Abstract
A method for closing a puncture in a vessel wall of a blood vessel that includes advancing a guide member into proximity with a puncture in a vessel wall, positioning a distal end of an angle adjustment member distal to openings of the guide member, deploying the needle guides from the guide member through the openings, advancing the deflected needle guides and the suture securing devices through the vessel wall, retracting the needle guides to release the suture securing devices distally of the vessel wall, and establishing tension in the sutures to move the suture securing devices toward each other to thereby close the puncture.
Core Innovation
The invention provides methods for closing a puncture in a vessel wall of a blood vessel using a guide member having openings near a distal end and a plurality of needle guides disposed within the guide member. Each needle guide comprises a suture attached to a suture securing device, and a needle guide angle adjuster is slidably coupled to the guide member and positioned distal to the openings to deflect the needle guides away from a longitudinal axis of the guide member during penetration through the vessel wall.
An anchor is advanced through the guide member to a deployment location within the blood vessel and is expanded to laterally extend beyond a deployment location of at least one suture securing device. The method further includes deploying the needle guides distally and radially away from the guide member through the openings, advancing the deflected needle guides and the suture securing devices through the vessel wall to the deployment location, and retracting the needle guides to release the suture securing devices distally of the vessel wall.
After release, the method moves the suture securing devices toward the longitudinal axis of the guide member to close the puncture by establishing tension in the sutures to move the suture securing devices toward each other. In additional embodiments, a plug is positioned against the vessel wall, and the securing device is moved toward the longitudinal axis of the guide member to close the puncture, including an embodiment where a securing device comprises an elongated body with an inner cavity, a first opening, a cutout with a periphery, a plurality of tissue-engaging elements, and a suture attached to the elongated body.
Claims Coverage
The document includes three independent claims. Across these independent claims, the coverage centers on a needle guide deployment and angle deflection mechanism, suture securing devices advanced through a vessel wall, anchoring with laterally extending expansion, and closure by moving securing devices toward a longitudinal axis of the guide member.
Angle-adjusted needle guide deployment for vessel-wall penetration
Deploying needle guides distally and radially away from the guide member through openings, deflecting the needle guides with a needle guide angle adjuster slidably coupled to the guide member, and advancing the deflected needle guides and suture securing devices through the vessel wall to a deployment location.
Anchor expansion laterally beyond deployment location
Advancing an anchor through the guide member and expanding the anchor to laterally extend beyond a deployment location of at least one of the suture securing devices advanced through the vessel wall.
Suture-tension and longitudinal-axis movement to close the puncture
Retracting the needle guides to release the suture securing devices distally of the vessel wall and establishing tension in the sutures to move the suture securing devices toward each other to thereby close the puncture, or moving the suture securing device toward a longitudinal axis of the guide member to close the puncture.
Securing device structure with elongated body, inner cavity, cutout, and tissue-engaging elements
Providing a suture securing device comprising an elongated body having a proximal end, a distal end, and an inner cavity; a first opening in the proximal end in communication with the inner cavity; a cutout having a periphery extending distally from the first opening; a plurality of tissue-engaging elements at least partially surrounding the cutout; and a suture attached to the elongated body.
The independent claims collectively cover a closure method that combines deployable, angle-deflectable needle guides for penetrating the vessel wall, an anchor that is expanded laterally beyond the securing-device deployment location, and closure achieved by releasing suture securing devices and moving them toward the guide-member longitudinal axis, including securing-device embodiments having an elongated body, inner cavity, cutout, and tissue-engaging elements.
