A delivery system for delivering an implant to a first space within a body of a patient including an elongate delivery member having a proximal portion, a distal portion, a lumen and a receiving area, the receiving area dimensioned for receipt of the implant. A deforming member is movable with respect to the delivery member from a first position to a second position to apply a force to the implant to deform the implant positioned in the receiving area of the delivery member.

A customized guide includes a body having a shape corresponding to a main vessel in biological tissues that includes the main vessel and an accessory vessel branching from the main vessel, and an indicator provided in the body to indicate a branching location of the accessory vessel.

A vein cover that can reduce or prevent intimal thickening by delivering blood to the downstream veins while gradually buffering the blood pressure, pulse pressure, and blood flow rate of the blood flowing through the lumen is provided.

A cylindrical vein cover (10) is to be placed outside a vein (4) that is anastomosed to an artery (3) or to an artificial vessel (5), and has a portion (A) that has a 10% elastic index of 25 N or less when the inner diameter of the vein cover (10) is expanded by 10% from its natural state.

A protection cover (1) for an anastomotic part in which a first blood vessel is joined to a second blood vessel, having a tubular portion (2) that is configured to cover an outside of the first blood vessel, and a planar portion (4) that is configured to cover an outside of the second blood vessel, the protection cover (1) comprising a knitted fabric which is formed from continuous yarn extending from the tubular portion (2) to the planar portion (4).

Provided herein are novel devices for the formation of arteriovenous fistulas, which may aid subjects in need of hemodialysis. The novel devices are provided in a non-surgical procedure, greatly decreasing the cost and increasing the convenience of placing an arteriovenous fistula. The devices are atraumatic, and consist of a sutureless anastomosis device and conduit. Methods and tools for placing the devices in vivo are disclosed, including a magnetic-assisted method.

A vascular prosthesis configured to be implanted in a vessel, having substantially a T-shape, comprises a proximal tubular part forming the base of the “T” and a distal tubular part forming the head of the “T”. The proximal tubular part has a first lumen, the distal tubular part has a second lumen, and the first and second lumens are fluidly connected to form a common lumen. The distal tubular part comprises a first end portion, a second end portion, and an intermediate portion extending axially between the first and second end portions. The first and second end portions are radially expandable. The proximal tubular part is connected to the intermediate portion and the second end portion is movable between a retracted position in which the second end portion is axially restrained and a deployed position in which the second end portion is axially deployed.

The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for placing the muscularis layers of first and second body lumens in contact to establish a long term or permanent open flow or access passage therebetween.

Universal endovascular grafts are provided for evaluation and repair of damaged or aneurismal blood vessels. More particularly, the present invention relates to universal fenestrated and universal branched endografts for repair of blood vessels with branches, methods for implanting the endografts in the vessel and for making connection with one or more branches. The universal fenestrated endografts have a body with a first end, a second end, a first wall, a second wall, and an interior passage or lumen. The body further includes openings in communication with the passage at the first and second ends and one or more lateral fenestrations in communication with the lumen. The body further has a necked portion between the ends and a cannulation member. The universal branched endografts have a tubular body with a main lumen and four branch lumens. A large branch extends from the body. The four lumens are positioned about a circumference of the tubular body.

The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for body lumen access and/or drainage, and devices and methods for creating an open flow passage between two or more body lumens.

Devices and methods divert blood flow from a first vessel to a second vessel and maintain blood flow in the first vessel. The device includes a first segment and a second segment. The first segment is configured to anchor in the first vessel. The first segment includes a window to allow blood to flow into the first segment, through the window, and distal in the first vessel. The second segment is configured to anchor in the second vessel. The second segment is configured to allow blood to flow into the first segment, through the second segment, and into the second vessel.
