The retention balloon of the Foley urinary drainage catheter is replaced by a new self-retaining system. This new self-retaining catheter eliminates the problem of residual urine and also of bladder wall irritation caused by continuous contact with a spherical retention balloon; it also does not rely on a stylet for placement. The new 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, thereby eliminating a source of bladder irritation. 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.

An ultrasound transceiver scans an organ and processes the echogenic signals to produce three-dimensional, two-dimensional, and one-dimensional information of the organ. The 3-D, 2-D, and 1-D information is utilized to determine the thickness, surface area, volume, and mass of the organ wall.

An apparatus and method are provided to rapidly thaw and heat frozen bags of biological materials, such as plasma. The apparatus has a hollow bladder having a flexible wall that is placed in contact with the bag. A circulation system draws fluid from a reservoir and fills the bladder with the fluid. The circulation system also drains fluid from the bladder. A heater in the reservoir heats the fluid before the fluid enters the bladder. As heated fluid flows through the bladder, heat is transferred through the bladder wall to the plasma bag to thaw the biological material. The bladder wall expands against the plasma bag as the bladder fills with fluid, and contracts from the plasma bag as the bladder is drained. The expansion and contraction of the bladder wall agitates the plasma bag and biological material to accelerate the thawing process.

An ultrasound transceiver scans an organ and processes the echogenic signals to produce three-dimensional, two-dimensional, and one-dimensional information of the organ. The 3-D, 2-D, and 1-D information is utilized to determine the thickness, surface area, volume, and mass of the organ wall.

The present invention provides a pneumatic test plug that seals a portion of a pipe section having a generally cylindrical internal pipe wall. In general, the pneumatic test plug includes an inflation valve mounted in the bladder wall of an inflatable bladder. The inflation valve includes a main air passageway through which air is introduced into the bladder and a separate release channel. The separate release channel includes an inlet disposed toward an interior end of the inflation valve and an outlet in fluid communication with an exterior environment outside the bladder. When in a sealed position, a sealing portion of the bladder engages the interior end of the inflation valve and sealingly closes the inlet of the release channel. When the sealing portion is elastically deflected by overinflation of the bladder, the sealing portion uncovers the inlet of the release channel to allow air to escape from the interior area of the bladder through the release channel to the exterior environment.

The present invention relates to a device and method for accessing an anatomical cavity using a natural body orifice where penetration of a tissue wall is required.

An access device is described suitable for introduction into the bladder, at least partially disinfecting the access site, accessing the abdominal cavity through a wall of the bladder and insufflating the bladder and the abdominal cavity as required. The access device may be used to deliver an endoscope or other diagnostic or therapeutic instruments into the abdominal cavity.

An ultrasound system and method to measure an organ wall weight and mass. When the organ is a bladder, a bladder weight (UEBW) is determined using three-dimensional ultrasound imaging that is acquired using a hand-held or machine controlled ultrasound transceiver. The infravesical region of the bladder is delineated on this 3D data set to enable the calculation of urine volume and the bladder surface area. The outer anterior wall of the bladder is delineated to enable the calculation of the bladder wall thickness (BWT). The UEBW is calculated as a product of the bladder surface area, the bladder wall thickness, and the bladder wall specific gravity.
