Abstract: A precision syringe plunger includes a plunger rod and a separately manufactured plunger arm. The plunger rod includes a base formed at a proximal end of the plunger rod and a first interference fit connector formed below the base. The plunger rod is configured to extend longitudinally into a syringe barrel. The plunger arm includes a second interference fit connector formed at a proximal end of the plunger arm. The second interference fit connector is configured to be irreversibly coupled to the first interference fit connector so that the plunger arm extends longitudinally along an outer surface of the syringe barrel. The plunger arm further includes a distally located projection. The projection is configured to receive an applied force that causes an entirety of the syringe plunger to move relative to the syringe barrel so that the plunger rod is actuated through a portion of the syringe barrel.

Abstract: The present invention is directed to balloon catheter having a compression member securing one or more balloon skirts to the catheter shaft. The compression member may be a band or coil that sealing secures the balloon skirt to a catheter shaft. Metallic compression members may be swaged to compress the skirt against the shaft, and thus provide a uniform seal between the balloon skirt and the catheter shaft. The compression members are especially useful when the balloon is formed of a fluoropolymer, such as expanded polytetrafluoroethylene (ePTFE) or polyterafluoroethylene (PTFE).
