摘要： Photoactive materials, such as photosensitizers, are used as fluorescent markers for in vivo detection of the distribution of the injected filler material during cosmetic treatments. In one preferred embodiment, liposomal formulated temoporfin is used, as the photoactive component, in very small concentrations along with fillers for cosmetic and wound healing applications. Fillers, which can be used in the invention, include collagen, hyaluronic acids and other synthetic or natural products which are generally used in wound healing, scar reduction and other such medical applications. In a preferred embodiment, the formulated photosensitizer is coupled to the filler so that tracking is possible over longer periods of time A liposomal formulated photosensitizer is injected with the fillers into the treatment area, and is irradiated with laser light shortly after injection. The emitted fluorescence is measured by a special non-invasive device. Thereby it is possible to monitor the injection site and the distribution of the injected solution around the injection site. When irradiated with laser or other light source, the fluorescence of the photosensitizer is detected using a fluorescence detector, which permits tracking the filler at injection site and in the injection volume.

摘要： Pharmaceutical liposomal formulations are described for photodynamic therapy comprising a, hydrophobic porphyrin photosensitizer, a monosaccharide and one or more synthetic phospholipids, which are stable in storage especially through freeze-drying process. The liposomal formulations provide therapeutically effective amounts of the photosensitizer for intravenous administration. In particular derivatives of chlorins and bacteriochlorins, such as temoporfin, are, hydrophobic photosensitizers whose efficacy and safety are enhanced by such liposomal formulations. The formulation can be efficiently freeze-dried preserving the size of the liposomal vehicles, and the content of a therapeutically effective amount of the photosensitizer, due to the selection of phospholipids and monosaccharides. The invention also relates to liposome compositions formed upon reconstitution with an aqueous vehicle. The freeze-dried formulation upon reconstitution with a suitable aqueous vehicle forms liposomes that are useful for intravenous administration.

摘要： Pharmaceutical pegylated liposomal formulations for photodynamic therapy are presented. The pegylated liposomal formulation provides therapeutically effective amounts of the photosensitizer for intravenous administration. At least one of the phospholipids in the liposomes has been linked with poly ethylene glycol (PEG) as an integral part of the phospholipids. The formed pegylated liposomes contain the hydrophobic photosensitizer within the lipid bilayer membrane. Pegylation of liposomes carrying the hydrophobic photosensitizer helps to maintain the drug level within the therapeutic window for longer time periods and provides the drug a longer circulating half life in vivo. Further the pegylated formulation of hydrophobic photosensitizers shows improved pharmacokinetics over standard non-liposomal formulations thus enhancing the efficacy of PDT with the pegylated liposomal formulations.

摘要： A method and a composition for photochemical cross linking of collagen by photoactive agent in-vivo are presented. The method includes a non-toxic photoactive formulation of the composition with collagen, which is administered to treatment area locally; followed by irradiation with suitable wavelength. In one of the embodiment liposomal formulated mTHPC is added to the collagen and is irradiated with a 652 nm laser, resulting in producing efficient collagen scaffolds with strengthen and stabilized microstructure, thus improving the physiochemical properties of the collagen scaffold. It improves the thermostability, mechanical property and swelling ratio of newly formed scaffold. Photochemical cross-linked collagens shows antimicrobial effect, when irradiated with suitable wavelength it disinfects the treatment site and curbs microbial growth.

摘要： Pharmaceutical liposomal formulations for photodynamic therapy are presented, which are stable in storage as liquid formulations, comprise a hydrophobic photosensitizer and one or more synthetic phospholipids. The liposomal formulations provide therapeutically effective amounts of the photosensitizer for intravenous administration. The formed liposomes contain the hydrophobic photosensitizer within the lipid bilayer membrane. In the present formulation the size of the liposomal vehicles and their content of a therapeutically effective amount of the photosensitizing agent remain unchanged over storage times of a year or more, thus making the liquid formulations commercially viable. Being stable in the liquid state also makes them easy to store, and easier to use for doctors and patients. They can be prepared in a ‘factory setting’ delivered to practitioners in a liquid state and be available for use in PDT related treatments as called for by the practitioners' patient needs.

摘要： A pharmaceutical liposomal formulation for photodynamic therapy comprising a non-polar porphyrin photosensitizer and one or more phospholipids, which are stable in storage without requiring freeze-drying is described. The liposomal formulation provides therapeutically effective amounts of the photosensitizer for intravenous administration. The phospholipids may be modified by pegylation, i.e. they contain poly ethylene glycol as an integral part of the phospholipids. The formed liposomes contain the non-polar photosensitizer within the membrane and are useful for the combined targeting of a non-polar photosensitizer and a second polar substance. When a formulation includes the presence of monosaccharides or polyalcohols, it can be efficiently freeze-dried preserving the size of the liposomal vehicles and the content of a therapeutically effective amount of the photosensitizing agent. The invention also relates to the liposome composition formed upon reconstitution with an aqueous vehicle. The freeze-dried formulation upon reconstitution with a suitable aqueous vehicle forms liposomes that are also useful for intravenous administration.

摘要： System and method for treating hemorrhoidal piles, addressing both cause and symptoms, by endoluminal/interstitial application of energy are disclosed. The dilated blood arteries in anal/rectal region are irradiated from inside the pile using (laser) energy for minimal pain/discomfort. The center of the pile is irradiated over a certain diameter, absorbing energy; and is denatured causing volume reduction. Central vessels located in the same diameter are obliterated immediately, relieving bleeding. During treatment, new connective tissue replaces the coagulated tissue. Closing inflowing arteries further shrinks piles in weeks to three months. Complications are highly diminished. A hand-piece and a fiber with a sharp distal tip are beneficial. Including an imaging system, (ultrasound imaging, optical coherence tomography) and an intelligent system to calculate necessary laser energy parameters help address each pile individually.

摘要： A noninvasive treatment of uterine growths such as myomas (fibroids) and polyps is presented. Treatment involves carrying out diagnostic hysteroscopy and ultrasound procedures to detect, measure, and evaluate unwanted uterine growths; then inserting optical fiber into a hysteroscope, reaching target tissue with optical fiber and eliminating said tissue or shrinking it to a size/shape for easy mechanical removal. Finally, ultrasound imaging is used to confirm success of procedure. In one embodiment, optical fiber has an off-axis firing end but can be inserted inside a conventional hysteroscopy device. In another embodiment, a laser interstitial thermal therapy (LITT) fiber is used to treat myomas found on the outside of the uterus. A high energy laser is used that can emit at wavelengths easily absorbed by water and blood, such as 980 nm and 1470 nm. Procedure is fast and can be done in the physician's office with little or no anesthesia used.
