Surgical mesh

Surgical mesh is a loosely woven sheet which is used as either a permanent or temporary support for organs and other tissues during surgery. The meshes are available in both inorganic and biological materials, and are used in a variety of surgeries. Though hernia repair surgery is the most common application, they can also be used for reconstructive work, like in pelvic organ prolapse.

Permanent meshes remain in the body, whereas temporary ones dissolve over time. For example, TIGR Matrix test mesh was fully dissolved after three years in a recent trial on sheep. Some meshes combine permanent and temporary meshes such as Vipro, a product combining re-absorbable vipryl, made from polyglycolic acid, and prolene, a non-reabsorbable polypropylene.

Mesh

A mesh is a barrier made of connected strands of metal, fiber, or other flexible/ductile materials. A mesh is similar to a web or a net in that it has many attached or woven strands.

Types of mesh

Partition of an interval

In mathematics, a partition of an interval [a, b] on the real line is a finite sequence x = ( x_i ) of real numbers such that

In other terms, a partition of a compact interval I is a strictly increasing sequence of numbers (belonging to the interval I itself) starting from the initial point of I and arriving at the final point of I.

Every interval of the form [x_i, x_i+1] is referred to as a sub-interval of the partition x.

Refinement of a partition

Another partition of the given interval, Q, is defined as a refinement of the partition, P, when it contains all the points of P and possibly some other points as well; the partition Q is said to be “finer” than P. Given two partitions, P and Q, one can always form their common refinement, denoted P ∨ Q, which consists of all the points of P and Q, re-numbered in order.

Norm of a partition

The norm (or mesh) of the partition

is the length of the longest of these subintervals, that is

Applications

Partitions are used in the theory of the Riemann integral, the Riemann–Stieltjes integral and the regulated integral. Specifically, as finer partitions of a given interval are considered, their mesh approaches zero and the Riemann sum based on a given partition approaches the Riemann integral.
