Abstract

Devices, systems, and methods provide accurate and consistent identification of the center of a magnetic infusion port.

Claims

exact text as granted — not AI-modified
1 . A system for locating an implanted infusion port comprising:
 an infusion port, the infusion having a magnetic portion, the magnetic portion having a first surface having a first magnetic polarity and a second surface having a second magnetic polarity; and   a port finder, the port finder having a first surface and a second opposite facing surface, the first surface having a first magnetic polarity and the second surface having a second opposite magnetic polarity, the port finder having a center hole extending through the port finder from the first surface to the second surface.   
     
     
         2 . The system of  claim 1  further comprising a sleeve. 
     
     
         3 . The system of  claim 2  wherein the sleeve has an interior cavity sized and configured to receive the port finder. 
     
     
         4 . The system of  claim 2  wherein the sleeve has an opening adjacent the interior cavity, the opening being sized and configured to receive the port finder. 
     
     
         5 . The system of  claim 2  wherein the sleeve has a sticky back side. 
     
     
         6 . The system of  claim 5  wherein the back side has a cover that may be peeled back to expose the sticky material. 
     
     
         7 . The system of  claim 2  wherein the back side of the sleeve includes an anesthetic. 
     
     
         8 . The system of  claim 1  further comprising a flexible member coupled to the port finder. 
     
     
         9 . The system of  claim 8  wherein the flexible member is a string. 
     
     
         10 . The system of  claim 1  wherein said port finder center hole is sized and configured to allow passage of a needle therethrough. 
     
     
         11 . The system of  claim 1  wherein said port finder center hole is sized and configured to allow passage of a marking apparatus therethrough. 
     
     
         12 . A method comprising:
 providing a magnetic infusion port;   providing a magnetic port finder;   implanting the magnetic infusion port.   
     
     
         13 . The method of  claim 12  further comprising using the magnetic port finder to locate the magnetic infusion port. 
     
     
         14 . The method of  claim 13  further comprising inserting a needle through the center of the magnetic port finder into the magnetic infusion port. 
     
     
         15 . The method of  claim 13  further comprising marking the location of the magnetic infusion port on the through the center of the magnetic port finder. 
     
     
         16 . The method of  claim 15  further comprising
 removing the magnetic port finder; and 
 inserting a needle into the magnetic infusion port at the marked spot. 
 
     
     
         17 . The method of  claim 12  further comprising
 providing a sleeve; 
 inserting the magnet into the sleeve; and 
 using the magnetic port finder to locate the magnetic infusion port. 
 
     
     
         18 . The method of  claim 17  wherein at least one surface of the sleeve has an adhesive substance thereon. 
     
     
         19 . The method of  claim 18  further comprising inserting a needle through the center of the magnetic port finder into the magnetic infusion port. 
     
     
         20 . The method of  claim 19  further comprising
 removing the needle from the magnetic infusion port; and 
 removing the magnet from the sleeve, the sleeve remaining to serve as a bandage. 
 
     
     
         21 . The method of  claim 18  further comprising
 removing the magnet from the sleeve; and 
 inserting a needle through the sleeve into the magnetic infusion port. 
 
     
     
         22 . The method of  claim 21  further comprising
 removing the needle from the magnetic infusion port; and 
 allowing the sleeve to remain to serve as a bandage. 
 
     
     
         23 . The method of  claim 22  further comprising placing an anesthetic on the backside of the sleeve. 
     
     
         24 . A system for locating an implanted infusion port comprising:
 an infusion port, the infusion having a magnetic portion, the magnetic portion having a first surface having a first magnetic polarity and a second surface having a second magnetic polarity; and   a port finder, the port finder having a first pole having a first magnetic polarity and a second pole having a second opposite magnetic polarity, the port finder having a center hole extending through the port finder from the first pole to the second pole.   
     
     
         25 . The system of  claim 24  wherein the port finder has a generally spherical configuration.
