Systems, methods and devices for subcutaneous target location
Embodiments of the invention provide devices, systems, and methods that precisely identify a minimum of one predetermined spot which is hidden under a skin. The system comprises a locator device and corresponding implanted target device. The port locator device preferably comprises one magnet with north and south magnetic pole, a body and a suspending component. The body may utilize specific geometry which improves accuracy. The implanted target device may include at least one magnet and at least one target or a plurality of targets and at least one magnet. Various configurations can be provided that precisely identify a single spot or a plurality of spots which are hidden under a skin.
1. An assembly, comprising:
a base including a first infusion port and a target magnet housing;
a target magnet disposed in the target magnet housing, the target magnet including a magnetic pole proximal a first side of the target magnet housing and a magnetically opposite pole proximal a second side of the target magnet housing;
a locator assembly including a locator base and a locator housing, the locator base including a first port aperture proximal a side of the locator base, the locator base having a planar surface that is substantially orthogonal to a side of the housing, wherein the first port aperture is defined through the planar surface; and
at least two locator magnets respectively disposed at least partially within the locator housing proximal respective sides of the locator housing, wherein at least one of the at least two locator magnets is spaced from and adjacent to the first port aperture.
2. The assembly of claim 1 , wherein the base is elongated.
3. The assembly of claim 2 , wherein the elongated base is ellipsoidal shaped, rectangular shaped, or oblong.
4. The assembly of claim 1 , wherein the target magnet housing is disposed proximal a center of the base.
5. The assembly of claim 1 , wherein the target magnet housing is elongated.
6. The assembly of claim 1 , wherein the base includes a second infusion port disposed at a side of the base opposite to a side of the base including the first infusion port.
7. The assembly of claim 1 , wherein the target magnet housing includes at least one attachment aperture.
8. The assembly of claim 7 , wherein the attachment aperture includes a channel extending longitudinally along the target magnet housing.
9. The assembly of claim 1 , further comprising a suspending guide extending from the locator housing away from the locator base.
10. The assembly of claim 9 , further comprising a suspending line coupled to the suspending guide.
11. The assembly of claim 1 , wherein the at least two locator magnets are disposed with respect to each other with reversed magnetic poles.
12. The assembly of claim 1 , wherein at least one of the at least two locator magnets extends from a side of the locator base and into a portion of the locator housing.
13. The assembly of claim 12 , wherein at least one of the at least two locator magnets extends through the side of the locator base.
14. The assembly of claim 12 , wherein an end of at least one of the locator magnets extends from the side of the locator base and away from the locator housing.
15. The assembly of claim 1 , further comprising a second port aperture proximal a side of the locator base opposite to the side of the locator base including the first port aperture.
