Abstract
An implantable medical pump system configured to selectively permit access to a medicament reservoir by way of at least one contactless key, including an implantable medical pump having an medicament reservoir fluidly couple to an access port via a conduit including an access valve, and at least one contactless key configured to impart a magnetic field upon a portion of the implantable medical pump to manipulate the access valve between a closed position isolating the medicament reservoir from the access port, and an open position fluidly coupling the medicament reservoir to the access port.
Claims22
An implantable medical system configured to selectively permit access to a medicament reservoir by way of at least one contactless key, the implantable medical pump system comprising:
- an implantable medical device including a medicament reservoir fluidly coupled to an access port via a conduit including an access valve configured to selectively isolate the medicament reservoir from the access port;
- and
- at least one programmable coded contactless key, formed with multiple magnetic elements that provide at least one coded magnetic key pattern to manipulate or otherwise configure the access valve between a closed position isolating the medicament reservoir from the access port, and an open position fluidly coupling the medicament reservoir to the access port.
An implantable medical system configured to perform a desired function in the presence of a contactless key, the implantable medical system comprising:
- an implantable medical device having a magnetic sensing element and processor configured to sense the presence of a magnetic field and to perform one or more preprogrammed functions in response to the sensed magnetic field;
- and
- at least one programmable coded contactless key, formed with multiple magnetic elements to impart at least one coded magnetic key pattern upon a magnetic valve in a portion of the implantable medical pump, thereby manipulating or otherwise configuring the magnetic valve between a closed position and an open position.
A method of selectively permitting access to a medicament reservoir of an implanted medical pump by way of at least one contactless key, the method comprising:
- positioning at least one programmable coded contactless key, formed with multiple magnetic elements, in proximity to an implanted medical pump, the implanted medical pump including a medicament reservoir fluidly coupled to an access port via a conduit including an access valve configured to selectively isolate the medicament reservoir from the access port, the multiple magnetic elements positioned to generate at least one coded magnetic key pattern to manipulate or otherwise configure the access valve from a closed position isolating the medicament reservoir from the access port to an open position fluidly coupling the medicament reservoir to the access port.
A method of selectively permitting access to a fluid pathway of an implanted medical port by way of at least one contactless key, the method comprising:
- positioning at least one programmable coded contactless key, formed with multiple magnetic elements, in proximity to an implanted medical port, the implanted medical port including a fluid pathway fluidly coupled to an access port via a conduit including an access valve configured to selectively isolate the fluid pathway from the access port, the multiple magnetic elements positioned to generate at least one magnetic key code to manipulate or otherwise configure the access valve to shift from a closed position isolating the fluid pathway from the access port to an open position fluidly coupling the fluid pathway to the access port.
A method comprising:
- sensing at least one programmable coded contactless key, formed with multiple magnetic elements positioned to generate a magnetic field as at least one magnetic key code, in proximity to an access valve in an implanted medical pump, the implanted medical pump including a medicament reservoir fluidly coupled to an access port via one or more conduits including the access valve configured to selectively isolate the medicament reservoir from the access port;
- and
- determining, by a computer processor and from a magnetic field that is based at least in part on the contactless key, a magnetic key code;
- wherein in response to determining that the magnetic key code authorizes access to an access port of the implanted medical pump, configuring, by the computer processor, the access valve to shift from a closed position isolating the medicament reservoir from the access port to an open position fluidly coupling the medicament reservoir to the access port.
An implantable medical port system configured to selectively permit access to a fluid pathway by way of at least one contactless key, the implantable medical port system comprising:
- an implantable medical port including a fluid pathway fluidly coupled to an access port via a conduit including an access valve configured to selectively isolate the fluid pathway from the access port;
- and
- at least one programmable coded contactless key formed with multiple magnetic elements positioned to generate at least one magnetic key code to manipulate or otherwise configure the access valve between a closed position isolating the fluid pathway from the access port, and an open position fluidly coupling the fluid pathway to the access port.
