摘要： In at least one embodiment, a medical device can comprise an elongate outer sheath that extends along a sheath longitudinal axis and defines a central lumen extending therethrough, the elongate outer sheath can comprise a proximal sheath portion and a distal sheath portion. A first guidewire can comprise a first guidewire end and a second guidewire end, the first guidewire can extend from the first and second guidewire ends through the central lumen and can form a distal looped portion. An occlusion device can be disposed at a distal end of an elongate flexible shaft. The elongate flexible shaft can extend from the proximal sheath portion through the central lumen. The occlusion device can include a guide lumen through which the first guide wire passes.

摘要： A method of positioning an occlusion clip proximate a left atrial appendage may include creating an access port that exposes the left atrial appendage; delivering a suction grasper via the access port, the suction grasper including opposing jaws each having a suction port; delivering an occlusion clip via the access port; grasping the left atrial appendage via the suction grasper by applying suction to an exterior of the left atrial appendage so that a portion of the left atrial appendage interposes the opposing jaws while suction is applied via the suction ports; repositioning the suction grasper to tension the left atrial appendage; delivering an occlusion clip via the access port; clamping a base of the left atrial appendage using the occlusion clip while the suction grasper applies tension to the left atrial appendage; and/or egressing the suction grasper via the access port.

摘要： Medical devices are disclosed. An example surgical spacemaking device may include an elongate element configured for insertion into a patient's body and including a distal end portion and an internal lumen, an inner element disposed generally coaxially within the internal lumen of the elongate element, an expandable element disposed generally circumferentially about a distal end portion of the inner element, and an actuator operable to reposition the expandable element between a contracted configuration and an expanded configuration. In the contracted configuration, the expandable element may have a relatively small diameter and, in the expanded configuration, the expandable element may have a relatively large diameter.

摘要： Embodiments of the present invention encompass systems and methods for delivering ligatures to anatomical features of a patient. Exemplary ligature delivery systems for use in delivering a ligature to a left atrial appendage ligature include an elongate support mechanism having a proximal portion and a distal portion, a flexible hoop assembly, and a cinchable constriction member. The flexible hoop assembly can be coupled with the distal portion of the elongate support mechanism, and can include a support body coupled with a support frame. The support frame can be biased to hold the support body in a trailing configuration, whereby a free portion of the support body is disposed proximal to the distal portion of the elongate support mechanism. The support frame of the flexible hoop assembly can be coupled with the distal portion of the elongate support mechanism. The support body can be configured to support the cinchable constriction member and a loop of the left atrial appendage ligature.

摘要： An example system for applying an occlusion clip to an anatomical structure may include a visualization tool configured to allow visualization of an anatomical structure using a scope; a clip applier configured to apply an occlusion clip on the anatomical structure; an introducer connectable to the clip applier and configured to aid in positioning the clip applier; and a positioner configured to apply at least one of a linear force and a torsional force to at least one of the clip applier and the clip.

摘要： Devices and methods for clamping tissue and/or moving two tissue structures together by moving two plates or arm together. The pressure or force applied to the tissue may be used to bring the tissue together, to seal an opening or to cut through and remove a portion of the tissue. In one procedure disclosed, a clip applier may be used to apply one or more clips to the left atrial appendage of the heart to prevent clots from the left atrial appendage from embolizing and causing harm to the patient, such as a stroke.

摘要： Embodiments of the present invention encompass systems and methods to prevent complications from atrial fibrillation by preventing or reducing the likelihood of blood flow out of the left atrial appendage, to eliminate a possible source of aberrant electrical circuits, or both. Accordingly, techniques are provided for delivering ligature loops or closure means to the left atrial appendage, and to other anatomical structures of a patient which may be desirable in other surgical procedures.
