Embodiment Construction

[0039] The devices and methods described herein generally involve an optical fiber configured to treat a target treatment area of ​​a patient's body. Specifically, when the optical fiber is set in the endoscope, the optical fiber can be used to transmit laser energy from the laser source to the target treatment area. One end (the proximal part) of the optical fiber can be coupled to the laser source, and the other end (the distal part) of the optical fiber can be inserted into the patient to provide laser treatment. The optical fiber may include, for example, a fiber core, one or more cladding layers provided around the fiber core, a buffer layer provided around the cladding layer, and a jacket layer (arranged around the buffer layer). In some embodiments, the buffer layer may be referred to as a cladding layer. The jacket layer can also be referred to as a jacket or jacket coating, and the buffer layer can be referred to as a buffer coating.

Abstract

An apparatus includes an optical fiber extending from a proximal end to a distal end. The optical fiber may include a cladding layer circumferentially disposed about a core layer and a substantially spherically shaped portion at the distal end. The apparatus may also include a first coating circumferentially disposed on a first length of the cladding layer, and a second coating circumferentially disposed on a second length of the cladding layer. The second length may extend distally from a region proximate the distal end of the first coating.

Description

[0001] This application relates to and claims the priority of the US provisional patent application serial number 61 / 262,395 filed on November 18, 2009, which is incorporated herein by reference in its entirety. Technical field [0002] The embodiments generally relate to medical equipment, and in particular, to a distal end portion of an optical fiber having a substantially spherical shape. Background technique [0003] During a ureteroscopy operation, a medical practitioner can insert an endoscope (also called a ureteroscope) into the patient's urinary tract, for example, to locate undesirable objects such as kidney stones or bladder stones through a guide wire. Once the stone is found, the optical fiber can be introduced into the working channel of the endoscope and advance in the working channel until the optical fiber touches or is in close proximity to the stone. Electromagnetic radiation energy from, for example, a holmium (Ho) laser is directed to the stone through an opti...
