Appl. No.:

12/236624

Inventors:

Dylan Hushka - Chandler AZ, US
Jeffrey R. Townsend - Loveland CO, US

Assignee:

TYCO Healthcare Group LP - Mansfield MA

International Classification:

A61B 18/18

US Classification:

606 51, 606 52, 606205

Abstract:

An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end thereof that are movable about a pivot from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for grasping tissue. A movable handle is included that actuates the shaft to move the jaw members relative to one another. One or both of the jaw members are adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy to tissue held therebetween. An insulating boot is disposed on at least a portion of an exterior surface of one or both jaw members, about the pivot and at a distal end of the shaft. The insulating boot includes an inner flexible portion and an outer shell that is operably engaged with one or both of the pair of jaw members.

Abstract:

An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end thereof that are movable about a pivot from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for grasping tissue. A movable handle is included that actuates a drive assembly to move the jaw members relative to one another and one or more of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy to tissue held therebetween. An insulative material, e.g., silicone, is overmolded atop at least a portion of an exterior surface of one or both jaw members, about the pivot and the distal end of the shaft.

Abstract:

Methods, systems, and computer programs are presented for creating a secure network fabric and for adding trusted devices to an existing secure network fabric. One method includes an operation for setting a switch into a provisioning mode where the switch does not enforce secure communications. While the switch is in provisioning mode, the method performs operations including establishing a connection from the switch to a provisioning controller, sending a certificate signing request (CSR) from the switch to the provisioning controller, and receiving, from the provisioning controller, a security certificate generated by a certificate authority. The method further includes an operation for entering a lockdown mode by the switch after receiving the security certificate, where the switch, while in lockdown mode, secures communications utilizing the security certificate.
