Injectable hyaluronic acid derivative with pharmaceuticals/cells
Patent Number: 7,157,080This patent covers specific types of hyaluronic acid derivatives that are useful for administering cells into a soft tissue that is injured. Specifically, the patent is useful for treatment of intra-articular injuries by providing a means to administer cells so that the cells will be able to take the particular in vivo shape that is unique to the patient being treated. The patent has 2...
Valve treatment catheter and methods
Patent Number: 7,244,242This patent covers a deliver catheter for treatment of various heart conditions, especially valvular degeneration. The catheter is designed in such a method that stem cell administration can be performed with it.
System for administering a combination of therapies to a body lumen
Patent Number: 6918869This patent teaches ways of administering agents into the lumen of a body, agents including stem cell therapy. The patent seems to cover methods of administering agents in a manner that does not induce restenosis. The patent has 3 independent claims, which are: A system for delivering a biologically active material to a surface of a body lumen exposed to a radioactive source comprising...
Hydrogels formed by non-covalent linkages
Patent Number: 6949590Hydrogels are very useful for adminstration of cells into localized tissues. One of the problems is that polymerization of hydrogels often uses catalysts, which add problems to medical implimentation due to adverse effects of catalysts. This invention teaches ways of making hydrogels so that they do not require catalysts. The invention has 3 independent claims. The first covers "...
Injection devices that provide reduced outflow of therapeutic agents and methods of delivering therapeutic agents
Patent Number: 7070582This patent is a medical device useful for administration of therapeutic agents into a host, through a unique 2 catheter approach that can simultaneously deliver various agents including stem cells. The device if very interesting since it does not require a needle, but includes alternative delivery methods for implatnation of therapeutic solutions and cells into tissue in a localized...
Bucky paper as a support membrane in retinal cell transplantation
Patent Number: 7,135,172Retinal degeneration is a major cause of blindness, percipitated by numerous conditions, including adult macular degeneration. While numerous companies are currently seeking ways of blocking angiogenesis and thereby blocking the retinal degeneration process, when this process has already occurred, there are no options for treatment. Intensive research is being carried out on ways of using...

Selected cell delivery for heart failure
Patent Number: 7097833This patent is relevant for parties seeking to induce regeneration of cardiac tissue, or other tissue. Although the specification teaches the use of a variety of various peripheral blood and bone marrow stem cell sources for implantation into diseased, damaged, or otherwise subfunctional cardiac tissue, the issued claims only appear to cover the use of autologous, naturally residing cardiac...
Resorbable structure for treating and healing of tissue defects
Patent Number: 7049348Porous medical implants are covered by this patent that can be used to administer either stem cells, stem cell activating compositions of matter, or also just administered directly to allow for tissue re-growth on an injured area. The patent has one independent claim that covers the "porous polymeric device". The assignee, Kensey Nash corporation has a variety of implants/medical...
Deflectable microimplant delivery system
Patent Number: 7033345This invention covers a medical device that can be used for administration of a variety of drugs and/or cellular therapeutics. The patent essentially describes a "deflectable microimplant delivery system" that can be used for relatively non-invasive introduction of cells or agents into areas of need. The patent has numerous independent claims covering the various mechanical aspects of...
