摘要： A bearing system useful in an intracorporeal device connects an operating head, a rotatable drive shaft and a catheter. The bearing system includes a static member in fixed communication with the distal end of the catheter, an interior shaft that is in rotatable communication with the drive shaft and the operating head, and at least one connecting structure. The static member has at least one opening through which the connecting structure moveably rests against a seat of the interior shaft. The position of the connecting structure within the seat enables the bearing to accept a rotational load of the rotating drive shaft and/or thrust load in the direction of the longitudinal length of the catheter. The connecting structure further retains the internal shaft and static member of the bearing system. A clearance space between the internal shaft and the catheter may permit the interior shaft to tilt relative to the catheter and flexibly orient the operating head at different angles about longitudinal axis of the catheter.

摘要： Interventional catheter assemblies that operate over a guide wire and incorporate guide wire management systems are disclosed. Specifically, a guide wire buffer zone is provided between a proximal end of the interventional catheter and the guide wire clamp that accommodates variable lengths of exposed guide wire in an unrestrained condition when the guide wire is clamped, allowing the distal end of the operating catheter to be advanced and retracted over the distal end of the guide wire without repositioning and reclamping the proximal end of the guide wire. The configuration of the guide wire buffer zone may be adjusted prior to or during an intervention based on the anticipated range of axial motion of the catheter and operating head relative to the guide wire.

摘要： A sealing assembly hinders or prevents air or other fluid from seeping between various components of a medical device by use of a liquid seal. An infusion port is for introducing a sealing liquid to immerse a flood space between a liner that surrounds a torque tube and/or within the torque tube, thereby creating a liquid seal around the torque tube and lubricating the torque tube. The length of the liner and the cross sectional space of the flood space are adjusted to control flow rate. An aspiration port may force suction pressure into a lumen extending along the length of the medical device in a distal direction. The liquid seal also prevents diluting of the suction pressure by stopping ingress of air.

摘要： Intralumenal material removal systems are provided using an advanceable and rotatable cutter assembly designed for differential cutting. The intralumenal material removal system includes a cutter assembly positionable in the body cavity of a mammalian subject. One embodiment of the cutter assembly includes a cutter with blades that are designed and arranged to form an acute blade angle of attack with the matter-to-be-removed. The cutter assembly is axially advanceable by translating the drive shaft and rotatable by rotating the drive shaft. The occlusive material is scraped by the cutter assembly and may be aspirated to remove the material from the body cavity. The cutter assembly may provide aspiration ports positioned between facing surfaces of the blades.

摘要： An ablation assembly (10) is disclosed having a drive assembly (16) positioned in a housing (29) and movable along a longitudinal path of motion within the housing. A tubular shaft (30) extends along a longitudinal axis of the housing between the drive assembly and the end of the housing. The drive assembly includes a turbine (22) coupled to an elastomeric plug (19). An aperture (20) extends longitudinally through the elastomeric plug. A tube (15) is attached to a proximal end of a driveshaft (12) and an ablation instrument (11) is coupled to the distal end of the driveshaft. The tube has a sufficient length to be inserted through the tubular shaft until the proximal end of the tube engages the elastomeric plug with an interference fit within the aperture, thereby coupling the driveshaft to the drive assembly.
