PROTECTING ALGAE FROM BODY FLUIDS
First Claim
1. Apparatus for implantation into a body of a subject, comprising:
- isolated functional cells;
at least one first semi-permeable barrier having associated therewith a first molecular weight cutoff, disposed with respect to the functional cells so as to protect the functional cells from components disposed within a body fluid of the subject having molecular weights higher than the first cutoff;
photosynthetic elements, disposed with respect to the functional cells so as to provide oxygen thereto; and
at least one second semi-permeable barrier having associated therewith a second molecular weight cutoff that is lower than the first cutoff, the second barrier disposed with respect to the photosynthetic elements so as to protect the photosynthetic elements from components disposed within the body fluid of the subject having molecular weights higher than the second cutoff.

Abstract
Apparatus (20) is provided for implantation into a body of a subject, including isolated functional cells (28). At least one first barrier (22) having a first molecular weight cutoff is disposed with respect to the functional cells so as to protect the functional cells from components disposed within body fluid of the subject having molecular weights higher than the first cutoff. Photosynthetic elements (26) are disposed with respect to the functional cells so as to provide oxygen thereto. At least one second barrier (24) has a second molecular weight cutoff that is lower than the first cutoff. The second barrier is disposed with respect to the photosynthetic elements so as to protect the photosynthetic elements from components disposed within the body fluid of the subject having molecular weights higher than the second cutoff. Other embodiments are also described.

33. A method, comprising:
-
protecting isolated functional cells from a first set of components disposed within body fluid of a subject by using at least one first semi-permeable barrier having associated therewith a first molecular weight cutoff; protecting photosynthetic elements from a second set of components disposed within the body fluid of the subject by using at least one second semi-permeable barrier having associated therewith a second molecular weight cutoff, the first molecular weight cutoff being lower than the first cutoff; and implanting within the body of the subject the first semi-permeable barrier, the second semi-permeable barrier, the functional cells, and the photosynthetic elements. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
