Patent number: 7264609Abstract: A self-retaining catheter that eliminates the problem of residual urine and also of bladder wall irritation caused by continuous contact with a spherical retention balloon which does not rely on a stylet for placement. The system may use an internal control wire that reversibly foreshortens the proximal end of the catheter thus radially displacing longitudinal strips defined in the proximal catheter to form retention wings. Alternatively, a balloon situated between the longitudinal strips is inflated to force open the retention wings once inside the urinary bladder. Radial displacement of the retention wings widens the spaces between the longitudinal strips, these spaces constituting the drainage apertures which permit complete emptying of the urinary bladder. The radially displaced retention wings abut the bladder wall in a non-continuous manner thereby reducing the area of bladder-catheter contact and further reducing bladder wall irritation.Type: GrantFiled: November 6, 2003Date of Patent: September 4, 2007Inventors: Said I. Hakky, A-Hamid Hakki

Patent number: 6458098Abstract: A vascular therapy device is used for treatment, such as injecting or applying medicine, to a lumen or body cavity without surgical treatment. The vascular therapy device includes an elongated shaft, an inflatable balloon attached to a side portion of a distal end portion of the shaft, a first path provided in the shaft and communicating with an inside of the balloon to inflate and deflate the balloon, and a second path provided inside the shaft and extending from a proximal end portion to the distal end portion of the shaft. The second path has an outlet at the distal end portion. When the balloon is inflated, a part of the distal end portion is biased to contact a wall where the shaft is inserted. Thus, when the balloon is inflated, the outlet faces and substantially contacts the wall to thereby provide a treatment through the second path and outlet.Type: GrantFiled: March 17, 2000Date of Patent: October 1, 2002Inventor: Nozomu Kanesaka
