20120296347, Nov 22, 2012

Filed:

May 19, 2011

Appl. No.:

13/111416

Inventors:

Wouter E. Roorda - Palo Alto CA, US
Laveille Kao Voss - Belmont CA, US
David J. Milazzo - Santa Clara CA, US
Aaron M. Fortson - Fremont CA, US

Assignee:

ABBOTT CARDIOVASCULAR SYSTEMS, INC. - Santa Clara CA

International Classification:

A61B 17/04

US Classification:

606145

Abstract:

A suture applying device includes a shaft which carries a pair of needles near its distal end. The needles are joined by a length of suture, and the shaft is used to both introduce the needles into a lumen of a body structure and to draw the needles back through tissue on either side of the puncture site. After the needles have passed through the tissue, they are captured by a needle receiver and drawn outward through the tract, leaving a loop of suture behind to close the puncture site near the body lumen. The suture can then be tied or otherwise secured to close the puncture site.

International Classification:

A61B 17/04

US Classification:

606144

Abstract:

An apparatus for suturing body lumens is provided. The apparatus includes a flexible elongated member that has a proximal end, a distal end, a central passage and multiple needle lumens extending from the proximal end toward the distal end. The flexible elongated member further includes an elongated subsection spanning from the end of the needle lumens in the elongated member to a barrel portion that includes corresponding needle lumens on the proximal end of the elongated member. The elongated subsection provides sufficient space between the needles and the barrel portion to allow transapical insertion of the elongated member into a body lumen. The apparatus further includes needles disposed within and advanceable from the needle lumens. The apparatus also includes a handle disposed at the proximal end of the elongated member. The handle is operable to retract the needles through the needle lumens toward the handle at the proximal end.

International Classification:

A61B 17/03

US Classification:

606213

Abstract:

A closure device for closing an opening in tissue is provided. The closure device includes an elongate member through which needles may be deployed. The closure device also includes a foot portion having one or more feet slidably mounted relative thereto. The feet are movable between a deployed position and a delivery position. The feet include cuffs removably mounted therein, with sutures connected between the cuffs. When the feet are in the deployed position and the needles are advanced, the needles securely engage the cuffs and draw the cuffs and suture through the lumen wall so that the opening in the lumen wall can be closed with the sutures.

International Classification:

A61B 17/04
A61B 17/06

Abstract:

A device for closing an opening in a body lumen, the device having a first elongate member with a first lumen, a second elongate member distal the first elongate member, and a needle assembly slidably cooperating with the first elongate member to position a plurality of sutures within the lumen of the first elongate member. The needle assembly includes a needle base and a plurality of needle portions extending from the needle base. Slidable movement of the needle assembly in relation to the first elongate member locates the plurality of sutures selectively mounted to the needle assembly within the first lumen.
