Abstract

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.

METHODS AND APPARATUS RELATED TO A TRANSPARENT ENDOSCOPIC TIP

Field of the Invention

[001] Embodiments relate generally to medical devices and procedures, and,

in particular, to endoscopic devices and procedures for using such devices.

Background of the Invention

[002] 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

endoscope inoperable.

[003] 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

[004] Embodiments of the invention provide a medical device and procedure

for producing the medical device.

[005] 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.

[006] Various embodiments of the invention may include one or more of the

following aspects: an image detector that may be positioned proximal to the d...
