Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
224 words
A medical instrument for use in a Lipectomy procedure comprising: a handle having a longitudinal body portion and having a continuously closed first end portion and a second end portion located at substantially opposite ends of said longitudinal body portion, wherein said longitudinal body portion has dimensions so that said handle may be grasped securely by a user. a first projection extending from said closed first end portion of said handle, having means for being interchangeably connected to a source of vacuum or a medical probe; said first projection extending from said closed first end portion of said handle at a first predetermined angle and having a passageway extending therethrough; a second projection extending from said closed first end portion of said handle, having means for being interchangeably connected to a source of vacuum or a medical probe; said second projection extending from said closed first end portion of said handle at a second predetermined angle differing from said first predetermined angle of said first projection and having a passageway extending therethrough, wherein said passageway of said second projection adjoins said passageway of said first projection substantially adjacent to said continuously closed first end portion of said handle to permit substantially direct fluid communication therebetween; and valve means provided within said first projection for selectively opening and closing said passageway of said first projection.
Claim 2
Dependent Claim
224 words
A medical instrument for use in a Lipectomy procedure comprising: a handle having a longitudinal body portion and having a continuously closed first end portion and a second end portion located at substantially opposite ends of said longitudinal body portion, wherein said longitudinal body portion has dimensions so that said handle may be grasped securely by a user. a first projection extending from said closed first end portion of said handle, having means for being interchangeably connected to a source of vacuum or a medical probe; said first projection extending from said closed first end portion of said handle at a first predetermined angle and having a passageway extending therethrough; a second projection extending from said closed first end portion of said handle, having means for being interchangeably connected to a source of vacuum or a medical probe; said second projection extending from said closed first end portion of said handle at a second predetermined angle differing from said first predetermined angle of said first projection and having a passageway extending therethrough, wherein said passageway of said second projection adjoins said passageway of said first projection substantially adjacent to said continuously closed first end portion of said handle to permit substantially direct fluid communication therebetween; and valve means provided within said first projection for selectively opening and closing said passageway of said first projection.
Claim 3
Dependent Claim
24 words
A medical instrument as in claim 1 and further comprising: means for interconnecting either said first or second projection to a source of vacuum.
Claim 4
Dependent Claim
15 words
A medical instrument as in claim 2 wherein said interconnecting means comprises: a transparent tube.
Claim 5
Dependent Claim
52 words
A medical instrument as in claim 3 and further comprising: an adapter; means at one end of said adapter for connecting said adapter to said first or second projection; and a projection at the other end of said adapter over which said transparent flexible tube means may be secured in sealing engagement.

Dependent Claim
26 words
A medical instrument as in claim 4 wherein: said connecting means of said adapter comprises a tapered outer surface on said one end of said adapter.
Claim 7
Dependent Claim
53 words
A medical instrument as in claim 5 wherein: said projection of said adapter is provided with a conical outer surface having portions with diameters greater than the inner diameter of said transparent flexible tube means so that an effective seal is formed when said transparent flexible tube is pushed over said outer surface.
Claim 8
Dependent Claim
59 words
A medical instrument as in claim 2 and further comprising: a medical probe having a predetermined shape and size; said medical probe having a passageway extending therethrough and having an opening at a first and second end thereof; and means at said first end of said medical probe for attaching said medical probe to said first or second projection.
Claim 9
Dependent Claim
41 words
A medical instrument as in claim 7 wherein a major portion of the length of said medical probe comprises a hollow tube; and said opening at said second end of said medical probe is in a side wall of said tube.

A medical instrument as in claim 8 wherein said attaching means at said first end of said medical probe comprises: a conical shaped surface surrounding said opening at said first end of said medical probe; and said passageways of said first and second projections having inner surfaces for providing a sealed joint with said conical shaped surface.
Claim 11
Dependent Claim
45 words
A medical instrument as in claim 1 wherein: the longitudinal axes of said handle and said first projection are in alignment; and the longitudinal axis of said second projection extends at a predetermined angle to said longitudinal axes of said handle and said first projection.
Claim 12
Dependent Claim
140 words
A medical instrument as in claim 1 wherein said valve means comprises: means in said first projection having a surface in sealing engagement with the inner surface of said first projection; a passageway in said means in sealing engagement with said inner surface having a longitudinal axis coinciding with at least a portion of said longitudinal axis of said first projection; means forming a cylindrical surface extending through said means in sealing engagement with said inner surface and intersecting said passageway; a stem having an outer surface for engagement with said cylindrical surface; a passageway extending through said stem and having a longitudinal axis extending at an angle of 90° to the longitudinal axis of said stem; and means for rotating said stem to move said stem passageway into and out of fluid communication with said passageway in said means.
Claim 13
Dependent Claim
43 words
A medical instrument as in claim 11 and further comprising: means for urging said stem into engagement with said cylindrical surface to provide frictional forces sufficient to hold said valve means in an opened or closed position but permitting rotation of said stem.
Claim 14
