    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: A suturing instrument using a curved needle is presented. The suturing instrument includes an elongated body, which has a lumen at its distal end. The suturing device also includes a curved needle which has a hook at its distal end to capture a suture from a suture staging area coupled with the suture. The rotational movement of the curved needle can be operated by a linear movement of a controlling element via a compound pivots that are configured to move the needles out from the lumen, couple the needle to the suture, and pull the suture away back toward the lumen.

    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: A catheter assembly comprises a transparent hub and a transparent catheter coupled to the transparent hub at a proximal end. The present inventive concept further contemplates that the transparent hub can further comprise components, including but not limited to, a valve, a valve housing, a catheter securing mechanism, a hub body. The present inventive concept further contemplates a catheter assembly comprising one or more transparent components, such that the catheter assembly reveals the contents therein to a user.

    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: A suture device with a holding block, and methods of controlling relative positions of ends of multiple suture needles in the suture device, are presented. The suture device has two or more suture needles, and a guide wire, all of which are coupled to the holding block. Suture needles are affixed at the holding block at two distinct contact regions and the guide wire is disposed at the holding block in a slidable relationship. By affixing two needles at the holding block, the relative positions of ends of suture needles can be maintained in the suture device, so that two needles can capture sutures simultaneously, even when two needles are curved in opposite directions.
