Ion-selective compositions which comprise an ion carrier, a compound capable of solvating the ion carrier, and a supporting matrix are disclosed.The ion carriers of this invention are hemispherand compounds represented by the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are independently hydrogen, alkyl, alkenyl, cycloalkyl, aryl or a heterocyclic group; and X is benzyl or an electron donating group capable of forming at least one coordinating site for sodium ions. A preferred hemispherand according to this invention is 2'-benzyloxy-3,3"-[2,6-pyridylenebis(methyleneoxymethylene)]-2,2"-tetramethylenedioxy-5,5',5"-trimethyl-1,1':3',1"-terphenyl. These compounds and the compositions containing same are particularly useful in ion-selective electrodes. Such an electrode is capable of selectively transporting sodium ions in preference to other cations. Dry-operative electrodes using these ion-selective compositions as membranes are also disclosed.
摘要:
A catheter configured for performing reperfusion by alternatively occluding a vessel so as to prevent fluid flow and removing that occlusion to allow fluid flow is described. A first catheter includes an outer member and a retractable valve to allow and prevent fluid flow in the vessel. A second catheter includes a sheathed expansion member that can be deployed and recaptured to prevent and allow, respectively, fluid flow. A third catheter includes an angioplasty balloon to open a vessel occlusion, in which an occlusion balloon is used to allow and disallow fluid flow. A fourth catheter includes an expandable member for providing mechanical plunging action to urge thrombotic material to a more distal location. A fifth catheter includes an accessory catheter that can be used to perform reperfusion with another catheter. A sixth catheter includes an inner balloon within an outer balloon configured to perform reperfusion.

Systems and compositions comprising paclitaxel and a second drug, such as rapamycin, analogs, derivatives, salts and esters thereof are disclosed, as well as methods of delivery wherein the drugs have effects that complement each other. Medical devices comprising supporting structures capable of including or supporting a pharmaceutically acceptable carrier or excipient, which carrier or excipient can contain one or more therapeutic agents or substances, with the carrier preferably including a coating on the surface thereof, and the coating including the therapeutic substances, such as, for example, drugs. Supporting structures for the medical devices that are suitable for use in this invention include coronary stents, peripheral stents, catheters, arterio-venous grafts, by-pass grafts, and drug delivery balloons used in the vasculature. These compositions and systems can be used in combination with other drugs, including anti-proliferative agents, anti-platelet agents, anti-inflammatory agents, anti-thrombotic agents, cytotoxic drugs, agents that inhibit cytokine or chemokine binding, cell de-differentiation inhibitors, anti-lipaedemic agents, matrix metalloproteinase inhibitors, cytostatic drugs, or combinations of these and other drugs.
摘要:
Disclosed is an interventional device for delivery of therapeutic agents from an angioplasty balloon and from a prosthesis such as an intraluminal stent. The invention also relates to the method of loading the beneficial agents onto the balloon and the device, as well as the method of delivery of the agents from separate surfaces. The invention also relates to an interventional device having a prosthesis surface that is loaded with a first beneficial agent, and a balloon surface loaded with a second beneficial agent. The invention also relates to a method of loading multiple beneficial agents onto the prosthesis surfaces and the balloon surfaces, and to a method of manufacturing an interventional device for the delivery of a first beneficial agent and a second beneficial agent from separate surfaces.
