Medical devices and methods of making and using such devices

A method of inhibiting conception in a patient having a first fallopian tube and a second fallopian tube, said method comprising:

• introducing a delivery system transcervically into a first fallopian tube, said delivery system having a first insert which is removably coupled to said delivery system and which is designed to be deployed within a portion of said first fallopian tube;
• expelling said first insert from said delivery system, wherein said first insert becomes deployed and wherein said first insert is formed at least in part from a non-biodegradable material;
• introducing said delivery system into a second fallopian tube, said delivery system having a second insert which is removably coupled to said delivery system and which is designed to be deployed within a portion of said second fallopian tube;
• expelling said second insert from said delivery system, wherein said second insert becomes deployed and wherein said second insert is formed at least in part from a non-biodegradable material;
• wherein said delivery system comprises:
• an outer sheath;
• a delivery catheter coaxially disposed within said outer sheath;
• a lumen disposed within said delivery catheter, said first insert and said second insert being serially disposed within said lumen;
• and
• wherein a biodegradable separator separates said first insert from said second insert within said lumen, and wherein said biodegradable separator is expelled into the first or second fallopian tube.
