Assignee:

Transport Pharmaceuticals, Inc. - Framingham MA

International Classification:

A61N 1/00

US Classification:

607115

Abstract:

An apparatus to monitor current density in the application of medicament to a treatment site of a mammalian user of a electrokinetic device including: an applicator cartridge including an active electrode, a matrix carrying a medicament or a medicament and an electrically conductive carrier; a device including an electrical power source connectable to the active electrode, a counter electrode, and an electronic circuit configured to control the application of electrical current through the active electrode to establish a conductive path extending from the power source, through the active electrode, matrix, the treatment site, the user and the counter electrode electrically connected to the power source, and an array of contacts monitoring current density flowing through the matrix and to the treatment site, wherein the array of sensors are arranged monitor the current density at various locations of the matrix and a contact area between the matrix and skin above the treatment site.

International Classification:

B01D 6306

US Classification:

210192

Abstract:

A device which serves as an artificial pancreas comprises a hollow fiber having an inner diameter of about 5 mm which is surrounded by islets of Langerhans enclosed in a housing. The islets are suspended in a semi-solid matrix which ensures desired distribution of the cells about the hollow fiber. The hollow fiber and suspended islets are enclosed in a housing which further aids the desired distribution of islets about the hollow fiber. The hollow fiber has a porosity which selectively allows passage of substances having a molecular weight of less than about 100,000 Daltons. The semi-solid matrix in which the islets are embedded and suspended is formed of an appropriate supporting material such as alginate or agar.
