Abstract
A method and device for implanting large diameter objects subcutaneously or into the peritoneal cavity of bovines employs a beveled, puncturing, but substantially non-incising trocar.
Claims14
A device for the intraperitoneal or subcutaneous implantation of large, in the range of about 8 to about 15 mm, diameter size-invariant objects into a bovine, comprising:
- a tube of moldable plastic which itself functions as a trocar having an outside diameter of less than about 25 mm and having a first portion of its length which extends from hide to intraperitoneal cavity adjacent the left paralumbar fossa in a bovine, said first portion having an inside diameter in the range of about 8 to about 15 mm;
- the tube having a first end and a second end, the first end of the tube having a non-hide-incising tip which absent any other trocar penetrates tissues underlying an incision in the hide and which punctures the peritoneum, the tube having adjacent the first end thereof means for releasably retaining the large diameter objects in the tube while the tube is inserted into an incision in the bovine's hide and having adjacent the second end thereof a seal for completing enclosure of contents of the tube.
An article of manufacture comprising:
- a plastic tube which itself functions as a trocar having a non-hide-incising tip at a first end which absent any other trocar penetrates bovine tissues underlying an incision in hide of a bovine and punctures the peritoneum and penetrates into the intraperitoneal cavity of the bovine;
- a plastic sheath enclosing a first portion of the tube adjacent the first end, the first portion having a length which extends from left paralumbar fossa of a bovine into the intraperitoneal cavity;
- retaining means adjacent the first end for releasably retaining objects within the tube after the sheath is removed;
- the objects within the tube being one or more osmotically-driven pumps having an outside diameter of about 8 to about 15 mm for delivery of a beneficial agent;
- and
- a seal adjacent the second end of the tube for completing sterile or low bioburden enclosure of contents of the tube.
