Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A flexible magnetic pad for therapeutic use by direct application upon a human body, wherein at least one blood vessel of the human body traverses under said magnetic pad, comprising: a flexible pad having an active surface with permanent magnetic particles embedded therein with said magnetic particles forming individual contiguous magnetic north and south polarity zones so that each of said polarity zones is positioned adjacent to at least three other of said polarity zones of opposite polarity, said adjacent magnetic north and south polarity zones being oriented so that at least one blood vessel will be in contact with alternate polarity zones irrespective of where said blood vessel is located while said blood vessel traverses any portion of said flexible pad.
Claim 2
Dependent Claim
122 words
A flexible magnetic pad for therapeutic use by direct application upon a human body, wherein at least one blood vessel of the human body traverses under said magnetic pad, comprising: a flexible pad having an active surface with permanent magnetic particles embedded therein with said magnetic particles forming individual contiguous magnetic north and south polarity zones so that each of said polarity zones is positioned adjacent to at least three other of said polarity zones of opposite polarity, said adjacent magnetic north and south polarity zones being oriented so that at least one blood vessel will be in contact with alternate polarity zones irrespective of where said blood vessel is located while said blood vessel traverses any portion of said flexible pad.
Claim 3
Dependent Claim
23 words
The flexible magnetic pad for therapeutic use according to claim 1, wherein said polarity zones are each between 4 mm-10 mm in width.
Claim 4
Dependent Claim
19 words
The flexible magnetic pad for therapeutic use according to claim 1, wherein said polarity zones alternated radially and circumferentially.
Claim 5
Dependent Claim
34 words
The flexible magnetic pad for therapeutic use according to claim 1, wherein the average distance between said polarity zones of alternating polarity remains substantially constant for a blood vessel traversing between alternate polarity zones.
Claim 6
Dependent Claim
41 words
The flexible magnetic pad for therapeutic use according to claim 1, wherein said polarity zones form a checkerboard pattern of alternating polarities so that each of said polarity zones is contiguous with another four of said polarity zones of opposite polarity.
Claim 7
Dependent Claim
22 words
The flexible magnetic pad for therapeutic use according to claim 1, wherein said polarity zones form a spiral pattern of alternating polarities.
