Intravascular blood conditioning device and use thereof
First Claim
1. An implantable, intravascular device for treating a disorder associated with the presence of a pre-selected molecule in the blood stream of an animal, the device comprising:
- (a) an anchor immobilizable to an inner wall of an intact blood vessel which, when immobilized in the vessel, permits blood in the vessel to pass therethrough; and
(b) a cartridge containing a converting agent, wherein the cartridge when introduced into the blood vessel is retained by the anchor and permits blood in the vessel to pass therethrough, and the converting agent converts or modifies the pre-selected molecule that enters the cartridge from the blood stream so as to remove the pre-selected molecule from the blood stream.

Abstract
Disclosed is an implantable, intravascular device for treating a medical disorder associated with the presence of a particular molecule in the systemic circulation of a mammal. When implanted, the device removes or reduces the concentration of the molecule in the blood stream thereby conditioning the blood. The device includes an anchor component immobilizable to an inner wall of an intact blood vessel and a cartridge component that is retained in place within the blood vessel by the immobilized anchor. The cartridge contains a converting agent, for example, viable cells or enzyme preparations, that catabolize or convert the molecule of interest into one or more other molecules that are not associated with the disorder. The invention also provides a minimally or non-invasive method for introducing into and, optionally, removing from the blood vessel the device of the invention.

23. A cartridge for implantation into a lumen of a blood vessel for treating a disorder associated with the presence of pre-selected molecule in the blood stream of an animal, the cartridge comprising:
-
a wall defining an inner volume and defining a plurality of pores passing therethrough dimensioned to permit entry of the pre-selected molecule into the inner volume; and
a converting agent disposed within the inner volume capable of converting or modifying the pre-selected molecule, wherein the cartridge, when introduced into a blood vessel, permits blood to pass through the vessel and removes the pre-selected molecule from the blood stream.

33. A method of treating a disorder associated with the presence of a pre-selected molecule in the blood stream of an animal, the method comprising the steps of:
-
(a) introducing into a lumen of a blood vessel in the animal a cartridge containing a converting agent capable of catabolizing the pre-selected molecule; and
(b) anchoring the cartridge within the blood vessel. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40)
