Abstract: A suturing device, and methods for suturing various sizes of apertures in tissues, are presented. The suturing device has a body with at least one or more adjustable arms that are coupled with catch targets. The arms are coupled with needle guides such that movements of the arms orient the needle guides to direct the needles towards the catch targets. The catch targets are coupled with sutures, such that when the needles reach the targets, they capture and pull the sutures back to the body. By changing the angles at which the arms extend from the body, the catch targets are moved closer to, or farther from, the body, and the suture device is readily configured to suture various sizes of apertures.

Abstract: Suturing devices, systems, and methods used to suture biological structures. The suturing devices can be configured to place sutures into body tissue from one side of the tissue without requiring a component on an opposite side of the tissue and without requiring insertion of components into the body tissue beyond the needles and the suture.

Abstract: A suturing device for suturing a portion of biological tissue includes a needle attached to a suture, a needle holder that releasably holds the needle, and a needle driver adapted to be advanced and retracted substantially parallel to a longitudinal axis of the suturing device. A distal needle holder adapted to releasably hold the needle is positioned in a distal position relative to the portion of biological tissue and a distal end of the needle driver is positioned in a proximal position relative to the portion of biological tissue. The needle is positioned in either the proximal position or the distal position. The needle driver is moved longitudinally in a first direction along a path substantially parallel to the longitudinal axis such that the needle and suture pass through the portion of biological tissue, thereby forming a suture incision through which the suture passes. By repeating the above-described processes, a series of stitches is thereby formed.

Abstract: A device for suturing an anatomic valve can comprise an elongate body, a suture catch mechanism and a suture clasp arm. The suture catch mechanism can be operatively coupled to the elongate body for movement between a retracted position and an advanced position. The suture clasp arm can be attached to the elongate body for movement between a retracted position and an extended position. The suture clasp arm can comprise a suture clasp configured to releasably retain a suture portion. In some embodiments, the suture clasp is positioned on the suture clasp arm such that the suture catch mechanism retrieves the suture portion from the suture clasp arm while the arm is at least partially retracted. In some embodiments, the suture clasp arm can be closed about a tissue portion without damaging the tissue portion.

Abstract: Disclosed herein are embodiments of devices and methods for forming a seal covering an incision in tissue. In some embodiments, a deformable member can be loaded into a catheter and inserted into the tissue incision. The deformable member can unfold into a cup-shape which can form a seal around the incision during a procedure. Once the procedure is finished, the deformable member can be drawn back into the tube.

Abstract: Methods and apparatuses are disclosed for closing a patent foramen ovale. Some of the disclosed apparatuses include an elongate body having a proximal end and a distal end, with first and second suture clasp arms adapted to hold end portions of a suture when in an extended position. A first suture catch mechanism is slidably housed in the elongate body and moves in a proximal-to-distal direction to engage the suture end held by the first suture clasp arm, and a second suture catch mechanism is slidably housed in the elongate body and moves in a distal-to-proximal direction to suture end held by the second suture clasp arm. The first suture clasp arm can be positioned around the septum primum to deliver a suture thereto, and the second suture clasp arm can be positioned around the septum secundum to deliver a suture thereto.

Abstract: 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.

Abstract: A suturing device allows a physician to remotely seal an incision in a blood vessel or other biological tissue. The device comprises an elongated tubular body having a distal portion which is adapted to be inserted percutaneously through the incision and into the blood vessel. The distal portion has first and second retractable arms which extend from the distal portion of the body and releasably hold a suture within the blood vessel. First and second retractable needles, each of which is configured to catch the suture from a respective arm, are provided along the body proximal to the retractable arms. The arms and the needles are remotely movable by the physician using a handle or other control mechanism provided at a distal portion of the device. In operation, the arms are initially deployed within the blood vessel to hold the ends of the suture beyond the circumference of the tubular body.

Abstract: A knot placement device allows a physician to apply a knot for securing two or more suture ends extending from an incision in a vessel or organ of a patient relative to each other in order to seal an opening in the vessel or organ. The knot placement device has a handle and an elongate shaft and a push rod slidably inserted in said shaft. A knot is disposed in the distal end of the shaft. An actuator on the handle may be depressed to distally advance said push rod relative to said shaft and thereby distally advance said knot. The knot may include a knot body having an inner cavity and a plug sized to fit securely within the inner cavity. In use, the plug may be inserted into the inner cavity of the knot body to fixedly hold two or more suture ends between the knot body and the plug.

Abstract: Methods and apparatus are provided for closing incisions within biological tissue. In one embodiment, a device and method are provided for suturing biological tissue, such as, for example, an organ or blood vessel. The suturing apparatus is particularly well suited for suturing an incision made in an artery, such as the femoral artery, following a catheterization procedure. The device eliminates the need to apply pressure to a patient's thigh for an extended period of time, and eliminates many of the complications and costs associated with the creation of a thrombus patch. In addition, the device comprises an improved handle portion which enables the physician to quickly and easily apply suture. The handle portion is very reliable and easy to manipulate. The suturing may be used in combination with existing catheter sheath introducers.
