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.

Device and method for suturing intracardiac defects

In accordance with the present disclosure there is provided exemplary embodiments of an introducer sheath, wherein the introducer sheath may be formed of multiple components at least one of which may be integrally formed or resiliently assembled to form a single introducer sheath. One embodiment of the introducer sheath includes a hub and a flexible valve. The flexible valve member may be non-planar in a relaxed state.

Modular introducer and exchange sheath

Devices and methods for securing a pair of suture lengths together or for using a single strand of suture to secure tissue(s) together at an operative site in a patient without necessarily tying a knot. The suture lock device includes a suturing securing device having an outer body member having a lumen extending therethrough. The lumen defines a suture path through the outer body. An inner wedge member is axially insertable into the outer body member to secure a portion of a suture between the wedge and the interior surface of the lock member. An outer tube has a proximal end and a distal end. The outer tube carries the outer body member at the distal end of the outer tube. The outer tube carries the wedge proximal to the outer body member.

Suture locking device and methods

In accordance with the present invention there is provided exemplary embodiments of an introducer sheath in accordance with the present invention, wherein the introducer sheath of the present invention is formed of multiple components which are resiliently assembled to form a single introducer sheath. One embodiment of the introducer sheath includes a hub, a retaining member and an elongated tubular member. The hub has a lumen that has a groove. The elongated tubular member has a proximal end that includes a flared portion. The distal end of the retaining member is configured to be received in the groove formed in the lumen of the hub. The distal end of the retaining member contacts the flared portion of the tubular member when distal end of the retaining member is disposed in the groove such that the tubular member is retained within the lumen of the hub in a sealed engagement.

A method for suturing a patent foramen ovale (PFO) includes providing a suturing device, advancing the suturing device through the inferior vena cava, right atrium, and PFO such that a first foot of the device is positioned in the left atrium, deploying the first foot to a deployed position, orienting the suturing device such that a distal portion of tissue of the PFO is received in a pre-formed curve portion of a foot housing of the device, advancing the first needle through tissue and further into a first needle receptacle disposed on the first foot, and advancing at least one end of the length of suture through the tissue to suture the PFO.

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 patent foramen ovale (PFO) and placed through the tissue adjacent the opening to close the PFO. The suture is advanced through the tissue surrounding the opening by a pair of needles that penetrate the tissue adjacent to the opening. The suture can be secured to the tissue through use of a knot, a suture clip or other clip like device to retain the suture in a position such that the PFO is closed.
