Q

Explain MICC and why that’s different than Abbott’s directional lead.

A

Mulitple Independent Current Control, dimmer switch, can independently control each contact and know where you’re energy is going, abbott is either on or off, if you light up the whole lead you don’t know where energy is being dispersed

Q

V=IR or…

A

I=V/R current=voltage / resistance

26
Q

How is impedance important with regards to MICC?

A

dedicated power source for each of the 8 electrodes on the lead, the Vercise DBS System enables highly accurate targeting to minimize the side effects of unwanted stimulation and maintain therapy over time.

UP/DOWN: increase/decrease, activate/save
PERSON: areas

29
Q

At what temperature will the charger turn off to cool?

A

106 degrees F

30
Q

What is the burr hole cover?

Q

What is the purpose of the burr hole cover cap?

A

designed to protect the lead/clip interface and create a smooth profile over the burr hole

35
Q

What does the horseshoe end of the placement/removal tool do?

A

securely grips the retaining clip, friction fit allows for rotation but maintains final orientation, angled and rotates to provide flexible handling of the clip assembly

38
Q

What does it mean to be in Stimview?

A

you can see the volume of tissue activation, it’s a specific screen within Neural

39
Q

cartesia has active tip so same as a contact, 1.5mm

linear lead has approx 1.1 tip length

50
Q

What connects to a MDT lead or extension? how long?

A

M8, 15cm or 55cm, 15cm in the pocket, connects to MDT extension or 55cm adapter that can connect directly to lead and go into battery

51
Q

What are the specs of the exension?

A

overall length is 55cm, outer diameter 1.35mm, has retention sleeve to secure extension in place so you don’t have to worry about putting a set screw on an active contact

52
Q

What is Med-A, Medical Adhesive?

A

to be used with the Medtronic adapter (M8), hydrophillic, will dry completely inside the body

53
Q

What is the IPG made of?

A

body is titanium, header is epoxy

54
Q

What is the max implant depth of Vercise, and Vercise PC?

A

old vercise: 2cm
Vercise Gevia: 2cm
Vercise PC: no max depth

55
Q

Which lead does not have a retension sleeve and why is this important?

A

Medtronic, may lose energy when connecting to M8 adapter, that ‘s why must use MedA (medical adhesive), a drop of it on the set screw to make sure no energy leaks out, required by DFU

56
Q

What are 2 different ways to secure the burr hole cover according to the DFU?

A
  • use screws as assembled in the retaining clip

- take screws out of the plastic tubular holders, turn 90 degrees then screw screws down

57
Q

Left lead is in what port? What about the right lead? How is this different with Genus?

A

left-C
right-D
Genus is L and R

58
Q

What are the components of the Stimview Screen?

A

connect, configure, program, data, tools, end sesssion

59
Q

What contacts will the doctor want where, in relation to the STN?

A

contacts 2 and 3 in the meat of the STN, on the dorsolateral border, level 3 on the zona inserta

60
Q

What is interleaving?

A

creates 2 settings on a lead where the contacts can be configured with a different amplitude and pulse width, not the same as current steering with MICC
