20090004238 | IMPLANTATION OF ENCAPSULATED BIOLOGICAL MATERIALS FOR TREATING DISEASES - Methods of applying biocompatible coating materials around biological materials using photopolymerization while maintaining the pre-encapsulation status of the biological materials are disclosed. The coatings can be placed directly onto the surface of the biological materials or onto the surface of other coating materials that hold the biological materials. The components of the polymerization reactions that produce the coatings can include natural and synthetic polymers, macromers, accelerants, cocatalysts, photoinitiators, and radiation. Methods of utilizing these encapsulated biological materials to treat different human and animal diseases or disorders by implanting them into several areas in the body including the subcutaneous site are also disclosed. The coating materials can be manipulated to provide different degrees of biocompatibility, protein diffusivity characteristics, strength, and biodegradability to optimize the delivery of biological materials from the encapsulated implant to the host recipient while protecting the encapsulated biological materials from destruction by the host inflammatory and immune protective mechanisms without requiring long-term anti-inflammatory or anti-immune treatment of the host. | 01-01-2009 |

20100022889 | ULTRASOUND TREATMENT HEAD FOR AN APPARATUS FOR TREATING A PATIENT WITH ULTRASOUND - An ultrasound treatment head for an apparatus for treating a patient with ultrasound comprises at least one active element for converting an electric signal into ultrasound and a vacuum cup having an upper part and a lower part. The active element is mounted in the upper part and the vacuum cup provides a vacuum chamber with a holding space for a gel pad. The upper part is adapted to act as a spring suspension for the active element to lower the active element into the lower part. The active element is provided with a positioning ring protruding with respect to the active element. This positioning ring determines the location of the gel pad within the holding space. | 01-28-2010 |
