    摘要： 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.

    摘要： According to an aspect of the present invention, a medical device is provided, which comprises the following: (a) a hollow elongate body (e.g., an elongate cylinder, such as a needle) having distal and proximal ends; and (b) a rotatable member comprising a tissue morselizer and an elongate shaft (e.g., an auger-like tissue-drilling bit). The device (i) advance material (e.g., morselated tissue) toward the proximal end of the hollow elongate body when the shaft is rotated in a first direction, and (ii) advance material (e.g., a therapeutic agent and/or a bulking agent) toward the distal end of the hollow elongate body when the shaft is rotated in a second direction that is opposite the first direction. The invention also provides a method of treatment for morselizing and removing tissue from within the patient and creating a void within the patient and introducing a therapeutic agent and/or a bulking agent into the void.

    摘要： A prostate therapy system is provided that may include any of a number of features. One feature of the prostate therapy system is that it can access a prostate lobe from the urethra. Another feature of the prostate therapy system is that it can deliver condensable vapor into the prostate to ablate the prostate tissue. Another feature of the prostate therapy system is that it can aspirate tissue from the prostate. Yet another feature of the prostate therapy system is that it can rotate during delivery of vapor and aspiration of tissue. Methods associated with use of the prostate therapy system are also covered.

    摘要： An electrical ablation apparatus comprises first and second electrodes. Each electrode comprises a first end configured to couple an energy source and a second end configured to couple to a tissue treatment region. An energy source is coupled to the first and second electrodes. The energy source is configured to deliver a first series of electrical pulses sufficient to induce cell necrosis by irreversible electroporation and a second series of electrical pulses sufficient to induce cell necrosis by thermal heating, through at least one of the first and second electrodes. The first series of electrical pulses is characterized by a first amplitude, a first pulse length, and a first frequency. The second series of electrical pulses is characterized by a second amplitude, a second pulse length, and a second frequency.
