Dual short throw advancer/retractor
View Patent ↗A dual throw advancer/retractor has a pair of finger rings that can independently advance or retract a medical device into a catheter. The advancer/retractor has a body and a channel wherein each finger ring moves independently in the channel. One end of the medical device is preferably secured to the body and forms a loop within the finger ring such that movement of the finger ring creates an amplified movement in the medical device.
1. An advancer/retractor, comprising:
a handle body having, at least, a first medical device and a second medical device secured thereto;
a first grip connected to the handle body and to the first medical device, wherein movement of the first grip causes an amplified movement of the first medical device; and
a second grip connected to the handle body and to the second medical device, wherein movement of the second grip causes an amplified movement of the second medical device, wherein the first grip includes a first pulley around which the first medical device is looped and the second grip includes a second pulley around which the second medical device is looped.
2. The advancer/retractor of claim 1 , wherein the first and the second grips are independently advanced or retracted.
3. An advancer/retractor, comprising:
a handle body having, at least, a first medical device and a second medical device secured thereto;
a first grip connected to the handle body and to the first medical device, wherein movement of the first grip causes an amplified movement of the first medical device; and
a second grip connected to the handle body and to the second medical device, wherein movement of the second grip causes an amplified movement of the second medical device, wherein the first grip includes a finger ring which forms a first pulley and the second grip includes a finger ring which forms a second pulley.
4. An advancer/retractor, comprising:
a handle body having, at least, a first medical device and a second medical device secured thereto;
a first grip connected to the handle body and to the first medical device, wherein movement of the first grip causes an amplified movement of the first medical device; and
a second grip connected to the handle body and to the second medical device, wherein movement of the second grip causes an amplified movement of the second medical device, further comprising a catheter coupled to the handle body, wherein the first medical device passes through the catheter and is advanced and retracted into and out of the catheter with movement of the first grip and the second medical device passes through the catheter and is advanced and retracted into and out of the catheter with movement of the second grip.
5. An advancer/retractor, comprising:
a handle body having, at least, a first medical device and a second medical device secured thereto;
a first grip connected to the handle body and to the first medical device, wherein movement of the first grip causes an amplified movement of the first medical device; and
a second grip connected to the handle body and to the second medical device, wherein movement of the second grip causes an amplified movement of the second medical device, wherein the first medical device includes a flexible portion which forms a loop at the first grip and the second medical device includes a flexible portion which forms a loop at the second grip.
