1. A shock absorber leash comprising in combination,
at its proximal end,
means for grasping used for holding said shock absorber leash when dealing with an animal;
and at its distal end,
means for attaching for fastening to the animal;
an elongated strap subassembly including
means for strapping comprising a strap of non elastic, continuous structure for connecting said means for grasping with said means for attaching;
means for length adjusting including an elastic strip having its ends attached to a means for buckling used for adjusting a length of said elastic strip, said means for length adjusting being interposed laterally between the ends of a segment of said strap, said segment of said strap being provided adjacent to its ends with a first and second rings and forming a loop when said means for length adjusting is not completely stretched; said means for length adjusting being detachable, when required, from a remaining of said shock absorber leash by using said means for buckling and a free passage of said elastic strip through said first and second ring.
2. The shock absorber leash, as defined in claim 1, wherein
said means for grasping includes a tubular handle incorporating
a tubular element made to resist deformation and breaking;
a sleeve in which said tubular element is inserted; and
a pair of grommets, press fitted into extremities of said tubular element, so that a translation of said sleeve along said tubular element is prevented;
said means for attaching comprising a clasp that incorporates
a bracket pivotally joined to said means for strapping;
a hook pivotally joined to said bracket; and
a spring operated element for closing said hook;
said means for strapping having an end of said strap, which after leaving said means of grasping, passes through the first ring and is folded back upon itself and, then, superposed and permanently joined by stitching to a remaining of the strap, thus forming a first stitch; another end of the strap, after leaving said means for grasping and participating, as a superposed component, in said first secured connection, extends into said segment, respectively said loop, then is doubled back upon itself and, after passing through said second ring, returns and is superposed on and permanently joined by said conventional means for securing to said remaining of said strap, thus forming a second secured connection; subsequently, said strap first passes through an adjustable buckle for adjusting an effective length of said strap, second, passes through said bracket of said clasp, third, passes again through said adjustable buckle and, finally, through a first pull ring; after passing through the latter, said strap is doubled back and permanently joined by said conventional means for securing to said remaining of said strap, thus forming a third secured connection;
said means for length adjusting including said elastic strip and said means for buckling, the latter being a cam-buckle of double bar type, one end of said elastic strip entering from one side of a bar and exiting from another side of said bar to form together a pair of said elastic strips, superposed, the latter traversing said first and second rings, then returning to said cam-buckle for passing adjacently another bar of said cam-buckle for exiting from the latter; said elastic strip, impliedly said pair of said elastic strips, superimposed, being so dimensioned in length as to bias said ends of said segment toward each other,
whereby upon application of a sharp, corrective pull on said shock absorber leash by an animal trainer, said elastic strip elongates, while upon relaxation of said shock absorber leash, said elastic strip shortens and once again places said ends of said segment in their normal spaced relation relative each other.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
We claim:
1. A scaffold for promoting restoration of a tissue when implanted at an anatomical site in a patient, comprising:
at least a portion of a devitalized mammalian parenchymatous tissue combined with a target mammalian cell population, wherein the combined tissue and cell population is sized and shaped for implantation at the anatomical site in the patient remote from the tissue requiring restoration.
2. The scaffold of claim 1 wherein the devitalized mammalian tissue further comprises a basement membrane.
3. The scaffold of claim 1 wherein the devitalized tissue is spleen.
4. The scaffold of claim 1 wherein the devitalized tissue comprises kidney.
5. The scaffold of claim 1 wherein the devitalized tissue comprises lymph node.
6. The scaffold of claim 1 wherein the devitalized tissue comprises an allogeneic tissue source.
7. The scaffold of claim 1 wherein the devitalized tissue comprises an autogeneic tissue source.
8. The scaffold of claim 1 wherein the devitalized tissue comprises an xenogeneic tissue source.
9. The scaffold of claim I wherein the stem cell population is introduced into the tissue.
10. The scaffold of claim 1 wherein the stem cells comprise autogeneic stem cells.
11. The scaffold of claim 1 wherein the stem cells comprise allogeneic stem cells.
12. The scaffold of claim 1 wherein the stem cells comprise xenogeneic stem cells.
13. The scaffold according to claim 1 wherein the tissue undergoing restoration comprises an endocrine tissue.
14. The scaffold of claim 13 wherein the devitalized parenchymatous tissue comprises spleen.
15. The scaffold of claim 13 wherein the devitalized parenchymatous tissue comprises kidney.
16. The scaffold of claim 13 wherein the devitalized parenchymatous tissue comprises pancreas.
17. The scaffold of claim 13 wherein the target cell population comprises mammalian endocrine cells.
18. The scaffold of claim 17 wherein the mammalian endocrine cells comprise pancreatic islet cells.
19. The scaffold of claim 17 wherein the mammalian endocrine cells comprise pituitary cells.
20. The scaffold of claim 17 wherein the mammalian endocrine cells comprise thyroid cells.
21. The scaffold of claim 17 wherein the mammalian endocrine cells comprise cells from the adrenal gland.
22. The scaffold of claim 13 wherein the devitalized parenchymatous mammalian tissue is autogeneic.
23. The scaffold of claim 13 wherein the devitalized parenchymatous mammalian tissue is allogeneic.
24. The scaffold of claim 13 wherein the devitalized parenchymatous mammalian tissue is xenogeneic.
