Abstract:
An assistive sample collection and storage assembly for collecting, transferring and storing a biological sample includes a sample collection device having a first portion and a second portion. The first portion is configured to receive a sample collection member. The assembly includes a sample storage device comprising a sample substrate configured to receive at least a portion of the biological sample from the sample collection member. The assembly is configured to exist in a first state and a second state. The sample collection member is disposed at a determined distance from the sample substrate in the first state. At least a portion of the sample collection member is in physical contact with at least a portion of the sample substrate in the second state. The sample collection member is configured to apply a determined amount of contact force between the collection member and the sample substrate in the second state of the assembly.
Abstract:
A coupling device configured to form a sample access assembly is provided. The sample access assembly is configured to house a sample. The coupling device includes a heating component and a separating component. Further, the separating component is configured to separate portions of first and second containers that form first and second compartments of the sample access assembly. Moreover, the heating component is configured to heat at least a portion of the sample.
Abstract:
The present disclosure relates to the manufacture and use of a non-rigid breast compression paddle, such as a compression paddle having a mesh material forming the primary interface with patient tissue. In certain implementations, an automatic feedback driven approach may be used in conjunction with such a compression paddle for compressing breast tissue.
Abstract:
Embodiments of the disclosure comprise a vision-based robotic manipulation system that identifies, singulates, and removes an individual surgical instrument from a cluttered environment. A computer-vision algorithm incorporated with the system is robust against optical challenges such as changing light conditions, specularities, and inter-reflections among various surgical instruments. The system estimates 2D pose (as opposed to a more challenging 3D pose) using a camera with normal room lighting to identify each object, including its specified data matrix barcode; and incorporates the use of a robotic arm with a compliant electromagnetic gripper to handle objects having large shape variance. The system can then relocate the objects as desired. The robot manipulator is utilized in hospital and research settings, manufacturing, and sterile environments.
Abstract:
A heating assembly for a bioreactor is disclosed. The heating assembly includes a holder having a plurality of segments coupled to each other to define a unitary structure and a heating component coupled to at least one segment of the plurality of segments. The unitary structure includes a top end, a bottom end, and a side wall. The side wall extends between the top end and the bottom end and along a circumferential direction of the heating assembly to define a cavity. At least a portion of the unitary structure has a gradually varied perimeter along a direction perpendicular to a plane which intersects the side wall and is parallel to the top end and the bottom end.
Abstract:
A method for separating and collecting cell-free plasma by finger stick that minimizes contamination with genomic DNA from a donor. The method comprising placing a tourniquet on one of the digits of the donor's finger to apply pressure, lancing the digit to create an incision in the digit, and collecting blood from the incision from the incision site. The collected blood is placed on a separation membrane wherein the separation membrane is in contact with a collection membrane and both the separation and collection membrane are inserted into a substrate configured to provide overlap between the membranes. A kit and instructions for carrying out the method is also provided.

Abstract:
An ultrasound scan probe and support mechanism are provided for use in a multi-modality mammography imaging system, such as a combined tomosynthesis and ultrasound imaging system. In one embodiment, the ultrasound components may be positioned and configured so as not to interfere with the tomosynthesis imaging operation, such as to remain out of the X-ray beam path. Further, the ultrasound probe and associated components may be configured to as to move and scan the breast tissue under compression, such as under the compression provided by one or more paddles used in the tomosynthesis imaging operation.
Abstract:
An apparatus for balancing a statically unbalanced system, particularly useful in balancing X-ray and mammography systems having an X-ray source and detector mounted to a rotational arm, includes a spring mechanism which synchronizes the activation of the spring mechanism with the rotation of the arm of the mammography system. The balancing system reduces the amount of torque necessary to rotate the arm and decreases the overall inertia of the system by eliminating the need for counterweights to maintain balance of the system.
