Abstract
A cell transplantation device is used to place a graft containing cells into a target region in a living body. The cell transplantation device includes a needle extending in one direction, and a filter unit made of a fibrous member. The needle has a flow channel defined therein and an opening at the tip of the needle. The filter unit is disposed at an intermediate position in the flow channel and configured to retain a graft between the filter unit and the opening when a liquid material containing the graft enters the flow channel through the opening.
Claims12
A cell transplantation device configured to place a graft containing cells into a target region in a living body, the cell transplantation device, comprising:
- a needle extending in one direction, the needle having a flow channel defined therein and an opening at a tip of the needle;
- and
- a filter unit made of a fibrous member, the filter unit being disposed at an intermediate position in the flow channel and configured to retain the graft between the filter unit and the opening when a liquid material containing the graft enters the flow channel through the opening.
A cell transplantation device configured to place a graft containing cells into a target region in a living body, the cell transplantation device, comprising:
- a needle extending in one direction, the needle having a flow channel defined therein and an opening at a tip of the needle, wherein
- a region surrounded by a side wall of the flow channel from an intermediate position in the flow channel to the opening serves as a storage portion that stores a liquid material entering through the opening while allowing the graft contained in the liquid material to be retained in the region, and
- a length of the storage portion in the extending direction of the needle is larger than a maximum width of the storage portion in a direction perpendicular to the extending direction of the needle.
A cell transplantation device configured to place a graft containing cells into a target region in a living body, the cell transplantation device, comprising
- a plurality of needles extending in a first direction, wherein
- the plurality of needles include
- at least one needle having a tip whose position is not aligned with that of others in the first direction, and
- a plurality of transplantation needles each having an opening in a tip region, the opening being provided as an inlet port through which the graft is taken into the needle and an outlet port through which the graft is ejected toward the target region.
A cell transplantation system, comprising:
- a cell transplantation device configured to place a graft containing cells into a target region in a living body, the cell transplantation device including a needle extending in one direction, the needle being configured to collect the graft through an opening formed at a tip of the needle and store the graft in the needle;
- and
- a detector that detects when the graft is held by the needle.
