A method of treating a bladder condition is provided. The method is effected by circulating a volume of heated fluid through a urinary bladder of a subject in need and gradually increasing the volume of fluid up to a predetermined fluid volume and or pressure.

Method and system for treating bladder conditions

A method, device, and system for treatment of urinary tract disorders is provided. The device includes a catheter having multiple lumens for insertion into a urinary bladder and for providing fluid flow within the bladder and within the fluid reservoir within the urethra. The device further includes an anchor to be placed within the bladder. A port hub having multiple ports is connected at a proximal end of the catheter. A method of treatment includes providing heated fluid to a urinary bladder and to a fluid reservoir for insertion into an adjacent organ such as the urethra. Simultaneous treatment or separate treatment may be done. Optionally, a medicated solution may be added to the heated fluid. Additionally, pressure may be adjusted so as to optimize the therapeutic effect.

System and method for treating urinary tract disorders

An indwelling catheter for insertion into a patient's urinary tract is provided that includes first and second tubular members that enable drainage of physiological fluids. An inflatable balloon is attached to the second tubular member. The first and second tubular members are interconnected by a connecting tube forming a gap between the first and second tubular members. The connecting tube is in fluid communication with the balloon to enable the balloon to be inflated via the connecting tube. When the balloon is anchored within the urinary bladder the second tubular member is located within the prostatic urethra with one end in close proximity to the sphincter and the other end protruding into the urinary bladder. The first tubular member is located within the penile urethra with one end in close proximity to the sphincter so that the connecting tube traverses the sphincter permitting voluntary control of the sphincter.

Urethral catheter and guide

A temperature-setting device for providing a predetermined temperature to a quantity of fluid circulating therethrough, a thermal treatment apparatus including such device for selectively treating a targeted tissue adjacent a subject's body cavity, and techniques using such thermal treatment apparatus are provided. The temperature-setting device comprises: an electrically conducting tubular element, a housing element for receiving the tubular element; and a transformer electrically connectable to the housing element. The tubular element functions as a resistor and heats the fluid circulating therethrough. Alternatively, the housing element comprises a thermal conducting member disposed within a bath of a cooling substance, the thermal conducting member having a recess for receiving the tubular element. The tubular element may alternately be placed in a housing element functioning as a heater and a housing element functioning as a cooler, thereby alternately heating or cooling the fluid circulating therethrough. The thermal treatment apparatus comprises: a temperature-setting device according to the present invention; a catheter insertable into a subject's body cavity, the catheter including a thermal treating section for thermally treating a targeted tissue; a pump; thermal sensor assemblies; and an air trapping element.

Thermal treatment apparatus

A catheter for insertion into a patient's urethra is provided, comprising: (a) first and second tubular members having such a diameter for enabling drainage of physiological fluids therethrough, the first and second tubular members being interconnected by means of a connecting tube of substantially smaller diameter; (b) an inflatable balloon attached to the second tubular member, the inflatable balloon being in fluid communication with the connecting tube. The inflatable balloon is inserted to the patient's urinary bladder so as to locate the second tubular member substantially within the patient's prostatic urethra such that the connecting tube is held by the patient's sphincter. Further according to the present invention there is provided a guiding element for insertion through the catheter, including: (a) a substantially elongated tubular member having a hollow, the elongated tubular member having a closed end for insertion through the patient's urethra and an open end for connection to an external inflating element; (b) an inflatable balloon attached to the elongated tubular member, the inflatable balloon being in fluid communication with the hollow of the tubular element, the inflatable balloon for inflation against the catheter so as to effectively fix the guiding element to the catheter.

Internal catheter

Thermal treatment apparatus for thermally treating selected tissues of a subject located in or near a body cavity, includes a catheter insertable into the subject's body cavity and having a proximal end formed with an inflatable anchoring section for anchoring the catheter in the body cavity, a distal end to be located externally of the body cavity, and an inflatable heating section adjacent the proximal end to be located near the tissue to be heated. The catheter is formed with passageways extending from the distal end to the inflatable heating section for circulating heated fluid through the inflatable heating section but not through the inflatable anchoring section, and a further passageway from the distal end to the inflatable anchoring section for inflating the inflatable anchoring section with a non-heated fluid. The inflatable heating section and the tissue in its proximity may thus be heated to a desired high temperature without correspondingly heating the inflatable anchoring section and the tissue in its proximity.

A technique for localized thermal therapeutic treatment of mammals comprising the steps of inserting a catheter through a urethra, the catheter including a first elongate portion including first and second passageways for circulation of a heated fluid and a plurality of sealed elongate enclosures which contain trapped gas and provide thermal insulation surrounding the first and second passageways and a second portion void of insulation extending from the first elongate portion with extensions of the first and second passageways therethrough; and circulating a heated fluid through the first and second passageways to provide desired therapeutic heating of the body tissue surrounding the second portion by thermal dissipation from the surface thereof.

Technique for localized thermal treatment of mammals

An applicator for insertion into a body opening for medical treatment or for diagnostic purposes comprises an elongated jacket for insertion into the body opening, a disposable sleeve received on the jacket, and a balloon integrally formed on the disposable sleeve at one side of the jacket. The balloon is inflatable by a fluid to press the opposite side of the jacket and sleeve laterally against the tissue of the body opening, thereby to fix the position of the jacket within the body opening and to conform the pressed body tissue to the shape of the opposite side of the jacket. The applicator further includes a microwave antenna disposed within the jacket, the jacket further including cooling ducts adjacent its outer surface for circulating a cooling fluid therethrough in order to prevent undue heating of the body tissue in direct contact with the jacket.

Applicator for insertion into a body opening for medical purposes

A catheter for insertion into a body cavity, comprises a tubular shaft formed with a passageway extending longitudinally therethrough closed at one end and open at the opposite end and a probe removably received within the passageway through its open end. The probe includes a temperature sensor for sensing the heat produced by a heating applicator applied to an adjacent area of the body. The heating applicator includes a microwave antenna producing an electromagnetic field for heating the body tissue adjacent to the body cavity, and the sensor including an electromagnetic field detector for detecting the peak of the electromagnetic field produced by the applicator antenna.
