Jun 12, 2008, 01:00 ET from XTENT, Inc.

    MENLO PARK, Calif., June 12 /PRNewswire-FirstCall/ -- XTENT, Inc.
 (Nasdaq:   XTNT) today announced a progress update regarding its application
 to the designated European Notified Body for CE Mark approval of its Custom
 NX(R) DES System. XTENT's European Notified Body confirmed that recently
 presented six-month follow up results from the CUSTOM III study will be
 incorporated by the Drug Agency, which reviews the drug formulation
 submission of XTENT's CE Mark application, into its current review cycle.
 XTENT's CE Mark application, which included two components, the XTENT
 design dossier and the drug formulation submission, was filed in December
     "Given the positive results of CUSTOM III, we are encouraged that the
 Drug Agency, which has already approved Biolimus A9(R) and PLA combinations
 on two other DES platforms, has accepted the additional data for review.
 This, we believe strengthens an already robust submission for our Custom NX
 System," said Gregory D. Casciaro, XTENT's President and CEO. The company
 anticipates a response from its European Notified Body regarding its CE
 Mark application this summer.
     About the Custom NX(R) DES System
     Custom NX is designed to enable a more personalized approach to the

 features a proprietary modular stent design that consists of multiple 6 mm
 cobalt chromium segments coated with Biolimus A9(R) and PLA, a
 biodegradable drug carrier. The Custom NX delivery system enables the stent
 length to be adjusted in 6mm increments and allows for the placement of up
 to 60mm of stent at one or more locations. The Custom NX DES System has not
 been approved for sale by any regulatory authority.
