US 2025/0135178 A1 · EXTENSION SYSTEM FOR COUPLING TUBULAR DEVICES

Abstract

An extension system for connecting or coupling a guidewire, primary or initial wire to an extension or secondary wire, a method of coupling elongate devices (40,41,42,43) and a method of using an extension system. The extension system is formed by the connection of devices to extension tubes or wires. In this way, connecting or coupling a guidewire, primary or initial wire to an extension or secondary wire may be done during or before a medical procedure. The resulting coupling from the extension system allows independent relative movement between inner and outer components of an endoluminal device such as a guiding catheter, endoscope, medical instrument or guidewire. In an assembled state, multiple concentric wires and tubular components can be locked and secured by a simple single movement, followed by a relative rotation, translation or both in order to create a mechanical strength between them that resembles such strength as if there was no connection at all. The extension system may also be used for procedures other than medical procedures.

An extension system for coupling elongate devices, the extension system comprising:

a first set of elongate members each defining a coupling section formed at a substantial end thereof;
and
a second set of elongate members defining a tubular structure that is sized and shaped such that each of the corresponding elongate members of the first set may be placed concentrically therein with axial freedom of movement therebetween, wherein each of the elongate members of the second set defines a coupling section formed at a substantial end thereof, the first and second sets configured such that a stabilized connection of the extension system is formed by taking the steps of:
(i) placement of one of the elongate members of the first set into a corresponding one of the elongate members of the second set such that their coupling sections are rotationally and axially aligned;
(ii) placement of the other of the elongate members of the first set into a corresponding other one of the elongate members of the second set such that their coupling sections are rotationally and axially aligned;
(iii) simultaneous placement of the coupling sections of both the first and second set into registration with each other so that their coupling sections form a first set lock and a second set lock;
and
(iv) displacement of the first and second set locks relative to one another.
