Christopher Charles Andrews has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10335155
    Abstract: Intravascular implant systems and methods of positioning and detaching implants are described. One such system carries an implant by retaining an engagement member in a position proximal to an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by an elongate member that is coupled to the implant. Once the implant is in a desired implant position, the elongate member is released from the engagement member, and the implant is allowed to move away from the delivery system.
    Type: Grant

  • Patent number: 8795313
    Abstract: A medical device detachment system receives an elongate delivery member, having a lumen, and an elongate core member. The system includes a housing, a user input mechanism for receiving a user input to effect detachment of a medical device, such as an embolic coil, from a distal end of the delivery member, and a grasping mechanism for grasping and moving a proximal end of the core member relative to a proximal end of the delivery member. The system also includes a first sensor detecting positioning of the proximal end of the core member within the housing, and a second sensor, detecting movement of the grasping mechanism. An indicator is connected to the first and second proximity sensors and provides feedback to a user.

  • Patent number: 7615057
    Abstract: A device and method for removing a guide catheter from about a cardiac lead is disclosed. The device includes a blade for slitting the catheter so that the catheter may be removed from the lead. The blade includes upper and lower angled cutting surfaces which define a notch. The device includes a portion for receiving the lead and guiding the catheter to the blade.
