Abstract: A minimally invasive device and method for suturing papillary muscles includes drawing a suture through a first papillary muscle using a needle, drawing the suture through a second papillary muscle, and tightening the suture to move at least one of the first papillary muscle and the second papillary muscle towards the other of the first papillary muscle and the second papillary muscle.

Abstract: Suturing apparatuses can be configured to suture biological tissue, such as an anatomical valve. The suturing apparatuses can include a suturing device having an elongate shaft having a proximal end and a distal end, one or more tissue grasping arms, and a handle with actuators. The suturing device can further include at least two needles. One of the tissue grasping arms can have at least two suture mounts each loaded with a suture portion. The suture portions on the suture mounts can form a single suture strand. Methods for suturing bodily tissue may be performed with the suturing apparatuses. The tissue grasping arms can grasp tissue therebetween and at least two needles can be deployed toward the suture mounts, engage the suture portions, and be retracted through the tissue. A knot can be tied on the ends of the suture strand retrieved by the needles.

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: Apparatuses and methods for closing a transapical opening (9) in a wall of the heart include utilizing a suturing device (100) that is advanced through the transapical opening (9), extending suture arms (110) from a retracted position to an extended position within a ventricle of the heart, extending needles (120) from a retracted position to an extended position through the wall of the heart to engage a plurality of suture portions (52) held by the suture arms (110), retracting the needles through the wall of the heart to draw the suture portions through the wall of the heart, retracting the suture arms, withdrawing the suturing device from the transapical opening, and closing the transapical opening with the suture portions (52). The needles (120) can be deployed from within the transapical opening (9) at an angle to a longitudinal axis of the suturing device or through the exterior wall of the heart parallel to the longitudinal axis of the suturing device.

Abstract: Suturing devices and systems used to close openings into a biological structure. The suturing device can comprise an elongate member having a proximal end, a distal end, one or more arms, and one or more needles. One or more sheaths may be used with the device to maintain or substantially maintain haemostasis while the device is used and while a procedure is performed in the biological structure.
