Intravascular drug delivery device and use therefor
First Claim
1. An intravascular drug delivery device for delivering a pre-selected drug into systemic circulation of an animal, the device comprising:
- (a) an anchor immobilizable to an inner wall of an intact blood vessel which, when immobilized in the blood vessel, permits blood in the vessel to pass therethrough; and
(b) a cell-free reservoir containing pre-selected drug, which when introduced into the blood vessel is retained by the anchor and releases the pre-selected drug into blood passing the reservoir.

Abstract
Disclosed is an implantable drug delivery device for delivering a pre-selected drug directly into the systemic circulation of an animal. The device comprises an anchor immobilizable to an inner wall of an intact blood vessel. The device also comprises a drug containing reservoir that is retained in place within the blood vessel by the immobilized anchor. The reservoir may include, for example, a drug containing osmotic pump or a drug permeable capsule having disposed therein drug containing particles, which release the drug directly into blood passing the reservoir. The invention also provides a minimally invasive method for introducing into a blood vessel and, optionally, removing from the blood vessel the drug delivery device of the invention.

21. A method of introducing into a blood vessel a drug delivery device for delivering a pre-selected drug directly into systemic circulation of an animal, the method comprising the steps of:
-
(a) immobilizing an anchor an inner wall of an intact blood vessel, which when immobilized permits blood in the vessel to pass therethrough;
(b) introducing into the blood vessel a cell-free reservoir containing pre-selected drug, such that when introduced into the blood vessel the reservoir releases the pre-selected drug into blood passing the reservoir; and
(c) permitting the reservoir to be retained in the blood vessel by the anchor. - View Dependent Claims (22, 23, 24, 25, 27, 28, 29, 31, 32, 33, 35, 36, 37, 38, 39, 40, 41, 42, 43)

26. An anchor for implantation into an intact blood vessel of an animal, the anchor comprising:
-
a first element adapted for immobilization to an inner wall of the blood vessel, wherein the first element comprises at least one member biased in a radially outward direction when immobilized in the blood vessel; and
attached theretoa second element forming a receptacle for receiving a drug delivery reservoir member of a predetermined configuration.

34. A drug delivery reservoir for implantation into an intact blood vessel of an animal, the reservoir comprising:
-
a first element forming an interlocking mechanism for engaging a receptacle of an anchor immobilizable to an inner wall of an intact blood vessel; and
attached theretoa second element having a wall at least partially defining an inner volume for retaining the drug and defining at least one pore dimensioned to permit the drug retained therein to pass therethrough.

44. An implantable, intravascular drug delivery device, the device comprising:
-
(a) an anchor comprising a first element adapted for immobilization to an inner wall of a blood vessel, wherein the first element comprises at least one member biased in a radially outward direction when immobilized in the blood vessel and, in connection therewith, a second element comprising a first interlocking mechanism; and
(b) a reservoir comprising a first element comprising a second interlocking mechanism and in connection therewith a second element having a wall at least partially defining an inner volume for retaining the drug and defining at least one pore dimensioned to permit the drug retained therein to pass therethrough, wherein the first interlocking mechanism is capable of engaging the second interlocking mechanism to the lock the reservoir to the anchor.
