Abstract
A mechanical locking assembly for an endovascular device, comprising a shaft comprising a main body a shaft comprising a main body and enlarged end, an inner channel component comprising a full collar formed on proximal end of the inner channel component, and an outer cage component comprising a partial collar formed on the outer cage component wherein the full collar of the inner channel component fully surrounds the outer cage component and the partial collar of the outer cage component at least partially surrounds the shaft.
Claims20
A proximal mechanical locking assembly for a thrombectomy device, comprising:
- a shaft comprising a main body and enlarged end;
- an inner channel component comprising a proximal collar;
- and
- an outer cage component comprising a proximal strut, the proximal strut comprising a slot opening therethrough,
- wherein the enlarged end is positioned within the slot opening of the outer cage component and the proximal collar of the inner channel component at least partially surrounds the enlarged end and the slot opening.
A joint assembly for an endovascular device, comprising:
- a shaft comprising a main body and an enlarged end, the enlarged end having a top end and a bottom end;
- a first proximal strut comprising a first strut slot, wherein the first strut slot engages the top end of the enlarged end of the shaft;
- a second proximal strut comprising a second strut slot, wherein the second strut slot engages the bottom end of the enlarged end of the shaft;
- and
- a locking collar at least partially covering the enlarged end of the shaft, the first strut slot of the first proximal strut, and the second strut slot of the second proximal strut.
A joint assembly for an endovascular device, comprising:
- a shaft comprising a main body and an enlarged end;
- a proximal strut comprising a strut slot and at least one strut slit;
- and
- a locking collar having a distal face and at least one collar pin protruding from the locking collar near the distal face of the locking collar,
- wherein the strut slot engages the enlarged end of the shaft, and
- wherein the proximal strut is configured to flex to permit the strut slit to lockingly engage the at least one collar pin.
