  • Patent number: 7377909
    Abstract: A connection system for connecting a hemostasis valve to a splittable sheath is disclosed. The connection system includes an adapter fitting having a shaft defining a lumen. The shaft has a proximal end and a distal end. On an external surface of the proximal end of the shaft, threading is provided for engagement with the hemostasis valve. A cannula portion defines the distal end of the shaft for interfacing with a splittable sheath. A wedge is disposed on an external surface of the cannula portion for interfacing with a weakened portion of the splittable sheath. A sliding connector is disposed about the shaft for engagement with the splittable sheath. Upon a first level of engagement between the sliding connector and the splittable sheath, a fluid-tight seal is created. Upon a second level of engagement between the sliding connector and the splittable sheath, the wedge initiates separation of the splittable sheath.

  • Patent number: 5322509
    Abstract: A catheter for cardiac procedures includes a generally C-shaped distal end which roughly conforms to the shape of an aortic arch. The catheter is made of a flexible material and includes a distal portion having a proximal section connected to an intermediate section at approximately 135 degrees. The distal most section attached to the intermediate section is generally perpendicular to the intermediate section and consists of a double or reverse curve. The structure allows the catheter to be utilized to enter either left or right ostia without catheter exchange by rotation of the catheter around its axis.
