Dual communication interface for artificial heart system
First Claim
1. An artificial heart pump system in which a heart pump is implanted in a patient, comprising:
- a pump control unit to be worn by a patient including a programmable device for adapting a secure aspect of heart pump operation in response to pump operating commands, wherein the pump control unit has a wired interface and a wireless interface;
a clinical external unit adapted to be connected to the wired interface for delivering a pump operating command to the pump control unit; and
an auxiliary external unit adapted to be connected to the wireless interface for collecting performance-related data from the pump control unit, wherein the wireless interface is unable to consummate a pump operating command;
wherein the wireless interface is two-way, wherein the pump control unit further includes a first transceiver, wherein at least one of the external units includes a second transceiver, wherein the programmable device determines presence of the at least one external unit by operating the wireless interface in a polling mode, wherein the programmable device operates the wireless interface in a data transfer mode in response to detecting presence of the at least one external unit, wherein the programmable device disables the receiving functionality of the first transceiver during the data transfer mode, and wherein the programmable device automatically sends the performance-related data over the wireless interface when in the data transfer mode.

Abstract
An artificial heart pump system has a heart pump is-implanted in a patient. A pump control unit worn by a patient includes a programmable device for adapting a secure aspect of heart pump operation in response to pump operating commands. The pump control unit has a wired interface and a wireless interface. A clinical external unit is adapted to be connected to the wired interface for delivering a pump operating command to the pump control unit. An auxiliary external unit is adapted to be connected to the wireless interface for collecting patient and/or pump system performance-related data from the pump control unit. The wireless interface is unable to consummate a pump operating command.

13. A method of operating an artificial heart pump system in which a heart pump is implanted in a patient, comprising the steps of:
-
providing pump operating commands to a pump control unit to be worn by a patient, wherein the pump control unit includes a programmable device for adapting a secure aspect of heart pump operation in response to the pump operating commands, wherein the pump control unit has a wired interface for receiving the pump operating commands from a clinical external unit, and wherein the pump control unit has a two-way wireless interface including a first transceiver; the programmable device collecting performance-related data in response to the heart pump operation;
-andoperating the wireless interface of the pump control unit in a polling mode to determine presence of either the clinical external unit or an auxiliary external unit having a second transceiver that responds to the polling mode; and operating the wireless interface of the pump control unit in a data transfer mode in response to detection of one of the external units to automatically send the performance related data, wherein the data transfer mode includes disabling the receiving functionality of the first transceiver. - View Dependent Claims (15, 18)
