Publication number: 20050165383Abstract: 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.Type: ApplicationFiled: January 7, 2005Publication date: July 28, 2005Inventors: Uzi Eshel, Jacob Lazarovitz, Richard Klein

Publication number: 20050054994Abstract: Methods, systems, and computer program products for obtaining a sample in vivo and/or treating a subject include positioning an elongated transurethral catheter in the prostatic urethra of a subject, the catheter having a bladder anchoring balloon, at least one biosample entry port disposed axially away from the bladder anchoring balloon, and an axially extending biosample flow channel in fluid communication with the biosample entry port held internally in the catheter. The anchoring balloon is inflated to position the catheter so that the fluid entry port is proximate the prostatic urethra of the subject and prostatic fluid is suctioned from the prostatic urethra into the biosample entry port and into the biosample flow channel. The catheter can include a thermal treatment balloon and/or dilatation balloon and the suctioned sample can be obtained concurrently with, during, or proximate in time to the applied treatment.Type: ApplicationFiled: April 19, 2004Publication date: March 10, 2005Inventors: Iulian Cioanta, Richard Klein, Jacob Lazarovitz

Patent number: 6849063Abstract: 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.Type: GrantFiled: November 5, 1999Date of Patent: February 1, 2005Assignee: WIT IP CorporationInventors: Uzi Eshel, J.

Publication number: 20040236365Abstract: Medical devices that are configured for insertion into a body lumen, such as the male urethra, are provided with one or more inflatable balloons having elastic sleeves, wherein each elastic sleeve is adapted to inflate in response to inflation of a respective balloon, and to deflate in response to deflation of the respective balloon. When a balloon is in a deflated condition a respective elastic sleeve exerts a circumferentially compressive force against the balloon to cause a smooth, reduced cross-sectional profile of the balloon along an axial extent thereof. This smooth, reduced cross-sectional profile can facilitate passage of the medical device through a body lumen during both insertion and extraction of the medical device. A thin layer of fluid may be disposed between a treatment balloon and a respective elastic sleeve to facilitate heat transfer from a treatment balloon to a surrounding elastic sleeve or to administer a therapeutic agent to localized tissue.Type: ApplicationFiled: June 29, 2004Publication date: November 25, 2004Applicant: WIT IP CorporationInventors: Iulian Cioanta, Jacob Lazarovitz

Publication number: 20040230188Abstract: Flexible treatment catheters are configured to be inserted into a body lumen or cavity to deliver heated fluid through at least one fluid lumen therein to thermally treat or ablate a targeted site in a biological subject. The flexible treatment catheters can include improved thermally insulated regions comprising a mixture formed of liquid elastomeric (such as a polyurethane) mixture (which transitions to a solid state) and miniaturized hollow plastic bodies positioned between the outer wall of the treatment catheter and the fluid lumen. The thermally insulated region is configured such that, measured ex vivo, the treatment catheter can present a maximum temperature of below about 45° C. on the external surface of the outer wall of the treatment catheter when the treatment catheter circulates fluid having an inlet temperature of above or between about 60°-62° C.Type: ApplicationFiled: May 12, 2003Publication date: November 18, 2004Inventors: Iulian Cioanta, Richard Barry Klein, Jacob Lazarovitz
