All refrences to claim(s) which appear below refer to the numbering after this setence.
We claim:
1. A blood filter mechanism for use in a vascular lumen comprising:
an implantable filter having an active state and an inactive state;
said filter, when in said active state, being positioned to catch blood clots while said filter is implanted in the vascular lumen; and
said filter, when in said inactive state, being positioned to pass blood clots while said filter is implanted in the vascular lumen.
2. The blood filter mechanism as claimed in claim 1 further comprising a switching mechanism to switch said filter from said active state to said inactive state.
3. The blood filter mechanism as claimed in claim 2, wherein said switching mechanism comprises
a breakable element holding said filter in a position to intercept particles in blood flowing in the vascular lumen to establish said active state; and
said filter switched from said active state to said inactive status by breaking said breakable element.
4. The blood filter mechanism as claimed in claim 3, wherein said filter is biased toward said inactive state.
5. The blood filter mechanism as claimed in claim 3, wherein said breakable element remains attached to said filter after said breakable element is broken.
6. The blood filter mechanism as claimed in claim 3, wherein said breakable element is removed from said filter after said breakable element is broken.
7. The blood filter mechanism as claimed in claim 3, wherein said breakable element is composed of Teflon.
8. The blood filter mechanism as claimed in claim 1, wherein said filter comprises a first and second portion; said first portion being positioned to intercept particles in blood flowing in the vascular lumen in said active state; said second portion being held against the walls of the vascular lumen in both of said states; said first portion being disengaged from said second portion in said second state.
9. The blood filter mechanism as claimed in claim 8, wherein said first portion is disengaged from said second portion by detaching a hook connecting said first portion to said second portion.
10. The blood filter mechanism as claimed in claim 8, wherein said first portion is disengaged from said second portion by breaking a weakened portion connecting said first portion with said second portion.
11. The blood filter mechanism as claimed in claim 1, wherein said filter is attached to the vascular lumen by a barbed anchor.
12. The blood filter mechanism as claimed in claim 1, wherein said switching mechanism comprises a latch mechanism capable of holding a portion of said filter in a position that interferes with blood flowing in the vascular lumen to establish said active state; and
wherein said filter is switched from said active state to said inactive state by activating said latch mechanism.
13. The blood filter mechanism as claimed in claim 12, wherein said filter is biased toward said inactive state.
14. The blood filter mechanism as claimed in claim 1, wherein said filter comprises a plurality of filtering portions;
said plurality of filtering portions capable of being wrapped around each other to be held in a position to intercept particles in blood flowing in the vascular lumen when in said active state; and
said filter is switched from said active state to said inactive state by unwrapping said filtering portions from each other.
15. The blood filter mechanism as claimed in claim 14, wherein said filter is biased towards said inactive state.
16. The blood filter mechanism as claimed in claim 1, wherein said filter forms a conical shape in said active state.
