What is claimed is:
1. A vertical spacer for use in spacing adjacent glass blocks, comprising:
(a) two planar pieces each of said planar pieces having a first edge and a second edge, said first edge opposite said second edge;
(b) said first edges joined together to provide a fixed distance between two adjacent glass blocks; and
(c) said second edges joined together to provide a variable distance between said two adjacent glass blocks.
2. The vertical spacer according to claim 1, wherein said second edge includes:
(a) one or more ridges; and
(b) one or more troughs said one or more troughs operative to engage said one or more ridges.
3. The vertical spacer according to claim 1, wherein said vertical spacer is comprised of one of: PVC, plastic or a combination thereof.
4. The vertical spacer according to claim 1, wherein said vertical spacer is substantially equal in height to said adjacent glass blocks.
5. The vertical spacer according to claim 1, wherein said fixed distance is of an inch.
6. The vertical spacer according to claim 1, wherein said adjustable distance is adjustable from of an inch to of an inch to of an inch.
7. A connector for connecting two horizontally disposed spacers across a vertical gap in a wall of glass blocks, comprising:
(a) a first connector portion coupled to an end of a first spacer; and
(b) a second connector portion coupled to an end of a second spacer whose end is opposed to the end of said first spacer, said second connector portion rotatably coupled to said first connector portion.
8. The connector according to claim 7, wherein said first connector portion is coupled to said first spacer by one or more first prongs and said second connector portion is coupled to said second spacer by one or more second prongs.
9. The connector according to claim 8, wherein said first and second prongs are each two in number.
10. The connector according to claim 8, wherein said first connector portion and said second connector portion are identically shaped.
11. The connector according to claim 8, wherein said first and second prongs include barbs.
12. The connector according to claim 8, wherein said connector is comprised of one of: PVC, plastic and a combination thereof.
13. A method of forming a curved glass block wall from substantially rectangular glass blocks, comprising:
a) adjusting an adjustable vertical spacer to define a desired curvature in said curved glass block wall;
b) positioning said adjustable vertical spacer between adjacent vertical sides of adjacent glass blocks;
c) positioning horizontal spacers between adjacent horizontal sides of adjacent glass blocks; and
d) connecting adjacent ones of said horizontal spacers with transversely adjustable horizontal connectors.
14. The method according to claim 13, wherein said vertical spacers are substantially equal in height to said glass blocks.
15. The method according to claim 13, wherein said horizontal spacers are substantially equal in length to said glass blocks.
16. The method according to claim 13, wherein said transversely adjustable horizontal connectors are further capable of lateral adjustment within said horizontal spacers.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. Scoring or cutting balloon catheter carrying at least on a portion of its surface the oxidation-insensitive drug paclitaxel and the lipophilic antioxidant propyl gallate at a ratio of 3-100% by weight of the propyl gallate in relation to 100% by weight of the paclitaxel.
2. Scoring or cutting balloon catheter according to claim 1, wherein the propyl gallate is contained at a ratio of 5-100% by weight, preferably at a ratio of 10-100% by weight, more preferred at a ratio of 20-100% by weight, and even more preferred at a ratio of 50-100% by weight in relation to 100% by weight of the paclitaxel.
3. Scoring or cutting balloon catheter according to claim 1, wherein the paclitaxel is more lipophilic than the propyl gallate.
4. Scoring or cutting balloon catheter according to claim 1, wherein the propyl gallate load is up to 10 gmm2 of coated catheter surface.
5. Scoring or cutting balloon catheter according claim 1, which has been polymer-free coated with paclitaxel and propyl gallate both together dissolved in tetrahydrofuran or a mixture of solvents containing more than 25% (vv) tetrahydrofuran or each separately dissolved optionally selecting a different solvent for the propyl gallate.
6. Scoring or cutting balloon catheter according to claim 1, which has been polymer-free coated with paclitaxel and propyl gallate both together dissolved in acetone or a mixture of solvents containing more than 25% OM acetone or each separately dissolved optionally selecting a different solvent for the propyl gallate.
7. Scoring or cutting balloon catheter according to claim 1, which has been polymer-free sequentially coated with paclitaxel and propyl gallate in a way that the paclitaxel and the propyl gallate are not homogeneously mixed.
8. The balloon catheter of claim 1 wherein the paclitaxel is polymer-free.
9. The balloon catheter of claim 1 wherein said catheter is a scoring balloon catheter.
10. The balloon catheter of claim 1 wherein said catheter is a cutting balloon catheter.
