Abstract
Abstract A medical implant valve, for example, a glaucoma valve, is configured to be non-invasively adjustable. A rotor is operatively coupled to the valve to enable the position of valve to be adjusted between an open and closed position; the rotor being responsive to a magnetic field. An external instrument is used to control rotation of the rotor.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
60 words
A medical implant, comprising: a non-invasively adjustable implantable medical valve having open and closed positions, said medical valve being continuously adjustable between said open and closed positions by an external magnetic field; and an implanted circuit configured to provide an indication in response to said external magnetic field representative of the position of said valve after it has been implanted.
Claim 2
Dependent Claim
60 words
A medical implant, comprising: a non-invasively adjustable implantable medical valve having open and closed positions, said medical valve being continuously adjustable between said open and closed positions by an external magnetic field; and an implanted circuit configured to provide an indication in response to said external magnetic field representative of the position of said valve after it has been implanted.
Claim 3
Dependent Claim
28 words
A medical implant according to claim 1, wherein said medical valve includes a rotatable armature responsive to said magnetic field to adjust the position of the medical valve.
Claim 4
Dependent Claim
31 words
A medical implant according to claim 2, wherein said medical valve includes a rotor operably coupled to said rotatable armature, and configured to drive said armature responsive to said magnetic field.
Claim 5
Dependent Claim
14 words
A medical implant according to claim 1, wherein said circuit includes a resonant circuit.
Claim 6
Dependent Claim
21 words
A medical implant according to claim 4, a frequency of said resonant circuit configured to be read by an external device.
Claim 7
Independent Claim
56 words
A system for controlling fluid flow in a body, comprising: an implant having an adjustable valve, said valve including means for providing a position indication in response to an external magnetic field of the position of the valve; and an external device for non-invasively adjusting the position of said valve in response to said position indication.
Claim 8
Independent Claim
56 words
A system for controlling fluid flow in a body, comprising: an implant having an adjustable valve, said valve including means for providing a position indication in response to an external magnetic field of the position of the valve; and an external device for non-invasively adjusting the position of said valve in response to said position indication.
Claim 9
Dependent Claim
11 words
A system according to claim 6, said valve being magnetically adjustable.
Claim 10
Dependent Claim
22 words
A system according to claim 7, said implant including a resonant circuit, said resonant circuit responsive to a setting of said valve.
Claim 11
Dependent Claim
14 words
A system according to claim 8, said resonant circuit readable by said external instrument.
Claim 12
Dependent Claim
15 words
A system according to claim 7, said valve being adjustable by a rotating magnetic field.
Claim 13
Dependent Claim
19 words
A system according to claim 10, said implant including a rotor configured to respond to said rotating magnetic field.
Claim 14
Dependent Claim
14 words
A system according to claim 11, said rotor operably coupled to a rotatable armature.
Claim 15
Independent Claim
56 words
A method for controlling an implantable device having an adjustable valve the method comprising: receiving an electronic signal indicative of the position of the valve in said implantable device; applying a magnetic field to adjust the position of said valve in said implantable device between an open position and closed position in response to said signal.
Claim 16
Independent Claim
56 words
A method for controlling an implantable device having an adjustable valve the method comprising: receiving an electronic signal indicative of the position of the valve in said implantable device; applying a magnetic field to adjust the position of said valve in said implantable device between an open position and closed position in response to said signal.
Claim 17
Dependent Claim
17 words
A method according to claim 13, wherein said magnetic field is applied from external to said device.
Claim 18
Independent Claim
81 words
A method for varying the intraocular pressure of a subject comprising the steps of: (a) implanting a continuously adjustable valve, said valve configured to relieve said ocular pressure as a function of the position of said valve; (b) initially setting the position of said valve at the time of the implant; (c) non-invasively checking the position of the valve after implant; and (d) externally changing the position of the valve in response to the information regarding the position of the valve.
Claim 19
Independent Claim
81 words
A method for varying the intraocular pressure of a subject comprising the steps of: (a) implanting a continuously adjustable valve, said valve configured to relieve said ocular pressure as a function of the position of said valve; (b) initially setting the position of said valve at the time of the implant; (c) non-invasively checking the position of the valve after implant; and (d) externally changing the position of the valve in response to the information regarding the position of the valve.
