The present invention relates to a drug delivery system for use in the treatment of vascular and vessel-related pathologies, comprising a drug delivery platform that comprises at least one compound capable of exerting an effect on the formation and/or maintenance of a thrombus in the vessel to be treated. The platform is preferably formed by liposomes that are sterically stabilized by grafting of poly(ethylene glycol) onto the liposome surface. The liposomes may further comprise photosensitizers and targeting molecules. The liposomes may be thermosensitive. The compound is suitably tranexamic acid. The drug delivery system is preferably used for the treatment of port wine stains.
A device for performing target activated transfer that includes a mounting surface for mounting a tissue sample; and a light source positioned to substantially uniformly irradiate both stained and unstained regions of the tissue sample with light energy that activates the reagent to selectively adhere the stained regions to a transfer surface. Also described is an automated system for transferring tissue from a tissue sample to a transfer substrate. The system includes means for holding a tissue section that includes targets specifically stained with an absorptive stain thereby resulting in a stained tissue surface, and a flexible transfer film that includes a lower thermoplastic layer in sufficient thermal contact with the stained tissue surface; an irradiating assembly configured to provide a predetermined uniform light dose to the entire tissue section; and means for applying a constant pressure to the transfer film during irradiation.

A method of removing a target from a biological sample which involves placing a transfer surface in contact with the biological sample, and then focally altering the transfer surface to allow selective separation of the target from the biological sample. In disclosed embodiments, the target is a cell or cellular component of a tissue section and the transfer surface is a film that can be focally altered to adhere the target to the transfer surface. Subsequent separation of the film from the tissue section selectively removes the adhered target from the tissue section. The transfer surface is activated from within the target to adhere the target to the transfer surface, for example by heating the target to adhere it to a thermoplastic transfer surface. Such in situ activation can be achieved by exposing the biological sample to an immunoreagent that specifically binds to the target (or a component of the target). The immunoreagent can alter the transfer surface directly (for example with a heat generating enzyme carried by the immunoreagent), or indirectly (for example by changing a characteristic of the target). In some embodiments, the immunoreagent deposits a precipitate in the target that increases its light absorption relative to surrounding tissue, such that the biological specimen can be exposed to light to selectively heat the target. Alternatively, the immunoreagent is an immunofluorescent agent that carries a fluorophore that absorbs light and emits heat.
