An endovascular implant for forming a fistula includes a body including a wall forming a lumen having a distal opening and a proximal opening. An anchor is coupled to a distal end of the body adjacent the distal opening. The anchor may include a first anchor extending from a first side of a distal end of the body, and a second, separate anchor may extending from a second side of the distal end of the body. A retriever may be coupled to a proximal end of the body adjacent the proximal opening.

Ports for accessing a vessels within a patient include passageways that can guide needles or other access devices directly into the vessels. The ports can be implanted subcutaneously within a patient. Some ports may be used in the creation and use of vascular access buttonholes.

Provided herein is a system including, in some embodiments, a streamlined port and a port tunneler. The port includes a septum and a stabilizing element. The septum is disposed over a cavity in a body of the port, and the septum is configured to accept a needle therethrough. The stabilizing element is configured to stabilize the port in vivo and maintain needle access to the septum. The port tunneler includes an adapter and a release mechanism. The adapter is in a distal end portion of the port tunneler, and the adapter is configured to securely hold the port while subcutaneously tunneling the port from an incision site to an implantation site for the port. The release mechanism is configured to release the port from the adapter at the implantation site for the port.

Apparatus and methods for controlled arterial/venous access are provided. The apparatus and methods may include a lumen anastomosed to a bodily lumen. A lumen clamping means may utilize a clamp manipulator to effectively seal the tubing, and the manipulator may be operated by two fingers. A needle receptor may be utilized, and the receptor may utilize a compressible member to seal tightly against a needle inserted from outside the body, in order ensure secure placement into a channel. The channel may be in liquid communication with the tubing. The manipulator and the needle receptor may be palpable from outside the body.

A lubrication device for lubricating a joint of a human or mammal patient, which is entirely implantable in a patient's body, comprises a reservoir for storing a lubricating fluid and a fluid connection for introducing the lubricating fluid into the joint when the device is implanted in the patient's body. Further, the fluid connection comprises a fluid connection device connecting the reservoir with the joint such that a lubricating fluid flow is established from the reservoir into the joint. The fluid connection comprises either an infusion needle adapted to be intermittently placed into the joint for injecting the lubricating fluid, or a tube adapted to be permanently placed into the joint for continuously injecting the lubricating fluid.

System and method for accessing and treating a patient's cerebrospinal fluid. The system comprises a device with at least one implantable single or multilumen catheter, configured for placement along a patent's cerebrospinal fluid pathway, with at least one domed subcutaneous reservoir and/or pump connected to the catheter(s). The device can also be equipped with control circuitry and controllable valves. The devices allow for drug administration and/or simultaneous, bidirectional cerebrospinal fluid access and exchange. The catheter(s), may be coupled with medical probes that transmit sensor data to the device's processor, which can be configured transmit and receive data and instructions. The catheters may also be configured with guide devices to facilitate implantation. Various configurations, from single dome to multiple dome devices are taught, along with various applications such as epidural and other cerebrospinal drug administration, and various medical diagnostic applications.

Implantable ports used for intravenous administration and methods of using the same.

A medical device comprises a flexible member that can be adhesively attached to a housing of the medical device, allowing implantation of the medical device into a body through an incision of reduced size. The flexible member can be attached to the housing either before or after implantation into the body. The flexible member comprises suture locations, including a permeable membrane or a suture hole, for suturing the medical device to tissue of the body. The suture holes can be filled with a substance penetrable by a suture needle, to minimize tissue ingrowth before or after suturing.

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.

According to embodiments of the present invention, a subcutaneous implant delivery apparatus is provided. The apparatus includes a receiving portion configured to receive a subcutaneous implantable device; and a stabilizing portion configured to cooperate with the receiving portion to hold the subcutaneous implantable device in a fixed position. The receiving portion and the stabilizing portion are movable relative to each other between a released configuration, wherein the receiving portion and the stabilizing portion are configured to move apart from each other to allow the receiving portion to be inserted under a skin layer, and a closed configuration, wherein the receiving portion and the stabilizing portion are configured to move toward each other to allow the subcutaneous implantable device to be held adjacent to the skin layer. According to further embodiments of the present invention, a method of delivering a subcutaneous implantable device for accessing a vascular site is also provided.
