Abstract
The present invention provides for an access port configured to detect its tilt within the body to facilitate a physician's access thereto. The access port can include a tilt detector to detect tilt datum, and a display screen to display the tilt of the access port. In addition, the tilt detector and the display screen can indicate whether the access port is flipped or not. The tilt detector can include an accelerometer to aid in determining the tilt of the access port.
Claims22
An access port for connecting to a gastric band for the treatment of obesity, the gastric band suitable for laparoscopic placement around the stomach of a patient to create a stoma, the access port comprising:
- a housing defining a cavity and comprising a penetrable septum defining an outer wall of the housing;
- a conduit configured to carry fluid between the penetrable septum and an inflatable portion of the gastric band;
- and
- a tilt detector coupled to the housing and configured to determine an orientation of the housing relative to a surface of a skin of the patient.
An access port for connecting to a gastric band for the treatment of obesity, the gastric band suitable for laparoscopic placement around the stomach of a patient to create a stoma, the access port comprising:
- a penetrable septum defining an outer wall of a housing;
- a conduit configured to carry fluid between the penetrable septum and an inflatable portion of the gastric band;
- and
- a tilt detector coupled to the housing and configured to detect a tilt direction of the housing relative to a body portion of the patient and a degree tilt of the housing relative to a surface of a skin of the patient.
An access port for connecting to a gastric band for the treatment of obesity, the gastric band suitable for laparoscopic placement around the stomach of a patient to create a stoma, the access port comprising:
- a penetrable septum defining an outer wall of a housing;
- a conduit configured to provide fluid communication between the penetrable septum and the gastric band;
- and
- a pressure sensor in fluid communication with a fluid within the gastric band and configured to monitor a pressure of the fluid, generate a pressure value signal, and communicate the pressure value signal to an external control unit via RF telemetry.
An access port for connecting to a gastric band for the treatment of obesity, the gastric band suitable for laparoscopic placement around the stomach of a patient to create a stoma, the access port comprising:
- a penetrable septum defining an outer wall of a housing;
- a conduit configured to provide fluid communication between the penetrable septum and the gastric band;
- and
- a tilt detector coupled to the housing and configured to detect a tilt datum indicating a tilt direction of the access port relative to a body portion of the patient and a degree tilt of the access port relative to a surface of a skin of the patient.
A method of determining a contact between a needle of a syringe and an implanted access port comprising:
- detecting vibration data using the implanted access port;
- and
- analyzing the vibration data to determine whether the syringe has contacted the implanted access port.
A method of determining an insertion of a needle of a syringe into an implanted access port comprising:
- tilting the needle of the syringe;
- determining tilt datum of the implanted access port;
- and
- analyzing the tilt datum to determine whether the implanted access port is tilted when the needle of the syringe is tilted.
