A method and an apparatus according to an embodiment of the invention includes a reflector and an optical fiber end portion disposed within a capillary for use in side-firing optical fibers. The reflector surface can be coated with a multilayer dielectric coating to increase the amount of side-fired laser energy. An outer member or cap can be used to protect the capillary when being inserted through a catheter or endoscope. The endoscope is then at least partially inserted into a patient's body to provide laser-based medical treatment. Multiple grooves can be defined on an outer surface of the optical fiber buffer layer to increase the surface area and improve the mechanical strength of the coupling between the optical fiber and the capillary. In some embodiments, the outer member or cap can also be coupled to the grooved surface portion of the optical fiber buffer layer.

Side-firing laser fiber with glass fused reflector and capillary and related methods

A method and an apparatus according to an embodiment includes a distal end portion of an optical fiber core having a multilayer dielectric coating. For side-firing optical fibers, the coating can be disposed on an angled surface at the core distal end to produce total internal reflection of laser energy at the angled surface. The coating can also be disposed on an outer surface of the distal end portion of the core. The coating and the angled surface can be collectively configured to redirect laser energy in a lateral or side-fired direction. For end-firing optical fibers, the coating can be disposed on an outer surface of the distal end portion of the core. The coating and a perpendicular surface at the core distal end can be collectively configured to direct laser energy in a direction substantially parallel to the distal end portion of the optical fiber.

Dielectric coatings for laser fiber and related methods

A method and an apparatus according to an embodiment of the invention includes disposing a cover about a capillary used in a side-firing optical fiber. The cover can be used to protect the capillary when being inserted through an endoscope for medical treatment. In some embodiments, the cover can be a low-profile cover such as a coating made of a light-sensitive polymer or like material. At least a portion of the coating can be removed after insertion by exposing the light-sensitive material to laser energy transmitted from an optical-fiber-core end housed within the capillary. In other embodiments, the cover can be a slideable or moveable low-profile sleeve or metal cover. During insertion, the sleeve or metal cover is positioned over the capillary. After insertion, the sleeve or metal cover is retracted to expose the area to be treated to side-fired laser energy transmitted from the capillary.

The present invention provides devices and methods for associating an implantable sling with a delivery device for delivering the sling to an anatomical location in a patient.

Systems and methods relating to associating a medical implant with a delivery device

A method and an apparatus according to an embodiment includes a distal end portion of an optical fiber disposed inside a lumen defined along a curved path within a capillary. The distal end surface of the optical fiber can be substantially flush with a portion of an outside surface of the capillary that defines a transmissive portion. The distal end portion of the optical fiber and the curved path can be collectively configured to direct laser energy through the transmissive portion in a lateral or side-fired direction that is offset from a longitudinal axis or centerline of the capillary. In some embodiments, more than one optical fiber can be disposed along the curved path. In other embodiments, more than one curved path can be defined within the capillary such that a distal end portion of an optical fiber can be disposed along each of the curved paths.

A rectal thermal monitor for transrectal prostate temperature measurement includes a handle arranged in a proximal end portion of the monitor for gripping by a user, an elongate shaft extending from the handle, and an expandable distal probe portion arranged on a distal end of the shaft. The distal probe portion is arranged at a position opposite the handle portion, and is shaped to facilitate insertion through an anal sphincter and into a rectum of a patient. A cover element, is provided for covering at least a portion of the distal probe portion, and is made from a resilient material. A temperature sensing element is arranged within the distal probe portion, beneath the cover element, and is adapted and configured to sense a temperature of the prostate of the patient through the rectum wall of the patient. Further, and actuator can be provided to actuate the expandable distal probe portion, to increase a diameter thereof.
