What does a 2-time whitewater slalom world champion have to do with solving obesity, GERD, and type 2 diabetes? Everything!

In this week’s episode of Pod of Inquiry, Dr. Stephen Barrett sits down with Fritz Haller—world champion athlete, Olympic coach, and CEO of Endolastic—to discuss a groundbreaking endoscopic technology that may transform the future of metabolic and gastrointestinal disease treatment. (Breakthrough for GERD & Obesity)

What You’ll Learn in This Episode:

  • How a simple “rubber band gun” mechanism may outperform billion-dollar weight-loss drugs
  • The gut-brain pathway that controls metabolism—and how to reset it
  • Fritz Haller’s journey from Olympic competition to medical innovation
  •  The science behind endoluminal tissue regeneration
  • Why this approach may reshape treatment for GERD, obesity, fatty liver, and diabetes

While GLP-1 drugs like Ozempic and Wegovy see 70% dropout rates, and traditional bariatric surgery often leads to weight regain, this regenerative approach aims to restore gut-brain communication, not bypass it.

This is not another fad or miracle claim—it’s peer-reviewed research with hundreds of patients already showing life-changing results and FDA trials underway.
Fritz Haller’s story proves that breakthroughs often come from unexpected places—and bold thinkers who refuse to settle.

01:19 – Fritz’s Background

  • Born in Baltimore, one of four children
  • Father was Chief of Pediatric Surgery at Johns Hopkins (worked with Dr. Blalock on early heart surgery)
  • Mother was also a surgeon
  • Fritz and his brother ran away from medicine initially

01:51 – Whitewater Career Begins

  • Non-competitive camp with reward-based progression system
  • At age 12-13, watched 1972 Munich Olympics video and decided to become an Olympian

04:29 – Olympic Journey & Disappointments

  • Made the US team with his brother in the two-man whitewater slalom event
  • Won two world championships

04:32 – 1980 Moscow Olympics Boycott

  • US boycotted 1980 Moscow Olympics (Jimmy Carter’s political decision)
  • Team had 113 world champions across various sports
  • Devastating blow to athletes’ dreams

06:28 – 1983 World Championship & 1984 LA Olympics

  • Won world championships in 1983
  • 1984 LA Olympics compromised by Eastern Bloc boycott (East Germans didn’t compete)
  • Main competition was East Germans, who weren’t there

08:19 – Coaching Career

  • Hired to coach US team in 1988 (quadrennium)
  • Coached a gold medal in two-man boat at Barcelona 1992
  • Reflects that coaching others was more fulfilling than individual accomplishment

10:00 – Transition to Medical Devices

  • Met wife in Chile while training with US team
  • Got into alternative pharmaceutical and medicine field
  • Called Cook Medical about a product, ended up getting hired as business director in Santiago

13:00 – Cook Medical & Endoscopy

  • Cook Medical made endoscopic accessories
  • Learned about endoscopic devices and moved up through product management
  • Cook Endoscopy is in Winston-Salem, North Carolina

14:22 – Multi-Band Ligator Technology

  • Explains the multi-band ligator device for bleeding varices (end-stage liver disease)
  • Device uses latex/isomeric bands to ligate engorged blood vessels in esophagus
  • Like “docking a dog’s tail” – creates pressure necrosis

15:23 – Seeing Innovation Differently

  • Fritz saw the device as more than a commodity
  • Drew inspiration from sports innovations (small changes making big differences)
  • References Dick Fosbury’s “Fosbury Flop” in high jump (1968 Olympics)

17:46 – Sports Innovation Examples

  • Pablo Morales and David Berkoff’s underwater dolphin kick in backstroke
  • Swimming rule changes: now must surface by 15 meters (red buoy)
  • Fritz’s philosophy: stack small innovations for big results

19:54 – Barrett’s Esophagus Treatment

  • Off-label use of banding for Barrett’s esophagus (pre-cancerous condition from GERD)
  • Endoscopic Mucosal Resection (EMR) technique developed
  • “Cookie cutter” approach to remove pre-cancerous tissue

25:00 – Tissue Layers & EMR Technique

  • Mucosal layer → submucosal layer → muscle layer
  • Band keeps tissue separate from muscle to prevent perforation
  • Shaking the band ensures no muscle involvement
  • T-cell regulated regeneration by location

27:00 – The “Fosbury Flop” Moment

  • Dr. Ahmad Rahmani at Indiana University (now in Dubai)
  • Romani’s innovation: using the band to tighten the lower esophageal sphincter for GERD
  • Retroflex scope technique to plicate the loose sphincter

30:00 – Tissue Regeneration Discovery

  • Band creates pressure necrosis, tissue dies and falls off in 3-7 days
  • New tissue grows back tighter due to fibrosis
  • T-cell regulated by location – tissue “knows” where to regenerate
  • Same principle as EMR: clean tissue grows back

31:16 – Starting Intelligent Endoscopy

  • Fritz couldn’t move Cook Medical (large company inertia)
  • Started his own company: Intelligent Endoscopy
  • Developed Smart Band (sold to Steris Corporation in 2020)

32:27 – Long Journey

  • Dream started in 2014 – over a decade of work
  • Fritz was an “amateur athlete” – used to putting in massive effort

33:30 – Personal Reflection on Aging

  • After selling company in 2020, Fritz felt skills degrading at age 63
  • Energy, concentration, attention to detail declining
  • Realized by 65 that decision-making and experience were still valuable
  • Now 65 and not thinking about stopping

36:39 – GERD Clinical Results

  • First four clinical patients at Indiana University (with IRB)
  • All went off PPIs (proton pump inhibitors) – 100% success
  • Bravo probe scores showed no GERD symptoms
  • Followed for two years with sustained results
  • Cohort expanded to ~700 patients

38:10 – FDA Status

  • NO FDA clearance yet for GERD or obesity indications
  • Pre-submission 510(K) meeting held last Tuesday
  • 3-month delay due to government shutdown

39:14 – Timeline

  • General ligation label expected Q1 2026
  • Off-label use possible starting then
  • FDA-mandated safety and effectiveness trial will take 12 months
  • Final clearance expected Q4 2027

40:08 – Obesity & Gastric Bypass

  • Current gold standard: Laparoscopic Sleeve Gastrectomy (LSG)
  • Cuts off greater curve of stomach, creates narrow flexible tube
  • Changes hormonal interactions (GLP-1, etc.)
  • Problem: 77% of patients regain weight within 3-5 years

43:24 – Obesity & Fatty Liver Disease

  • Obesity pandemic linked to fatty liver disease (Nash/NAFLD)
  • Replacing cirrhosis from alcohol
  • High fructose corn syrup is a major culprit
  • Key stat: 5-7% total weight loss reduces fatty liver disease risk by 55%

45:10 – Less Invasive Advantage

  • Fritz’s technology will be less invasive than traditional gastric bypass
  • Comparison to arthroscopic knee surgery vs. open procedures
  • Expects massive uptake due to lower barrier to entry

47:42 – GLP-1 Inhibitors (Ozempic, etc.)

  • Had “absolutely nothing” impact on worldwide obesity pandemic
  • Strong marketing effect in US, but Europe barely knows about them
  • 70% of Americans on GLP-1s quit within one year
  • Reasons: cost, adverse events, discomfort

50:00 – Restoring Normal Function

  • Endo Band restores normal morphology vs. other interventions
  • Only surgery that changes entire metabolism and reverses type 2 diabetes

51:33 – Gastric Bypass Procedure Explained

  • Remove stomach entirely
  • Pull duodenum up to esophagus, create pouch
  • Very invasive and extreme
  • Requires lifelong medications, iron deficiency risks
  • Notable: Reverses type 2 diabetes 100%

52:57 – The Gut Brain Discovery

  • 15 cm of duodenum (between ampulla of Vater and ligament of Treitz) = “gut brain”
  • Where GLP-1 and metabolic signaling occurs
  • Endogastric Solutions tried stent approach ~20 years ago (still seeking FDA approval)

55:00 – Duodenal Tissue Regeneration

  • Fractal Health ablated duodenal tissue with steam
  • Dropped HbA1c by 2 full points within 2 weeks
  • Concept: Replace dysfunctional mucosal layer with fresh tissue
  • Fritz’s approach: use “rubber band gun” to target duodenal mucosa
  • T-cell regulated regeneration brings back functioning gut-brain tissue

59:00 – Availability Timeline

  • US market under FDA clearance: Q4 2027
  • Looking for investors and physicians interested in the technology
