Abstract: A method of using a biopsy apparatus includes moving a stylet cannula relative to a vacuum cannula between a first extended position and a first retracted position; and receiving a protrusion member within a flared portion of the vacuum cannula when the stylet cannula is in the first retracted position.

Abstract: A biopsy device includes a cutting cannula and an inner member. The inner member has a rotatable toothed rack, a sharpened distal tip, and a sample notch. The inner member is configured to be received in the cutting cannula. The rotatable toothed rack has a proximal portion and a rotation zone in the proximal portion. The rotation zone of the rotatable toothed rack has circumferential toothing configured as a series of longitudinally spaced cut-outs that run around an entire circumference of the rotatable toothed rack to facilitate both a longitudinal movement and a rotational movement of the rotatable toothed rack and inner member. A drive is configured to engage the circumferential toothing to move the rotatable toothed rack within the cutting cannula in at least one of the longitudinal movement and the rotational movement.

Abstract: A biopsy apparatus includes a biopsy probe assembly that is releasably attached to a driver assembly. The biopsy probe assembly has a vacuum cannula and a stylet cannula coaxially arranged. The vacuum cannula has a flared portion that extends distally from an elongate portion. The stylet cannula is movable between a first extended position and a first retracted position. The stylet cannula has a distal portion having a sample notch and a protrusion member that extends proximally in a lumen of stylet cannula along a portion of a longitudinal extent of the sample notch, wherein when the stylet cannula is in the first retracted position, the protrusion member is received within the flared portion of the vacuum cannula. The biopsy apparatus may further include a controller circuit that has a virtual energy reservoir, and the controller circuit executes program instructions to control current to motors when engaging dense tissue.

Abstract: The present disclosure relates to administration of fluid medication, in particular medication and dosing regimen for management of pain, more specifically to an anesthetic and dosing regimen for anesthetic for perioperative pain management and/or for palliative care. The present disclosure relates further to a medication pump and a method for delivering medication using the medication pump.

Abstract: A biopsy device for obtaining tissue samples from human or animal tissue is optimized for the sampling of tissues that are resilient and difficult to cut using conventional approaches. The biopsy device includes a cutting cannula, an inner member including a toothed rack having a sharpened distal tip configured to be introduced into the body and a sample notch for receiving the at least one severed tissue sample, the inner member receivable in the cutting cannula, and a cutting mechanism configured for causing the cutting cannula to be longitudinally displaced in a distal direction from a first position at the proximal end of the sample notch exposing the sample notch, to a second position at the distal end of the sample notch, so as to sever said tissue sample from remaining body tissue at the harvesting site. The toothed rack may be a rotatable and may be rigid.

Abstract: An connector assembly for use in, for example, a hearing aid, the assembly having a first connector and a second connector adapted to be detachably attached and being able to transport both sound and electric signals. The invention also relates to an assembly comprising the connector assembly and having a first part comprising an electrical input and a sound providing receiver as well as both an audio output and an electrical output. The two outputs are connected to a second element, normally for positioning inside an ear canal of a person, the second element having a receiver for receiving the electrical signal from the first elements and providing a corresponding sound which is mixed with the sound output by the second element, the mixed sound being output from the second element. The receiver of the first element may be a woofer, and the receiver of the second element may be a tweeter.
