Description

Technical Field

[0001] The present disclosure relates to a percutaneous circulatory assist device system. More specifically, the present disclosure relates to a visual display of a circulatory device system designed to provide information corresponding to a percutaneous circulatory assist device and / or a patient's cardiac parameters.

Background Art

[0002] Percutaneous circulatory assist devices such as blood pumps can provide temporary cardiac assistance to patients with reduced cardiac function or cardiac output. Such a device can be inserted percutaneously from the femoral artery, travel retrograde through the descending aorta, cross the aortic arch, cross the aortic valve through the ascending aorta, and be delivered into the left ventricle. To assist clinicians using the circulatory assist device during a medical procedure, a circulatory assist device system can include one or more displays designed to provide easy-to-understand operational information and warning information regarding the percutaneous circulatory assist device, the circulatory assist device system, and / or one or more cardiac parameters of the patient. Therefore, there is a continuing need to provide a circulatory assist device system that includes one or more visual displays designed to provide simplified visual information corresponding to a percutaneous circulatory assist device and / or a patient's cardiac parameters. A circulatory assist device system including one or more visual displays designed to provide information corresponding to a percutaneous circulatory assist device and / or a patient's cardiac parameters is disclosed herein.

[0023] The present invention is subject to various modifications and alternative forms. Specific embodiments are shown by way of example in the drawings and will be described in detail below. However, the intention is not to limit the present invention to the specific embodiments described. On the contrary, the present invention is intended to cover all modifications, equivalents, and alternatives falling within the scope of the present invention as defined by the appended claims.

[0024] FIG. 1 shows an exemplary percutaneous circulatory system 10 including a circulatory assist device 12 disposed in the heart 14 of a patient 16. The circulatory assist device 12 may include a flexible elongated catheter shaft 20 having a first end attached to a handle 22 and a second end attached to a blood pump 24. FIG. 1 shows the blood pump 24 disposed within the left ventricle 18 of the patient 16. The blood pump 24 can be delivered (e.g., advanced) percutaneously into the ventricle 18 over a guide wire. For example, the catheter shaft 20 and the blood pump 24 can be advanced over a guide wire through the femoral artery and the descending aorta, over the aortic arch, through the ascending aorta, past the aortic valve, and into the left ventricle 18.

[0025] In some examples, the shaft 20 of the circulatory support device 12 may include one or more blood inlets located in the distal region of the catheter shaft 20 and one or more blood outlets along the housing of the blood pump 24. In some examples, the blood pump 24 may be located in the heart 14 such that one or more blood inlets located along the distal region of the catheter shaft 20 may be located in the left ventricle 18, and one or more blood outlets located along the housing of the blood pump 24 may be located in the aorta. Furthermore, the blood pump 24 may include an electric motor that drives the rotation of an impeller (located in the housing of the blood pump 24). In some examples, the motor can power the rotation of the impeller via electromagnetic induction. The rotating impeller can draw blood from the left ventricle (through one or more blood inlets located in the distal region of the catheter shaft 2) into the aorta (through one or more inlets located along the housing of the blood pump 24). In other words, the electric motor drives the impeller to pump blood from the left ventricle through the aortic valve into the ascending aorta.

[0026] Figure 1 further shows that the first end of the catheter shaft 20 may be attached to a handle 22. The handle 22 may include a distal end region attached to the catheter shaft 20 and a proximal end region attached to a power cable 26. The power cable 26 may include a distal end region connected to a console 28. It can be understood that the handle 22 may include one or more actuators (e.g., buttons, levers, dials, switches, etc.) designed to allow a clinician to control various functions of the blood pump 24. For example, a clinician may be able to control the speed of a motor and / or impeller located within the blood pump 24 by operating one or more actuators located on the handle 22.

[0027] Furthermore, the percutaneous circulatory system 10 may include one or more sensors positioned along the console 28, the handle 22, the catheter shaft 20, and / or the blood pump 24. One or more sensors positioned in the console 28, in the handle 22, along the catheter shaft 20, and / or in the blood pump 24 may be designed to monitor blood pressure (e.g., arterial pressure, venous pressure), blood flow velocity, blood flow rate, or other parameters. In addition, one or more sensors positioned along the console 28, in the handle 22, in the catheter shaft 20, and / or in the blood pump 24 may be designed to monitor other parameters of the circulatory system 10, the circulatory support device 12, and / or the patient 16. Exemplary parameters that can be sensed and monitored include the electrical connection of the electrical cable 26 to the console 28, optical and / or electrical connections to pressure sensors located in the catheter shaft 20 and / or blood pump 24, the power supply current to the blood pump 24, the impeller speed of the blood pump 24, arterial pressure, venous pressure, the power supply current to the motor, the motor speed, the motor revolutions per minute measurement, the voltage driving the motor, the reverse EMF from the motor, and any combination or temporal pattern of signals corresponding to one or more of the parameters enumerated herein. Furthermore, additional parameters (e.g., flow rate through the blood pump 24) may be derived by processing any combination of signals enumerated herein in a time-dependent manner.

[0028] In addition, Figure 1 shows that the console 28 may include one or more control knobs (e.g., buttons, knobs, dials, etc.) 30 and / or one or more displays. For example, Figure 1 shows that the console 28 may include a first display 32 and a second display 34. It can be understood that the console 28 may include more than two displays. In addition, although Figure 1 shows the first display 32 and the second display 34 integrated into the console 28, it is also conceivable that the circulation system 10 may be designed such that the first display 32, the second display 34, or both the first display 32 and the second display 34 are separate and distinct components of the circulation system 10. In other words, the first display 32, the second display 34, or both the first display 32 and the second display 34 may be separate, standalone displays provided separately from the console 28. In some examples, the first display 32 and the second display 34 may obtain their respective data from separate sources.

[0029] In some examples, the second display 34 may be designed to be mounted on the console 28 and / or the first display 32. For example, the first display 32 may be integrated with the console 28, while the second display 34 may be configured to be mounted on a part of the console 28. In yet another example, both the first display 32 and the second display 34 may be separate, standalone displays, thereby the second display 34 may be configured to be mounted on the first display 32, or the first display 32 may be configured to be mounted on the second display 34.

[0030] Figure 2 shows that the console 28 may include one or more processors 36, memory 38, and I / O units 40, among other suitable components. The processor 36 of the console 28 may include a single processor or two or more processors working individually or in cooperation with each other (for example, a first processor 36 providing data / instructions to a first display 32 and a second processor 36 providing data instructions to a second display 34). The processor 36 may be configured to execute instructions that include instructions that can be loaded into memory 38 and / or other suitable memory. Exemplary processor components may include, but are not limited to, microprocessors, microcontrollers, multicore processors, graphical processing units, digital signal processors, application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), discrete circuits, and / or other suitable types of data processing devices. In some examples, the console's processor 36 may be configured to execute program instructions. Program instructions may include, for example, firmware, microcode, or application code executed by the processor 36, microprocessors, and / or microcontrollers. One or more processors 36 may be configured to manage different functions. They may also be configured to perform the same function simultaneously (e.g., a redundant system). Furthermore, they may be configured such that a first processor 36 performs a given function and a second processor 36 checks the correctness of the result of the first processor 36's function (e.g., a command monitoring system).

[0031] In some examples, the first display 32 may be primarily controlled by console firmware control instructions and therefore may require relatively less processing power, relatively fewer instructions, and very simple communication between the processor 36 and the display 32 compared to a second display 34 (e.g., a touchscreen display 34) which may be primarily controlled by an embedded computer with a flexible and relatively complex communication protocol.

[0032] The memory 38 of the console 28 may include a single memory component or two or more memory components, each working individually or in cooperation with one another. Exemplary types of memory may include random access memory (RAM), EEPROM, FLASH, a suitable volatile storage device, a suitable non-volatile storage device, persistent memory (e.g., read-only memory (ROM), a hard drive, flash memory, optical disc memory, and / or other suitable persistent memory), and / or other suitable types of memory. The memory 38 may be or may include a non-temporary computer-readable medium.

[0033] The I / O unit 40 of the console 28 may include a single I / O component, or two or more I / O components, each working individually or in cooperation with one another. An exemplary I / O unit 40 may be any type of communication port configured to communicate with other components of the circulation system 10. An exemplary type of I / O unit 45 may include wired ports, wireless ports, radio frequency (RF) ports, Low-Energy Bluetooth® ports, Bluetooth® ports, near-field communication (NFC) ports, HDMI® ports, Wi-Fi ports, Ethernet® ports, VGA ports, serial ports, parallel ports, component video ports, S-video ports, composite audio / video ports, DVI ports, USB ports, optical ports, and / or other suitable ports.

[0034] In addition, the first display 32 and / or the second display 34 may include, for example, a CRT, LED, 3D display, or other type of display. The first display 32 and / or the second display 34 can present information relating to the function and operating parameters of the circulatory system 10, the circulatory support device 12, and / or the physiological parameters of the patient 16 in a simple format useful to the clinician. For example, the first display 32 and / or the second display 34 may be configured to display graphic information relating to the electrical connection of the electrical cable 26 to the console 28, the optical connection to the catheter shaft 20 and / or the pressure sensor located in the blood pump 24, the power supply current to the blood pump 24, the impeller speed of the blood pump 24, arterial pressure, venous pressure, the power supply current to the motor, the motor speed, the motor revolutions per minute measurement, the voltage driving the motor, the reverse EMF from the motor, and any combination or temporal pattern of signals corresponding to one or more of the parameters enumerated herein. Furthermore, additional parameters (e.g., flow rate through the blood pump 24) can be derived by processing any combination or temporal pattern of signals corresponding to one or more of the parameters enumerated herein in a time-dependent manner. Additionally, the first display 32 can indicate whether the system 10 is functioning correctly, whether the system 10 has detected a particular problem that may require additional (e.g., non-routine) procedures / adjustments, and / or whether the system 10 has detected a particular problem that requires emergency procedures. Furthermore, the first display 32 may include information indicating that a particular response (e.g., action) is required. For example, the display 32 may indicate that the blood pump 24 is malfunctioning and needs to be replaced immediately during a medical procedure.

[0035] In some examples, the circulatory system 10 may be designed such that the type and / or arrangement of graphic information displayed on the first display 32 differs from the information displayed on the second display 34. For example, in some examples, the second display 34 may be designed to display detailed information about one or more functional, operational, and / or physiological parameters relating to the circulatory system 10, the circulatory support device 12, and / or the patient 16, while the first display 32 may be designed to provide a simplified “global” information status summary about one or more functional, operational, or physiological parameters relating to the circulatory system 10, the circulatory support device 12, and / or the patient 16.

[0036] As can be seen from Figure 1, in some examples, the first display 32 may occupy a smaller area within the console 28 compared to the relatively larger second display 34. Therefore, the first display 32 may be designed to provide a simplified visual information summary that is designed to easily communicate the status of one or more functional, operational, and / or physiological parameters of the circulatory system 10, circulatory support devices 12, and / or patient 16. In some examples, the visual information displayed on the first display 32 may correspond, relate to, or correlate with one or more functional, operational, and / or physiological parameters displayed on the second display 34. However, in other examples, the parameters displayed on the first display 32 may not be related to one or more parameters displayed on the second display 34.

[0037] Figure 3 is a schematic diagram of an exemplary display of the first display 32 described herein. Figure 3 shows the exemplary arrangement and relative positions of one or more symbols (e.g., icons, visual representations, words, symbols, visual alerts, etc.) that may be displayed (e.g., illuminated) on the display 32. As will be described in more detail below, one or more of the symbols may be illuminated on the display 32 in a variety of different configurations.

[0038] The exemplary display 32 shown in Figure 3 may include one or more “visual parameter arrays” arranged side by side relative to one another. For example, Figure 3 shows that the display 32 may include a first visual parameter array 42, a second visual parameter array 44, a third visual parameter array 46, a fourth visual parameter array 48, and a fifth visual parameter array 50. It can be understood that each individual “visual parameter array” 42, 44, 46, 48, 50 may include a collection or cluster of symbols (e.g., icons, visual representations, words, signs, visual alerts, etc.) that together represent specific functional or physiological parameters of the circulatory system 10 and / or the patient 16, in addition to providing information about the “status” of a particular parameter.

[0039] Furthermore, each visual parameter array may include a "visual parameter representation" and one or more "parameter status indicators." For example, the visual parameter array 42 shown in Figure 3 may include a "visual parameter representation" 42a that may include, for example, a symbol (e.g., an icon, visual representation, word, indication, visual alert, etc.) relating to the motor of the blood pump 24 of the circulatory device 12. Furthermore, the visual parameter array 42 shown in Figure 3 may include one or more "parameter status indicators" 42b, 42c, 42d, each of which may include a symbol (e.g., an icon, visual representation, word, indication, visual alert, etc.) that can convey information about the operating state or condition of the motor of the blood pump 24. It can be understood that various functional and physiological parameters of the circulatory system 10 and / or patient 16 can be represented by the visual parameter arrays 42, 44, 46, 48, 50 shown in Figure 3.

[0040] Figure 3 further illustrates that the visual parameter representations and parameter status indicators for each of the visual parameter arrays 42, 44, 46, 48, and 50 can be arranged as a vertical "stack" on the display 32. For example, Figure 3 shows that the visual parameter array 42 may include a first visual parameter representation 42a, a first parameter status indicator 42b, a second parameter status indicator 42c, and a third status parameter indicator 42d, each of which is stacked perpendicularly to each other along the vertical axis 60 of the display 32. Furthermore, Figure 3 shows that the visual parameter array 44 may include a first visual parameter representation 44a, a first parameter status indicator 44b, a second parameter status indicator 44c, and a third status parameter indicator 44d, each of which is stacked perpendicularly to each other along the vertical axis 62 of the display 32. Furthermore, Figure 3 shows that the visual parameter array 46 may include a first visual parameter representation 46a, a first parameter status indicator 46b, a second parameter status indicator 46c, and a third status parameter indicator 46d, each of which is stacked perpendicularly to each other along the vertical axis 64 of the display 32. Furthermore, Figure 3 shows that the visual parameter array 48 may include a first visual parameter representation 48a, a first parameter status indicator 48b, a second parameter status indicator 48c, and a third status parameter indicator 48d, each of which is stacked perpendicularly to each other along the vertical axis 66 of the display 32. Furthermore, Figure 3 shows that the visual parameter array 50 may include a first visual parameter representation 50a, a first parameter status indicator 50b, a second parameter status indicator 50c, and a third status parameter indicator 50d, each of which is stacked perpendicularly to each other along the vertical axis 68 of the display 32.

[0041] Figure 3 shows that the status indicators corresponding to each visual parameter array 42, 44, 46, 48, and 50 can be represented by elongated rectangular shapes. For example, Figure 3 shows the first status indicators 42b, 44b, 46b, 48b, and 50b, the second status indicators 42c, 44c, 46c, 48c, and 50c, and the third status indicators 42d, 44d, 46d, 48d, and 50d, each represented as an elongated rectangular "bar". Therefore, as shown in Figure 3, the first status indicators 42b, 44b, 46b, 48b, 50b may form a horizontal line of rectangular bars extending across the display 32 (each of which may light up individually on the display 32), the second status indicators 42c, 44c, 46c, 48c may form a horizontal line of rectangular bars extending across the display 32 (each of which may light up individually on the display 32), and the third status indicators 42d, 44d, 46d, 48d may form a horizontal line of rectangular bars extending across the display 32 (each of which may light up individually on the display 32). However, it can be understood that any of the status indicators described herein may be represented by any shape on the display 32. For example, any of the status indicators (or visual parameter representations) may be represented by a square, triangle, rectangle, ellipse, circle, star, polygon, or any other shape.

[0042] In addition, it can be understood that any of the symbols (for example, any symbol used as a visual parameter representation or any status indicator as described herein) may be represented using color. For example, in some examples, the first status indicators 42b, 44b, 46b, 48b, 50b may be illuminated using white, the second status indicators 42c, 44c, 46c, 48c, 50c may be illuminated using yellow, and the third status indicators 42d, 44d, 46d, 48d, 50d may be illuminated using red. It can be understood that any color or arrangement of colors may be used to represent and / or illuminate (light up) any symbol on the display 32 (for example, any symbol used as a visual parameter representation or any status indicator).

[0043] In addition, the exemplary display 32 may be configured such that any individual symbols (e.g., icons, visual representations, words, signs, visual alerts, etc.) can be displayed on the display 32 individually or in combination with any other symbols. Furthermore, the symbols displayed on the display 32 (e.g., icons, visual representations, words, signs, visual alerts, etc.) may be related to (e.g., corresponding to, correlated with, etc.) any information displayed on the first display 32.

[0044] Figure 3 shows a display 32 containing five visual parameter arrays 42, 44, 46, 48, and 50, but it can be understood that the display 32 may contain fewer than five visual parameter arrays (each of which may contain one or more visual parameter representations and / or status indicators). Alternatively, it can be understood that the display 32 may contain more than five visual parameter arrays (each of which may contain one or more visual parameter representations and / or status indicators). For example, the display 32 may contain one, two, three, four, five, six, seven, eight, nine, ten or more visual parameter arrays (each of which may contain one or more visual parameter representations and / or status indicators).

[0045] Figure 3 further illustrates that, in some examples, one or more visual parameter representations, a first parameter status indicator, a second parameter status indicator, and / or a third status parameter indicator described in Figure 3 may be aligned horizontally with respect to each other. For example, Figure 3 shows that, in some examples, the visual parameter representations 42a, 44a, 46a, 48a, and 50a may be aligned horizontally with respect to each other along the horizontal axis 52 of the display 32. Furthermore, Figure 3 shows that, in some examples, the first status indicators 42b, 44b, 46b, 48b, and 50b may be aligned horizontally with respect to each other along the horizontal axis 54 of the display 32. Furthermore, Figure 3 shows that, in some examples, the second status indicators 42c, 44c, 46c, 48c, and 50c may be aligned horizontally with respect to each other along the horizontal axis 56 of the display 32. Furthermore, Figure 3 shows that in some examples, the third status indicators 42d, 44d, 46d, 48d, and 50d may be aligned horizontally with respect to one another along the horizontal axis 58 of the display 32.

[0046] Figure 3 shows that in some examples, visual parameter representations and status indicators may be arranged in a specific order along the vertical axis of their respective visual parameter arrays. For example, Figure 3 shows that a visual parameter representation 42a may be positioned between the second status indicator 42c and the third status indicator 42d of the first visual parameter array 42. Figure 3 further shows that each of the other visual parameter arrays 44, 46, 48, 50 shown in Figure 3 may have a similar arrangement to that of visual parameter array 42, thereby positioning each visual parameter representation 44a, 46a, 48a, 50a between the second status indicators 44c, 46c, 48c, 50c and the third status indicators 44d, 46d, 48d, 50d of their respective visual status arrays 44, 46, 48, 50.

[0047] It can be understood that the visual parameter representations and status indicators for any individual visual parameter arrays 42, 44, 46, 48, 50 described herein can be arranged in any given configuration. For example, for any visual parameter array 42, 42, 46, 48, 50, the visual parameter representations 42a, 44a, 46a, 48a, 50a may be arranged in any order with respect to any of the corresponding status indicators. For example, the visual parameter representation 42a may be arranged in any order with respect to the first status indicator 42b, the second status indicator 42c, and the third status indicator 42d of the first visual parameter array 42. For example, the visual parameter representation 42a, the first status indicator 42b, the second status indicator 42c, and the third status indicator 42d may be arranged (from bottom to top along the vertical axis 60) in the order of visual parameter representation 42a, the first status indicator 42b, the second status indicator 42c, and the third status indicator 42d, or in the order of first status indicator 42b, visual parameter representation 42a, the second status indicator 42c, and the third status indicator 42d, or in the order of first status indicator 42b, the second status indicator 42c, the third status indicator 42d, and visual parameter representation 42a. It can be understood that the vertical arrangement of the visual parameter representations and status indicators of other individual visual parameter arrays 44, 46, 48, 50 may be similar to that of the vertical arrangement of the visual parameter 42a described herein.

[0048] Figure 4 shows an exemplary display 134 which may be similar in form and function to the display 32 described herein. Figure 4 shows visual parameter representations 142a, 144a, 146a, 148a, 150a aligned horizontally with respect to each other along the display 134 (similar to the horizontal alignment of visual parameter representations 42a, 44a, 46a, 48a, 50a described with respect to Figure 3). Figure 4 further shows that each of the visual parameter representations 142a, 144a, 146a, 148a, 150a may include symbols (e.g., icons) that may represent specific functional or operational parameters of the circulatory system 10 or physiological parameters of the patient 16. For example, visual parameter representation 142a may include a symbol representing the electrical connection of the electrical cable 26 to the console 28; visual parameter representation 144a may include a symbol representing the location of the blood pump 24 in the patient 16; visual parameter representation 148a may include a symbol representing the amount of suction being applied by the blood pump 24 in the heart 14 of the patient 16; and visual parameter representation 150a may include a symbol representing the speed of the motor driving the impeller of the blood pump 24. Furthermore, Figure 4 shows that in some examples, visual parameter representations 142a, 144a, 146a, 148a, and 150a may include words describing specific functional or operational parameters of the circulatory system 10 or physiological parameters of the patient 16. For example, visual parameter representation 146a shown in Figure 4 includes the word "MAP" representing the "Mean Arterial Pressure" in the aorta of the patient's heart 16. However, it is intended that the visual parameter representation 146a may also be represented by icons, similar to the other visual parameter representations 142a, 144a, 148a, and 150a shown in Figure 4.

[0049] Figure 4 further shows that the first status indicators 142b, 144b, 146b, 148b, 150b may be vertically aligned with each of the visual parameter representations 142a, 144a, 146a, 148a, 150a. The first status indicators 142b, 144b, 146b, 148b, 150b may be the same as the first status indicators 42b, 44b, 46b, 48b, 50b described with respect to Figure 3. Figure 4 further shows that the first status indicators 142b, 144b, 146b, 148b, 150b may be horizontally aligned with each other, similar to the first status indicators 42b, 44b, 46b, 48b, 50b described with respect to Figure 3.

[0050] Figure 5 shows another exemplary display 234 which may be similar in form and function to the displays 34,134 described herein. Figure 5 shows visual parameter representations 242a,244a,246a,248a,250a aligned horizontally with respect to display 234 (similar to the horizontal alignment of visual parameter representations 42a,44a,46a,48a,50a described with respect to Figure 3). Figure 5 further shows that each of the visual parameter representations 242a,244a,248a,250a may contain words (e.g., describe, show) that represent specific functional or operational parameters of the circulatory system 10 or physiological parameters of the patient 16. For example, visual parameter representation 242a may include the word "connection" which may represent the electrical connection of the electrical cable 26 to the console 28; visual parameter representation 244a may include the word "position" which may represent the position of the blood pump 24 in the patient 16; visual parameter representation 246a may include the word "pressure" which may represent a specific blood pressure (e.g., mean arterial pressure) in the patient's heart 16; visual parameter representation 248a may include the word "suction" which may represent the amount of suction applied by the blood pump 24 in the patient's heart 14; and visual parameter representation 250a may include the word "motor" which may represent the speed of the motor driving the impeller of the blood pump 24.

[0051] Figure 5 further shows that the first status indicators 242b, 244b, 246b, 248b, and 250b may be vertically aligned with each of the visual parameter representations 242a, 244a, 246a, 248a, and 250a. The first status indicators 242b, 244b, 246b, 248b, and 250b may be the same as the first status indicators 42b, 44b, 46b, 48b, and 50b described with respect to Figure 3. Figure 4 further shows that the first status indicators 242b, 244b, 246b, 248b, and 250b may be horizontally aligned with each other, similar to the first status indicators 42b, 44b, 46b, 48b, and 50b described with respect to Figure 3.

[0052] Figure 6 shows another exemplary display 334 which may be similar in form and function to other displays described herein. Figure 6 shows visual parameter representations 342a, 344a, 346a, 348a, 350a aligned horizontally with each other along display 334 (similar to the horizontal alignment of visual parameter representations 42a, 44a, 46a, 48a, 50a described with respect to Figure 3). Figure 6 further shows that each of the visual parameter representations 342a, 344a, 348a, 350a may include symbols (e.g., icons) that may represent specific functional or operational parameters of the circulatory system 10 or physiological parameters of the patient 16 (similar to the icons described with respect to Figure 4). Furthermore, Figure 6 further shows the first status indicators 342b, 344b, 346b, 348b, 350b represented by circles, thereby aligning each of the circular status indicators 342b, 344b, 346b, 348b, 350b with respect to the horizontal axis 354. Furthermore, Figure 6 shows the second status indicators 342c, 344c, 346c, 348c, 350c represented by larger circles (relative to the circles representing the status indicators 342b, 344b, 346b, 348b, 350b), thereby aligning each of the circular status indicators 342c, 344c, 346c, 348c, 350c with respect to the horizontal axis 356. Furthermore, Figure 6 shows third status indicators 342d, 344d, 346d, 348d, 350d represented by even larger circles (relative to the circles representing status indicators 342b, 344b, 346b, 348b, 350b and status indicators 342c, 344c, 346c, 348c, 350c), thereby aligning each of the circular status indicators 342d, 344d, 346d, 348d, 350d with one another along the horizontal axis 358.In addition, Figure 6 shows that the first status indicators 342b, 344b, 346b, 348b, 350b, the second status indicators 342c, 344c, 346c, 348c, 350c, and the third status indicators 342d, 344d, 346d, 348d, 350d shown on the display 334 are not aligned with each other along a given vertical axis. As described herein, any of the status indicators (or visual parameter representations) shown in Figure 6 may be represented by any shape, including squares, triangles, rectangles, ellipses, circles, stars, polygons, and the like.

[0053] Figure 7 shows an exemplary display 432 which may be similar in form and function to the display 32 described herein. Figure 7 shows visual parameter representations 442a, 444a, 446a, 448a, and 450a aligned horizontally with respect to each other along the display 432 (similar to the horizontal alignment of the visual parameter representations 42a, 44a, 46a, 48a, and 50a described with respect to Figure 3). Figure 7 further shows that each of the visual parameter representations 442a, 444a, 446a, 448a, and 450a may include symbols (e.g., icons) that may represent specific functional or operational parameters of the circulatory system 10 or physiological parameters of the patient 16. For example, visual parameter representation 442a may include a symbol representing the electrical connection of the electrical cable 26 to the console 28; visual parameter representation 444a may include a symbol representing the speed of the motor driving the impeller of the blood pump 24; visual parameter representation 446a may include a symbol representing the amount of suction being applied by the blood pump 24 in the patient's heart 14; and visual parameter representation 448a may include a symbol representing the location of the blood pump 24 in the patient 16. Furthermore, Figure 7 shows that in some examples, visual parameter representations 442a, 444a, 446a, 448a, and 450a may include words describing specific functional or operational parameters of the circulatory system 10 or physiological parameters of the patient 16. For example, visual parameter representation 450a shown in Figure 7 includes the word "MAP" representing the "mean arterial pressure" in the aorta of the patient's heart 16. However, it is intended that the visual parameter representation 450a may also be represented by an icon, similar to the other visual parameter representations 442a, 444a, 446a, and 448a shown in Figure 7.

[0054] Figure 7 further shows that the first status indicators 442b, 444b, 446b, 448b, 450b may be vertically aligned with each of the visual parameter representations 442a, 444a, 446a, 448a, 450a. The first status indicators 442b, 444b, 446b, 448b, 450b may be the same as the first status indicators 42b, 44b, 46b, 48b, 50b described with respect to Figure 3. Figure 7 further shows that the first status indicators 442b, 444b, 446b, 448b, 450b may be horizontally aligned with each other, similar to the first status indicators 42b, 44b, 46b, 48b, 50b described with respect to Figure 3.

[0055] As described herein, each of the visual parameter arrays 42, 44, 46, 48, and 50 illustrated and described herein can identify (e.g., represent, symbolize, etc.) specific functional or operational parameters of the circulatory system 10 or physiological parameters of the patient 16, while also conveying information regarding the “status” of that particular parameter during a medical procedure. For example, the display 32 can be configured to present status information regarding the functional parameters of the circulatory system 10 or the physiological parameters of the patient 16 in a simple and easy-to-understand format, so that a clinician can easily determine from the display 32 the status of each parameter represented by the visual parameter arrays 42, 44, 46, 48, and 50.

[0056] Therefore, in some examples, the first, second, and third status indicators of a given visual parameter array may provide real-time, stepwise (e.g., progressive) status information (e.g., alert indicators) corresponding to functional or physiological parameters of the system 10 or patient 16. Figures 8 to 10 show a display 32 progressing through stepwise status indicators (e.g., alert indicators) corresponding to exemplary parameters of the system 10 (e.g., electrical connections between electrical cables 26 and console 28). Therefore, in some examples, the visual parameter representation 42a shown in Figure 8 may include symbols (e.g., icon 142a shown in Figure 3) that inform the clinician that the visual parameter array 42 represents the electrical connections between electrical cables 26 and console 28 of the system 10. Furthermore, Figure 8 shows a display 32 displaying a first status indicator 44b (without displaying status indicators 44c, 44d) located below the visual parameter representation 42a on the horizontal axis 54. The display of the first status indicator 44b can communicate that the electrical connection between the electrical cable 26 and the console 28 is in an "information / advice" (e.g., normal, routine, etc.) operating state (e.g., a sufficient amount of current is being transmitted between the console 28 and the circulatory support device 12 along the electrical cable 26). In other words, the display of any of the first status indicators 42b, 44b, 46b, 48b, or 50b can communicate to the clinician that the parameters associated with the first status indicators 42b, 44b, 46b, 48b, or 50b are operating in a normal (e.g., routine) operating state.

[0057] Furthermore, in some examples, the processing system of system 10 may be programmed to define a range of values, a minimum threshold, a maximum threshold, etc., that define the “information / advice” operating state of a particular parameter to which a given first indicator 42b, 44b, 46b, 48b, 50b relates. As shown in Figure 8, when each of the first status indicators 42b, 44b, 46b, 48b, 50b is displayed (for example, a solid line of the first indicators 42b, 44b, 46b, 48b, 50b is displayed along the horizontal axis 54), the display 32 informs the clinician that all parameters represented by the visual parameter arrays 42, 44, 46, 48, 50 are operating in a normal operating state and no user action is required.

[0058] Figure 9 shows a display 32 displaying a second status indicator 42c for a parameter represented by a visual parameter representation 42a (e.g., the electrical connection between the electrical cable 26 and the console 28). Figure 9 shows that the state of the visual parameter representation 42a has changed from an information / advisory action state (represented by status indicator 42b) to a "critical" state (e.g., an early warning state) (represented by status indicator 42c), which can indicate that a functional, operational, or physiological parameter represented by the visual parameter representation 42a has moved outside the information / advisory action range and entered a critical state, potentially requiring user action, and that the parameter may require improvement, adjustment, etc. (e.g., the current transmitted along the electrical cable 26 between the console 28 and the circulatory assistance device 12 may be in a dangerous state).

[0059] Furthermore, in some examples, the processing system of system 10 may be programmed to define a range of values, a minimum threshold, a maximum threshold, etc., that define the “serious” operating state of a particular parameter to which a given second status indicator 42c, 44c, 46c, 48c, 50c relates.

[0060] Figure 9 shows that the second status indicator 42c (located on the horizontal axis 56) is displayed, while the status indicator 42b (which was located on the horizontal axis 54) is no longer displayed. In other words, by comparing the display shown in Figure 8 with the display shown in Figure 9, it is shown that the "status" of the parameter represented by the visual parameter representation 42a (e.g., icon 142a shown in Figure 3) (e.g., the electrical connection between the electrical cable 26 and the console 28) has moved up the vertical axis 60 of the visual parameter array 42. As shown in Figure 9, a clinician can quickly look at the display 32 shown in Figure 9 and understand that the status of the parameter represented by the visual parameter representation 42a has shifted from the first status indicator 42b to the second status indicator 42c. Furthermore, from the display 32 shown in Figure 9, it can be understood that the status of the parameters corresponding to the remaining visual parameter arrays 44, 46, 48, and 50 remains in an information / advisory operating state.

[0061] Figure 10 shows a display 32 that displays a status indicator 42d for a parameter represented by a visual parameter representation 42a (e.g., the electrical connection between the electrical cable 26 and the console 28). Figure 10 shows that the state of the visual parameter representation 42a has changed from a serious state to a "critical" state, which may indicate that a functional, operational, or physiological parameter represented by the visual parameter representation 42a has moved out of the early warning range and entered a critical state, thereby requiring immediate user action, potentially requiring parameter modification, and / or potentially requiring the cessation of medical treatment (e.g., the circulatory support device 12 is no longer receiving power from the console 28, and therefore the blood pump 24 is unable to function).

[0062] Figure 10 shows that the third status indicator 42d (located on the horizontal axis 58) is displayed, while the status indicator 42c (which was located on the horizontal axis 56 in Figure 9) is no longer displayed. In other words, by comparing the display shown in Figure 9 with the display shown in Figure 10, it is shown that the "status" of the parameter represented by the visual parameter representation 42a (e.g., icon 142a shown in Figure 3) (e.g., the electrical connection between the electrical cable 26 and the console 28) has moved up the vertical axis 60 of the visual parameter array 42. As shown in Figure 10, a clinician can quickly look at the display 32 shown in Figure 10 and understand that the status of the parameter represented by the visual parameter representation 42a has shifted from the second status indicator 42c to the third status indicator 42d. Furthermore, from the display 32 shown in Figure 10, it can be understood that the status of the parameters corresponding to the remaining visual parameter arrays 44, 46, 48, and 50 remains in an information / advisory operational state.

[0063] In addition, in some cases, the hiding of status indicators within visual parameter arrays 42, 44, 46, 48, and 50 may communicate to the clinician that the status of the parameter represented by the visual parameter representation is unknown or has not yet been determined at that time.

[0064] Furthermore, in some examples, the processing system of system 10 may be programmed to define a range of values, a minimum threshold, a maximum threshold, etc., that define the “critical” operating state of a particular parameter to which a given second status indicator 42d, 44d, 46d, 48d, 50d relates.

[0065] Figure 11 shows another example in which the display 32 communicates information about the status of functional, operational, or patient parameters by displaying different status indicators for multiple visual parameter arrays 42, 44, 46, 48, 50. Figure 11 shows how the display 32 may be designed to present the status of system 10 and / or patient 16 parameters in an easily understandable format so that a clinician can easily determine the status of each parameter represented by the visual parameter arrays 42, 44, 46, 48, 50 from the display 32.

[0066] For example, Figure 11 shows that the first status indicators 42b and 50b are displayed on the horizontal axis 54, thereby informing the clinician that the parameters represented by the visual parameter representations 42a and 50a are operating in an "information / advice" operational status. Figure 11 further shows that the second status indicator 44c is displayed on the horizontal axis 56, thereby informing the clinician that the parameters represented by the visual parameter representation 44a are operating in a "critical" operational status. Furthermore, Figure 11 shows that the third status indicator 46d is displayed on the horizontal axis 58, thereby informing the clinician that the parameters represented by the visual parameter representation 46a are operating in a "critical" operational status. Finally, Figure 11 shows that no status indicators are displayed for the visual parameter array 48. Therefore, since no status indicator is displayed for the visual parameter array 48, it can be understood that the status of the parameter represented by the visual parameter representation 48a is unknown. For example, if the visual parameter representation 48a represents the location of the blood pump in the patient, the absence of the status indicator in the visual parameter array 48 can inform the clinician that the location of the patient's blood pump is unknown at that time. Furthermore, once the location of the blood pump becomes known, the status indicator (as described herein) can appear in the visual parameter array 48, thereby informing the clinician of the operational status of the location of the blood pump in the patient.The display configuration shown in Figure 11 allows clinicians to quickly understand that the parameters represented by visual parameter representations 42a and 50a are operating in an information / advisory state, that the parameters represented by visual parameter representation 44a may need adjustment, that the parameters represented by visual parameter representation 46a may need immediate modification, or that a medical procedure should be stopped and the status of the parameters represented by visual parameter representation 48a is unknown.

[0067] In some examples, it can be understood that a status indicator in a given visual parameter array may remain displayed while other status indicators in the visual parameter array are displayed. In other words, the display 32 may be configured to operate such that a first status indicator is displayed during normal operating conditions, a second status indicator is displayed during serious conditions (therefore, the first status indicator remains displayed along with the second status indicator), and a third status indicator may be displayed during critical conditions (therefore, the first and second status indicators may remain displayed along with the third indicator).

[0068] Figure 12 shows an alternative arrangement of the visual parameter arrays 42, 44, 46, 48, 50 described with respect to Figure 3. Figure 12 shows that the display 32 described with respect to Figure 3 may be arranged such that the visual parameter representations 42a, 44a, 46a, 48a, 50a are aligned perpendicularly to one another. Figure 12 shows the visual parameter representations 42a, 44a, 46a, 48a, 50a aligned perpendicularly along the vertical axis 80. Furthermore, Figure 12 shows that each of the first, second, and third status indicators corresponding to each individual visual parameter representation 42a, 44a, 46a, 48a, 50a may be aligned horizontally with their respective visual parameter representations 42a, 44a, 46a, 48a, 50a on the horizontal axis. For example, Figure 12 shows a visual parameter representation 42a aligned horizontally with a first status indicator 42b, a second horizontal indicator 42c, and a third horizontal indicator 42d along the horizontal axis 70. Figure 12 further shows a visual parameter representation 44a aligned horizontally with a first status indicator 44b, a second horizontal indicator 44c, and a third horizontal indicator 44d along the horizontal axis 72. Figure 12 further shows a visual parameter representation 46a aligned horizontally with a first status indicator 46b, a second horizontal indicator 46c, and a third horizontal indicator 46d along the horizontal axis 74. Figure 12 further shows a visual parameter representation 48a aligned horizontally with a first status indicator 48b, a second horizontal indicator 48c, and a third horizontal indicator 48d along the horizontal axis 76. Figure 12 further shows a visual parameter representation 50a aligned horizontally with a first status indicator 50b, a second horizontal indicator 50c, and a third horizontal indicator 50d along the horizontal axis 78.
