Tissue transplantation method and apparatus
View Patent ↗A system in accordance with embodiments of the present invention includes a cannula interconnected to a washing reservoir by a flexible conduit. The washing reservoir has an outlet that is connected to the inlet of a tissue collection reservoir. Washed tissue can be removed from the washing reservoir by tipping or otherwise causing the outlet of the washing reservoir to be covered by washed tissue. Tissue collected in the tissue collection reservoir can be readied for injection into a body by removing an inner or filter chamber from an outer chamber and blocking holes in the body of the inner chamber to use the inner chamber as part of a syringe.
1. A system, comprising:
a tissue washing reservoir;
an inlet;
an outlet, wherein the inlet is separate from the outlet;
a tissue collection reservoir, including:
an inlet;
an outlet;
an outer chamber;
an inner chamber substantially within the outer chamber, including:
a body portion, wherein the body portion defines a tissue collection volume in communication with the tissue collection reservoir inlet;
a plurality of holes formed in the body portion;
a washed material conduit, wherein the washed material conduit interconnects the outlet of the tissue washing reservoir to the inlet of the tissue collection reservoir, and wherein the washed material conduit is in communication with an interior of the tissue collection volume via the inlet of the tissue collection reservoir;
a mount operable to interconnect the tissue collection reservoir to a support, wherein the inlet of the tissue collection reservoir is at a top of the tissue collection reservoir when the mount is interconnected to the support, wherein the outlet of the tissue collection reservoir is at a bottom of the tissue collection reservoir when the tissue collection reservoir mount is interconnected to the support;
a vacuum source;
a vacuum source conduit interconnecting the vacuum source to the outlet of the tissue collection reservoir.
2. The system of claim 1 , further comprising:
a cannula;
a flexible cannula conduit, wherein the cannula conduit interconnects the cannula to the inlet of the tissue washing reservoir.
3. The system of claim 1 , wherein the tissue washing reservoir further includes a lid, and wherein the inlet and the outlet of the tissue washing reservoir are formed in the lid.
4. The system of claim 3 , wherein the inlet and the outlet of the tissue washing reservoir are formed in opposite halves of the lid.
5. The system of claim 1 , further comprising:
a mounting platform operable to hold the tissue collection reservoir and the tissue washing reservoir in a desired orientation.
6. The system of claim 1 , further comprising:
a cannula;
a flexible cannula conduit, wherein the cannula conduit interconnects the cannula to the inlet of the tissue washing reservoir;
a liquid irrigant in the tissue washing reservoir.
7. A system, comprising:
a tissue washing reservoir;
an inlet;
an outlet;
a tissue collection reservoir, including:
an inlet;
an outlet;
an outer chamber;
an inner chamber substantially within the outer chamber, including:
a body portion, wherein the body portion defines a tissue collection volume in communication with the tissue collection reservoir inlet;
a plurality of holes formed in the body portion;
a washed material conduit, wherein the washed material conduit is operable to interconnect the outlet of the tissue washing reservoir to the inlet of the outer chamber of the tissue collection reservoir;
a mount operable to interconnect the tissue collection reservoir to a support, wherein the inlet of the tissue collection reservoir is at a top of the tissue collection reservoir when the mount is interconnected to the support, wherein the outlet of the tissue collection reservoir is at a bottom of the tissue collection reservoir when the tissue collection reservoir mount is interconnected to the support;
a vacuum source;
a vacuum source conduit interconnecting the vacuum source to the outlet of the tissue collection reservoir; and
an inner chamber sleeve operable to seal the plurality of holes in the body of the inner chamber.
8. A system, comprising:
a tissue washing reservoir;
an inlet;
an outlet, wherein the inlet is separate from the outlet;
a tissue collection reservoir, including:
an inlet;
an outlet;
an outer chamber;
an inner chamber substantially within the outer chamber, including:
a body portion, wherein the body portion defines a tissue collection volume in communication with the tissue collection reservoir inlet;
a plurality of holes formed in the body portion;
a washed material conduit, wherein the washed material conduit interconnects the outlet of the tissue washing reservoir to the inlet of the tissue collection reservoir, and wherein the washed material conduit is in communication with an interior of the tissue collection volume via the inlet of the tissue collection reservoir, wherein the plurality of holes of the inner chamber are distributed such that a greater percentage of the area of the body portion towards an inlet to the inner chamber comprises holes than towards a distal portion of the inner chamber.
