An introducer assembly includes an elongate sheath sized for insertion into a blood vessel of a patient and a hub. The hub can be coupled to a proximal portion of the sheath and can include a first hub portion and a second hub portion. The hub can include various features to facilitate breaking apart or separating the introducer assembly from a patient. For example, the first hub portion can have a first notch which can facilitate breaking, splitting, or fracturing the hub. The second hub portion can partially surround the first hub portion and can include two wings and an opening disposed above the first notch. The first hub portion can be formed from a first material and second hub portion can be formed from a second material. In some embodiments, the second material can be stiffer than the first material to facilitate fracturing the hub.

Introducer sheath having a multi-layer hub

A sheath assembly for the insertion of a percutaneous pump includes a tubular sheath body dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall having a proximal end portion, a distal end portion, a longitudinal axis, an outer surface, an inner surface defining a first lumen substantially parallel to the longitudinal axis, and a second lumen disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.

Dual lumen sheath for arterial access

A robotic catheter procedure system includes a bedside system that has a percutaneous device, and an actuating mechanism configured to engage and to impart movement to the percutaneous device. The system also includes a workstation coupled to the bedside system. The workstation includes a user interface configured to receive a user input, ma display device configured to display an image, a control system operatively coupled to the user interface and the actuating mechanism. The control system is configured to generate a control signal and the actuating mechanism causes movement of the percutaneous device in response to the control signal. The control system is configured to slow movement of the percutaneous device via the actuating mechanism as an identified point on the percutaneous device approaches a structure requiring a change in direction of the percutaneous device.

Robotic catheter system with variable speed control

A robotic catheter procedure system for performing a procedure to treat a vascular lesion including a bedside system and a remote workstation is provided. The bedside system includes a first percutaneous device including an end section, the end section structured to allow the first percutaneous device to create a bore through the vascular lesion. The bedside system includes a second percutaneous device. The bedside system also includes a first actuating mechanism configured to engage and to impart movement to the first percutaneous device and a second actuating mechanism configured to engage and to impart movement to the second percutaneous device. The remote workstation includes a user interface and a control system operatively coupled to the user interface and to the bedside system. The control system controlling the first actuating mechanism to cause movement of the first percutaneous device to create a bore through the lesion and the second actuating mechanism to cause movement of the second percutaneous device through the bore created by the first percutaneous device.

Occlusion traversal robotic catheter system

A robotic catheter procedure system is provided. The robotic catheter procedure system includes a bedside system and a remote workstation. The bedside system includes a percutaneous device and a drive mechanism configured to engage and to impart an axial force to the percutaneous device and to advance and retract the percutaneous device. The bedside system includes an actuator providing torque to the drive mechanism to impart the axial force to the percutaneous device, and the torque provided by the actuator is variable. The remote workstation includes a user interface configured to receive a first user input and a control system operatively coupled to the user interface. The control system is configured to communicate a control signal to the actuator. The control signal is based upon the first user input and a second input, and the actuator provides torque to the drive mechanism in response to the control signal.

Robotic catheter system with variable drive mechanism

A robotic catheter procedure system includes a bedside system and a workstation. The bedside system includes an actuating mechanism configured to engage and to impart movement to a percutaneous device. The workstation includes a user interface and a control system configured to be operatively coupled to the user interface, the bedside system, and a medical imaging system. The control system is responsive to a first input and to a second input, and the user interface receives the second input from a user. The control system is configured to generate a first control signal to the medical imaging system based on the first input, and the medical imaging system captures at least one image in response to the first control signal. The control system is configured to generate a second control signal to the actuating mechanism based on the second input, and the actuating mechanism causes movement of the percutaneous device in response to the second control signal. The first input is indicative of upcoming percutaneous device movement.

Robotic catheter system including imaging system control

A robotic catheter procedure system for performing a procedure including a bedside system and a remote workstation is provided. The bedside system includes a first percutaneous device and a second percutaneous device. The bedside system also includes a first actuating mechanism configured to engage and to impart movement to the first percutaneous device and a second actuating mechanism configured to engage and to impart movement to the second percutaneous device. The remote workstation includes a user interface and a control system operatively coupled to the user interface and to the bedside system. The control system controlling the first actuating mechanism to cause movement of the first percutaneous device to create a bore through the lesion and the second actuating mechanism to cause movement of the second percutaneous device through the bore created by the first percutaneous device.

A robotic system includes a bedside system comprising an axial drive mechanism and a rotational drive mechanism. An engagement mechanism engages and disengages a percutaneous device from at least one of the axial drive mechanism and rotational drive mechanism. A remote work station includes a user interface and a control system operatively coupled to the user interface. The control system is configured to communicate a control signal to the engagement mechanism to engage and disengage the percutaneous device from one of the axial drive mechanism and rotational drive mechanism.

Variable drive force apparatus and method for robotic catheter system

Hemostasis valves and hemostasis valve assemblies can be coupled to a proximal end of an introducer sheath to prevent blood loss through the proximal end of the introducer sheath. Some hemostasis valve assemblies may include an elastomeric member with a variable-width channel that is designed to form a liquid-tight seal over elongate members of different diameter or a single elongate member of variable diameter.
