Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Neurogenic Bladder Urinary Retention Urologic Diseases Device: Connected Catheter Not Applicable

Detailed Description:
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.

Arm Intervention/treatment
Experimental: Connected Catheter Users Device: Connected Catheter
Patients will use the Connected Catheter to empty the bladder during the course of treatment.

Primary Outcome Measures :
  1. Improved bladder management without injury to genito-urinary tract [ Time Frame: 35-40 days ]
    Absence of genito-urinary injury/trauma when using Connected Catheter

  2. Successful Bladder Emptying Using Connected Catheter [ Time Frame: 35-40 days ]
    Successful voiding with Connected Catheter as assessed by Post-Residual Volume (PVR) measurement via ultrasound

  3. Freedom from Symptomatic Urinary Tract Infection (UTI) [ Time Frame: 35-40 days ]
    Successful use of the Connected Catheter without significant increase in UTI.

Ages Eligible for Study:   18 Years to 90 Years   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Gender Based Eligibility:   Yes
Gender Eligibility Description:   Device is currently only designed for use by males.
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  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 Must have stable urinary management history as determined by the investigator


    Must have urodynamic profile suitable for Connected Catheter (including bladder capacity > 200mL without uninhibited bladder contractions)

  3. Subject's lower urinary tract anatomy must fall within the ranges serviceable by the Connected Catheter, as specified in the Investigational Device Instructions for Use (IFU).

Exclusion Criteria:

  1. Active symptomatic Urinary Tract Infection (UTI), as defined in this 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 incontinence (between catheterizations)
  5. Uninhibited bladder contractions and/or Vesicoureteral reflux that is not reliably controlled with medication or alternate therapy (e.g. Botox injections)
  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)

    1. Urinary tract inflammation or neoplasm
    2. Urinary fistula
    3. Bladder diverticulum (outpouching) > 5cm in size
    4. Chronic pyelonephritis (secondary to upper urinary tract infection(s) within past 6 months)
    5. Impaired kidney function or renal failure
    6. Active gross hematuria
    7. Active urethritis
    8. Bladder stones
  7. Dependence on an electro-magnetic medical implant (e.g. cardiac pacemaker or implanted drug pump) or external device
  8. Any unsuitable comorbidities as determined by the investigator or complications related to use of certain medications
  9. Any physical or cognitive impairments that diminish the subject's ability to follow directions or otherwise safely use the Connected Catheter System
  10. Catheter Assessment Tool screening yields unacceptable results
