Introducer for biopsy device

A biopsy system, comprising:

• (a) a biopsy device, wherein the biopsy device includes:
• (i) a body,
• (ii) a needle extending distally from the body along a longitudinal axis, wherein the needle comprises a distal end and a proximal end, wherein the needle defines a lumen extending between the distal end and the proximal end, and
• (iii) a lateral aperture spaced proximally relative to the closed distal end of the needle;
• and
• (b) an introducer, wherein the introducer includes:
• (i) a cannula defining a lumen, wherein the lumen is sized to receive the needle of the biopsy device, wherein the lumen is sized to maintain at least two gaps between the needle and the cannula when the needle is received within the lumen, and
• (ii) a first leaf set, wherein the first leaf set comprises a first pair of leaves extending distally from a first side of the distal end of the cannula, and
• (iii) a second leaf set, wherein the second leaf set comprises a second pair of leaves extending distally from a second side of the distal end of the cannula,
• wherein the second side of the distal end of the cannula is opposite of the first side of the distal end of the cannula.

A biopsy system, comprising:

• (a) a biopsy device, wherein the biopsy device includes:
• (i) a body,
• (ii) a needle, wherein the needle includes a distal end and a proximal end, wherein the needle extends distally from the body at the proximal end, wherein a tip extends from the needle at the distal end, wherein the needle defines a first lumen,
• (iii) an opening spaced proximally relative to the distal end of the needle, wherein the opening is sized and configured to receive tissue samples, wherein the first lumen is in fluid communication with the opening and the body;
• and
• (b) an introducer, wherein the introducer includes:
• (i) a cannula, wherein the cannula includes a distal end and a proximal end, wherein the cannula defines a second lumen, wherein the second lumen is sized to receive the needle of the biopsy device, wherein the second lumen is in fluid communication with the distal end of the cannula, and
• (ii) at least two pairs of leaves, wherein the at least two pair of leaves extend distally from the distal end of the cannula, wherein the at least two pair of leaves include:
• (A) a first pair extending from a first wall of the distal end of the cannula, and
• (B) a second pair extending from a second wall of the distal end of the cannula,
• wherein the first wall is positioned opposite of the second wall along the distal end of the cannula, wherein the first pair is configured to resiliently deflect inwardly toward the second pair, wherein the second pair is configured to resiliently deflect inwardly toward the first pair,
• wherein the first pair and the second pair are configured to avoid the opening of the needle when the needle is moved proximally relative to the cannula from a distal position to a proximal position, wherein the opening of the needle is configured to be positioned distally relative to the first pair and the second pair when the needle is in the distal position.
