Abstract
A system for selectively deploying a medical device includes a cartridge that is engageable with a proximal end of a delivery catheter that is routed to a desired location in a patient's body. An advancement mechanism is provided for advancing the medical device out of the cartridge and into the delivery catheter for deploying the medical device at the desired location in the patient's body.
Claims21
A system for selectively advancing a medical device into a patient;
- comprising:
- a delivery catheter having a distal end that is inserted into a patient's body, a proximal end that remains outside the patient's body and one or more lumens that extend between the proximal and distal end;
- a cartridge that is engageable with the proximal end of the delivery catheter, the cartridge including a lumen that aligns with a lumen in the delivery catheter when the cartridge is engaged with the proximal end of the delivery catheter;
- a medical device within the lumen of the cartridge;
- and
- an advancing mechanism for advancing the medical device out of the cartridge and into a lumen of the delivery catheter.
A system for delivering a medical device to a desired location in a patient, comprising:
- a cartridge having a proximal end, a distal end and a cavity therein;
- a connector on the distal end of the cartridge for engaging a proximal end of a delivery catheter such that the cavity is aligned with a lumen in the delivery catheter;
- a compressed medical device within the cavity of the cartridge;
- and
- means for advancing the medical device from the cartridge and into the lumen of the delivery catheter.
A system for delivery a medical device to a desired location in a patient, comprising:
- a cartridge having a proximal end, a distal end and a cavity therein;
- a connector on the cartridge that engages a corresponding connector on a proximal end of a delivery catheter in order to align the cavity with a lumen of the delivery catheter;
- a medical device collapsed within the cavity;
- a push rod that engages a medical device and advances it into the lumen of the delivery catheter;
- a handle secured to the push rod;
- and
- means for selectively moving the handle and the cartridge including means for limiting the movement of the cartridge with respect to the handle.
A method of deploying a medical device in a patient's body, comprising the acts of:
- advancing a distal end of a delivery catheter to a desired location in a patient's body;
- engaging a cartridge having a pre-loaded medical device therein to a proximal end of the delivery catheter;
- advancing the medical device out of the cartridge through a lumen of the delivery catheter to a distal end of the delivery catheter.
