Detailed Description

Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Ranges can be expressed herein as from "about" one particular value, and/or to "about" another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

Directional terms used herein, such as upper, lower, right, left, front, rear, top, bottom, vertical, horizontal, are made with reference to the drawings as drawn, and are not meant to imply absolute orientations.

Unless expressly stated otherwise, it is in no way intended that any method described herein be construed as requiring that its steps be performed in a specific order, nor that any apparatus require a specific orientation. Thus, where a method claim does not actually recite an order to be followed by its steps or any apparatus claim does not actually recite an order or direction to individual components, or it is not otherwise specifically stated in the claims or descriptions that the steps are to be limited to a specific order or direction to components of an apparatus, it is no way intended that an order or direction be inferred, in any respect. This applies to any possible non-expressive basis for interpretation, including: logical issues regarding step arrangement, operational flow, component order, or component orientation; simple meanings derived from grammatical organization or punctuation; the number or type of embodiments described in the specification.

As used herein, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a" component includes aspects having two or more such components, unless the context clearly dictates otherwise.

As used herein, the term "press fit" includes any coupling of elements that couples when one or more contact portions of the elements are pushed together. In some embodiments, the press fit comprises a friction fit, wherein the two elements are held together at least partially through friction between the mating surfaces. In other embodiments, the press fit comprises an interference fit in which the coupling elements interfere with each other (e.g., a solid or hollow shaft slightly larger than the bore into which it is inserted, such as male and female luers). In other embodiments, the press fit may include a resilient engagement (e.g., a pin inserted into a hole in a resilient sleeve, the inner diameter of which is smaller than the diameter of the pin).

As used herein, the term "stud" includes any protrusion on the surface of an element. The stud may be solid or hollow and may, for example, comprise a bump, projection, boss or pin. The studs may have any suitable shape including, for example, circular, square, rectangular, trapezoidal, oval, or any combination thereof. In some embodiments, the studs may be formed within physical tolerances that allow one or more studs on the surface to be coupled to another element.
