Claims18
A medical device comprising a plasticized nylon, wherein the plasticized nylon comprises a nylon and an amide-containing plasticizer selected from a compound having the following structural formulas:
- and combinations thereof;
- wherein:
- each R1, R3, R5, R7, R9, and R11 is independently selected from a C2-C18 linear, branched, or cyclic monovalent aliphatic group, a C5-C12 monovalent aromatic group, and combinations thereof;
- and
- each R2, R4, R6, R8, and R10 is independently selected from a C2-C18 linear, branched, or cyclic divalent aliphatic group, a C5-C12 divalent aromatic group, and combinations thereof.
A medical device comprising a plasticized nylon, wherein the plasticized nylon comprises Nylon-12 and an amide-containing plasticizer having the following structural formula:
- wherein:
- each R1, R3, and R5 is independently selected from a C2-C18 linear, branched, or cyclic alkyl group, a C5-C12 monovalent aromatic group, and combinations thereof;
- and
- each R2 and R4 is independently selected from a C1-C5 linear alkylene group, a C5-C12 divalent aromatic group, and combinations thereof.
A balloon dilatation catheter, comprising:
- a tubular elongated catheter shaft having proximal and distal portions;
- and
- a dilatation balloon disposed on said shaft, wherein the shaft and/or balloon comprises a plasticized nylon, wherein the plasticized nylon comprises Nylon-12 and an amide-containing plasticizer having the following structural formula:
- wherein:
- each R1, R3, and R5 is independently selected from a C2-C18 linear, branched, or cyclic alkyl group, a C5-C12 monovalent aromatic group, and combinations thereof;
- and
- each R2 and R4 is independently selected from a C1-C5 linear alkylene group, a C5-C12 divalent aromatic group, and combinations thereof.
A plasticized nylon comprising nylon and an amide-containing plasticizer selected from a compound having the following structural formulas:
- and combinations thereof;
- wherein:
- each R1, R3, R5, R7, R9, and R11 is independently selected from a C2-C18 linear, branched, or cyclic monovalent aliphatic group, a C5-C12 monovalent aromatic group, and combinations thereof;
- and
- each R2, R4, R6, R8, and R10 is independently selected from a C2-C18 linear, branched, or cyclic divalent aliphatic group, a C5-C12 divalent aromatic group, and combinations thereof.
