Methods, apparatuses and systems are described for implanting a plurality of fiducial markers into a tissue. Systems include a needle, a stylet sized to slide within a lumen of the needle, and a multi-stop stylet spacer having stopping features configured to engage with the stylet to stop the distal end of the stylet at one or more predetermined distances from the distal end of the needle. Methods for implanting a plurality of fiducial markers into a tissue are described and include inserting a needle preloaded with fiducial markers into a tissue, adjusting a multi-stop stylet spacer from a safety position to a first deployment position, deploying a first fiducial marker into the tissue, adjusting the stylet spacer from the first deployment position to a second deployment position, and deploying a second fiducial marker into the tissue.

Endoscopic ultrasound fine needle fiducial system

The present disclosure generally relates to a biopsy needle configured to maximize tissue sampling yield and collect a unit of sampled tissue. The biopsy needle includes an elongate tubular body comprising a lumen extending therethrough from a proximal open end to a distal open end of the body. The distal end includes first and second tip portions extending therefrom and formed on opposing sides of the needle body. The first tip portion generally extends further from the distal end than the second tip portion, resembling a staggered configuration, resulting in an increased surface area of multiple cutting edges formed between the first and second tip portions on either side of the needle body. Additionally, each of the tip portion defines a penetrating point configured to pierce the tissue to be sampled and direct sampled tissue towards the lumen of the body to be excised by the cutting edges.

Exchangeable core biopsy needle

The present disclosure provides an adjustable delivery handle system for interchangeably delivering a needle to a biopsy site. The adjustable delivery handle system includes a delivery handle having an inner hub housing component configured to interchangeably receive a needle subassembly that can be inserted into and withdrawn from the proximal handle member. The needle subassembly includes a biopsy needle having a distinct tissue collection distal end configured to maximize tissue sampling yield and collect a cohesive unit of sampled tissue. The distal end of the needle includes first and second tip portions extending therefrom and radially opposing one another. The first tip portion has a length greater than the second tip portion, thereby resulting in an increased surface area of a curvilinear cutting edge extending from the first tip portion to the second tip portion.

The present disclosure provides biopsy needles configured to maximize tissue sampling yield and further ensure collection of a cohesive unit of sampled tissue. The biopsy needles of the present disclosure provide a distinct tissue collection distal end configured to collect a full core of tissue sample and keep the full core intact. The distal end may include a distinct helical slot extending from an open distal end or a distinct cutting tip forming a coring feature.
