountain View CA, US
Scott Sershen - Belmont CA, US
International Classification:
A61B017/08
US Classification:
606215000
Abstract:
Apparatus and methods are provided for sealing a puncture extending through tissue to a blood vessel. A delivery sheath is introduced-into the puncture, and a sealing compound, e.g., precursor polymers that mix to create a hydrogel, is introduced through the delivery sheath into the puncture. The delivery sheath is then removed, an introducer sheath is advanced through the puncture into the vessel, and instruments are introduced through the introducer sheath into the vessel to perform a medical procedure. After completing the procedure, the introducer sheath is withdrawn. The sealing compound may expand into the puncture and/or tissue recoil of the surrounding tissue may cause the sealing compound to at least partially occlude the puncture to facilitate sealing and/or hemostasis.

US Patent:
20070060950, Mar 15, 2007
Filed:
Oct 27, 2004
Appl. No.:
10/975205
Inventors:
Farhad Khosravi - Los Altos Hills CA, US
Suresh Pai - Mountain View CA, US
Celso Bagaoisan - Union City CA, US
Scott Sershen - Belmont CA, US
International Classification:
A61B 17/08
US Classification:
606213000
Abstract:
An apparatus for sealing a puncture extending through tissue to a blood vessel includes a guidewire including an expandable tamp, a retaining sheath for covering the tamp, and a delivery sheath including a primary lumen for receiving the guidewire therethrough and a secondary lumen for delivering sealing compound into the puncture. The guidewire is advanced into the puncture with the tamp in a contracted condition, the tamp is expanded within the vessel after retracting the retaining sheath, and the guidewire is retracted to seal the puncture from the vessel. The delivery sheath is advanced over the guidewire, and sealing compound is introduced into the puncture through the delivery sheath. After introducing the sealing compound, the delivery sheath is removed, and an introducer sheath is advanced over the guidewire to provide access to perform a medical procedure via the vessel after removing the guidewire.

Superabsorbent, Freeze Dried Hydrogels For Medical Applications

View page
US Patent:
20070231366, Oct 4, 2007
Filed:
Aug 18, 2006
Appl. No.:
11/465791
Inventors:
Amarpreet S. SAWHNEY - Lexington MA, US
Steven L. Bennett - Grafton MA, US
Suresh S. Pai - Mountain View CA, US
Scott R. Sershen - Belmont CA, US
Fred H. Co - Santa Clara CA, US
International Classification:
A61K 36/17
A61K 38/17
US Classification:
424426, 514 2
Abstract:
Methods are provided for making freeze dried hydrogel and structures therefrom that may be introduced into a patient's body for medical applications. Precursor components are combined to initiate crosslinking. The combined precursor components are placed in a chilled tray, and allowed to crosslink to a desired level of complete crosslinking before and/or after being placed onto the tray. The partially crosslinked hydrogel is frozen and freeze dried. After freeze drying, the hydrogel is conditioned to substantially complete crosslinking, and formed into one or more structures, e.g., plugs, hemostatic, or other medical devices. For example, the hydrogel may be cut, machined, rolled, folded, compressed, and/or cored into that may be loaded into delivery devices that may be introduced into a body to implant or otherwise deliver the structures into the body, e.g., to seal a puncture or other passage through tissue.

US Patent:
20100274280, Oct 28, 2010
Filed:
Apr 29, 2010
Appl. No.:
12/770573
Inventors:
Amarpreet S. Sawhney - Lexington MA, US
Farhad Khosravi - Los Altos Hills CA, US
Suresh S. Pai - Mountain View CA, US
Scott R. Sershen - Redwood City CA, US
Assignee:
Incept, LLC - Mountain View CA
International Classification:
A61B 17/03
US Classification:
606213
Abstract:
Apparatus and methods for sealing a puncture through tissue or otherwise treating a body lumen of a patient. The carrier includes at least one, but not all, of the adherent layer components required to form a tacky or sticky adherent layer on the carrier. The remaining adherent layer precursor(s) are delivered to the carrier in situ to form a sticky and/or tacky adherent layer on the carrier that enhances the attachment and retention of the carrier to tissue surrounding a target treatment location in which the carrier is delivered. The carrier may include hydrogel and/or other porous material, e.g., for releasing one or more agents carried by the carrier at the treatment location.

US Patent:
20120209323, Aug 16, 2012
Filed:
Jan 19, 2012
Appl. No.:
13/354278
Inventors:
Andy H. Uchida - Los Altos CA, US
Anthony P. Spizuoco - San Francisco CA, US
Kevin To - San Jose CA, US
Florencia Lim - Union City CA, US
Scott R. Sershen - Redwood City CA, US
Assignee:
AccessClosure, Inc. - Mountain View CA
International Classification:
A61B 17/08
B32B 9/00
A61B 17/10
US Classification:
606214, 156 83
Abstract:
A sealant is provided for sealing a puncture through tissue that includes an elongate first section including a proximal end, a distal end, and a cross-section sized for delivery into a puncture through tissue, and a second section fused to and extending from the distal end of the first section. The first section may be formed from a freeze-dried hydrogel that expands when exposed to physiological fluid within a puncture. The second section may be formed from a solid mass of non-freeze-dried, non-crosslinked hydrogel precursors, the precursors remaining in an unreactive state until exposed to an aqueous physiological, whereupon the precursors undergo in-situ crosslinking with one another to provide an adhesive layer bonded to the first section. Apparatus and methods for delivering the sealant into a puncture through tissue are also provided.
