    摘要: A catheter introducer system for endoscopy is disclosed which includes a steering section and a propulsion section located near the end of the catheter that is introduced in a body cavity, and a non-collapsible sheath defining a working channel. The propulsion section is designed to pull the rest of the catheter inside the body cavity, so there is no need to push the catheter along. The propulsion section further includes gripping members, such as inflatable balloons, that are axially movable relative to the catheter. The catheter can thus be made very flexible in bending, and a larger diameter catheter can be used without discomfort to the patient.

    摘要: A flexible composite tube for medical applications is described. The tube has the ability to transmit a torque and to resist compression, tension, and kinking. The tube is also very flexible in bending, and has a small wall thickness. Different layers are used to obtain the desired properties. Torsional stiffness is obtained by embedding a braid in an elastomeric material. Resistance to kinks and to compression and tension is obtained by placing coils radially inward or outward of the braid. Smooth plastic layers are used to seal the assembly, and facilitate sliding in a body cavity.

    摘要: A self propelling catheter introducer system for exploring a body cavity is disclosed which includes a flexible tubular catheter, a propulsion section and a steering section located near the end of the catheter that is introduced in a body cavity. The propulsion section includes a flexible everting tube designed to push the catheter from inside the body cavity. The catheter can thus be made very flexible in bending, and a larger diameter catheter can be used without discomfort to the patient.

    摘要: An actuator is used in a surgical simulation system that simulates the catheterization of cardiac or peripheral vasculature. The simulation system provides haptic feedback to a user of a catheter or similar elongated object coupled to the system. The actuator includes sensors that generate sense signals indicative of axial translation and rotation of the object by the user. The sense signals are provided to a workstation executing a simulation program. In response to the sense signals, the workstation calculates axial forces and torques to be applied to the object as haptic feedback to the user, and generates drive signals representing the calculated axial forces and torques. Mechanisms within the actuator respond to the drive signals by applying corresponding axial force and torque to a rigid tube that is mechanically coupled to the object. One embodiment of the actuator includes a carriage assembly for holding the rigid tube between a pair of opposed pinch wheels. The carriage assembly rotates to rotate the object about its longitudinal axis, and the pinch wheels rotate to translate the object axially. Another actuator embodiment includes a first bearing mounted on a rotary actuator and a second bearing mounted on a sliding linear actuator. The rigid tube has a square cross section for secure engagement by the second actuator. The linear actuator grips the tube and allows it to freely rotate about its longitudinal axis.

    摘要: A catheter introducer system for endoscopy is disclosed which includes a steering section and a propulsion section located near the end of the catheter that is introduced in body cavity, and a non-collapsible sheath defining a working channel, disposed inside the catheter, extending substantially from the proximate to the distal end and maintaining a substantially circular cross-section even when bent along an axis. The propulsion section is designed to pull the rest of the catheter inside the body cavity, so there is no need to push the catheter along. The catheter can thus be made very flexible in bending, and a larger diameter catheter can be used without discomfort to the patient.

    摘要: A catheter introducer system for endoscopy includes a steering section and a propulsion section located near the end of the catheter that is introduced in a body cavity. The propulsion section is designed to pull the rest of the catheter inside the body cavity, so there is no need to push the catheter along. The propulsion section includes a distal and proximal gripper portion, each of which includes a suction ring extending circumferentially around the catheter. Each suction ring can include a plurality of suction holes disposed either on a recessed portion of the suction ring or on a portion surrounded by a peripheral ridge extending above the outer surface of the suction ring. The suction ring can also include an inflatable member for urging tissue against the perimeter of the suction holes.
