Systems for adjusting a position of an implanted medical device within a patient include an engagement tool configured to couple to the implanted medical device. The engagement tool adjusts the position of the medical device when coupled to the implanted medical device. Methods of adjusting a position of an implanted medical device within a patient include locating the implanted medical device, coupling an engagement tool to the medical device, and adjusting a position of the engagement tool to adjust the position of the medical device.
摘要:
Exemplary implantable stimulators for stimulating a stimulation site within a patient include an electronic module configured to generate stimulation and a housing configured to house the electronic module. The housing has a shape allowing the a stimulator and a surgical device to be accommodated together within an insertion tool used to insert the stimulator into the patient. Exemplary methods of stimulating a stimulation site within a patient include generating stimulation with an electronic module and housing the electronic module in a housing. The housing has a shape allowing the housing and a surgical device to be accommodated together within an insertion tool used to insert the housing into the patient.
摘要:
Compact electronic modules, which may be used with implantable microstimulators and other medical and non-medical devices, and manufacture/assembly of such modules are described. Component and circuitry designs utilize unique redistribution techniques and attachment methods. A number of component designs and packaging configurations maximize the volume efficiency of electronic modules. Also included are improved processes and systems enabling the manufacture and assembly of such compact packages.
摘要:
An implantable stimulator that includes a housing, a first plastic component, and a second plastic component, where the first and second plastic components form a polymer-polymer interface. A light absorbing metal layer is disposed over at least a portion of the interface and an electronic subassembly is disposed within the housing. The first and second plastic components can be welded together by irradiating the light absorbing metal layer which converts the light to heat.

An implantable stimulator includes a device for delivering a stimulus and a casing having a first, metal portion and a second, portion which is formed from a plastic or polymer. A method of forming an implantable stimulator includes preparing a coil on a ferrite tube and molding a casing body on the coil, such that the coil is embedded in a wall of the casing which is formed of a plastic or polymer. Another method of forming an implantable stimulator includes forming an annular metal connector and molding a plastic or polymer casing body on the metal connector.

摘要:
Exemplary systems for treating a patient with multiple stimulation therapies include a stimulator configured to automatically apply two or more stimulation signals to a stimulation site via a single channel. Each of the stimulation signals is defined by a distinct set of stimulation parameters. Exemplary methods of treating a patient with multiple stimulation therapies include defining two or more stimulation signals with two or more sets of stimulation parameters and applying the stimulation signals via a single channel to a stimulation site with a stimulator.
摘要:
An implantable microstimulator configured to be implanted beneath a patient's skin for tissue stimulation employs a bi-directional RF telemetry link for allowing data-containing signals to be sent to and from the implantable microstimulator from at least two external devices. Further, a separate electromagnetic inductive telemetry link allows data containing signals to be sent to the implantable microstimulator from at least one of the two external devices. The RF bidirectional telemetry link allows the microstimulator to inform the patient or clinician regarding the status of the microstimulator device, including the charge level of a power source, and stimulation parameter states. The microstimulator has a cylindrical hermetically sealed case having a length no greater than about 27 mm and a diameter no greater than about 3.3 mm. A reference electrode is located on one end of the case and an active electrode is located on the other end of the case.
