Moreover, subdural grid and strip electrocorticography (ECoG) electrodes with stainless-steel contacts (diameter: 4 mm) were implanted in the frontal, temporal and parietal lobe of several patients.
Stainless-steel bipolar electrodes (model MS303/2, Plastics One, Roanoke, VA), cut to a length of 11 mm, were implanted in the posterior lateral hypothalamus (AP −0.5 mm from bregma, ML ±1.7 mm, DV −8.3 mm from dura, with the incisor bar 5 mm above the interaural line (Pellegrino et al, 1979)).
Porous cylindrical specimens 8 × 10 mm were implanted in the lateral aspect of the tibia of 13 patients (mean age 54 years), during osteotomy surgery for the treatment of medial compartment osteoarthritis of the knee.
Titanium screws with 3.5 mm diameter and 8 mm length, as well as titanium flat sheets with size 4 mm×8 mm×0.3 mm, were implanted into the epithelial mantle pearl sacs of a fresh water bivalve (Hyriopsis cumingii Lea) by replacing the pearls.
Mice were anesthetized with subcutaneous injection of 0.05 ml Zoletil® mix (Virbac, Carros Cedex, France) before HER-2-positive breast cancer (SKBR-3) tumor fragments from xenografted animals (1 × 1 × 1 mm) were implanted subcutaneously.
In some experiments additional bipolar electrodes staggered vertically by 1.5 2.00 mm were implanted in frontal cortex (AP: +2.6 mm, ML: ±0.5 mm, DV deep pole): −1.5 2.0 mm) [47], [60], [61].
A porous scaffold fabricated with ∼80% porosity and pore diameters ranging from 45 to 150 mm was implanted in a critical-sized cranial defect in rats.
A 26-gauge cannula of polyethylene tubing (PE-10: inner diameter 0.28 mm, outer diameter 0.61 mm) was implanted into the lateral cerebral ventricle (1 mm caudal to Bregma, 2 mm lateral to the mid-sagittal sinus, and 4 mm ventral to dura) and secured to the skull with surgical glue.
Using a trocar, a small tumour fragment (1 mm) was implanted into the hole made in the skull.
A stainless steel guide cannula (22 gauge, 0.7-mm outer diameter, length 13 mm) was implanted above the right lateral ventricle before the electrodes were implanted ipsilaterally.
The middle portion of left anterior descending artery (Segment 7) showed 90%% stenosis, and a bare-metal stent (MULTI-LINK VISION, 2.75 × 18 mm) was implanted.
