Abstract
Abstract A guide ( 100 ) is provided for biopsy and microtherapy which includes an introducer cannula ( 120 ) defining a lumen ( 125 ) sized to receive a diagnostic or therapeutic item therethrough and a lateral opening ( 124 ) in communication with the lumen ( 125 ) adjacent the first end ( 121 ) of the cannula ( 120 ). The invention also includes a solid tip ( 130 ) having an anatomically distal end ( 131 ) secured to the first end ( 121 ) of the cannula ( 120 ) and a proximal end ( 132 ) configured to pierce tissue. A ramp ( 135 ) is disposed within the cannula ( 120 ) at an end ( 136 ) of the lateral opening ( 124 ) adjacent the first end ( 121 ) of the cannula ( 120 ). The ramp ( 135 ) is inclined toward the lateral opening ( 124 ), whereby the item will be deflected through the lateral opening ( 124 ) as it advances within the lumen ( 125 ) and exits the cannula ( 120 ). In some embodiments, the item is a biopsy needle, ablation means or a radiopharmaceutical seed. The invention also includes methods of obtaining a biopsy sample and methods for treating lesions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
119 words
A system for diagnosing and treating a lesion inside a patient, comprising: an introducer having a cannula having a first end and a second end and defining a lumen therebetween opening at a first aperture at said second end, said cannula defining a lateral opening in communication with the lumen adjacent said first end, and a solid tip having an anatomical distal end secured to the first end of said cannula and a proximal end, said distal end sloped to form a ramp adjacent and inclined toward said lateral opening, wherein said proximal end of said solid tip is configured to pierce tissue; and an item disposed within said lumen for transport through said lateral opening to the lesion.
Claim 2
Independent Claim
119 words
A system for diagnosing and treating a lesion inside a patient, comprising: an introducer having a cannula having a first end and a second end and defining a lumen therebetween opening at a first aperture at said second end, said cannula defining a lateral opening in communication with the lumen adjacent said first end, and a solid tip having an anatomical distal end secured to the first end of said cannula and a proximal end, said distal end sloped to form a ramp adjacent and inclined toward said lateral opening, wherein said proximal end of said solid tip is configured to pierce tissue; and an item disposed within said lumen for transport through said lateral opening to the lesion.
Claim 3
Dependent Claim
12 words
The system of claim 1 wherein said item is a diagnostic item.
Claim 4
Dependent Claim
12 words
The system of claim 1 wherein said item is a therapeutic item.
Claim 5
Dependent Claim
19 words
The system of claim 1 further comprising a plurality of depth markings located in spaced relation on said cannula.
