| 20100152616 | DEVICES AND METHODS FOR SAFELY ACCESSING BONE MARROW AND OTHER TISSUES - A device for safely accessing bone marrow and other tissues is disclosed. Such device comprises a needle assembly, a sensor mechanism, and an actuator configured to engage with the needle assembly via the sensor mechanism to advance a tissue penetrable needle through a first tissue region and into a second tissue region. In one aspect, the first tissue region is a bone cortex and the second tissue region is a bone marrow cavity. The sensor mechanism is configured to disengage the actuator from the needle once the needle has crossed the first tissue region (e.g., bone cortex) into the second tissue region (e.g., bone marrow cavity), thereby preventing the needle from advancing further into the second tissue region. In one aspect, the sensor mechanism is mechanical and comprises a pin assembly comprising a spring-loaded pin that extends through the needle. The pin assembly is configured such that advancement of the distal tip of the spring-loaded pin past the distal tip of the needle causes the actuator to disengage from the needle. The actuator is a rotatable actuator. A catheter-based embodiment of the device can be inserted in body passageways to access tissue internally within the body. | 06-17-2010 |
| 20110054350 | BIOPSY APPARATUS HAVING A TISSUE SAMPLE RETRIEVAL MECHANISM - A biopsy apparatus includes a biopsy probe having a biopsy cannula and a sample basket arranged coaxially about a longitudinal axis. The sample basket is movably disposed relative to the biopsy cannula along the longitudinal axis from a tissue harvesting position to a tissue sample retrieval region. The sample basket has a sample notch formed as an elongate recessed region for receiving a tissue sample. A tissue sample retrieval mechanism includes a sample collection tank configured for removable insertion into a sample tank receptacle. The sample tank receptacle permits movement of the sample collection tank in a direction perpendicular to the longitudinal axis and prohibits movement of the sample collection tank in a direction along the longitudinal axis. The sample collection tank is configured to retrieve the tissue sample directly from the sample notch as the sample basket is moving along the longitudinal axis at the tissue sample retrieval region. | 03-03-2011 |
| 20110077552 | BIOPSY DEVICE WITH VARIABLE SPEED CUTTER ADVANCE - A biopsy device having a translating and rotating cutter is disclosed. The translational speed of the cutter is varied using a variable pitch member. The variable pitch member can include a shaft having a relatively coarse threaded portion for rapid cutter advance and a relatively finer threaded portion for cutter advance during tissue severing. | 03-31-2011 |
| 20110152717 | APPARATUS FOR INSERTING NEEDLE - Provided is an apparatus for inserting a needle capable of obtaining automation of tissue sample collection or drug injection and operation stability by applying a link mechanism between a needle inserted into a specific part of a human body and a power source for providing a drive force. The apparatus includes a needle unit inserted into a human body, a drive unit configured to provide a drive force to the needle unit such that the needle unit reciprocates between an insertion position at which the needle unit is inserted into the human body and a withdrawal position at which the needle unit is withdraw to the outside of the human body, and a guide unit including a plurality of guide links each having at least two links relatively rotated by the drive force of the drive unit and radially disposed around the needle unit, and configured to guide the needle unit such that the needle unit translates between the insertion position and the withdrawal position in a longitudinal direction of the needle unit. | 06-23-2011 |
| 20110208090 | Spring Loaded Biopsy Device - A biopsy device comprises a body, a needle, a cutter, and a motor. The cutter is translatable within the needle to sever tissue protruding through a lateral aperture formed in the needle. A cutter actuation mechanism comprises a split nut, a cutter retraction nut, and a resilient member. The resilient member is configured to bias the cutter distally. The motor is operable to rotate the split nut, which in turn translates the cutter retraction nut proximally in order to translate the cutter proximally and compress the resilient member. Once the cutter reaches a proximal position, segments forming the split nut separate to disengage the cutter retraction nut, thereby allowing the resilient member to translate the cutter distally. In addition, the motor rotates the cutter as the cutter translates distally. The motor may selectively engage either the split nut or the cutter for rotation. | 08-25-2011 |
| 20140358032 | BIOPSY DRIVER ASSEMBLY HAVING A CONTROL CIRCUIT FOR CONSERVING BATTERY POWER - A biopsy driver assembly includes a biopsy driver housing. An electrical assembly is coupled to the biopsy driver housing. The electrical assembly includes at least one electrical drive configured for drivably engaging a biopsy probe assembly. A battery is coupled to the biopsy driver housing. A control circuit is coupled to the biopsy driver housing. The control circuit is electrically coupled to the battery and to the electrical assembly. The control circuit has a motion detector, a timer circuit and a battery dwell circuit. The control circuit is configured to conserve the battery by providing electrical power only to the motion detector after a predetermined time following a last detected physical movement of the biopsy driver assembly and to provide electrical power from the battery also to the electrical assembly when a physical movement of the biopsy driver assembly is detected. | 12-04-2014 |
| 20150073301 | TISSUE HANDLING SYSTEM WITH REDUCED OPERATOR EXPOSURE - A tissue handling system includes a biopsy device having an invasive unit with tissue-receiving and tissue-severing components being capable of harvesting and bringing at least one tissue sample to a point outside the body of a patient. The tissue handling system further includes a tissue collecting device adapted to be brought in detachable operative engagement with the tissue-receiving components of the biopsy device to remove the at least one tissue sample. Additionally, the tissue handling device comprises a tissue storage container configured to receive the at least one tissue sample, the entire tissue collecting device, or the part of the collecting device that contains the at least one tissue sample. The tissue storage container further is configured to receive a volume of preserving agent. The tissue handling system also comprises a vessel including the preserving agent adapted to be gas-tightly mated or coupled to the tissue storage container. | 03-12-2015 |
| 20150141869 | DEVICES, SYSTEMS, AND METHODS FOR NAVIGATING A BIOPSY TOOL TO A TARGET LOCATION AND OBTAINING A TISSUE SAMPLE USING THE SAME - A biopsy tool includes an elongated flexible body, a sensor assembly, and a screw member. The sensor assembly is disposed within the elongated flexible body towards the distal end thereof. The sensor assembly includes a location sensor(s) configured to enable detection of a location of the sensor assembly. The screw member is coupled to the distal end of elongated flexible body, extends distally from the elongated flexible body, and is positioned distally of the sensor assembly. The screw member defines a helical configuration having a hollow interior and is configured for simultaneous rotation relative to tissue and advancement into tissue to obtain a tissue sample. | 05-21-2015 |
