Abstract: Apparatuses and methods for coating and/or loading a medical device with a therapeutic agent prior to or during the placement of the medical device within the patient's body. In one variation, the medical device is coated and/or loaded with a therapeutic agent while the device is positioned in a delivery apparatus. In another variation, the delivery apparatus comprises a reservoir for retaining a therapeutic agent. The user may release the therapeutic agent from the reservoir prior to or during the placement of the device to coat and/or load the device with the therapeutic agent.

Abstract: A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.

Abstract: 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.
