[0002] In general, a catheter is a medical device that is used to insert a tube into a patient's body to provide high-frequency treatment to the affected area, inject medical substances into the body, or drain body fluids.

[0003] When performing a procedure using the above catheter, there were cases where the tip of the catheter applied excessive pressure to the patient's affected area, causing damage to the affected area.

[0004] Conversely, if the tip of the catheter comes into contact with the affected area with too little pressure, the affected area may not be properly treated, so the pressure applied by the catheter to the affected area must be precisely measured according to the location and type of procedure.

[0005] The matters described as background technology above are only intended to enhance understanding of the background of the present invention, and should not be taken as an admission that they correspond to prior art already known to those skilled in the art.

[0032] The self-steering catheter device (10) can operate using an application program (or application) in the present disclosure, and this application program can be downloaded from an external server or management server (20) via wireless communication.

[0033] A self-steering catheter device (10) such as this may include a main body (12) and a driving unit (14), as illustrated in FIG. 2.

[0034] The main body (12) may include a communication module (120), a path calculation module (122), a magnetic field calculation module (124), a storage module (126), and a control module (128).

[0035] The communication module (120) can transmit and receive data with the management server (20).

[0036] The path generation module (122) can generate path information using treatment location information based on standard data. That is, the path generation module (122) can generate expected path information expected during treatment and generate treatment path information using the expected path information.

[0037] Specifically, the path calculation module (122) can set an expected procedure point using patient image information acquired before the procedure, and then calculate expected path information from the injection point of the self-steering catheter device (10) to the expected procedure point based on standard data.

[0038] At this time, patient image information may be, but is not limited to, a 3D image, such as a computed tomographic (CT) image or magnetic resonance imaging (MRI) image, obtained before the procedure. Patient image information may be in the form of a video or image.

[0039] In addition, the path generation module (122) can generate treatment path information using expected path information generated based on simulated simulation data.

[0040] The magnetic field generation module (124) can generate magnetic field information using path information based on standard data.

[0042] In addition, the magnetic field generation module (124) can generate treatment magnetic field information using the expected magnetic field information generated based on simulated simulation data.

[0043] After setting the expected procedure point using the patient image information acquired before the procedure, the expected path information can be calculated based on standard data.

[0044] The storage module (126) can store data transmitted and received through the communication module (120) and data supporting various functions of the self-steering catheter device (10).

[0045] The storage module (126) can store a plurality of application programs (or applications) driven by the self-steering catheter device (10), data for the operation of the self-steering catheter device (10), and commands. At least some of these application programs can be downloaded from an external server via wireless communication.

[0046] The power module (126) can supply power to each component included in the self-steering catheter device (10) by receiving external power or internal power under the control of the control module (128). This power module (126) includes a battery (not shown), and the remaining battery level can be visually checked. The battery can be charged by connecting it to a 220V commercial power source or a USB to a laptop or computer.

That is, the control module (128) can repeatedly perform the generation of simulation data until the self-steering catheter device (10) reaches the range of the expected procedure location.

[0055] According to an embodiment, the control module (128) analyzes the simulation data to determine whether the self-steering catheter device (10) moves along the expected path information from the injection point of the self-steering catheter device (10) to the expected procedure point and reaches the expected procedure location within the range of the preset expected movement time, and then can generate procedure path information using the standard data and the simulation data.

[0056] In contrast, the control module (128) analyzes the simulation data and, if the self-steering catheter device (10) moves along the expected path information from the injection point of the self-steering catheter device (10) to the expected procedure point and does not reach the range of the expected procedure location within the range of the preset expected movement time, the control module (128) can regenerate the simulation data based on the standard data.

[0064] The driving unit (12) is a means that comes into direct contact with the body and can serve to inject a scaffold through a catheter at the catheter injection location. The driving unit (12) can be manually operated by a doctor or operated automatically.

[0065] The management server (20) may include a communication unit (22), a database unit (24), a monitoring unit (26), and a management control unit (28).

[0066] The communication unit (22) can transmit and receive data with the self-steering catheter device (10).

[0067] The database unit (24) can store data transmitted and received with the self-steering catheter device (10) via a wireless communication network.

The database unit (24) can store a number of application programs (or applications) running on the management server (20), data for the operation of the management server (20), and commands. At least some of these application programs can be downloaded from an external server via wireless communication.

[0069] The monitoring unit (26) can monitor the operating status of the self-steering catheter device (10) by user operation, the operating status of the management server (20), and data transmitted and received between the self-steering catheter device (10) and the management server (20) through a screen. That is, by checking the usage status of the self-steering catheter device (10) in real time, it is possible to provide more convenience to the user and provide more trust to the user.

[0082] According to an embodiment, the management server (20) may be installed within an electromagnetic drive system to acquire a two-dimensional image including the patient's appearance and depth information in real time during the procedure. At this time, the two-dimensional image may include information acquired in real time, such as two or more CCD images (which may be acquired by a CCD camera) and depth information (which may be acquired using laser, ultrasound, etc.).

[0083] Depending on the embodiment, the management server (20) may also obtain an image aligned with a 3D image and a 2D image.

[0084] According to the embodiment, the management server (20) can generate standard data.

[0085] Next, the management server (20) can predict the treatment point using the patient image information acquired before the treatment and set the expected treatment point in the patient image information (S110).

[0086] Next, the management server (20) can calculate the expected path from the injection point of the self-steering catheter device (10) to the expected treatment point (S120).

[0087] Specifically, the management server (20) can generate expected path information consisting of a path that can reach the expected treatment point from the injection point in a short period of time based on standard data.

[0088] According to an embodiment, when generating expected path information, the management server (20) may generate expected path information consisting of a path that can reach the expected treatment point in the shortest time by considering priorities such as the speed of blood movement in the patient's blood vessels, the size of the blood vessels, the presence or absence of blood vessel blockage, and the patient's age.

[0089] Next, the management server (20) can calculate expected magnetic field information using expected path information based on standard data (S130).

[0090] Specifically, the management server (20) can generate expected magnetic field information consisting of magnetic strength that can reach the expected treatment point from the injection point in a short time using budget path information based on standard data.

[0091] According to an embodiment, when generating the expected magnetic field information, the management server (20) may generate the expected magnetic field information composed of a magnetic intensity that can reach the expected treatment point in the shortest time by considering the priority of the patient's blood flow speed in the blood vessels, the size of the blood vessels, the presence or absence of blood vessel blockage, the patient's age, etc.

[0096] Next, the management server (20) can generate treatment information by analyzing expected treatment information based on standard data, as illustrated in FIG. 4.

[0097] Specifically, the management server (20) can analyze expected treatment information (S200) and generate simulation data (S210).

[0098] For example, the management server (20) can generate simulation data including result data of simulating the expected procedure along the expected path information using the expected magnetic field information from the injection point of the magnetic steering catheter device (10) to the expected procedure point using the expected procedure information.

[0099] Next, the management server (20) can analyze the simulation data to determine whether the expected treatment location range has been reached when moving according to the expected path information.

[0100] That is, the management server (20) can generate treatment path information using the expected path information and simulation data (S240) when the self-steering catheter device (10) moves along the expected path information from the injection point of the self-steering catheter device (10) to the expected treatment point and reaches the range of the expected treatment location (S220), when it reaches within the range of the preset expected movement time according to the expected magnetic field information (S230), and can generate treatment magnetic field information using the expected magnetic field information and simulation data (S250).

[0101] Finally, the management server (20) can generate treatment information using treatment path information and treatment magnetic field information based on standard data (S260).

[0102] That is, the management server (20) can generate treatment information that can be quickly moved to the treatment location in a short period of time.

[0103] Meanwhile, if the self-steering catheter device (10) moves along the expected path information from the injection point of the self-steering catheter device (10) to the expected treatment point and does not reach the range of the expected treatment location (S220), the management server (20) can repeatedly execute the simulation until the range of the expected treatment location is reached.
