Abstract:

The present invention provides an energy delivery device for use with a medical treatment system for the more efficacious treatment of patients during laser surgery which limits the number of uses or prevents reuse of the energy delivery device after a certain threshold limit has been reached. The energy delivery device comprises a diffusing optical fiber and a memory device having data programmed therein and being operatively connected to an energy generator the optical fiber includes a temperature sensor for generating a temperature signal in a closed loop manner. The data stored in the memory device includes a multiplicity of use parameters, usage limits, usage counts, and count limits all relating to the properties of the medical treatment system. The use parameters may include an elapsed time, a total treatment time, and a number of treatment sites. A main processor is also included for calculating a temperature from the temperature signal and for updating the use parameters in response to data received by the main processor.

International Classification:

A61B 10/02

US Classification:

600566

Abstract:

A biopsy system has a cutter defining a cutter lumen along an axis. One conduit in the system is configured to provide fluid communication along the cutter lumen axis; while another conduit in the system is configured to provide fluid communication lateral to the cutter lumen axis. The system may be operated in a variety of modes, including a sample cycle, a clear probe cycle, a cutter positioning cycle, an aspirate cycle, and a maintenance vacuum pulse cycle. The operational modes are selectable by a user. Depending on the mode selected by the user, the communication of vacuum, saline, or atmospheric air through the conduits, or the sealing of the conduits, will vary as a function of the axial position of the cutter.

International Classification:

A61B 10/00

US Classification:

600565

Abstract:

A biopsy system includes a biopsy device, a vacuum canister, a vacuum control module, and a plurality of tubes. A first tube is configured to provide an axial vacuum to the biopsy device, while a second tube is configured to provide a lateral vacuum. A third tube is configured to communicate atmospheric air to the second tube. A fourth tube is configured to communicate saline to the second tube. The vacuum canister is configured to collect fluids drawn through the first tube and the second tube. The canister has a lid with trenches formed in it for retaining the first, second, third, and fourth tubes. The lid also has engagement regions for selectively pinching each of the tubes against to prevent fluid communication through selected tubes. The canister can be removably inserted into the vacuum control module, which includes components for selectively pinching the tubes against the engagement regions.

Inventors:

Paul Ritchie - Loveland OH, US
Trevor Speeg - Williamsburg OH, US

International Classification:

A61N005/06

US Classification:

607088000, 607089000, 607093000

Abstract:

The present invention provides an energy delivery device for use with a medical treatment system for the more efficacious treatment of patients during laser surgery. An energy delivery device comprises an optical fiber and a memory device having data programmed therein. The data is specifically associated with the energy self-absorption properties of the optical fiber. This data may include a calibration parameter indicative of a self-heating characteristic of the optical fiber. The optical fiber and the memory device are operatively connected to the energy delivery device during use of the medical treatment system. The calibration parameter stored within the memory device is used by a main processor to calculate a corrected temperature value from a measured temperature at the treatment site. Thereafter, the power level of the energy generator is automatically adjusted in response to the corrected temperature value to assure that the proper energy is delivered to the human tissue through the light-diffusing section of the optical fiber. The power level is either increased or decreased to the correct power level setting for the desired temperature based on the calibration parameter.
