Tissue extraction and maceration device
Devices and methods are provided for extracting and macerating tissue, and optionally for depositing the tissue onto a tissue scaffold. The device generally includes an outer tube having a substantially open distal end that is adapted to be placed on and preferably to form a seal with a tissue surface, and a shaft rotatably disposed within the outer tube and movable between a first, proximal position in which the shaft is fully disposed within the outer tube, and a second, distal position in which a portion of a distal end of the shaft extends through the opening in the distal end of the outer tube. The device also includes a tissue harvesting tip formed on the distal end of the shaft that is effective to excise a tissue sample when the shaft is moved to the distal position, and a cutting member that is coupled to the shaft at a position proximal to the tissue harvesting tip. The cutting member is effective to macerate a tissue sample excised by the tissue harvesting tip.

ActiveUS20150216545A1Easy to harvestGentle on environmentSurgical needlesVaccination/ovulation diagnosticsCatheterWound site
Exemplary methods and devices can be provided for harvesting a plurality of small tissue pieces, e.g., having widths less than about 1 mm or 0.5 mm, using one or more hollow needles. A fluid can be flowed through a conduit past the proximal ends of the needles to facilitate removal of the tissue pieces from the needle lumens, and can maintain the tissue pieces in a controlled and protective liquid environment. A filter can be used to extract and collect the tissue pieces from the liquid, or the tissue pieces can be deposited directly onto a porous dressing. Such tissue pieces can be used as microscopic grafts, which can be applied directly to a wound site or provided on a substrate or dressing, or stored for later use. Such microscopic grafts can promote tissue regrowth and wound healing, or can be applied to a scaffold to grow new tissue.

Ergonomic needle tissue harvesting instrument not requiring a stylet
A medical diagnostic instrument for the ergonomic effective and safe harvesting of specimen at targeted remote tissue sites includes a pistol grip style handle with a hand activated lever and a specialized elongated flexible double tube needle shaft inside of a protective sheath for use, in a preferred embodiment, within an endoscope. The length of needle shaft is adjusted using locking buttons. Moving another set of buttons sets the needle penetration depth. With a squeeze of the lever, a novel thin band drive mechanism advances the needle shaft out of its sheath, through adjacent tissue and into the targeted site. The double tube needle shaft incorporates a pointed distal tip attached to an innermost “grater” needle, which has sharp edged tissue cutting holes or “grating” features that are exposed by retracting back an overlying cover tube. Sliding back the cover tube is achieved via a cam. The sharp cutting surfaces of the grater tube communicate directly with a vacuum source attached near the handle. Oscillation of the vacuum augmented grater tube back and forth within the targeted tissue yields small pieces of tissue for harvest. When adequate amounts of tissue are drawn into the grater tube, the cover tube is re-advanced over the distal grater tube, the needle shaft is retracted back into the sheath and the instrument along with the harvested specimen are removed from the patient.

Fluid jet cell harvester and cellular delivery system
ActiveUS20140058361A1Improve matchEasy to operateIntravenous devicesFluid jet surgical cuttersHigh pressureTarget tissue
An ultrasonically pulsating high-pressure fluid jet coupled with a suction system serve as a tissue harvesting device. The pulsated fluid jet disrupts tissue, permitting both harvesting of cells for therapeutic delivery, and as a surgical dissector and aspirator, for liposuction, soft tissue dissection, etc. The jet is delivered to the target tissue through a cannula, coupled to an aspiration system. An ultrasonically actuated rod vibrates within the cannula engaging a nozzle, disrupting the fluid jet into droplets, permitting tuning of the jet to the resonant frequencies and impact pressures necessary to dissociate the target tissue. A suction recovery system may be separated or integrally formed with the fluid jet cannula, and is linked by a closed tubing system appropriate for sterilization and subsequent delivery of the harvested cells / tissues with or without growth factor or matrix addition for human re-implantation or for in vitro expansion for later re-implantation.

A tissue harvesting method and device for obtaining micrograft tissue particles within the size range of 50-1500 microns, and more preferably 500-1000 microns, and most preferably 600 microns. The particles may be processed after a piece of donor tissue has been excised from the donor site, or processed into the desired size directly at the donor site, and thereafter excised. Cutters having blades or cutting edges spaced in the range of 50-1500 microns are utilized to obtain particles within the desired size range. An elastomer is positioned between the cutting edges to push the excised particles out of the blades for ease of use.
