Nice background, title bar and headings
3
Too much white space between headings and text in
each section
Mission statement could be one sentence needs
emphasis
Increase white space to the left of the
text/bullets in this vertical white panel.
Bullets and corresponding text should be closer
together.
4
Punctuate sentences
Cut Currently emphasize with bold/color
There is no standardized . . .
limited how??
5
Different size or bold font to emphasize the
difference between regular text and figure caption
Label image directly and cut caption
What about the other prototypes?
6
Word choice Dimensions?
Design doesnt address this issue
Consider placing Design Objectives before your
Solution
7
Show multiple tests for multiple prototypes
Use r2 too many sig. figs.
Tests and results are buried in captions
Separate testing of prototypes
8
Lots of space for something not done
Good spacing of bullets here, but use different
style for sub-bullets
Avoid jargon
Caption font line spacing could be smaller
9
Evidence?
Too many words obscure key point
Is this like in the body?
10
Could use smaller font for Acknowledgments and
References
Bullets are different sizes

• Mission Statement
• We aim to provide the first artificial trachea
  unit that is ready for immediate implantation
  through a single-step surgical procedure.
• Motivation for SpiralAT
• Clinical Significance of Tracheal Replacement
• 90 of primary tracheal cancers are malignant.
• Of the 90,000 new cases/year of cancers in
  nearby throat tissues, 25-50 will develop into
  secondary tracheal cancer.
• Other patients suffer from congenital defects
  and physical trauma.
• Current Approaches Sub-optimal
• Tracheal resection is limited because
  reconstruction after resection is not feasible.
• Radiation is not fully reliable because studies
  show inconsistent outcomes in effectiveness.

• Solution The SpiralAT
• Mechanical Testing
• 3-point bending test

• Future Work
• Biocompatibility Studies in Canines
• Quantitative analysis of skin flap integration
• by measuring cross-sectional area at the most
  stenotic point.
• Qualitative endoscopy of tissue ingrowth and
  dehiscence.
• Conclusion

A) Single Spiral Rice B) Single Spiral DPT
C) Double Spiral DPT
Fig. 6. Post-operative examination of an
artificial trachea in canine throat

• Fig. 1. The three versions of the SpiralAT have
  different structures and are made of different
  materials. Each version consists of 2 components,
  a helical support structure and a shell.

Fig. 2. Simulation of flex/ext using a tennis
ball covered crosshead to distribute the force
across a wide area of the sample
Fig. 3. Single Spiral Rice was the stiffest,
followed by Double Spiral DPT and Single Spiral
DPT. Adding an additional helix to the Single
Spiral DPT increased stiffness. (crosshead
speed20 mm/min, max extension10 mm)
Fig. 4. Simulation of flex/ext lateral bending
using an angled wedge attached to upper crosshead
used to focus compressive force on one side
Fig. 5. Increasing load resulted in elastic
deformation. Double Spiral DPT was stiffer than
Single Spiral DPT. (crosshead speed20 mm/min,
max extension10 mm)
