A vascular plug comprises a superstructure expandable from a collapsed percutaneous insertion configuration to an expanded deployment or use configuration. The superstructure is comprised of both primary and secondary three-dimensional shapes allowing for the occlusion of a wide range of vessel sizes from small to large through a disproportionately small delivery catheter. The plug includes a shape memory element for the generation of radial force and the creation of the larger secondary three-dimensional twisting or helical superstructure as is needed for target vessel occlusion.

A method and device for facilitating the anastomotic healing of a patient after a radical prostatectomy surgical procedure, without a urethral catheter, comprising the steps of performing a radical prostatectomy, fixedly positioning a splinting element between the urethra and the bladder, across the urethral opening, placing the splinting element during the performing of the radical prostatectomy and prior to surgical closure. The fixed positioning is effected from a position within the bladder with anchoring the splinting element in position relative to the interior of the bladder, setting a separate urine drainage tube, and removing the splinting element, after anastomotic healing, with a retrieval element on the splinting element or with dissolving of the splinting element.

Catheter-based devices and methods for endoluminally accessing and occluding hollow anatomical structures are disclosed. Occlusion clips are contained in one or more needles that pierce opposing walls of the anatomical structure to deploy the clips externally of the structure. The clips then are drawn together to press the opposing anatomical walls together.

Disclosed are embodiments of a method for occluding a left atrial appendage (LAA) and other cavities or openings within a body. Some embodiments of the method can include an implant configured to be deployed within the LAA or other cavity, configured to be expanded or moved against a wall portion of the LAA or other cavity, and configured to twist at least a portion of the LAA or other cavity when the implant is rotated. Thereafter, one or more securing elements, staples, sutures, or other fasteners can be implanted in the gathered tissue to hold the tissue in the gathered state, thereby occluding the opening of the LAA or other cavity. In some embodiments, the opening of the LAA or other cavity can be occluded by elongating or otherwise reshaping the opening using an implant device, and securing the opening in the occluded state.

Devices, methods and systems are provided for occluding a left atrial appendage. In one embodiment, a medical device includes a cover portion and a foam anchor portion with a flexible member coupled therebetween. The cover portion is configured to be positioned over an ostium of the left atrial appendage. The foam anchor portion extends between a proximal end and a distal end to define a length and an axis defined along the length of the foam anchor portion. The foam anchor portion defines a curved external surface radially extending relative to the axis such that the curved external surface extends between the proximal and distal ends of the foam anchor portion. The foam anchor portion is configured to self-expand to provide an outward biasing force from the curved external surface such that a circumferential surface area of the curved external surface biases against tissue of the left atrial appendage.

Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.

An occluder (1) with no externally protruding structure at either end, comprising a mesh body (10); a first closing line (20), the first closing line (20) passing through a plurality of grids formed by mesh at a first closing end (11) in order to implement closing of the first closing end (11); and a second closing line (30), the second closing line (30) passing through a plurality of grids formed by mesh at a second closing end (12) in order to implement closing of the second closing end (12). Compared to occluders in the prior art with a threaded connecting member, the present solution can reduce the manufacturing difficulty, reduce the reject rate, and save costs.

Example occlusive implants are disclosed. An example occlusive implant includes an expandable framework configured to shift between a collapsed configuration and an expanded configuration, an occlusive member disposed along at least a portion of the expandable framework and a first collar attached to the expandable framework. The occlusive implant also includes a sensor housing coupled to the first collar, the sensor housing having a first end and a second end opposite the first end and a second collar slidably disposed along an outer surface of the sensor housing. Further, the second collar is coupled to the expandable framework via a spring. The occlusive implant also includes a sensor disposed along the second end of the sensor housing.

A septal closure and port device for implantation in the atrial septum of a patient's heart comprises an expandable frame can comprise a central portion defining a lumen, and first and second opposing end portions. The frame is configured to expand and contract between a compressed, tubular configuration for delivery through the patient's vasculature and an expanded configuration in which the first and second end portions extend radially outwardly from the opposite ends of the central portion. The device can further comprise a valve member supported on the frame and positioned to block at least the flow of blood from the left atrium to the right atrium through the lumen of the frame. The valve member is configured to permit a medical instrument inserted through the lumen and into the left atrium, such as for performing a subsequent medical procedure in the left side of the heart.

An elongate resilient tube of a mesh of shape memory alloy is used to therapeutically occlude an opening in body tissue. The tube is compressible so that it can be delivered to the opening in the body within a catheter. The tube self-expands as it is released from the catheter to contiguously form, sequentially an outer perimeter structure and an inner perimeter structure disposed within the outer perimeter structure to conformingly engage an inner side of the outer perimeter structure, a plate shaped structure, and a flexible connector between them. J-shaped hooks extend from the perimeter structure to flexibly engage tissue of the body opening without piercing the tissue.
