Interstitial microwave system and method for thermal treatment of diseases
A minimally-invasive fluid-cooled insertion sleeve assembly, with an attached balloon and distally-located penetrating tip, into which sleeve any of a group comprising a rigid rod, a microwave-radiator assembly and an ultrasonic-imaging transducer assembly may be inserted, constitutes a probe of the system. The sleeve assembly comprises spaced inner and outer plastic tubes with two fluid channels situated within the coaxial lumen between the inner and outer tubes. The fluid coolant input flows through the fluid channels into the balloon, thereby inflating the balloon, and then exits through that coaxial lumen. An alternative embodiment has no balloon. The method employs the probe for piercing sub-cutaneous tissue and then ablating deep-seated tumor tissue with microwave-radiation generated heat.

Tissue-mimicking phantom for prostate cancer brachytherapy
A phantom for prostate cancer brachytherapy has a prostate tissue phantom shaped like a real prostate gland, a perineal tissue phantom surrounding the prostate tissue phantom, a skin tissue phantom separating the perineal tissue phantom from an outside environment, and an enclosure. The prostate tissue phantom is a polyvinyl alcohol cryogel (PVA-C) having undergone 3-5 freeze-thaw cycles and having 10-20% w / w PVA in a solvent (e.g. water), 4-8% w / w oil and an amount of acoustic scattering particles to ultrasonically distinguish the prostate-tissue phantom from its surroundings. The perineal tissue phantom is a PVA-C having undergone 1-2 freeze-thaw cycles and having 10-20% w / w PVA in a solvent, 4-8% w / w oil and an amount of acoustic scattering particles to ultrasonically distinguish the perineal tissue phantom from its surroundings. The skin tissue phantom is a PVA-C having undergone at least 6 freeze-thaw cycles and having 15-25% w / w PVA in a solvent. The phantom mimics the imaging and mechanical properties of the prostate and surrounding tissues, providing a realistic phantom for prostate cancer brachytherapy.

ActiveUS20070161881A1Overcome difficultiesElectrocardiographyMedical devicesGlucose polymersD-Glucose
A method and an apparatus for measuring glucose level in the body fluid of a subject, typically blood glucose level, by measuring impedance of a body tissue, with two pairs of electrodes, two electrodes for injecting current into a body tissue and two electrodes for detecting the ensuing voltage of the body tissue. The body tissue is typically a sub-dermal or sub-cutaneous tissue. The measured impedance of the body tissue is used to correlate with directly determined glucose levels to determine the glucose level from the measured impedance. It is thus possible to determine body fluid glucose levels in a reliable and reproducible manner.

Decellularized biomaterial from non-mammalian tissue
ActiveUS20150352257A1Lower immune responseReduce inflammationPeptide/protein ingredientsEpidermal cells/skin cellsCellular componentFunctional integrity
The growth factor profile, connective tissue matrix constituents, and immunoprivileged status of urodele extracellular matrix (ECM) and accompanying cutaneous tissue, plus the presence of antimicrobial peptides there, render urodele-derived tissue an ideal source for biological scaffolds for xenotransplantation. In particular, a biological scaffold biomaterial can be obtained by a process that entails (A) obtaining a tissue sample from a urodele, where the tissue comprises ECM, inclusive of the basement membrane, and (B) subjecting the tissue sample to a decellularization process that maintains the structural and functional integrity of the extracellular matrix, by virtue of retaining its fibrous and non-fibrous proteins, glycoaminoglycans (GAGs) and proteoglycans, while removing sufficient cellular components of the sample to reduce or eliminate antigenicity and immunogenicity for xenograft purposes. The resultant urodele-derived biomaterial can be used to enhance restoration of skin homeostasis, to reduce the severity, duration and associated damage caused by post-surgical inflammation, and to promote progression of natural healing and regeneration processes. In addition, the biomaterial promotes the formation of remodeled tissue that is comparable in quality, function, and compliance to undamaged human tissue.

Method for making a fowl wing cut and the resultant product
The present invention is a method for cutting a fowl to create a meat cut which includes the radius bone and muscles (meat) adhering to the radius bone. The method involves separating the radius bone and muscles adhering to the radius bone from the carcass of the fowl, and then removing the radius bone and muscles adhering to the radius bone from the carcass of the fowl. The meat cut may be produced with the cutaneous tissues attached to the muscles adhering to the radius bone or with the cutaneous tissues removed from the muscles adhering to the radius bone to produce a skinless meat cut. The resulting meat cut contains a larger percentage of meat and is easier to consume. Alternatively, a portion of the muscles (meat) adhering to the radius bone can be removed to create a meat cut having less meat.
