US Patent:

20180070930, Mar 15, 2018

Filed:

Nov 17, 2017

Appl. No.:

15/816552

Inventors:

- MANSFIELD MA, US
EUGENE CAMPBELL - NATICK MA, US
BORA GUMUSTOP - SLINGERLANDS NY, US

International Classification:

A61B 10/02
A61B 8/08

Abstract:

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.

International Classification:

A61B 10/02
A61B 8/08

Abstract:

The present disclosure generally relates to a biopsy needle configured to maximize tissue sampling yield and collect a cohesive 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 first and second tip portions defines a penetrating point configured to pierce the tissue to be sampled and further direct sampled tissue towards the lumen of the body to be excised by the cutting edges upon contact therewith.

International Classification:

A61B 10/02
A61B 8/08

Abstract:

The present disclosure provides a biopsy needle configured to maximize tissue sampling yield and further ensure collection of a cohesive unit of sampled tissue. The biopsy needle of the present disclosure provides a distinct cutting slot defined on one side of a distal portion of the needle. The side cutting slot is configured to collect a full core of tissue sample and keep the full core intact.

Abstract:

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.

International Classification:

A61B 10/02

Abstract:

The present disclosure provides a device for needle biopsy having a novel delivery handle system for interchangeably delivering a needle to a biopsy site. The delivery handle system is adjustable in length and includes a proximal handle member slideably disposed over a middle handle member, and the middle handle member is slideably disposed over a distal handle member. The proximal handle member includes 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 needle having a distinct tissue collection distal end configured to collect a full core of tissue sample and keep the full core intact. The needle subassembly further includes a needle protector subassembly including a needle protection hub configured to receive the distal end of a needle.

International Classification:

Abstract:

The present disclosure generally relates to a biopsy needle configured to maximize tissue sampling yield and collect a cohesive 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 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. Additionally, each of the first and second tip portions defines a point configured to pierce the tissue to be sampled and further direct tissue towards the lumen of the body to be excised by the cutting edge upon contact therewith.
