A system comprising: a hollow tube having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end; at least a portion of the tube comprising a porous membrane; and a gas-rich perfluorocarbon solution incorporated in the porous membrane; wherein the porous membrane has a porosity in the range of 0.001-200 microns, in order that: (i) the gas-rich perfluorocarbon solution is effectively incorporated into the porous membrane; and (ii) when the porous membrane is positioned in blood, the gas-rich perfluorocarbon solution elutes out of the porous membrane, in aggregations small enough to prevent the creation of embolisms in the blood, with the elution of the gas-rich perfluorocarbon solution into the blood varying between minutes and several hours, depending on the temperature and the hemodynamics of the blood.

Method and apparatus for delivering oxygen and/or other gases to tissue

An apparatus for inserting particles (P) into a tissue (G), in particular a muscle tissue, wherein the apparatus () essentially represents a tubular body () with one closed end and comprises at least one sleeve (), at least one positioning element (), at least one outlet area (), which extends over the entire circumference of the tubular body (), at least one thrust means () for the particles (P), as well as an actuating device for the outlet area (), and wherein the outlet area () is formed by a plurality of flexible elements (), which are at least attached to the sleeve (), which butts against the outlet area () in the axial direction, or the positioning element () in such a way, that in a tense condition the diameter of the outlet area () is larger than the diameter of the sleeve (), and openings are present between the elements ().

Apparatus for inserting particles into tissue, in particular muscle tissue

The present invention comprises a vascular filter system for non-permanent application which is provided with a guide wire, a filter membrane having an inner area provided in the area of the proximal end of the guide wire and a free outer area, and an umbrella structure provided at least on the outer area of the filter membrane, made of a flexible material and permitting opening and closing of the umbrella formed by the umbrella structure and filter membrane, characterized in that the system has contactless structure for closing the umbrella. The structure can be of a magnetic nature or involve mechanisms based on temperature changes.
