Intraosseous Device and Data Transfer
Disclosed herein are medical device systems, and methods thereof. Exemplary medical devices can include intraosseous (IO) access device systems, or similar medical devices that include a motive force. Embodiments include replaceable and rechargeable batteries that are configured to store one or more performance characteristics of the medical device and transfer the performance characteristic to a base station when the battery is removed from the medical device and coupled with the base station for recharging. The base station can then store performance characteristics from one or more batteries and/or medical devices. The performance characteristics can be transferred from the base station to one or more external computing devices or networks.
ASSEMBLY FOR COUPLING POWERED DRIVER WITH INTRAOSSEOUS DEVICE
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.
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.
Biopsy device having a linear motor
A biopsy device includes a device housing, a linear motor, and a controller circuit. The controller circuit has a processor circuit, a first feedback circuit, and a second feedback circuit. The first feedback circuit and the second feedback circuit operate simultaneously. The processor circuit executes program instructions to control an axial advancement of the distal end of the linear motor shaft in accordance with a linear motor shaft advancement profile based on first control signals received from at least one drive characteristic sensor of the first feedback circuit, and executes program instructions to keep the distal end of the linear motor shaft at a constant axial position, as offset by the position indicated by the linear motor shaft advancement profile, based on second control signals received from the housing position detector of the second feedback circuit so as to compensate for user movement of the device housing.
Powered drivers, intraosseous devices and methods to access bone marrow
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.
Apparatus and method to access bone marrow
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.
Method And Apparatus For Attaching A Reference Marker To A Patient
Systems and methods for attaching a reference marker to a patient in a computer-assisted image-guided surgery system. An apparatus for attaching a reference marker to a patient includes an elongated member extending between a first end and a second end, a sharp tip located proximate to the first end of the elongated member that is configured to break through a cortical surface of a bone of the patient to enable the elongated member to be advanced into the bone, an anchoring device that is extendable from the elongated member in order to anchor the apparatus within the bone and inhibit relative movement of the apparatus and the bone, and a reference marker device comprising at least one optical marker configured to enable the apparatus to be tracked using a motion tracking system.
METHOD AND APPARATUS FOR IMPROVED MESENCHYMAL STEM CELL HARVESTING
A mesenchymal stem cell harvesting system and method for increasing the efficiency of collecting and processing physiological fluids containing mesenchymal stem cells from a cavity within a patient's skeletal system. Microenvironments risk in MSC production and concentration within a cavity, for example the patient's ilium, are penetrated with a pointed instrument used to create an aperture in the hard cortical bone forming the cavity followed by the insertion of an aspiration device which extracts one or more samples of cancellous bone, bone marrow, bone marrow blood and other aspirated material. The aspirate is rinsed and may be filtered to remove unwanted material and to increase the concentration and purity of the mesenchymal stem cells in the aspirant far beyond levels formerly obtainable for use in autologous treatment of the patient.
