Methods and systems are described for managing synchronous conducted communication for an implantable medical device (IMD). The IMD further comprises electrodes and sensing circuitry. The sensing circuitry is configured to detect physiologic events. A receiver amplifier is coupled to the electrodes. The receiver amplifier is configured to receive conducted communications signals via the electrodes. A controller is configured to establish synchronous conducted communication with a transmit device. The controller includes a receive window timing (RWT) module configured to manage an on-off cycle of the receiver amplifier based on first and second receive window timing schemes. The RWT module switches between the first and second receive window timing schemes based on a condition of the synchronous conducted communication.

Methods and systems for managing synchronous conducted communication for an implantable medical device

Systems, devices and methods to facilitate wireless interaction between an implantable therapy delivery device and an external transmitter device are provided. In an example, the systems, devices, and methods discussed herein include or use a garment for receiving and positioning an external transmitter device proximal to an implanted device, and the external transmitter device includes a midfield device configured to provide one or more signals to manipulate evanescent fields outside of tissue to generate a propagating and focused field in the tissue. In an example, the garment includes a receptacle configured to receive and retain the external transmitter device near a tissue interface, and the garment further includes a dielectric portion provided between the receptacle and the tissue interface. In an example, the dielectric portion has a relative permittivity that is approximately the same as the relative permittivity of air.

Described herein are apparatuses and methods that improve conductive communication between an external programmer and an implantable medical device (IMD) that is implanted within a patient. In an embodiment, an auxiliary apparatus of the present technology includes a first auxiliary skin electrode configured to attach to skin of a patient, a second auxiliary skin electrode configured to attach to skin of a patient, and an electrically conductive path extending between the first and second auxiliary skin electrodes and interrupted by a capacitor. The auxiliary apparatus is distinct from the external programmer and the IMD, and can beneficially be used to improve conductive communication therebetween without making any modifications to the external programmer, and without making any modifications to the IMD.

Apparatuses and methods that improve conductive communication between external programmers and implantable medical devices

A medical device for diagnosis or treatment of tissue is disclosed. The device includes an electronically-controlled tool configured for diagnosis or treatment, an electrical connector, and a computer readable memory. The electrical connector is configured for connection with an electronic control unit and configured to receive control signals, including signals concerning the operation of the tool, from the electronic control unit. The computer readable memory is accessible through the connector. The memory can include a set of programming instructions for control of the tool, and the programming instructions can be configured to be downloadable from the memory upon connection of the electrical connector with the electronic control unit. A system is also disclosed in which the electronic control unit is configured to transmit a data log from memory in the electronic control unit to the memory in the medical device upon the occurrence or detection of a predetermined event.

Integration of control software with a medical device and system

An implantable medical device (IMD) is configured to be implanted within a patient. The IMD may include a controller configured to adjust a communication frequency, a housing formed of an electrically common material, and an insulating cover coupled to the housing. The insulating cover may include one or both of at least one opening or at least one thinned area over portions of the housing. Multiple sub-electrodes are formed in the housing through the opening(s) or the thinned area(s).

Systems and methods for implantable medical device communication

Systems and methods for providing communications between an external device and first and second leadless pacemakers (LPs) located in a heart are provided. A method includes receiving first and second event messages from the first and second LPs, the first and second event messages received at different points in time at the external device, determining the signal strengths of the first and second event messages, respectively, as received at the external device, adjusting first and second LP discrimination thresholds based on the received signal strengths of the first and second event messages, respectively, and utilizing the first and second LP discrimination thresholds to identify which of the first and second LP transmits subsequent event messages, in order for the external device to independently communicate with the first and second LPs.

Dual chamber leadless pacemaker programmer and method

A leadless pacemaker for pacing a heart of a human includes a hermetic housing and at least two electrodes on or near the hermetic housing. The at least two electrodes are configured to deliver energy to stimulate the heart and to transfer information to or from at least one external device.

An ablating device has a cover which holds an interface material such as a gel. The cover contains the interface material during initial placement of the device. The ablating device may also have a removable tip or a membrane filled with fluid. In still another aspect, the ablating device may be submerged in liquid during operation.

Methods and devices for ablation

A system and method for using a common subchannel to assess operating characteristics of one of a plurality of transducers coupled to said subchannel is disclosed. The transducers are divided into subsets, with each subset is coupled to a subchannel. The system is configured to activate a selected transducer on the subchannel and the subchannel delivers operational information on the activated transducer. The present invention reduces the number of subchannels required to collect information on the plurality of transducers. The present invention permits a more compact ablation device to be constructed based on the invention's ability to reduce the total number of subchannels required to collect transducer information.

Method and system for using common subchannel to assess the operating characteristics of transducers

A high intensity focused ultrasound transducer includes an ultrasonic emitter having a surface that emits ultrasonic energy along a beam path, at least one low attenuation polymeric ultrasonic lens acoustically coupled to the surface in the beam path of the ultrasonic energy, such that the lens can direct the ultrasonic energy in at least one direction, and at least one stress mitigation feature, such as a kerf, a heat sink, or an acoustic matching layer, to mitigate thermal expansion mismatch stresses within the transducer. For manufacturing simplicity, the first surface is typically either flat or monotonically curvilinear. The lens may take a variety of shapes, including Fresnel features, and may focus, collimate, or defocus the ultrasonic energy. Any orientation and positioning of the at least one ultrasonic lens relative to the first ultrasonic emitter is contemplated. Manufacture is further simplified by molding, casting, or thermoforming the lens.

A control system alters one or more characteristics of an ablating element to ablate tissue. In one aspect, the control system delivers energy nearer to the surface of the tissue by changing the frequency or power. In another aspect, the ablating element delivers focused ultrasound which is focused in at least one dimension. The ablating device may also have a number of ablating elements with different characteristics such as focal length.
