In addition, the system enables the user to detach him/herself from the board quickly, conveniently, remotely and autonomously, without the need for an automatic board-release system that is not controlled by the user.
Patent CA-2555517-A1 (CA)
Inventor: NOVAK EUGENE J
IPC: A61C1/02
Filed: 1998-09-08
Abstract: A dental handpiece (10) is provided with a drive motor (13), a drive shaft (12) operatively affixed to the drive motor (13) at one end of the drive shaft (12). A dental tool (11) is operatively affixed at the other end of the drive shaft (12). The drive shaft (12) is journaled within an axial displacement bearing (60), such that manipulated rotation of the dental tool (11) causes a first drive shaft section (61) to be axially displaced from and relative to a second drive shaft section (62). The axial displacement bearing (60) is caused to contact a bearing (51) thereby causing the drive shaft (12) to bind due to the frictional forces generated by that contact. This allows sufficient force such that the dental tool (11) can be disengaged from the handpiece (10).

Abstract: A catheter system is described for performing protected angioplasty and stenting of a patient's carotid bifurcation. A self-expanding stent is deployed across a stenosis in the patient's carotid artery. A catheter system that includes a rapid exchange angioplasty catheter with an occlusion balloon catheter positioned through the guidewire lumen is advanced through the guiding catheter to the distal end of the stent. A releasable linking device holds the catheter system together as a unit. The occlusion balloon is inflated within the stent to occlude the carotid artery and to prevent any embolic debris from traveling downstream from the treatment site. The angioplasty balloon is inflated to dilate the stenosis and to complete the expansion of the stent. The angioplasty catheter is withdrawn and any potential embolic debris is aspirated out through the lumen of the guiding catheter. The occlusion balloon is deflated and the catheter system is withdrawn.

Abstract: A medical instrument usable with an ultrasound-endoscope for performing a needle biopsy on a patient's internal body tissues usable at a surgical site not visible to the unaided eye or viewed endoscopically, comprises an elongate tubular member with a hollow needle element connected at its distal end, a sheath member housing said tubular member and needle element, an actuator subassembly with a shifter member operatively connected to elongate tubular member's proximal end, and a distal camming subassembly, said subassembly enabling a rotating motion of said needle member while handle actuator is moved in the forward direction. Upon inserting an ultrasound-endoscope into a patient and locating a mass, the fine needle with sharply pointed spoon shaped distal end is inserted into the mass aided by endoscopic and ultrasonographic guidance. Once in the mass, a camming action is initiated, causing rotation of the fine needle within the mass, resulting in a scooped out core biopsy. This instrument enables the performance of a fine needle aspiration requiring only one or two needle introductions, with a resultant core biopsy substantial enough for diagnostic purposes.
