  • TROCAR FOR IMPROVED FLUID PRESSURE MANAGEMENT DURING ENDOSCOPIC SURGERY
    Publication number: 20170360476
    Abstract: A trocar for arthroscopy and other endoscopic surgeries is provided, including a diaphragm seal, in which the assembly as a whole provides adequate insufflation of the body compartment during a procedure, while limiting or eliminating the leakage of insufflation fluid from the rear of the trocar, thus maintaining adequate insufflation pressure management. The design, placement, and spacing associated with said diaphragm seal provides an enhanced interface between the diaphragm opening and a surgical instrument inserted through such opening to gain access to the body compartment of a surgical patient.

  • Perivascular pressure sensor and sensing system
    Patent number: 8231538
    Abstract: An embodiment of the invention is an in-vivo blood pressure sensor device including a strain transducer and flexible biocompatible material that carries the strain transducer. The flexible biocompatible material is configured to encircle the outside of a blood vessel when surgically installed. A preferred embodiment in-vivo blood pressure sensor device of the invention includes a strain transducer carried by a flexible biocompatible ring that is configured to be surgically installed to encircle a blood vessel. The device also includes passive circuitry encased in biocompatible material for sensing strain in the strain transducer and for providing data to an external reader. The passive circuitry is also configured to be surgically installed in a subject.
