Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
119 words
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 positioned 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.
Claim 2
Independent Claim
119 words
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 positioned 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.
Claim 3
Dependent Claim
19 words
The system of claim 1 , wherein the advancing mechanism comprises a push rod that engages the medical device.
Claim 4
Dependent Claim
19 words
The system of claim 2 , wherein the proximal end of the push rod is secured to a handle.
Claim 5
Dependent Claim
15 words
The system of claim 3 , wherein the handle and cartridge can be selectively engaged.
Claim 6
Dependent Claim
22 words
The system of claim 4 , wherein the handle and cartridge are selectively engaged with a set of threads and a nut.
Claim 7
Dependent Claim

Claim 10
Independent Claim
115 words
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.
Claim 11
Independent Claim
115 words
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.
