1. A connector comprising:
- a tubular body having an exterior surface extending between a proximal end and an opposing distal end, the proximal end terminating at a proximal end face and the opposing distal end terminating at a distal end face, the tubular body having an interior surface bounding a linear passage extending therethrough between the proximal end face and the opposing distal end face, the passage having a central longitudinal axis extending along the length thereof;
a membrane secured directly to the distal end face of the tubular body so as to seal the passage closed thereat, the membrane being disposed in a plane that orthogonally intersects with the central longitudinal axis of the tubular body, the membrane and the body being configured so that when an energy is applied to the membrane and the body, at least a portion of the membrane exposed to the energy melts to form an opening therein and at least a portion of the body exposed to the energy does not melt; and
an alignment stem projecting from the distal end of the tubular body so that at least a portion of the alignment stem is disposed distal of the membrane.

Abstract
A system for forming a fluid connection includes a first connector and a second connector. Both connectors include a tubular body having a membrane mounted on a distal end thereof. A support member facilitates the coupling of the connectors together so that the membranes are abutted together. Radiant energy is applied to the abutted membranes so as to first sterilize the membranes and then melt the membranes so that a passage is formed therethrough.

12. A system for forming a fluid connection, the system comprising:
-
a first connector comprising; tubular first body having a linear first passage extending therethrough between a proximal end and an opposing distal end, the first passage having a central first longitudinal axis extending along the length thereof; a first membrane sealing the first passage closed at the distal end of the first body; a first alignment slot formed on the distal end of the tubular first body; and a first alignment stem projecting from the distal end of the tubular first body; a second connector comprising; tubular second body having a linear second passage extending therethrough between a proximal end and an opposing distal end, the second passage having a central second longitudinal axis extending along the length thereof; and a second membrane sealing the second passage closed at the distal end of the second body, the first membrane and the second membrane being adapted to melt under the application of energy; a second alignment slot formed on the distal end of the tubular second body; and a second alignment stem projecting from the distal end of the tubular second body; and the distal end of the first body being coupled to the distal end of the second body so that the first alignment stem is received within the second alignment slot, the second alignment stem is received within the first alignment slot, the first longitudinal axis is aligned with the second longitudinal axis, and the first membrane is disposed against or adjacent to the second membrane; and a support member coupling the distal end of the first body to the distal end of the second body, the support member being separable from the first connector and the second connector. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
