  • Publication number: 20180125758
    Abstract: Methods and systems for a cartridge assembly for use with an injection system are provided. An example cartridge assembly may include an ampule containing a pharmaceutical product that is sealed at a distal end with a pierceable diaphragm. The cartridge assembly may also include a hub comprising a proximal portion defining a cavity that is configured to engage the distal end of the ampule and a piercing member positioned within the cavity. The piercing member may include a fluid pathway between a proximal end portion comprising an opening and a distal end in fluid communication with a distal opening of the hub. The proximal end portion may engage the pierceable diaphragm, and the piercing member may apply a force to the pierceable diaphragm in the inactivated position without penetrating the pierceable diaphragm.

  • Patent number: 8545447
    Abstract: Material transport catheters and methods for their use rely on rotation of an impeller within a catheter body and a clearing element for preventing buildup of materials at the opening of the catheter body. The impeller preferably comprises an inner tube or shaft having a helical rotor fainted over an outer surface thereof. The clearing element may comprise a free end of a structure near the distal end of the catheter body for disrupting clot, wherein the free end of the structure extends into the distal opening of the catheter body to break up materials as the impeller is rotated. Alternatively, the clearing element may comprise a cutting member disposed at the distal opening of the catheter body.

  • Patent number: 7563253
    Abstract: An injector device for a pharmaceutical cartridge. The injector device includes a body defining a space for receiving a pharmaceutical cartridge. One or more retention members are disposed on an outer surface of the body. The injector device further includes a plunger rod having a connection member constructed for connection to a piston associated with a cartridge. The plunger rod has one or more receiving members constructed to cooperatively retain the plunger rod on the body in a first position, and to release the plunger rod from the body when the plunger rod is moved to a second position. The plunger rod further includes a surface for engaging a pharmaceutical cartridge positioned within the body of said injector and for moving a pharmaceutical cartridge distally as the plunger rod is moved from its first position to its second position, thereby activating the cartridge.

  • Patent number: 6702830
    Abstract: Material transport catheters and methods for their use rely on rotation of an impeller within a catheter body. The impeller preferably comprises an inner tube or shaft having a helical rotor formed over an outer surface thereof. Optionally, in the case of a tubular shaft, a second helical rotor may be provided within the shaft lumen in order to induce flow in opposite or in the same direction as induced by the outer helical rotor. Catheters may further comprise structures near their distal ends for disrupting clot, and are preferably introduceable over guidewires where the helical rotors are rotated directly over the guidewire. The catheters may include two or more impellers or impellers having two or more rotors in order to provide for circulation of materials at a target site within a patient body lumen.
