A laminar flow element is configured to create an ante-chamber where complete and turbulent mixing of the aerosol occurs. A radial exhaust and the laminar flow element enable laminar flow of the aerosol through the inhalation exposure chamber. | 2020-01-23 |
20200022796 | METHOD AND APPARATUS FOR FIXATION OF IMPLANTABLE DEVICES ADJACENT A BODY LUMEN - The present application relates to method and apparatus for reducing migration and rotation of implantable devices including an expandable element and an elongate portion. | 2020-01-23 |
20200022797 | IVC FILTER RETRIEVAL KIT - A surgical kit used for removing a vascular filter, particularly an Inferior Vena Cava (IVC) filter. The surgical kit includes a forceps-tool and a sheath. The forceps-tool includes a pair of interlocking-jaw members configured to grasp a hook of the vascular filter in a clamped-position. Once clamped, the sheath can be extended over a body of the vascular filter to retrieve and remove the vascular filter. | 2020-01-23 |
20200022798 | METHOD FOR ELIMINATION OF SPACE THROUGH TISSUE APPROXIMATION - Acellular tissue matrix compositions for use in tissue approximation are provided. Also provided are methods for making and using the compositions to approximate tissue. | 2020-01-23 |
20200022799 | CYLINDRICAL STRUCTURE - A tubular structure has succeeded in achieving excellent puncture resistance as well as maintenance of flexibility in a base by covering the base with a cover having excellent flexibility. The tubular structure includes a tubular base and a cover which covers the base, wherein the cover includes a copolymer containing a silicone monomer and a polymerizable monomer having a fluoroalkyl group(s) as monomer units. | 2020-01-23 |
