Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge), hollow needle is inserted into the mass for sampling of cells that, after being stained, will be examined under a microscope (biopsy). The sampling and biopsy considered together are called fine-needle aspiration biopsy (FNAB) or fine-needle aspiration cytology (FNAC) (the latter to emphasize that any aspiration biopsy involves cytopathology, not histopathology). Fine-needle aspiration biopsies are very safe minor surgical procedures. Often, a major surgical (excisional or open) biopsy can be avoided by performing a needle aspiration biopsy instead, eliminating the need for hospitalization. In 1981, the first fine-needle aspiration biopsy in the United States was done at Maimonides Medical Center. Today, this procedure is widely used in the diagnosis of cancer and inflammatory conditions.

Rotating fine needle for core tissue sampling
ActiveUS20060116605A1Easy to collectSmall diameterSurgical needlesVaccination/ovulation diagnosticsSurgical siteEcho endoscopie
A medical instrument usable with an ultrasound-endoscope for performing a needle biopsy on a patient's internal body tissues usable at a surgical site not visible to the unaided eye or viewed endoscopically, comprises an elongate tubular member with a hollow needle element connected at its distal end, a sheath member housing said tubular member and needle element, an actuator subassembly with a shifter member operatively connected to elongate tubular member's proximal end, and a distal camming subassembly, said subassembly enabling a rotating motion of said needle member while handle actuator is moved in the forward direction. Upon inserting an ultrasound-endoscope into a patient and locating a mass, the fine needle with sharply pointed spoon shaped distal end is inserted into the mass aided by endoscopic and ultrasonographic guidance. Once in the mass, a camming action is initiated, causing rotation of the fine needle within the mass, resulting in a scooped out core biopsy. This instrument enables the performance of a fine needle aspiration requiring only one or two needle introductions, with a resultant core biopsy substantial enough for diagnostic purposes.

Miniature ingestible capsule
ActiveUS20110065987A1Improve and enhance visualizationSlow motionSurgeryEndoscopesMotor controlBiopsy forceps
A miniature ingestible capsule has multiple therapeutic or diagnostic operations that can be performed. These functions are controlled by a combination of an outside control, a pose beacon and through information relayed from an imagining array and transmitter. These functions can be in a separate capsule without an imaging array or within the same capsule with an imaging array. Typically, there is one function performed in addition to imaging. These functions can include suction and spray capabilities, ultrasound sensor, lithotripsy, laser, heat, electrocautery, BICAP, biopsy forceps, a needle knife snare cautery (cold and hot with continuous or pulsed current for cutting and coagulation), with a basket, and fine needle aspiration with various wheels and fins and motors controlled externally and other tools to be used in humans. All of these tools can be attached to a retractable arm. Also, they can be used on an elevator device that lifts them, allowing for an extra 180° of movement.

An arrangement for taking a sample of cells from a suspicious lesion or a tumour with the so called fine needle aspiration technique, provides a good penetration of tumours, especially small and / or hard fibrous tumours, and in the meantime yielding an increased amount of cells in the sample, by applying a longitudinal movement to the needle when the needle is penetrating the tumour and by applying both a rotational and a longitudinal movement to the needle when the needle is positioned inside the tumour. The arrangement is further provided with heat generating elements in order to apply a short pulse of heat to the needle in order to lower the risk for the tumour to spread.

Flared Needle for EUS Fine Needle Aspiration Device
InactiveUS20110046512A1Increase the diameterSmall outer diameterSurgical needlesVaccination/ovulation diagnosticsDistal portionTissue sample
A device for gathering tissue samples includes a needle defining a distal tissue penetrating tip. The needle includes an increased diameter proximal portion extending proximally from the distal tip. An outer diameter of the distal tip is smaller than an outer diameter of the proximal portion. The needle defines a lumen extending therethrough from a distal opening in the distal tip thereof to a proximal opening at a proximal end thereof. The lumen includes a distal portion having a first inner diameter and a proximal portion having a second diameter greater than the first diameter. The device also includes a stylet slidably received within the lumen. An outer diameter of a distal portion of the stylet is substantially equal to the inner diameter of the distal portion of the lumen so that, when the stylet is in an extended position extending to the distal opening of the lumen, the lumen is substantially sealed thereby, and when, in a retracted position in which a distal end of the stylet is received within the proximal portion of the lumen, an annular space surrounding the stylet defines an aspiration path for samples exiting the distal portion of the lumen.
