An electronic device includes a processor configured to generate a position movement prediction field indicating prediction of a potential positional change of a branch path by a patient's biological activity for one or more branch paths based on a blood vessel image of a reference frame, correct guidewire information extracted from a blood vessel image of a target frame with respect to a catheter position of the reference frame, and select a branch path to dispose the guidewire information, among one or more branch paths of a blood vessel region based on the position movement prediction field and the corrected guidewire information; and a display configured to visualize the guidewire information on the selected branch path.

A puncture needle assembly (1000) and a puncture system (100) are provided. The puncture needle assembly (1000) includes a needle holder (1100) and a needle (1200). The needle holder (1100) comprises a channel axially extending therethrough. The channel has a sidewall, at least a part of which is provided by a conductor (1110). The needle (1200) has a proximal end portion extending in the channel and electrically connected to the conductor (1110). The puncture system (100) includes the puncture needle assembly (1000) and a dilator (2000). The dilator (2000) includes a dilation catheter (2100) and an optional conductive biasing member (2200) disposed on the dilation catheter (2100). Even when a distal end of the needle (1200) is hidden in the dilation catheter (2100), the conductive biasing member (2200) can still establish an electrical connection between the needle and the blood outside thereof. The puncture needle assembly (1000) and the puncture system (100) have the advantages of ease of use and high reliability.

A system for superimposing virtual anatomical landmarks on an image includes a medical positioning system (MPS) for producing location readings with respect to points within a region of interest in accordance with an output of a location sensor disposed in a medical device. A coordinate system of the MPS is registered with an image coordinate system. A control unit receives a signal from a user to record a location reading when the medical device is at a desired point in the region of interest where the user desires to place a virtual landmark, modifies the recorded location reading for motion compensation, transforms the motion-compensated location reading from the MPS coordinate system to the image coordinate system to produce a target location, and then superimposes a representation of the virtual landmark on the image at the target location.

A medical device is provided. The medical device includes a puncture needle that is inserted into body tissue from outside a body and pierces membranous tissue near pulsating tissue inside the body tissue; a tubular protection member that is disposed on the outer side of the puncture needle; a pulse-information acquisition portion that acquires pulse information of the pulsating tissue; and a driving unit that moves the puncture needle and the protection member relative to each other in synchronization with the pulse information of the pulsating tissue acquired by the pulse-information acquisition portion, in such a manner that a tip of the puncture needle is retracted toward a proximal end from a distal end of the protection member when the pulsating tissue expands and that the tip of the puncture needle is projected farther forward from the distal end of the protection member when the pulsating tissue contracts.

A system and method including a guide wire having a plurality of sensors attached near an end of the guide wire, and a processor configured to determine a position of a body component and a position of a catheter moving along the guide wire based on the signals received from the plurality of sensors. Feedback information can be generated based on these determined positions to help guide a medical procedure.

In a method, system and device a member is provided around an aneurysm enabling treatment and monitoring of the aneurysm. In accordance with one embodiment the device is adapted to be adjusted postoperatively. Hereby the treatment can be efficiently carried out without having to perform surgery when adjusting the member.

A delivery system and method for percutaneous aortic valve (PAV) replacement and apparatus used therein. A temporary aortic valve including a reversibly expandable occluder surrounds a central catheter mechanism. The temporary valve is positioned within the ascending aorta, just above and downstream from the coronary ostia. The occluder is configured such that, when fully expanded against the aortic wall, gaps are left that promote continuous coronary perfusion during the cardiac cycle. The temporary valve substitutes for the function of the native aortic valve during its replacement. The native aortic valve is next dilated, and then ablated through deployment of low profile, elongated, sequentially delivered stents. The stent(s) displace the native tissues and remain within the aortic annulus to receive and provide a structure for retaining the PAV. The PAV is delivered, positioned and deployed within the stent(s) at the aortic annulus with precision and relative ease.

The present technology is generally directed to delivery systems for medical implants, such as electrode assemblies for stimulating heart tissue. In some embodiments, a delivery system for a medical implant includes an elongate sheath having a distal portion and a balloon coupled to the distal portion of the sheath. The delivery system can further include a fluid circuit configured to be in fluid communication with the balloon and having a pressure source and a pressure sensor. The pressure source can move the balloon between an inflated configuration and a deflated configuration, and the pressure sensor can sense a pressure within the balloon. The sensed pressure can be monitored to determine (i) that the balloon is in contact with heart tissue of a heart, (ii), a motion profile of the heart tissue, and/or (iii) blood flow characteristics within the heart.

A non-invasive system for concurrent monitoring cardiac, respiration activity and other body motions from a patent support device integrated with biometric sensors. Such system can also predicate a motion state to enable/disable a medical imaging device or radiotherapy device during cancer and/or cardiac arrhythmias treatment.

A surgical instrument navigation system is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient. The surgical instrument navigation system includes: a surgical instrument; an imaging device which is operable to capture scan data representative of an internal region of interest within a given patient; a tracking subsystem that employs electro-magnetic sensing to capture in real-time position data indicative of the position of the surgical instrument; a data processor which is operable to render a volumetric perspective image of the internal region of interest from a point of view of the surgical instrument; and a display which is operable to display the volumetric perspective image of the patient.
