Design patterns are algorithms for object-oriented programming. Normally we think of an algorithm as a list of instructions to be followed to perform a task. In procedural programming, it's easy to point to a subroutine and say, "This is a sorting algorithm."
It's harder to point to a collection of a dozen objects and say they are an "algorithm" to do something. "Design pattern" is an attempt to capture the same concept that "algorithm" does for procedural programming.
The book
Ready-to-Run Visual Basic Algorithms, Second Edition
includes a chapter on object-oriented paradigms that are design patterns. It also includes a host of more traditional procedural algorithms.

The book
Design Patterns
by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides explains a variety of design patterns in C++. While the code examples are in C++, the ideas are easy to translate into Visual Basic.
