SUTURE DELIVERY DEVICE
A suture-based vessel closure device can perform the dilation of an arteriotomy puncture and does not require previous dilation of the arteriotomy puncture by a separate device or by a procedural sheath dilator. The suture-based vessel closure device can place one or more sutures across the vessel access site such that, when the suture ends are tied off after sheath removal, the stitch or stitches provide hemostasis to the access site.
HERNIA REPAIR DEVICE
A hernia repair device including a main body, a plurality of suture needle ports, a plurality of suture needles and a central shaft. The central shaft includes a retractable distal flange disposed at a distal end portion of the central shaft and defines a central channel extending through the main body. The suture needle ports are adjustable between a first configuration in which the suture needle ports are housed entirely within the main body and a second configuration in which the suture needle ports partially extend from the distal end portion of the main body. The suture needles are adjustable between a first configuration in which the suture needles are housed entirely within the suture needle ports and a plurality of second configurations in which the suture needles partially extend from distal end portions of the suture needle ports. A hernia repair mesh is attached to the plurality of suture needles.

SYSTEMS AND METHODS FOR SUTURING TISSUE
In accordance with an aspect of the present disclosure, an apparatus for suturing tissue is provided that includes a body having a proximate end and a distal end. A suturing head is coupled to the distal end of the body, including a first set of curved needles, a second set of curved needles, and a plurality of sutures. A first end of a suture is coupled to one of the curved needles of the first set. A second end of the suture is coupled to one of the curved needles of the second set. The curved needles of the first set are oppositely oriented to the curved needles of the second set. The suturing head can be positioned between two substantially parallel sections of tissue. An actuator is coupled to the body to deploy the first and second sets of curved needles.

The system further includes a delivery device including a catheter having a proximal end portion and a distal end portion, the implantable fixation device releasably coupled to the distal end portion of the catheter, the catheter defining at least one lumen extending between the proximal end portion and the distal end portion. The delivery device further includes a first proximal element line extending through the at least one lumen, the first proximal element line coupled to the first proximal element and actuatable to move the first proximal element between the first position and second position, and a second proximal element line extending through the at least one lumen, the second proximal element line coupled to the second proximal element and actuatable to move the second proximal element between the first position and second position. The first proximal element line and the second proximal element line are independently actuatable.
Trocar and wound closure device
A trocar adapted for insertion through a fascia layer of an abdominal wall, comprising a proximal end configured for handling by a user; a distal end configured for insertion into tissue; and a shaft extending in between the proximal end and distal end, wherein the shaft comprises a narrow portion proximal to the distal end, the narrow portion defining at least one recess shaped and sized to receive fascia tissue, the recess ending, at a distal end, with a generally proximally facing surface of the shaft configured directly below the narrow portion, the proximally facing surface and the narrow portion shaped and sized to stabilize the trocar in the abdominal wall by the fascia. In some embodiments, a trocar and external cannula assembly are provided. In some embodiments, the trocar and/or trocar and external cannula assembly are configured for deployment of one or more anchors and/or sutures in the tissue.

Methods and devices for capturing and fixing leaflets in valve repair
The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.
Suturing devices and methods for suturing an anatomic valve
Suturing apparatuses configured to suture biological tissue, such as an anatomical valve. The suturing apparatuses can comprise an elongate member having a proximal end, a distal end, one or more arms, and one or more needles. A protective member may be used to inhibit contact between a distal end of a needle and surrounding tissue. Methods for suturing bodily tissue such as an anatomical valve may be performed with the suturing apparatuses. The suturing apparatuses may be used to suture adjacent valve leaflets or the base of a valve in order to treat or repair the valve.
