The sample was not returned.The lot number is unknown; therefore, the device history record could not be reviewed.The instructions for use which accompanies all devices currently addresses potential risks associated with surgically implanted materials.The instructions for use states in the adverse events: observed adverse events: the tegress¿ urethral implant clinical trial involved 374 tegress¿ implant treatment injections in 174 subjects (mean follow-up of approximately 14 months).There were no deaths among study patients.The following table lists the treatment related adverse events reported during the clinical study (incidence >2%).Treatment related events are those events that were deemed to be related to either the device or the procedure.All genitourinary events were classified as treatment related.Number (%) subjects reporting treatment related adverse events event category tegress¿ implant (n=174) urinary tract infection (uti) 50 (29%) delayed voiding 32 (18%) dysuria 31 (18%) exposed material 28 (16%) urinary urgency 24 (14%) urinary frequency 22 (13%) genitourinary (infection, tenderness) 20 (11%) hematuria 19 (11%) urge incontinence 16 ( 9%) worsening of incontinence (onset of urge) 14 ( 8%) outlet obstruction 13 (7%) pain at injection site 13 (7%) pelvic pain 13 (7%) yeast infection 12 (7%) leakage of urine/stress incontinence 9 (5%) bulking material injected into bladder 7 (4%) fatigue 3 (2%) abnormal urinalysis 3 (2%) bladder fullness 3 (2%) nocturia 3 (2%) pelvic heaviness 3 (2%) uterine fibroids 3 (2%) other (<2%)* 38 (n/a).¿other¿ treatment related adverse events in tegress¿ urethral implant patients, occurring at frequencies of < 2%, were as follows (listed alphabetically): abdominal upset, bladder spasms, bladder stones, body aches, burning pain, cold and shivering, cyst, cystitis, feeling of decreased sensation with urination, feeling of bladder not emptying, felt faint during bulking injection, fever, garlic odor, genital pain, kidney stones, labia with erythema, lower back pain, medicinal smell to urine, nausea, partial urinary retention due to dementia, pyuria, removal of tegress¿ implant, urethral burning sensation, urethral irritation, urethral redness, urethral soreness, urethral spasm, vaginal bleeding, and vulvar burning.Most treatment related adverse events occurred within 24 hours of treatment and subsequently resolved within 30 days.At the time of database closure, 92% of treatment related adverse events were resolved.The following events were persistent or resolution was unconfirmed at the time of database closure (the number of events is shown in parentheses): urge incontinence (6); leakage of urine/stress incontinence (5); worsening of incontinence (onset of urge) (5); exposed material (4); uterine fibroids (3); urinary tract infection (2); urinary frequency (2); urinary urgency (2) and one event each of genitourinary (infection/tenderness), kidney stones, nocturia, pelvic pain, urethral redness, and tegress¿ implant removal.Of the treatment related adverse events, 39% were classified as mild, 58% were classified as moderate, and 3% were classified as severe.The severe treatment related adverse events included: bladder spasms, bladder stones, bulking material injected into the bladder, delayed voiding, exposed bulking material, hematuria, pelvic pain, urge incontinence, and urinary frequency.The clinical study consisted of a pilot or feasibility phase (n=28), followed by the expanded study phase (n=146).There was higher overall rate of genitourinary adverse events in the feasibility phase of the study than in the expanded phase.In particular, the rate of ¿exposed material¿ was higher (32% vs.13%).This reduction in the rate of exposed material was achieved as a result of modifications to the tegress¿ implant injection instructions and investigator training.During the course of the clinical investigation (both study phases), 28 subjects (16%) receiving tegress¿ urethral implant treatment experienced exposed bulking material in the urethral mucosa.Patients experiencing exposed material often reported other events, particularly dysuria, delayed voiding, urinary tract infection, hematuria, urinary frequency, and urinary urgency.Exposed tegress¿ implant material was associated with shallow placement and injection too proximal to the bladder neck.Over time, the urethra healed spontaneously as the mucosal surface re-epithelialized.The physician may choose to remove exposed material cystoscopically with graspers or forceps to facilitate healing.The majority of patients were injected via the transurethral approach, while a small proportion of patients were injected periurethrally.There were significantly more adverse events among tegress¿ implant patients treated periurethrally; as a result, the tegress¿ urethral implant instructions for use are limited to transurethral administration.Potential adverse events: although not reported in the clinical study, other potential adverse events which may occur include erosion, erythema, embolic phenomena, and vascular occlusion.(b)(4).No sample received.

The patient's attorney alleged a deficiency against the device.It was reported in the patient's medical records that as a result of having the product implanted, the patient has experienced infection, abdominal/pelvic pain, painful intercourse, vaginal scarring, recurrence, suprapubic ventral hernia, abdominal pain, bowel obstruction, periumbilical pain, blood loss, grade three cystocele (prolapse), rectocele, hematuria, cystitis (inflammation), urinary tract infection, collagen coming out into bladder (foreign body in patient) and non-surgical and additional surgical interventions.
