Abstract
Abstract A needle guide is formed with a tubular section and an opened trough section connected thereto in aligned-spaced relationship. A clip member is formed and arranged to releasably engage an open side of the trough section so that a portion of a lymph vessel may be cradled in the trough section and secured by the clip member. During cannulation the clip is held open and a needle is inserted through the tubular section which guides the needle into the cradled portion of the lymph vessel. The clip is then closed and the needle is held in position within the vessel by the pressure of the clip member.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
117 words
A integral device for guiding a cannula into a lymph vessel and for securing the cannula within the vessel, comprising: first restraining means on the device for supporting and securing a portion of said vessel along a straight line; second restraining means on the device for guiding the cannula along the same straight line for positioning the cannula tip within the lumen of the supported portion of the vessel; said second means including means for preventing said cannula from being advanced to a position where the cannula tip punctures the vessel a second time and extends out of said vessel; and tension means on the device for securing the cannula within the supported portion of the vessel.
Claim 2
Dependent Claim
117 words
A integral device for guiding a cannula into a lymph vessel and for securing the cannula within the vessel, comprising: first restraining means on the device for supporting and securing a portion of said vessel along a straight line; second restraining means on the device for guiding the cannula along the same straight line for positioning the cannula tip within the lumen of the supported portion of the vessel; said second means including means for preventing said cannula from being advanced to a position where the cannula tip punctures the vessel a second time and extends out of said vessel; and tension means on the device for securing the cannula within the supported portion of the vessel.
Claim 3
Dependent Claim
29 words
A device as described in claim 1, wherein the guide means comprises a tubular section having an opening formed along the line of sufficient size to receive the cannula.
Claim 4
Dependent Claim
24 words
A device as described in claim 1, wherein the means for supporting a portion of the vessel comprises a trough formed along the line.
Claim 5
Dependent Claim
31 words
A device as described in claim 1, wherein the means for securing the cannula comprises a clip means for engaging the vessel supporting means and an exposed portion of the vessel.
Claim 6
Dependent Claim
38 words
A device as described in claim 4, wherein the clip means includes: a base fixedly attached to the support means; and a movable member for releasably engaging an exposed portion of the vessel supported by the support means.
Claim 7
Independent Claim
115 words
A device for guiding a cannula into a vessel and for securing the cannula within the vessel, comprising: means for supporting a portion of the vessel along a straight line which comprises a trough formed along the line; means for guiding the cannula along the line so that the cannula tip may be advanced to a position within the lumen of the supported portion of the vessel which comprises a tubular member having an opening formed along thE line of sufficient size to receive the cannula, said tubular member and trough being spaced apart to facilitate placing the vessel within the trough; and means for securing the cannula within the supported portion of the vessel.
Claim 8
Independent Claim
115 words
A device for guiding a cannula into a vessel and for securing the cannula within the vessel, comprising: means for supporting a portion of the vessel along a straight line which comprises a trough formed along the line; means for guiding the cannula along the line so that the cannula tip may be advanced to a position within the lumen of the supported portion of the vessel which comprises a tubular member having an opening formed along thE line of sufficient size to receive the cannula, said tubular member and trough being spaced apart to facilitate placing the vessel within the trough; and means for securing the cannula within the supported portion of the vessel.
Claim 9
Dependent Claim
54 words
A device as described in claim 6, wherein the means for securing the cannula within the supported portion of the vessel comprises a clip means having a base fixedly attached to the trough and a movable arm positioned to engage an exposed portion of the vessel protruding from an open side of the trough.
Claim 10
Dependent Claim
67 words
A device as described in claim 6, wherein the supporting means and the guiding means are formed from an oversized needle having an opening therethrough of sufficient size to receive the cannula, said oversized needle having a portion of its circumference removed along a portion of its length adjacent a first end and a greater portion of its circumference removed along a central portion of its length.
Claim 11
Dependent Claim
50 words
A device as described in claim 8, wherein the oversized needle has a length substantially equal to the length of the cannula so that when the cannula is fully inserted into the oversized needle, the tip of the cannula lies within the lumen of the supported portion of the vessel.
Claim 12
Dependent Claim
27 words
An apparatus as described in claim 1, wherein said tension means comprises a biased clip means for securing the cannula within the supported portion of the vessel.
Claim 13
Independent Claim
86 words
A method for cannulating a lymph vessel comprising the steps of: isolating a portion of the lymph vessel to be cannulated by dissecting said vessel away from surrounding tissue; positioning a portion of the isolated vessel on a first clip portion shaped to support restrain and align the positioned portion of the vessel along an axis; inserting and guiding a cannula along a cannula restraining means on a second portion of said clip along said axis; and penetrating into said lymph vessel lumen with said cannula.
Claim 14
Independent Claim
86 words
A method for cannulating a lymph vessel comprising the steps of: isolating a portion of the lymph vessel to be cannulated by dissecting said vessel away from surrounding tissue; positioning a portion of the isolated vessel on a first clip portion shaped to support restrain and align the positioned portion of the vessel along an axis; inserting and guiding a cannula along a cannula restraining means on a second portion of said clip along said axis; and penetrating into said lymph vessel lumen with said cannula.
Claim 15
Dependent Claim
41 words
A method as described in claim 11, additionally comprising the step of engaging by pressure the supported portion of the vessel and the penetrated portion of the cannula so as to secure the cannula within the supported portion of the vessel.
