System and methods for clot dissolution

Clot disruption and dissolution are achieved using a catheter having both an agitator and the ability to deliver a thrombolytic agent. The catheter is introduced to a target region with a blood vessel and the agitator manipulated to engage and disrupt a region of clot therein. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.

Intravascular methods and apparatus for isolation and selective cooling of the cerebral vasculature during surgical procedures

Patients having diminished circulation in the cerebral vasculature as a result of stroke or from other causes such as cardiac arrest, shock or head trauma, or aneurysm surgery or aortic surgery, are treated by flowing an oxygenated medium through an arterial access site into the cerebral vasculature and collecting the medium through an access site in the venous site of the cerebral vasculature. Usually, the cold oxygenated medium will comprise autologous blood, and the blood will be recirculated for a time sufficient to permit treatment of the underlying cause of diminished circulation. In addition to oxygenation, the recirculating blood will also be cooled to hypothermically treat and preserve brain tissue. Isolation and cooling of cerebral vasculature in patients undergoing aortic and other procedures is achieved by internally occluding at least the right common carotid artery above the aortic arch. Blood or other oxygenated medium is perfused through the occluded common carotid artery(ies) and into the arterial cerebral vasculature. Usually, oxygen depleted blood or other medium leaving the cerebral vasculature is collected, oxygenated, and cooled in an extracorporeal circuit so that it may be returned to the patient. Occlusion of the carotid artery(ies) is preferably accomplished using expansible occluders, such as balloon-tipped cannula, catheters, or similar access devices. Access to the occlusion site(s) may be open surgical, percutaneous, or intravascular.

Drug Delivery Methods, Structures, and Compositions for Nasolacrimal System

An implant for insertion into a punctum of a patient comprises a body. The body has a distal end, a proximal end, and an axis therebetween. The distal end of the body is insertable distally through the punctum into the canalicular lumen. The body comprises a therapeutic agent included within an agent matrix drug core. Exposure of the agent matrix to the tear fluid effects an effective therapeutic agent release into the tear fluid over a sustained period. The body has a sheath disposed over the agent matrix to inhibit release of the agent away from the proximal end. The body also has an outer surface configured to engage luminal wall tissues so as to inhibit expulsion when disposed therein. In specific embodiments, the agent matrix comprises a non-bioabsorbable polymer, for example silicone in a non-homogenous mixture with the agent.

Method of biochemical treatment of persistent pain

This invention relates to a method for the biochemical treatment of persistent pain disorders by inhibiting the biochemical mediators of inflammation in a subject comprising administering to said subject any one of several combinations of components that are inhibitors of biochemical mediators of inflammation. Said process for biochemical treatment of persistent pain disorders is based on Sota Omoigui's Law, which states: ‘The origin of all pain is inflammation and the inflammatory response’. Sota Omoigui's Law of Pain unifies all pain syndromes as sharing a common origin of inflammation and the inflammatory response. The various biochemical mediators of inflammation are present in differing amounts in all pain syndromes and are responsible for the pain experience. Classification and treatment of pain syndromes should depend on the complex inflammatory profile. A variety of mediators are generated by tissue injury and inflammation. These include substances produced by damaged tissue, substances of vascular origin as well as substances released by nerve fibers themselves, sympathetic fibers and various immune cells. Biochemical mediators of inflammation that are targeted for inhibition include but are not limited to: prostaglandin, nitric oxide, tumor necrosis factor alpha, interleukin 1-alpha, interleukin 1-beta, interleukin-4, Interleukin-6 and interleukin-8, histamine and serotonin, substance P, Matrix Metallo-Proteinase, calcitonin gene-related peptide, vasoactive intestinal peptide as well as the potent inflammatory mediator peptide proteins neurokinin A, bradykinin, kallidin and T-kinin.
