20080262483METHOD FOR REMOVING PERMANENT TISSUE MARKINGS - A method of removing markings, such as a tattoos, from the tissue of a subject that includes steps of generating one or more shock wave pulses external to the subject's body and focusing the one or more shock wave pulses within one or more portions of the tissue, each of the one or more portions of the tissue containing at least a portion of the markings. The markings are typically caused by a plurality of pigment particles contained in the tissue, and the focusing step causes fragmentation of the particles so that they can be eliminated by the body.10-23-2008
20090004153MUSCLE DERIVED CELLS FOR THE TREATMENT OF URINARY TRACT PATHOLOGIES AND METHODS OF MAKING AND USING SAME - The present invention provides muscle-derived progenitor cells that show long-term survival following transplantation into body tissues and which can augment soft tissue following introduction (e.g. via injection, transplantation, or implantation) into a site of soft tissue. Also provided are methods of isolating muscle-derived progenitor cells, and methods of genetically modifying the cells for gene transfer therapy. The invention further provides methods of using compositions comprising muscle-derived progenitor cells for the augmentation and bulking of mammalian, including human, soft tissues in the treatment of various functional conditions, including malformation, injury, weakness, disease, or dysfunction. In particular, the present invention provides treatments and amelioration for urinary incontinence and other urinary tract pathologies.01-01-2009
20090010897Muscle derived cells for the treatment of cardiac pathologies and methods of making and using the same - The present invention provides muscle-derived progenitor cells that show long-term survival following transplantation into body tissues and which can augment soft tissue following introduction (e.g. via injection, transplantation, or implantation) into a site of soft tissue. Also provided are methods of isolating muscle-derived progenitor cells, and methods of genetically modifying the cells for gene transfer therapy. The invention further provides methods of using compositions comprising muscle-derived progenitor cells for the augmentation and bulking of mammalian, including human, soft tissues in the treatment of various cosmetic or functional conditions, including malformation, injury, weakness, disease, or dysfunction. In particular, the present invention provides treatments and amelioration for dermatological conditions, gastroesophageal reflux, vesico-ureteral reflux, urinary incontinence, fecal incontinence, heart failure, and myocardial infarction.01-08-2009
20090036945METHODS AND SYSTEMS FOR ACHIEVING A PHYSIOLOGICAL RESPONSE BY PUDENDAL NERVE STIMULATION AND BLOCKADE - Methods and apparatus are therefore provided herein for stimulating a desired physiological effect. The methods and apparatus can be used to control micturition, defecation and/or ejaculation. The methods and apparatus also can be used to control pain in the lower pelvic region, for example and without limitation, interstitial cystitis. The methods and apparatus also can be used to increase sexual sensation.02-05-2009
20100104631METHOD OF TREATMENT FOR BLADDER DYSFUNCTION - Liposomes are used for intravesical drug delivery, especially delivery of botulinum toxin (BoNT) to help improve lower urinary tract symptoms by decreasing bladder irritation and frequency. The system uses a lower and safer dose of BoNT with lower risk of urinary retention. A simple instillation of liposome-BoNT as a liquid formulation into the bladder, in a typical volume of 30-60 ml, will achieve efficacy similar to that currently achieved with cystscopic needle injection of BoNT. The dose may be lower than that done by injection, thereby causing significantly less risk of urinary retention. Liposome-BoNT can protect the BoNT from bladder and urine breakdown. Liposome-BoNT instillation is more comfortable for the patients and allows many more doctors' offices to offer this form of treatment that would otherwise be restricted to doctors skilled and certified in cystoscopic BoNT injection.04-29-2010
20100158875MUSCLE DERIVED CELLS FOR THE TREATMENT OF GASTRO-ESOPHAGEAL PATHOLOGIES AND METHODS OF MAKING AND USING THE SAME - The present invention provides muscle-derived progenitor cells that show long-term survival following transplantation into body tissues and which can augment soft tissue following introduction (e.g. via injection, transplantation, or implantation) into a site of soft tissue. Also provided are methods of isolating muscle-derived progenitor cells, and methods of genetically modifying the cells for gene transfer therapy. The invention further provides methods of using compositions comprising muscle-derived progenitor cells for the augmentation and bulking of mammalian, including human, soft tissues in the treatment of various cosmetic or functional conditions, including malformation, injury, weakness, disease, or dysfunction. In particular, the present invention provides treatments and amelioration of symptoms for gastro-esophageal pathologies like gastro-esophageal reflux.06-24-2010
20100166739Methods and Compositions for Diagnosing Urological Disorders - It has been discovered that cytokines, chemokines, and growth factors in urine are biomarkers indicative of urological disorders including interstitial cystitis/painful bladder syndrome and overactive bladder syndrome. Preferred chemokine biomarkers are CCL2, CCL4 (MIP-1β), CCL11, CXCL1 (GRO-α), sCD40L, IL-12p70/p40, IL-5, sIL-2Rα, IL-6, IL-10, IL-8, and EGF. The concentration of one or more of these chemokines in an urine sample can be used to assist in the diagnosis of urological disorders. Methods for evaluating the effectiveness of treatments for urological disorders and for assessing the severity of urological disorders are also provided.07-01-2010
20110223139RAPID PREPARATION OF STEM CELL MATRICES FOR USE IN TISSUE AND ORGAN TREATMENT AND REPAIR - A rapid method for preparing stem cell and physiologically acceptable matrix compositions for use in tissue and organ repair is described. Compared with previous tissue engineering materials, the stem cell-matrix compositions of the present invention do not require long-term incubation or cultivation in vitro prior to use in in vivo applications. The stem cells can be from numerous sources and may be homogeneous, heterogeneous, autologous, and/or allogeneic in the matrix material. The stem cell-matrix compositions provide point of service utility for the practitioner, wherein the stem cells and matrix can be combined not long before use, thereby alleviating costly and lengthy manufacturing procedures. In addition, the stem cells offer unique structural properties to the matrix composition which improves outcome and healing after use. Use of stem cells obtained from muscle affords contractility to the matrix composition.09-15-2011
