establishes some key clinical relationships in the emerging
neurostimulation market. Enpath represents an exciting opportunity
that further expands our product and service offerings to the CRM and
neurostimulation marketplaces. This acquisition broadens our market
reach into the vascular segment with the introducer product line as

key steps in our long-term growth strategy."

quarters in 2007 and 2006 (in thousands):

Operating Income                       $(6,351)      $7,127     -189%
Operating Margin                          -8.1%       10.1%

Effective Tax Rate                       NA           34.5%


    The cost of sales percentage decreased from last year primarily
due to favorable mix- and volume- related variances. Sales were higher
in the product lines that typically carry better margins.

    The increase in SG&A expenses is primarily due to higher sales &
marketing expenses and the inclusion of Enpath operations for two
weeks.

    The increase in net RD&E expenses is primarily due to a planned
increase in spending on new development programs.

The other operating expense in the current quarter consists of:

- -- Carson City and Columbia closures/relocations      $ 1.6 million
- -- ECP building expansion                             $ 0.1 million
- -- Asset dispositions and other                       $ 0.3 million


    As a result of $16.1 million of the in-process research and
development write-off not being deductible for tax purposes, the
effective tax rate for 2007 is now expected to be approximately 47.5%.

    Full-Year 2007 Financial Guidance

    We are increasing our sales guidance by $20 million to $25 million
to reflect the inclusion of six months of Enpath sales and increased
sales to CRM customers.

    We are increasing our adjusted guidance by a net of $0.16 per
share based on our strong first half results. This is net of increased
hiring and manpower costs related to investment in development
projects primarily in the areas of MRI compatibility, leads and other
technologies in the range of $0.05 and $0.08.

    Our GAAP EPS guidance for 2007 has been decreased by approximately
$0.62, which includes the write-off of in-process research and
development related to the acquisitions of Biomec and Enpath of $0.72
and $0.04 for other acquisition related adjustments.
