摘要： Assistive apparatuses or devices, kits, and methods for assisting with removal of a biological sample from an intraosseous device are described. Some of the present assistive apparatuses comprise: a body including a first end and a second end, and defining a channel with a first portion having a first transverse dimension, a second portion disposed between the first portion and the second end and having a second transverse dimension that is smaller than the first transvers dimension, and a longitudinal axis extending through the first portion and the second portion, the body further including a protrusion extending laterally outward relative to the longitudinal axis; where the channel is configured to receive a portion of an intraosseous device having a hub and a cannula extending from the hub, with the first portion of the channel receiving a part of the hub, and the second portion of the channel receiving a part of the cannula while preventing passage of the hub through the second portion.

摘要： Apparatus and methods are provided to remove biopsy specimens from a bone and/or associated bone marrow using a powered driver and an intraosseous (IO) needle set. The powered driver may rotate the IO needle set at an optimum speed to obtain a biopsy sample of bone and/or bone marrow. Apparatus and methods may also be provided for aspiration of bone marrow and/or stem cell transplant procedures. The apparatus may include a powered driver, a coupler assembly, a containment bag or sterile sleeve and various IO needles and IO needle sets with associated hubs and/or hub assemblies. Each IO needle set may include a cannula or catheter and an associated trocar stylet with respective tips operable to penetrate a bone and/or bone marrow with minimum trauma to a patient. Each hub assembly may be used to releasably dispose a respective stylet within an associated generally hollow cannula. Some coupler assemblies and/or hub assemblies may also be used with manual drivers.

摘要： Powered drivers operable to insert an intraosseous device into a bone are disclosed. Some of the present powered drivers include a housing having a distal end and a proximal end. A driveshaft may be located near the distal end of the housing and configured to engage a portion of the intraosseous device. A motor may be disposed in the housing and operable to rotate the driveshaft. A power source may be disposed within the housing and configured to power the motor. The powered drivers may include a lockout operable to prevent activation of the driver for increased safety when handling the driver.

摘要： An apparatus and method for penetrating bone marrow is provided. The apparatus may include a housing such as a handheld body, a penetrator assembly, a connector that releasably attaches the penetrator assembly to a drill shaft, a gear mechanism, a motor and a power supply and associated circuitry operable to power the motor. The penetrator assembly may include a removable inner trocar and an outer penetrator or needle. It may also include a grooved trocar that allows bone chips to be expelled as the apparatus is inserted into bone marrow. Various connectors are provided to attach the penetrator assembly to the drill shaft.

摘要： Powered drivers operable to insert an intraosseous device into a bone and associated bone marrow are disclosed. Some of the present powered drivers may include a housing having a distal end and a proximal end; a motor disposed in the housing; a driveshaft at the distal end of the housing; and a gearbox coupled to the motor and to the driveshaft. Activation of the motor causes rotation of the driveshaft. The housing may include a power source configured to power the motor. The driveshaft may be 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 will slide toward the proximal end of the housing to cause an electrical circuit between the motor and the power source to close.

摘要： Medical procedure trays and related methods are provided to accommodate joining a first non-sterile medical device with a second sterile medical device and maintaining required sterilization of the second sterile medical device to perform an associated medical procedure. One example of such medical procedures includes biopsy of a bone and/or associated bone marrow using a non-sterile powered driver and a sterile biopsy needle or biopsy needle set. Each medical procedure tray may include a containment bag or sterile sleeve. A coupler assembly, one or more sharps protectors, a biopsy sample ejector and/or associated ejector funnel may also be included. Some medical procedure trays may allow engaging a non-sterile powered driver with one end of a coupler assembly and sealing the non-sterile powered driver in a sterile sleeve or containment bag without compromising sterility of other components in the medical procedure tray.
