BIORESORBABLE DEVICE

Abstract

A system and method for vasculature closure from a single access point are provided, utilizing specifically designed bioresorbable devices. The bioresorbable devices may include a disk-shaped substrate layer with an opening extending from a first surface to a second surface, configured to allow a guidewire to pass through, and a coating configured to encourage adhesion to an interior vessel wall. The system utilizes a guidewire having an expandable portion passing through the opening. The bioresorbable device is carried into the blood vessel within a first tubular member in a compressed configuration, and then ejected from the first tubular member by a second tubular member. The bioresorbable member then assumes a partially expand configuration. The expandable portion of the guidewire can then be used to press the bioresorbable device against an interior vessel wall, allowing it to adhere, after which the expandable portion can be deflated.

Description

TECHNICAL FIELD

The present disclosure is drawn to devices, systems, and method for vasculature closure from a single access point.

BACKGROUND

Many treatment options require medical instruments to be inserted into a patient's vasculature. The techniques require that some form of vasculature closure in order to achieve hemostasis. There are several categories of conventional vascular access closure devices, including suture-mediated closure devices, mechanical non-suture closure devices, intra-vascular sealant devices, extra-vascular sealant devices and manual compression devices. One technique utilizes a resorbable disc that can be used at the access point, but to use it effectively generally requires another medical instrument be inserted contralaterally in order to provide the necessary force to adhere the disc to a desired location.

What is needed is a device, system, and method that allows for vasculature closure using a single access point.

Referring to FIG. 5, and also to FIGS. 4A-4F, a method may be provided for vasculature closure.

The method (800) may include inserting (810) a guidewire (500) that may include an expandable portion (510) into a subject, through an entry point (701) in a blood vessel (700).

The method may include inserting (820) a delivery system over the guidewire, through the entry point (701), and to a desired location in the blood vessel (700). The delivery system may include an embodiment of a system as disclosed herein. In some embodiments, the delivery system includes a first tubular member (300) having a proximal end and a distal end, and a first lumen extending therethrough, a second tubular member (400) having a proximal end and a distal end, and a second lumen extending therethrough, and an embodiment of a bioresorbable device as disclosed herein, positioned within the first lumen distally from the distal end of the second tubular member, the bioresorbable device being in a compressed configuration. The second tubular member may be slidably positioned within the first lumen such that the distal end is within the first lumen. The guidewire may extend through the opening in the bioresorbable device and through the second lumen. At this step, as seen in FIG. 4A, the bioresorbable device (100) is a first (e.g., compressed) configuration (103) within the first lumen, inside blood vessel (700). The expandable portion is in a non-expanded (e.g., compressed) configuration.

The method may include expanding (830) the expandable portion (510) of the guidewire to a diameter (511) that is less than a diameter of the blood vessel. In some embodiments, this may be a partially expanded diameter. At this step, as seen in FIG. 4B, the bioresorbable device (100) is a first (e.g., compressed) configuration (103) within the first lumen, inside blood vessel (700), while the expandable portion is in a partially expanded configuration.

The method may include repositioning (840) the second tubular member (400) to cause the distal end (402) of the second tubular member (400) to move distally towards the distal end (302) of the first tubular member (300), causing the bioresorbable device to exit the first lumen and exhibit a second configuration (104). The second configuration may be a partially expanded configuration. At this step, as seen in FIG. 4C, the bioresorbable device (100) has been moved distal from the distal end of the first lumen, and is now in a second (e.g., partially expanded) configuration (104), and the expandable portion is in a partially expanded configuration.

In some embodiments, the partially expanded configuration (104) is configured such that at least a portion (118) of the substrate layer extends radially beyond the outer surface (310) of the first tubular member (300). In some embodiments, the expandable portion may be separated from the bioresorbable device (100) by a first distance (520). In some embodiments, the distance may be at least 1 mm. In some embodiments, the expandable portion may be separated from the distal end (302) of the first tubular member by a second distance (521). In some embodiments, the distance may be at least 1 mm. In some embodiments, the first distance is greater than the second distance. In some embodiments, the first distance is less than the second distance. In some embodiments, the first distance is substantially equal to the second distance (e.g., the distances are within 5% of each other).

The method may include retracting 850 the guidewire with the expandable portion in a partially expanded position to move the expandable portion into contact with the bioresorbable device, and the bioresorbable device in contact with the first tubular member and/or second tubular member. This may be seen in FIG. 4D—the partially expanded expandable portion (510) may be in contact with the bioresorbable device (100). The bioresorbable device may be in a third configuration (105), different from the second configuration (104).

The method may include retracting (860) the first tubular member (300), second tubular member (400), bioresorbable device (100), and guidewire (500) together until the bioresorbable device is positioned over the entry point. This is seen in FIG. 4E, where the system is retracted until the bioresorbable device (100) is positioned over the entry point (701). In some embodiments, the coating is facing the blood vessel (700). In some embodiments, a portion of the coating is in contact with the blood vessel.

The method may include expanding (870) the expandable portion of the guidewire to fully oppose the bioresorbable device to a wall of the blood vessel. This is seen in FIG. 4F, where the diameter (512) of the expandable portion is increased, and at least a portion (705) of the blood vessel wall around the entry point (701) is in contact with the coating (120) on the bioresorbable device.

The method may include deflating (880) the expandable portion. This can be seen in FIGS. 4G-4H. The bioresorbable device remains in place over the entry point after the partially expandable portion (510) has been deflated.

In some embodiments, the method may include removing (895) the guidewire.

In some embodiments, the method may include inserting (805) an access device into the patient, and optionally into the entry point, prior to inserting the guidewire. In some embodiments, the method may include removing (815) the access device after inserting the guidewire. In FIG. 5, this is shown as occurring immediately after insertion of the guidewire, but this could occur at any later step in the process up to the point at which the guidewire is removed (see verifying (885) step).

In some embodiments, the method may include removing (865) the first tubular member (300) and second tubular member (400) after the bioresorbable device is positioned over the entry point, leaving the guidewire (500) in place. This can be seen in FIG. 4F, where by the time the expandable portion is fully expanded to a diameter (512), the first and second tubular members have been removed.

In some embodiments, the method may include verifying (885) that a desired level of hemostasis has been achieved.

In some embodiments, the method may include re-expanding (890) the expandable portion of the guidewire to fully oppose the bioresorbable device to a wall of the blood vessel.

In some embodiments, the method may include moving (887) the expandable portion distally from the bioresorbable device and re-expanding (890) the expandable portion of the guidewire. The deflating, verifying, and moving/reinflating steps may be repeated until the desired level of hemostasis is achieved, or until alternative approaches are determined to be necessary.
