US Classification:

606 15, 606 13, 606 14, 606 16, 607 89

Abstract:

A method of controllably heating the annulus of an intervertebral disc is disclosed. The method comprises the steps of forming an access channel through the annulus of an intervertebral disc while avoiding the nucleus of the intervertebral disc, inserting a light-emitting diffuser into the annulus, and activating the light-emitting diffuser to emit diffuse light while maintaining the light-emitting diffuser within the access channel to raise the temperature of the annulus to a value sufficient to cause a change in the characteristics of the annulus.

International Classification:

A61B 18/22

US Classification:

606 16, 2 10

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.

Abstract:

A method for repairing or modifying an area of a patient's anatomy that comprises directing at least a portion of a scanning beam assembly to an area of a patient's anatomy, applying a radiation-responsive agent to portion of the anatomy, and exposing the radiation-responsive agent to radiation directed onto the agent by the reflector to cause the agent to therapeutically interact with the site. The scanning beam assembly including a radiation source capable of emitting radiation, a reflector that receives the radiation from the radiation source to direct the radiation onto the anatomy, wherein the reflector oscillates in at least two directions to create a scan of the anatomy, a detector to detect radiation returned from the anatomy, and a controller to convert the detected radiation into a displayable anatomy image.

Abstract:

A system for examining an area of a patient's anatomy that comprises a probe capable of fluorescing, and a scanning beam assembly that scans the probe with a beam of excitation radiation and detects the probe's fluorescence. The scanning beam assembly including a radiation source capable of emitting one or more wavelengths of radiation that are capable of exciting the probe and causing the probe to fluoresce, a scanning device that directs the radiation onto a field-of-view to create a scan of the field-of-view, a detector to detect radiation returned from the field-of-view, and a controller to convert the detected radiation into a displayable fluorescence image.
