A medical apparatus remanufacturing method includes: disassembling a housing including a first housing and a second housing. The first housing can include a boss that is press-fitted to a boss hole of a press-fitted portion of a second housing to form an assembled state in which the first housing and the second housing are assembled to each other. The housing is disassembled by changing a temperature of at least one of the boss or the press-fitted portion to decrease a contact surface pressure between the boss and the boss hole, and removing the boss from the boss hole to release the assembled state.

A robotic catheter system including a first drive mechanism configured to interact with an elongated medical device to cause the elongated medical device to move along its longitudinal axis. A controller provides a signal to a motor to move the first wiping surface toward the longitudinal axis when the elongated device is being withdrawn from a patient.

In an apparatus for directing a laser beam to a dental treatment area, where the apparatus includes a hand piece having an optical subsystem including a turning mirror for directing a laser beam to a treatment area via an orifice of the hand piece, a fluid supply subsystem creates a fluid flow within the hand piece proximate the turning mirror so as to mitigate contamination thereof.

There is provided a method (500) of treating an optical waveguide. The method comprises applying (502) the volume of ferrofluid to the optical waveguide, and applying (504) a magnetic field to the volume of ferrofluid to move the volume of ferrofluid at least partially along a length of the optical waveguide. A personal care device and a system are also disclosed.

A dismantlable medical instrument including first, second and third components, a first bayonet connection for releasable mechanical connection of the third and second components, and a second bayonet connection for releasable mechanical connection of the third and first components. In a first predetermined position of the third component relative to the second component, the third component is not connected to the second component. In a second predetermined position of the third component relative to the second component, the third component is mechanically connected to the second component by the first bayonet connection, and the second and third components are not connected to the first component. In a third predetermined position of the third component relative to the second and first components, the third component is mechanically rigidly connected to the second component by the first bayonet connection and to the first component by the second bayonet connection.

Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a shaft having a distal end and a proximal end; a monopolar knife assembly attached to the distal end of the shaft, the monopolar knife assembly comprising a knife; a handle attached to the proximal end of the shaft; wherein the shaft comprises a flexible portion and an articulating portion, wherein the flexible portion extends distally from the handle and the articulating portion extends distally from the flexible portion; wherein at least one articulation cable extends from the handle to the articulating portion, such that when tension is applied to the at least one articulation cable, the articulating portion deflects; wherein an actuation element extends through the shaft from the handle to the knife, such that when the actuation element is moved, the knife is moved; and wherein the actuation element transmits electrical power from the handle to the knife.

A catheter has a composite and segmented construction in a distal section that includes deflectable members and support member arranged in alternating sequence, with each support member carrying a ring electrode and the deflectable members being flexible to allow deflection of the distal section as a whole. Carried on an outer surface of the support member is a coil location sensor. The distal section is configured with a distal irrigation fluid path extending axially through the deflectable members and the support members to deliver irrigation fluid to the ring electrode and the tip electrode. A method of constructing a catheter includes building a section of the catheter from the inside out by mounting the support members on a tubing at predetermined locations and filling gaps in between with a more flexible material to form the deflectable members by extrusion segments or injection molding over assembled components internal to the catheter.

The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.
