The Connected Catheter is a fully internal, urethral indwelling urinary prosthesis designed for improved bladder management in males with urinary retention disorders requiring catheterization. It is a sterile, extended-use device that resides fully internally to the male lower urinary tract for an intended use life of up to 7 days per catheter.


Spinal Singularity has developed the Connected Catheter System to address several drawbacks of urinary catheters. The Connected Catheter is fully internal, indwelling urinary prosthesis designed for improved bladder management in males with urinary retention disorders requiring catheterization. Each subject will use the Connected Catheter for up to 35-40 days. This includes five device exchange appointments. The appointments are spaced 7 days apart and at each appointment the catheter will be replaced with a new one. Additionally, weekly follow-up will occur for 14 days following the final appointment after the subject discontinues use of study device and reverts to his original catheter.

You can join if…

Open to males ages 18 years and up

  1. Males age ≥ 18 with clinical diagnosis of significant urinary retention
  2. Must be clinically suitable and capable of safely managing bladder using an intermittent voiding or indwelling strategy
  3. Must have stable urinary management history as determined by the investigator OR:
  4. Must have urodynamic profile suitable for Gen 2 Connected Catheter (including bladder capacity > 200mL without uninhibited bladder contractions)
  5. Subject's lower urinary tract anatomy must fall within the ranges serviceable by the Gen 2 Connected Catheter device, as specified in the Investigational Device Instructions for Use (IFU).

You CAN'T join if...

  1. Active symptomatic urinary tract infection, as defined in this clinical investigation protocol (subjects may receive the device after UTI has been treated)
  2. Significant risk profile or recent history of urethral stricture (e.g. stricture within past 90 days)
  3. Significant risk profile or recent history of clinically significant (uncontrolled) autonomic dysreflexia
  4. Significant intermittent urinary incontinence (between catheterizations)
  5. Uninhibited bladder contractions and/or Vesicoureteral reflux that is not reliably controlled with medication or alternate therapy (e.g. Botox injection)
  6. Pre-existing urinary pathologies and/or morphological abnormalities of the lower urinary tract or bladder (assessed during in-depth medical screening, including cystoscopy and urine analysis)
  7. Urinary tract inflammation or neoplasm
  8. Urinary fistula
  9. Bladder diverticulum (outpouching) > 5cm in size
  10. Chronic pyelonephritis (secondary to upper urinary tract infection(s) within past 6 months)
