A graft collector designed to facilitate and offer greater precision in performing the cutting and “dissection” of an area of the donor tissue in grafting operations. The graft collector is set as an anatomical grip handle based on a support head and fixation of a removable curved or angled blade. The cutting blade is provided with a cutting edge on two opposite sides, being folded in two points at 90°. The constructive arrangement of the graft collector allows the fixation of the cutting blade and its loosening and release for replacement. The said graft collector is a precise and anatomical grip instrument, designed for the good manual performance of the professional when cutting and removing the tissue to be used as a graft.

The present invention provides a system and method for collection, storage and processing of tissues and cells. The system includes a collection container with chambers for storing and processing tissues, which are controllably separated and maintain a physiologic environment for the tissues. The system also includes a fluidic device for isolating target cells of interest. The method includes receiving the tissue into a collection chamber, transferring the tissue to a processing chamber, dissociating the tis sue into single cells, and passing the single cells to a device for isolating one or more target cells.

A biopsy system includes various features. A tissue sample holder kit of the system comprises a rotatable member with chambers configured to receive tissue receiving features of a tissue sample tray. A biopsy device of the system includes user input features and user feedback features disposed on a body. A user interface of the system includes a graphical representation of a tissues ample holder. A biopsy site marker applier of the system includes markings associated with different biopsy device configurations. The biopsy system may undergo a multi-step initialization process. In operation, the biopsy system may execute pneumatic control algorithms including the use of vacuum, saline, and atmospheric air.

The present invention relates to an arrangement for taking a biopsy in a human or animal tissue, comprising an elongated hollow member having a circular cross-section in a plane perpendicular to a longitudinal axis, and a circular cutting edge at distal end. The circular cutting edge is provided with at least one cutting slit, running from the cutting edge in a proximal direction of the elongated hollow member. The arrangement further comprises a rotational member configured to apply rotational movement to the hollow member, wherein the rotational movement is applied in accordance to a rotational procedure such that the hollow member is rotated in one direction a predefined amount of rotations, and thereafter rotated in an opposite direction the same amount of rotations.

A biopsy needle device constructed in a manner such that an internal needle is triggered in response to unlocking operation of internal needle locking device, after which a piston is retracted by a piston retraction spring in response to unlocking operation of piston locking device, whereby negative pressure is generated in a recess of the internal needle resulting in suction of biological tissue into the recess, and an external needle is triggered in response to unlocking operation of external needle locking device, thereby cutting and sampling the biological tissue which has been drawn into the recess.

A full-core biopsy device comprises an outer cannula hub with an outer cannula coupled at a proximal end to the hub, the outer cannula with a tissue slicing feature defined at the distal tip configured for cutting tissue. The device further comprises an inner member hub and an inner member coaxially disposed within the outer cannula and coupled at a proximal end to the inner member hub. The inner member includes a tubular body, an inner member tip at an opposite distal end thereof and an elongated scoop portion defined between the tubular body and tip. The distal ends of the outer cannula and the scoop portion of the inner member define cooperating forcing cone features.

A biopsy assembly includes a biopsy device, a vacuum source, and a valve assembly. The biopsy device includes a body, a needle extending distally from the body, and a cutter translatable relative to the needle. The needle includes a lateral tissue receiving aperture. The cutter is translatable to selectively close the lateral tissue receiving aperture of the needle. The valve assembly is in fluid communication with the needle. The valve assembly includes a first valve, a second valve, and tubular member. Each of the first valve and the second valve selectively provide atmospheric venting or vacuum to the needle. The tubular member is coupled with the vacuum source and includes a first and second connector extending transversely from the tubular member. The first and second connectors couple to the first and second valves to provide vacuum to the first and second valves.

According to one aspect, a medical device including a shaft having a proximal and a distal end. The medical device may also include a handle coupled to the proximal end of the shaft. The medical device may further include a body at the distal end of the shaft. The body may have a wall defining a lumen within the body, and the lumen may have a longitudinal axis. The wall may include a protrusion at the distal end of the body, and the protrusion may be defined by a gap in the wall and may have a sharp portion configured to grasp tissue. The gap may extend proximally from the distal end of the body, and edges of the wall defining the gap may be transverse to the longitudinal axis.

Disclosed herein is a measuring probe and an arrangement for measuring spectral absorption, preferably in the infrared. Furthermore, the invention relates to a method for spectroscopically measuring absorption. The measuring probe may comprise a cutting apparatus configured to cut a slice or respectively flap off of a sample to be measured; a measuring gap configured to accommodate the sample slice; an optical window element for coupling measuring light into, or respectively out of the measuring gap; and an end reflector designed and arranged to reflect the measuring light propagated through the measuring gap back into the measuring gap. The arrangement for measuring spectral absorption may comprise the measuring probe, a light source and an apparatus for the spectral analysis of the measuring light coupled out of the measuring gap.

A biopsy punch device and method for making punch cuts at consistent predetermined depths. In an exemplary embodiment of the biopsy punch device includes two interconnecting pieces: an inner housing piece and an outer blocking cover piece. The inner housing piece releasably mounts cutting blades arranged in a desired geometric shape for biopsy punch cuts. The blocking cover piece overlays the inner housing piece in an assembled configuration and includes two openings: a larger distal end opening and a narrower proximal end cutting blade opening. The blocking cover distal end opening fits around and adjacent to the housing piece distal end. The blocking cover proximal end opening fits around and adjacent to the cutting blades. With the biopsy punch device in assembled position, the proximal side of the blocking cover piece provides a mechanical stop in the cutting process at the desired depth of penetration of the cutting blades.
