Tissue is composed of cells that have specialized, such as prostate cells which have specialized to form prostatic tissue. Prostatic tissue is specialized to make the prostate gland, an organ which is located directly under the bladder and in front of the rectum.

Dynamic heating method and radio frequency thermal treatment

A method and system for the delivery of radiofrequency energy to the tissue, particularly, the prostate, to alleviate the symptoms of BPH is disclosed. The system incorporates a bipolar or multipolar electrode array to create an electric field where the heat created is confined solely to a specific volume of the prostate gland and therefore the heated tissue is defined only by the electrode geometry. The bipolar electrode array provides a variety of three dimensional, symmetric heating patterns within the prostatic tissue depending on the relative electrode lengths and angular separation. The system provides precision tissue temperature and impedance measurements thereby enabling the surgeon to accurately predict heating pattern performance and tissue response to RF heating.

Apparatus and method for thermal treatment of body tissue

An apparatus and method for the thermal treatment of tissue, e.g., prostatic tissue, with RF energy is disclosed. The apparatus includes a handle dimensioned to be grasped with a single hand of a surgeon, an elongated portion extending distally from the handle and defining a longitudinal axis, at least one electrode extending within the elongated portion and movable between a non-deployed position and a fully deployed position, and a trigger mechanism associated with the handle and having a trigger operatively connected to the one electrode. The trigger is movable to selectively and incrementally move the one electrode between the non-deployed position and the fully deployed position. A ratchet mechanism permits movement of the trigger in one direction corresponding to movement of the one electrode toward the fully deployed position while preventing movement of the trigger in a second direction. The elongated portion of the apparatus may be rotatable about the longitudinal axis to reposition the one electrode.

Medicament for treating prostate diseases

A medicament based on antibodies contains an activated form of ultra-low doses of monoclonal, polyclonal, or natural antibodies to the prostate-specific antigen, the activated form being prepared by multiple consecutive dilutions and exposure to external factors, preferably according to homeopathic technology. In order to obtain the antibodies, the prostate-specific antigen isolated from the prostatic tissues of cattle or prepared synthetically is employed; a mixture of various, mostly centesimal, homeopathic dilutions is used. The method of treating diseases of the urogenital sphere consists in using activated forms of ultra-low doses of antibodies to prostate-specific antigen prepared by multiple consecutive dilutions and exposure to external factors.

Peri-vascular tissue ablation catheter with support structures

An intravascular catheter for peri-vascular and / or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand with open ends around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and / or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system also includes means to limit and / or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The preferred embodiment of the catheter includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.

Methods for predicting prostate cancer recurrence

The present invention relates to the identification of four cytokine biomarkers in prostatic tissue that exhibit differential expression following prostatectomy that, in combination at least one other factor, are able to reliably predict the development of biochemical recurrence following surgery. This marker combination improves the risk stratification of patients after primary local treatment for localized prostate cancer.

Energy application with inflatable annular lens

Apparatus and methods for ablating tissue surrounding a tubular anatomical structure such as the wall of a blood vessel or prostatic tissue surrounding the urethra. The apparatus includes an ultrasonic emitter such as a cylindrical emitter and an inflatable annular lens balloon surrounding the ultrasonic emitter. The lens balloon is inflated with a liquid having acoustic velocity different than that of the surrounding medium, so as to form an annular refracting surface. The acoustic energy from the emitter is focused into an annular focal region.

Second, third and fourth near-infrared spectral windows for deep optical imaging of tissue with less scattering

Light at wavelengths in the near-infrared (NIR) region in the second NIR spectral window from 1,100 nm to 1,350 nm and a new spectral window from 1,600 nm to 1,870 nm, known as the third NIR optical window, and fourth at 2200 cm−1 are disclosed. Optical attenuation from thin tissue slices of normal and malignant breast and prostate tissue, and pig brain were measured in the spectral range from 400 nm to 2,500 nm. Optical images of chicken tissue overlying three black wires were also obtained using the second and third spectral windows. Due to a reduction in scattering and minimal absorption, longer attenuation and clearer images can be seen in the second, third and fourth NIR windows compared to the conventional first NIR window. The second and third spectral windows will have uses in microscope imaging arteries, bones, breast, cells, cracks, teeth, and blood due to less scattering of light.

Microwave medical treatment apparatus and method

Methods, simulations, and apparatus are provided that may be utilized for medical treatments which are especially suitable for treatment of benign prostatic hyperplasia (BPH). In a preferred embodiment, a plurality of separate microwave antennas are utilized to heat prostatic tissue to promote necrosing of the prostatic tissue that relieves the pressure of the prostatic tissue against the urethra as the body reabsorbs the necrosed or dead tissue. By utilizing constructive and destructive interference of the microwave transmission, the energy can be deposited on the tissues to be necrosed while protecting other tissues such as the urethra. Saline injections to alter the conductivity of the tissues may also be used to further focus the energy deposits. A computer simulation is provided that can be used to predict the resulting temperature profile produced in the prostatic tissue. By changing the various control features of one or more catheters and the methods of applying microwave energy, a temperature profile can be predicted and produced that is similar to the temperature profile desired for the particular patient.

Computer program for microwave antenna

A method, simulation, and apparatus are provided that are highly suitable for treatment of benign prostatic hyperplasia (BPH). A catheter is disclosed that includes a small diameter disk loaded monopole antenna surrounded by fusion material having a high heat of fusion and a melting point preferably at or near body temperature. Microwaves from the antenna heat prostatic tissue to promote necrosing of the prostatic tissue that relieves the pressure of the prostatic tissue against the urethra as the body reabsorbs the necrosed or dead tissue. The fusion material keeps the urethra cool by means of the heat of fusion of the fusion material. This prevents damage to the urethra while the prostatic tissue is necrosed. A computer simulation is provided that can be used to predict the resulting temperature profile produced in the prostatic tissue. By changing the various control features of the catheter and method of applying microwave energy a temperature profile can be predicted and produced that is similar to the temperature profile desired for the particular patient.
