Abstract
A flexible sensor configured for use in a bladder is flexible and moveable from a first position in which it is configured to not be discharged from the bladder to a second position in which it is configured to be inserted into the bladder. A sensor insertion tool includes an over sheath, a push rod configured to be inserted into a first lumen of the over sheath. The flexible sensor is positioned in the first lumen of the over sheath, the push rod is then inserted partially into the over sheath behind the flexible sensor. The sensor insertion tool is then positioned at a location, such as the opening to the bladder, in which the sensor is to be deployed.
Core Innovation
The urological monitoring device is configured to be inserted into a body cavity of a subject and includes a tubular housing comprising flexible material with an interior cavity. A circuit board, processor, wireless antenna, battery, and pressure sensor are positioned within the interior cavity and are connected to the circuit board, and the device includes endcaps connected to the tubular housing to support internal components within the interior cavity.
The device disposes an interior fluid within the interior cavity such that an interior cavity pressure is greater than atmospheric pressure, the fluid configured to transmit pressure applied to the tubular housing from inside the subject’s body cavity to the pressure sensor, wherein the interior cavity pressure is at least 1250 hPa. A sealing member comprising a body comprising rubber is arranged within the interior cavity inward from the first section of the first endcap and adjacent to an end of the circuit board.
The sealing member allows a fluid insertion device to pass through a portion of the body of the sealing member to insert the fluid and further self-seals after removal to seal the fluid within the interior cavity at the interior cavity pressure and inhibit external gases from entering the interior cavity. In related variations, the device includes wireless communication with an external computing device via the antenna, and a spacer is arranged within the interior cavity between at least a portion of the first endcap section and at least a portion of the circuit board.
Claims Coverage
The document includes three independent claims. Across them, the inventive coverage centers on an inserted urological monitoring device with internal electronics, a sealed pressurized interior cavity using pressure-transmitting fluid, and a self-sealing rubber member to maintain pressure and inhibit external gases, with an endcap and spacer arrangement relative to the circuit board.
Pressurized interior cavity with pressure-transmitting fluid to a pressure sensor
A fluid disposed within the interior cavity such that an interior cavity pressure is greater than atmospheric pressure, the fluid configured to transmit pressure applied to the tubular housing from inside the subject's body cavity to the pressure sensor, wherein said interior cavity pressure is at least 1250 hPa.
Self-sealing rubber sealing member for fluid insertion and gas inhibition
A sealing member comprising a body comprising rubber, arranged within the interior cavity and configured to allow a fluid insertion device to pass through a portion of the body to insert the fluid within the interior cavity and further configured to self-seal after the fluid insertion device is removed to seal the fluid within the interior cavity at said interior cavity pressure and inhibit external gases from entering the interior cavity.
Wireless urological monitoring device with internal electronics and activation button
A urological monitoring device including a circuit board and internal components comprising a processor, an antenna configured for wireless communication with an external computing device, a battery connected to the circuit board, and a button configured to initiate activation of the urological monitoring device, with a pressure sensor connected to the circuit board.
Endcap and spacer arrangement within the interior cavity relative to circuit board
A first endcap connected to the first end of the tubular housing with a first section positioned within the interior cavity and a second section positioned outside of the interior cavity, and a spacer arranged within the interior cavity between at least a portion of the first section of the first endcap and at least a portion of the circuit board.
The independent claims collectively emphasize a flexible tubular housing with internal wireless electronics and pressure sensing, combined with a sealed interior cavity maintained at at least 1250 hPa above atmospheric pressure using a pressure-transmitting interior fluid, and a rubber sealing member that permits fluid insertion via a fluid insertion device while self-sealing afterward to seal the fluid and inhibit external gases.
Stated Advantages
Maintains interior cavity pressure at least 1250 hPa greater than atmospheric pressure for pressure transmission to the pressure sensor.
Inhibits external gases from entering the interior cavity after fluid insertion due to the self-sealing rubber sealing member.
Documented Applications
Urological monitoring of a subject, including configuration for insertion through a subject’s urethra into the bladder.
