Title: Stepper motor logic circuit
Inventor: MAJEWSKI MIROSLAWA A
IPC: H02P8/40
Filed: 1986-01-20
Granted: 1991-04-09
Abstract: ABSTRACT A stepper motor logic circuit for provid-ing stepper motor control signals to the drivers of a stepper motor.  The stepper motor logic circuit receives progammable data from a CPU or manually-initiated back-up data for manually controlling the stepper  motor.   The  logic  circuit  controls  the stepper motor drivers in accordance with variable stepping rate data.  Such data, as provided by the CPU,  includes  clock  rate  data  and control data. The clock rate data written to the logic circuit determines  the  stepping  rate;  the  control  data determines the direction of stepper motor rotation, the  step magnitude  (full  or half  step),  and  the stop  signal.   Preferably,  the  logic  circuit  con-trols  a  pair  of  stepper  motors  independently of each other,  by reading and storing separate clock rate and control data for each motor.

Filed: 1986-12-22
Granted: 1994-01-18
Abstract: Abstract The subject invention relates to a method and apparatus particularly suitable for use in dilating occluded blood vessels.  The apparatus includes a tubular catheter having a balloon member connected to the distal end thereof.  The balloon is initially located in an inverted manner with the free end thereof being connected to a reinversion member.  A tubular sheath is telescopically mounted within the catheter surrounding said balloon member.  In operation, the balloon member is everted by sliding the sheath beyond the distal end of the catheter.  Fluid pressure can be utilized to facilitate eversion and to laterally expand the balloon member after it has been extruded through the occlusion.  The sheath also aids in reinverting the balloon member.
