Abstract
A connector and method of medical tubing is disclosed. The connector defines a fluid passageway, and the connector includes a first end, a first intermediate portion, a middle portion, a second intermediate portion, and a second end. The middle portion is located between the first intermediate portion and the second intermediate portion, and the first end is adapted to fit inside a proximal connector-receiving portion, and the second end is adapted to fit inside a distal connector-receiving portion. The connector includes at least a first protrusion and a second protrusion projecting from the connector, wherein a first protrusion is located between the first end and the first intermediate portion, and the second protrusion is located between the second intermediate portion and the second end. The connector includes a first tubular strain relief having an extending first portion that extends past the first end of the connector and is adapted to fit over a proximal connection section, and a second tubular strain relief having an extending second portion that extends past the second end of the connector and is adapted to fit over a distal connection section. When the first end of the connector is inserted into a proximal connector-receiving portion a first interlock fit is formed therebetween, and when the second end of the connector is inserted into the distal connector-receiving portion a second interlock fit is formed therebetween, resulting in a fluid tight connection between the proximal connector-receiving portion and the distal connector-receiving portion, and wherein at least the middle portion of the connector is exposed. The middle portion of the connector can include a suture receiving section that can be sutured to tissue of patient.
