Softening conduit for carrying fluids into and out of the human body
First Claim
1. A medical device for introducing fluid treating material to or removing a fluid material from a body cavity of a human or animal, comprising:
- a hollow, needle-like structure having a proximal end and a distal end, said proximal end having a tip beveled to a shape point and said needle-like structure being formed from a polymer which is sufficiently rigid at ambient temperature to permit puncture of skin by said point, and which becomes soft after a predetermined period of time exposed to body temperature and body fluids, thus preventing bodily trauma; and
a hub attached to the distal end of said hollow needle-like structure and having a diameter greater than that of said hollow needle-like structure, said hub including connector means for attachment of a handle or a device for introducing fluid treating material to or removing fluid from the body cavity.

Abstract
A medical device for introducing fluid treating material to or removing a fluid material from a body cavity of a human or animal, including:
a hollow, needle-like structure having a proximal end and a distal end, the proximal end having a beveled tip and being formed from a polymer which is sufficiently rigid at ambient temperature to permit puncture of skin by the beveled tip, and which becomes soft after a predetermined period of time exposed to body temperature and body fluids, thus preventing bodily trauma; and
a hub attached to the distal end of the hollow needle-like structure and having a diameter greater than that of the hollow needle-like structure, the hub including a connector for attachment of a handle or a device for introducing fluid treating material to or removing fluid from the body cavity.

17. A medical device for introducing fluid treating material to or removing a fluid material from a body cavity of a human or animal, comprising:
-
a hollow, needle-like structure having a proximal end and a distal end, said proximal end having a coring or non-coring tip beveled to a shape point and said structure being formed form a polymer which is sufficiently rigid at ambient temperature to permit puncture of skin by said point, and which becomes soft after a predetermined period of time exposed to body temperature and body fluids, thus preventing bodily trauma; a hub attached to the distal end of said hollow needle-like structure and having a diameter greater than that of said hollow needle-like structure, said hub having a proximal end attached to the distal end of said hollow needle-like structure, and a distal end including connector means for attachment of a handle or a device for introducing fluid treating material to or removing fluid from the body cavity; and a valve interposed in said hub between said proximal end and said distal end, said valve including means permitting flow of fluid only when a device for introducing or a device for removing is attached to said means for attaching. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
