The invention relates to a device in the form of a perforating trocar and is intended in particular to be used for surgery and interventional radiology. The device comprises an outer sleeve (5) having a rigid tube (8), and a mandrel (6) having a rod (18). The rod (18) is suitable for sliding in the outer sleeve (5) and has, at its distal end, a perforating tip (21, 33). The rod (18) additionally has a longitudinal groove (20) arranged on the surface of the rod (18), and extending from the distal end to the proximal end of the rod (18), in order to allow the device to slide on a guide pin.

Powered drivers, and kits and methods including or using powered drivers, having a driveshaft extending from a distal end of the housing and configured to slide responsive to a force applied to a distal end of the driveshaft and activate a motor to rotate the driveshaft. Some of the present powered drivers include a housing having a distal end and a proximal end; a motor disposed in the housing; a driveshaft extending outward from the distal end of the housing (e.g., in a direction away from the proximal end); a gearbox coupled to the motor and to the driveshaft such that activation of the motor will cause rotation of the driveshaft; and a battery configured to power the motor; where the gearbox is slidably disposed in the housing and configured such that, upon application of a threshold force on the driveshaft in the direction of the proximal end of the housing, the driveshaft and gearbox will slide toward the proximal end of the housing and thereby close an electrical circuit between the motor and the battery.

Apparatuses, systems, and methods are provided for securing an intra-osseous device within a safety device to prevent stick injuries and to guide the removal of the intra-osseous device from the bone of a patient. A body of the safety device has a cavity that receives the intra-osseous device, and the cavity guides the removal of the intra-osseous device along a straight line to prevent injury during removal. The intra-osseous device is drawn past a lock feature that secures the intra-osseous device within the body such that a needle of the intra-osseous device is contained within a cavity of the body and cannot injure the patient, staff members, etc.

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.

Apparatus and methods are provided to penetrate a bone and associated bone marrow using a powered driver. The powered driver is operable to insert an intraosseous device into a bone and associated bone marrow. The powered driver may include a housing having a distal end and a proximal end; a drive shaft having a first end disposed within the housing; a motor disposed within the housing and rotatably engaged with the drive shaft; a power supply to supply power to the motor; and a trigger assembly to activate the motor to rotate the drive shaft. A light may be connected to the power supply and operable to illuminate an insertion site for the intraosseous device.

Bone marrow access apparatus includes a bone penetrating member and a cap. The bone penetrating member includes a tubular insertion portion, and a head portion provided at a proximal end of the tubular insertion portion. A cross-sectional shape of the head portion is wider than a cross-sectional shape of the tubular insertion portion. A recess is provided in the head portion, and an internal channel is provided through the head portion and the tubular insertion portion. The cap accommodates the head portion of the bone penetrating member therein. The cap includes a lower wall which covers at least a part of a distal side of the head portion, and a projection which projects into the recess of the head portion.

The present disclosure provides a medical procedure kit for ameliorating tissue damage in a patient, the kit comprising a container enclosing a receptacle, an extractor for extracting biological material including autologous cells from the patient, a strainer for straining autologous cells from the biological material and an implantable support having a surface onto which the autologous cells can adhere, the implantable support configured to be received by the receptacle. Also disclosed are related methods of manufacturing a medical material and using the medical procedure kit.

A penetrator assembly for penetrating a bone and associated bone marrow is provided. The penetrator assembly may include a first connector having a first end and a second end; an outer penetrator extending from the second end of the first connector; the outer penetrator comprising a longitudinal passageway and a first tip; a second connector having a first end and a second end; and an inner penetrator extending from the second end of the second connector, the inner penetrator comprising a second tip. The first connector may be configured to engage the second connector, and the inner penetrator may be disposed in the longitudinal passageway of the outer penetrator when the first connector is engaged with the second connector.

An apparatus for accessing bone marrow inside a bone is provided. The apparatus may include a penetrator assembly having a tissue penetrator and a hub. The tissue penetrator my have a hollow cannula disposed in fixed relation to the hub. The apparatus may also have a driver configured to insert a portion of the tissue penetrator into the bone and bone marrow, and a depth control mechanism configured to control the depth of penetration of the tissue penetrator into the bone and bone marrow. The depth control mechanism may have a sensor configured to detect a position of the bone and bone marrow. The depth control mechanism may also have a mechanical stop.

A bone marrow access device includes a cannula and a sharp stylet removably positioned in the cannula. The cannula defines a distal opening at a distal tip and a side aperture in a side of the cannula, proximally from the distal opening. The stylet has a sharp distal tip and extends beyond the distal opening. A plug is receivable in the cannula distal to the side aperture to seal the distal opening when the stylet is removed. A method of accessing bone includes inserting the cannula and sharp stylet positioned in the cannula into bone; removing the sharp stylet from the cannula; pushing a plug through the cannula and distal to the side aperture to seal the distal opening of the cannula; and accessing the bone through the side aperture. Accessing the bone can include aspirating bone marrow, injecting a substance, or inserting an instrument into the bone.
