Subject:

MEDTRONIC QUESTION Steve, regarding registration NR0450D101U issued in '74. This is one that was never billed. The authorization on their materials license is for " Recovery, analysis and storage of explanted nuclear pacemakers.":In their '91 renewal reauest thav etated that Medtronic no longer manufactures or sells nuclear powered cardiac pEcemakers-they only receive, analyze and store explanted pacemakers. l

Dear Ms. Wenell:

This is in reference to Medtronic's October 1988 Report on Model 9000 l nuclear-powered pacemakers (trarismitted by your November 1,1988 letter) and the february 2,1989 telephone Conversation between Tom Hawkinson of Medtronic's staf f and Gary Roles of the Nuclear Regulatory Cornmission's (HRC's) staff. Enclosed for your information is a copy of a document prepared by Mr. Roles sumarizing his discussions with nuclear pacemaker manufacturers.

We are concerned about the apparent discrepancies between Medtronic's October 1988 report and the information provided by Mr. Hawkinson. The report indicates that 658 units have been implanted. This total is the same value reported by Medtronic for some years. Mr. Hawkinson is reported to have stated that "about 1800" units have been implanted, a nurnber almost three times that given in Medtronic's most recent report. Mr. Roles was seeking this information in order to estimate the number of plutonium-238 pacers for which disposal in the United States will be needed, both in the short- and long-term.

Please explain this apparent discrepancy and provide clarifying information.

- If "about 1800" nuclear pacers have been implanted, please submit revised copies of your reports to NRC and explain why erroneous inform 6 tion has been provided to the NRC for a nunber of years. If only 658 units have been implanted, please explain how the 1800 unit value was obtained by Mr. Hawkinson.

Sincerely,
