System, method and apparatus for integrated tissue sampling and tissue marker placement

An integrated, dual function medical apparatus configured to enable the collection of a tissue sample from a biopsy site of a patient and placement of a tissue marker at the biopsy site via a single insertion of the medical apparatus, the medical apparatus comprising:

• a tissue collection system including
• an outer cannula defining a sharp distal tip, a proximal actuator and an outer cannula wall defining a primary lumen extending therebetween, the outer cannula wall further defining a tissue receiving port in fluid communication with the primary lumen;
• and
• an inner cannula axially shiftable relative to the outer cannula between a first position enabling the tissue sample from the biopsy site of the patient to enter the primary lumen of the outer cannula through the tissue receiving port, and a second position enabling isolation of the tissue sample from the biopsy site for collection purposes;
• and
• a marker deployment device including structure defining a secondary lumen configured to house at least one tissue marker for selective deployment at the biopsy site, the secondary lumen separated from the primary lumen by an inner panel configured to separate the secondary lumen from the primary lumen, thereby enabling operation of the tissue collection system independent from the marker deployment device.

An integrated, dual function medical apparatus configured to enable the collection of a tissue sample and placement of a tissue marker at a biopsy site via a single insertion of the medical apparatus, the medical apparatus comprising:

• a tissue collection system including
• a stationary inner cannula defining a sharp distal tip, a proximal actuator and structure defining a tissue receiving port;
• and
• an outer cannula axially shiftable relative to the stationary inner cannula between a first position enabling the tissue sample from the biopsy site of the patient to enter the tissue receiving port of the stationary inner cannula, and a second position enabling isolation of the tissue sample from the biopsy site for collection purposes;
• and
• a marker deployment device including structure defining a secondary lumen configured to house at least one tissue marker for selective deployment at the biopsy site, the secondary lumen separated from the primary lumen by an inner panel configured to independently seal and separate the secondary lumen from the primary lumen, thereby enabling operation of the tissue collection system independent from the marker deployment device.

A method of collecting a tissue sample from a biopsy site of a patient and placement of a tissue marker at the biopsy site, the method comprising:

• inserting a sharp distal tip of an outer cannula into a patient to position a tissue receiving port defined by the outer cannula in proximity to a biopsy site of a patient;
• axially shifting an inner cannula relative to the outer cannula between a first position enabling the tissue sample from the biopsy site of the patient to enter a primary lumen of the outer cannula through the tissue receiving port, and a second position enabling isolation of the tissue sample from the biopsy site for collection purposes;
• and
• deploying at least one tissue marker at the biopsy site from a secondary lumen, wherein the secondary lumen is separated from the primary lumen by an inner panel configured to independently seal and separate the secondary lumen from the primary lumen.
