Clinical performance was measured using parameters including but
not limited to dwell time, catheter insertion outcomes, and
adverse event rates. Critical clinical parameters extracted from
these studies met standards set forth in the guidelines for the
State of the Art. There were no unforeseen adverse events or other
high occurrences of adverse events detected in any of the clinical
activities. Medcomp® catheters are subjected to, and must pass,
simulated use testing intended to replicate use 3 times per week
for 12 months as part of device development. The Tesio®/Duo-Jet®
II/Chronic Twinline Catheter passed this testing. Although
Medcomp® catheters contain no materials which degrade over time,
fully functional catheters may be removed for other reasons, such
as intractable infection, change of therapy (such as Renal
replacement (transplant) or use of an arterio-venous
graft/fistula). Published clinical literature does not always
focus on the physical lifetime of a catheter for these reasons. In
the case of the Tesio®/Duo-Jet® II/Chronic Twinline Catheter, 210
catheters had an 87.2 day [95%CI: 71.7 – 102.7 days] duration of
use that has been found in clinical use reported to date. Based on
this information, the Tesio®/Duo-Jet® II/Chronic Twinline Catheter
has a 12-month lifetime; however, the decision to remove and/or
replace the catheter should be based on clinical performance and
need, and not any predetermined point in time.
Summary of Clinical Data Related to the Equivalent Device
Clinical evidence from published literature and PMCF activities
has been generated specific to known and unknown variants of the
subject device. The equivalency rationale in the updated clinical
evaluation report will demonstrate that the clinical evidence
available for these variants is representative of the range of
device variants in the device family. There are no clinical or
biological differences between variants within the subject device
family, and the potential impact of the technical differences will
be rationalized in the updated clinical evaluation report.
Summary of Clinical Data from Pre-Market Investigations (if
applicable)
No pre-market clinical devices were used for the device’s clinical
evaluation.

Source:LTHD Data Collection Survey Report
The Long-Term Hemodialysis Catheter Data Collection Survey was
intended to gather safety and performance outcome information from
sites that purchase Medcomp long-term hemodialysis catheters for
use in EU MDR clinical evaluation. Responses were requested to be
completed by physicians or other site employees with oversight and
direction from a physician. The surveys were distributed globally
to existing Medcomp customers. Responses were collected from
twenty-one sites, spanning nine countries (Colombia, Croatia, El
Salvador, Greece, Italy, Netherlands, Panama, Uruguay, and USA)
across North America, South/Latin America, and Europe. At least
partial data was collected on 78 Tesio® catheter product family
cases totalling at least 1,292 catheter days. Of these 78 cases,
77 were described as 10F and 52cm in length. One case was
described as 12F and 20cm in length. Information was collected on
Insertion Success (96.2%, n=78) and dwell time (215.3 days, 95%
CI: 0 – 492.1, n=6). There was one report of catheter related
blood stream infection (0.77 per 1,000 catheter days), one report
of catheter associated venous thrombus (0.77 per 1,000 catheter
days), and no reports of exit site infection or tunnel infection.
All outcome measures were concluded to be within State of the Art
safety and performance outcome measures from published literature
except for dwell time and catheter associated venous thrombus
rate. This is likely attributable to sample size, as both the
sample mean of dwell time and sample rate of catheter associated
venous thrombus were within State of the Art safety and
performance outcome measures from published literature.

The Medcomp User Survey acquired responses from healthcare
personnel familiar with any number of Medcomp’s product offerings.
28 respondents responded that they or their facility have used
Medcomp long-term hemodialysis catheters, with 3 of those
respondents using the Tesio device. There were no differences in
mean user sentiments within long-term hemodialysis catheters
across State of the Art Performance and Safety Outcome Measures or
between device types relating to safety or performance. The
following data points were collected from users of Medcomp
long-term hemodialysis catheters (n=28):
(Mean Likert Scale Response) Catheters function as intended – 4.8
/ 5
(Mean Likert Scale Response) Packaging allows for aseptic
presentation – 4.8 / 5
(Mean Likert Scale Response) Benefit outweighs the risk – 4.7 / 5
Dwell Time (n=26) – 167 days (95%CI: 130 – 203) The following data
points were collected from users of Medcomp Tesio® catheters
(n=3):
(Mean Likert Scale Response) Catheters function as intended – 4.3
/ 5
(Mean Likert Scale Response) Packaging allows for aseptic
presentation – 4.3 / 5
(Mean Likert Scale Response) Benefit outweighs the risk – 3.6 / 5

The Long-Term Hemodialysis (LTHD) Truveta data analysis assessed
safety and performance outcome information for Medcomp® and
competitor devices present in Truveta Studio. Truveta data comes
from a growing collective of more than 30 health systems that
provide 17% of the daily clinical care across all 50 U.S. states
from 800 hospitals and 20,000 clinics, representing the full
diversity of the United States. The population used for data
analysis was derived utilizing Truveta Studio’s proprietary coding
language (Prose) and unique device identifier (UDI) codes
representing all saleable Medcomp® LTHD devices and LTHD devices
distributed and/or manufactured by other companies. 41 Tesio®
cases inclusive of several variant devices were collected. All
cases were described as 10F and Straight Cases, configurations
(straight), and lengths (36cm, 52cm), representation of 36cm and
52cm length catheters. The following State of the Art safety and
performance outcome measures were observed for Medcomp Tesio®
devices:
Catheter Related Blood Stream Infection – 1.63 per 1,000 catheter
days (95%CI: 0.6 – 3.54)
Catheter Associated Venous Thrombus – 0 per 1,000 catheter days
(95%CI: 0 – 1)
Exit Site Infection – 0.27 per 1,000 catheter days (95%CI: 0.01 –
1.51)
Tunnel Infection – 0 per 1,000 catheter days (95%CI: 0 – 1)
Dwell Time – 63.44 days (95%CI: 32.53 – 94.35) The catheter brand
logistic regression model did not find that any Medcomp® catheter
brands were statistically significantly associated with an
increase of the incidence of CRBSI. The brand agnostic logistic
regression found that pediatric age group (0–19 years), femoral
vein insertion site, catheters that were the fourth or beyond in
sequence for a given patient, split tip designs, and pre-curved
configurations were statistically significantly associated with
the incidence of CRBSI. The Split Cath® III was associated with a
statistically significant decrease in CRBSI incidence in the brand
model (OR: 0.46 95%CI: 0.33 - 0.63), and both shorter catheter
length (<=24cm) and smaller French size (<14.5F) in the
brand agnostic model.
Overall Summary of Clinical Safety and Performance
Upon review of the data across all sources, it is possible to
conclude that the benefits of the subject device, which is
facilitating hemodialysis in patients in whom other therapies or
conservative care are not indicated or desirable as determined by
the physician, outweigh the overall and individual risks when the
device is used as intended by the manufacturer. It is the
manufacturer’s and clinical expert evaluator’s opinion that
activities both complete and ongoing are sufficient to support the
safety, efficacy, and acceptable benefit/risk profile of the
Tesio®/Duo-Jet® II/Chronic Twinline catheters.
