Abstract

In accordance with the present invention there is provided a suturing device. The suturing device includes a length of suture that will be delivered to the site of the PFO and placed through the tissue adjacent the opening to close the PFO. As described in greater detail below, the suture is advanced through the tissue surrounding the opening by a pair of needles that penetrate the tissue adjacent to the opening. A knot is then loosely tied with the length of suture and advanced to the site of the PFO. The tails of the suture extending from the knot are then cut and removed. It is also contemplated that a pre-formed or pre-tied knot may be disposed on the device, wherein after deployment of the suture through the tissue adjacent to the PFO and removal of the device a loop of suture having a pre-tied knot will remain, wherein the pre-tied knot may then be tightened to close the PFO. Further still it is contemplated that other means may be utilized to retain the sutures. For example, it is contemplated that a suture clip or other clip like device may be utilized to retain the suture in a position such that the PFO is closed.

Claims16

Dependent claims

A method for closing a septal defect, the method comprising:

following positioning one of a proximal facing surface or a distal facing surface of a first extendable locating foot to engage but not penetrate septal tissue forming the septal defect in a first atrium communicating with one end of a tunnel of the septal defect, advancing a first needle toward the first extendable locating foot to advance a suture material portion through the septal tissue;
following positioning a facing surface of a second extendable locating foot in a second atrium communicating with another end of the tunnel of the septal defect, the first atrium being different from the second atrium, the second extendable locating foot engaging but not penetrating septal tissue forming the septal defect in the second atrium, and the facing surface facing oppositely to the one of the proximal facing surface or the distal facing surface of the first extendable locating foot engaging with the septal tissue, advancing a second needle towards the second extendable locating foot to advance other suture material portion through the septal tissue;
and
securing the suture material portion and the other suture material portion to close a septal defect,
wherein, the first needle is advanced from the second atrium to enter the first atrium to advance the suture material through the septal tissue and the second needle is advanced from the first atrium to the second atrium to advance the other suture material portion through the septal tissue.
