A device and related methods of production are provided for a medical device. In an embodiment, the medical device includes a sheath, a cap disposed at a distal end of the sheath, and an electromagnetic radiation source. The cap may include a material that is substantially transparent. The electromagnetic radiation source may be positioned proximally from a distal-most end of the cap.
Field of the Invention
 Embodiments relate generally to medical devices and procedures, and,
in particular, to endoscopic devices and procedures for using such devices.
Background of the Invention
 A variety of different known types of endoscopes may be used in many
medical, dental, and veterinary applications. Some known endoscopes include
optical components such as a light source, an image sensor, and/or lenses, within a
distal end portion of the endoscope. For example, it is often desirable to provide
light focusing capabilities within the endoscope through the use of lenses or other
optical components coupled to the endoscope distally, near a light source (e.g., a
distal end of an optical fiber, a light emitting diode (LED)), or near an image sensor
(e.g., charge-coupled device (CCD)). Such optical components are typically coupled
to a structure at the distal end portion of the endoscope. For example, in some
known endoscopes, a lens may be glued to a distal end portion of an optical fiber
that may be used with the endoscopes. In such a case, the lens may not be
precisely positioned on the optical fiber because the glue adhering the lens to the
endoscope may not have been uniformly applied, or the lens may have moved
relative to the position of the optical fiber before the glue has completely dried. In
addition, optical components may become loose or detached from the endoscope
during use. This may result in, for example, reduced quality of images gathered
during an endoscopic procedure and/or one or more optical components becoming
detached from the endoscope and disposed within the patient's body. Moreover,
some known endoscopes are designed for multiple use and require sterilization prior
to re-use. The sterilization procedure may be expensive and may subject the
delicate endoscopic optical components (e.g., lenses) to a harsh environment that
may crack or otherwise damage the endoscopic optical components, rendering the
 Thus, a need exists for an improved endoscope and endoscopic tip
that may, for example, provide more robust light focusing capabilities.
SUMMARY OF THE INVENTION
 Embodiments of the invention provide a medical device and procedure
for producing the medical device.
 In accordance with an aspect of the present disclosure, a medical
device may include a sheath having a proximal end and a distal end. The medical
device may further include a cap disposed at the distal end of the sheath such that
the cap has a distal-most end. The cap may includes a material that is substantially
transparent. The medical device may further include an electromagnetic radiation
source. The electromagnetic radiation source may be positioned proximally from the
distal-most end of the cap.
