I, Fred P. Lampropoulos, certify that:

         1.       I have  reviewed this  quarterly  report on Form 10-Q of Merit
                  Medial Systems, Inc.;

         2.       Based on my knowledge,  this quarterly report does not contain
                  any untrue  statement  of a  material  fact or omit to state a
                  material fact necessary to make the statements  made, in light
                  of the  circumstances  under which such  statements were made,
                  not  misleading  with  respect to the  period  covered by this
                  report;

         3.       Based on my  knowledge,  the financial  statements,  and other
                  financial  information  included  in  this  quarterly  report,
                  fairly   present  in  all  material   respects  the  financial
                  condition,  results  of  operations  and  cash  flows  of  the
                  registrant  as of,  and for,  the  periods  presented  in this
                  report;

         4.       The  registrant's  other  certifying   officer(s)  and  I  are
                  responsible  for  establishing   and  maintaining   disclosure
                  controls  and  procedures  (as defined in  Exchange  Act Rules
                  13a-15(e) and 15d-15(e)) for the registrant and we have:

                  a) Designed such disclosure controls and procedures, or caused
                  such  disclosure  controls and procedures to be designed under
                  our supervision,  to ensure that material information relating
                  to the registrant, including its consolidated subsidiaries, is
                  made known to us by others within those entities, particularly
                  during the period in which this report is being prepared;

                  b) Evaluated the effectiveness of the registrant's  disclosure
                  controls  and  procedures  and  presented  in this  report our
                  conclusions about the effectiveness of the disclosure controls
                  and  procedures,  as of the end of the period  covered by this
                  report based on such evaluation; and

                  c)  Disclosed  in this  report any change in the  registrant's
                  internal control over financial reporting that occurred during
                  the registrant's  most recent fiscal quarter (the registrant's
                  fourth  fiscal  quarter in the case of an annual  report) that
                  has materially affected, or is reasonably likely to materially
                  affect,  the  registrant's  internal  control  over  financial
                  reporting; and

         5.       The  registrant's  other  certifying  officer(s)  and  I  have
                  disclosed,  based on our most  recent  evaluation  of internal
                  control over financial reporting, to the registrant's auditors
                  and the audit committee of the registrant's board of directors
                  (or persons performing the equivalent function):

                                        1


                  a) All significant deficiencies and material weaknesses in the
                  design  or  operation  of  internal   control  over  financial
                  reporting which are reasonably  likely to adversely affect the
                  registrant's ability to record, process,  summarize and report
                  financial information; and

                  b)  Any  fraud,   whether  or  not  material,   that  involves
                  management or other  employees who have a significant  role in
                  the registrant's internal control over financial reporting.
