An introducer guidefor introducing medical items into an internal tissue of a patient is provided. The guideincludes a cannuladefining a lumen sized to receive the item and a lateral openingA ramp is disposed within the lumen adjacent and inclined toward the lateral openingA hub' is attached to the second endof the cannulaThe hub&#x2032; includes a gripping portion&#x2032; configured to be held when inserting and positioning the introducerThe gripping portion&#x2032; has a length lsufficient for gripping and a tactile indicatordisposed along substantially the entire length lof the gripping portionon the hub&#x2032;. The indicatorhas a fixed angular relationship with the lateral openingThe invention also includes methods for obtaining a biopsy sample and methods for treating lesions.

Surgical and pharmaceutical site access guide

A guide ( ) is provided for biopsy and microtherapy which includes an introducer cannula ( ) defining a lumen ( ) sized to receive a diagnostic or therapeutic item therethrough and a lateral opening ( ) in communication with the lumen ( ) adjacent the first end ( ) of the cannula ( ). The invention also includes a solid tip ( ) having an anatomically distal end ( ) secured to the first end ( ) of the cannula ( ) and a proximal end ( ) configured to pierce tissue. A ramp ( ) is disposed within the cannula ( ) at an end ( ) of the lateral opening ( ) adjacent the first end ( ) of the cannula ( ). The ramp ( ) is inclined toward the lateral opening ( ), whereby the item will be deflected through the lateral opening ( ) as it advances within the lumen ( ) and exits the cannula ( ). 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.

Surgical and pharmaceutical site access guide and methods

An introducer guide,for introducing medical items into an internal tissue of a patient is provided. The guide,includes a cannula,defining a lumen sized to receive the item and a lateral opening,. A ramp is disposed within the lumen adjacent and inclined toward the lateral opening,. A hub,&prime; is attached to the second end,of the cannula,. The hub,&prime; includes a gripping portion,&prime; configured to be held when inserting and positioning the introducer,. The gripping portion,&prime; has a length l,sufficient for gripping and a tactile indicator,disposed along substantially the entire length l,of the gripping portion,on the hub,&prime;. The indicator,has a fixed angular relationship with the lateral opening,. The invention also includes methods for obtaining a biopsy sample and methods for treating lesions.

A guide (,) is provided for biopsy and microtherapy which includes an introducer cannula (,) defining a lumen (,) sized to receive a diagnostic or therapeutic item therethrough and a lateral opening (,) in communication with the lumen (,) adjacent the first end (,) of the cannula (,). The invention also includes a solid tip (,) having an anatomically distal end (,) secured to the first end (,) of the cannula (,) and a proximal end (,) configured to pierce tissue. A ramp (,) is disposed within the cannula (,) at an end (,) of the lateral opening (,) adjacent the first end (,) of the cannula (,). The ramp (,) is inclined toward the lateral opening (,), whereby the item will be deflected through the lateral opening (,) as it advances within the lumen (,) and exits the cannula (,). 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.

A biopsy needle device (10) is provided which includes an introducer cannula (20) defining a lumen (25) sized to receive a biopsy needle (11) therethrough and a lateral opening (24) in communication with the lumen (25) adjacent the first end (21) of the cannula (20). The invention also includes a solid tip (30) having an anatomically distal end (31) secured to the first end (21) of the cannula (20) and a proximal end (32) configured to pierce tissue. A ramp (35) is disposed within the cannula (20) at an end (36) of the lateral opening (24) adjacent the first end (21) of the cannula (20). The ramp (35) is inclined toward the lateral opening (24), whereby a biopsy needle (11) will be deflected through the lateral opening (24) as it advances within the lumen (25) and exits the cannula (20). The invention also includes methods of obtaining a biopsy sample using the biopsy device 10 in which a sample is taken, the biopsy needle (11) is retracted, the cannula (20) is rotated and the needle 11 is readvanced to obtain another sample from a different site.
