INTRAOSSEOUS NEEDLE SETS

An intraosseous needle set is provided for penetrating a target area. The intraosseous needle set includes a cannula having a first end, a second end, and a bore. The bore may accommodate an intraosseous device, such that the intraosseous device and the cannula are operable to penetrate the target area. The bore has a length extending from the second end of the cannula through the first end of the cannula. The bore has a first cross-section with a substantially constant diameter along a majority of the length and extends from the second end of the cannula toward the first end of the cannula. The bore has a second cross-section along a minority of the length and extends from the first end of the cannula toward the second end of the cannula. The second cross-section may have a different shape than the first cross-section.

Apparatus and methods for aspirating tissue

A bone marrow aspiration device and associated method includes an introducer needle and an aspiration needle. The introducer needle includes an introducer cannula and a removable introducer stylet that includes a sharp tip to penetrate bone. The aspiration needle includes an optionally flexible aspiration cannula and a blunt stylet. The aspiration needle is receivable in the introducer cannula when the introducer stylet is removed from the introducer needle. The aspiration cannula forms a channel for aspirating bone marrow when the stylet is removed. The aspiration device also includes a locking mechanism to lock the aspiration cannula to the introducer cannula when the aspiration cannula is received in the introducer cannula, whereby the aspiration cannula can be advanced distally relative to the introducer cannula in a controlled manner, and whereby pulling the aspiration cannula proximally causes the introducer cannula to move proximally with the aspiration cannula.

Bone marrow harvesting device and storage methods

Bone harvesting tools and methods of use thereof are disclosed. In an embodiment, the tool comprises a chamber having a first aperture, a second aperture, an internal cavity, and a suction source fluidly connected with the chamber. The suction source is effective to generate negative pressure within the internal cavity of the chamber. The tool also has a reamer having a reaming portion, the reamer being sized to extend through the first and second apertures of the chamber, wherein the reamer is movable relative to the chamber. Additionally, the tool includes a storage container fluidly connected to the internal cavity of the chamber and effective to receive bone and/or cellular material extracted from the patient, the bone and/or cellular material being extracted during reaming a bone of the patient with the reamer.

Puncturing instrument and puncturing device

The present invention provide a puncture instrument capable of administering (supplying) a drug solution. The puncture instrument includes a puncture tip section (2); a first tubular body (3) connected to the puncture tip section (2) at the distal end; and an outer tubular body (5) at least partially covering the first tubular body (3). The first tubular body (3) is formed to be rotatable around an axis along the longitudinal direction. The first tubular body (3) has an outer diameter smaller than an inner diameter of the outer tubular body (5). A drug solution supply path (5a) is provided on the outside of the first tubular body (3).

Bone material harvesting device

A bone harvesting device includes a main body having an internal cavity and a suction port adapted to be coupled to a suction source. The device further includes an outer tube (200) having an interior surface, an exterior surface, a proximal end and a distal end, the proximal end of the outer tube being coupleable to the main body, an inner tube having an interior surface, an exterior surface, a proximal end and a distal end, the inner tube being in fluid communication with the internal cavity and at least partially disposed within the outer tube such that a venting channel is defined between at least a portion of the inner tube and at least a portion of the outer tube.

A bone marrow aspiration device and associated method includes an introducer needle assembly and an aspiration needle assembly. The introducer needle assembly includes an introducer cannula having proximal and distal ends, each end including an opening, and a screw assembly coupled to the introducer handle. The screw assembly includes a threaded tube and a lead screw receivable in the threaded tube. An outer cover is disposed around and in sealing engagement with the threaded tube and the lead screw. The aspiration needle assembly is receivable in the introducer cannula and includes an aspiration cannula forming a channel for aspirating bone marrow and including a flexible portion that extends from a distal end along a length of the aspiration cannula. A length of the aspiration cannula that extends beyond the distal end of the introducer cannula is adjustable by advancing the lead screw into or reversing the lead screw out of the threaded tube.

DEVICE AND METHOD FOR INSERTING A CANNULA TO A PREDETERMINED DEPTH WITHIN A BONE, IRRESPECTIVE OF THE THICKNESS OF THE TISSUE ABOVE THE BONE
20190076132 · 2019-03-14 ·

An intraosseous device, comprising a cannula through which life-saving fluids are transfusible into or out of bone marrow of a target bone when the cannula is penetrated into the target bone; a stylet which is engageable with the cannula; and means for causing penetration of the stylet and cannula, when mutually engaged, to a predefined depth within the target bone with respect to an outer surface of the target bone, the depth being irrespective of a thickness of tissue above the target bone.

COMBINED TROCAR AND CANNULA BONE MARROW ASPIRATION DEVICE WITH INTEGRAL VALVE AND PORTS FOR ASPIRATION, AND METHODS FOR USING SAME

A device comprising a trocar having a first end and comprising a cannulation and at least one fenestration proximal the first end; and a housing comprising a first port configured for the attachment of a first syringe and a second port configured for the attachment of a collection vessel, a first valve configured to selectively permit fluid flow through the cannulation of the trocar to the first port, and a second valve configured to selectively permit fluid flow through the cannulation of the trocar to the second port.
