20230210554 · 2023-07-06 ·

A device suitable for use in a body lumen and comprises an elongated control member having a distal and a proximal end, and a radially expansible member disposed at or near the distal end and adapted for collection and/or shearing of matter (i.e. thrombus) from a wall of the body lumen (i.e. a vein or an artery). The radially expansible member has a proximal end and a distal end and is adjustable between a contracted orientation and an expanded orientation. The elongated control member comprising a proximal arm connected at or adjacent to the proximal end of the radially expansible member and a distal arm connected at or adjacent to the distal end of the radially expansible member such that movement of one arm relative to the other arm effects adjustment of the diameter or radial strength of the radially expansible member. The device comprises a control mechanism operatively connected to both arms and adapted to provide resistance to the movement of one arm relative to the other. The control mechanism may be a biasing means, a brake means, or both.

PROCESS FOR PERCUTANEOUS OPERATIONS

A method is described for performing a percutaneous operation on a patient to remove an object from a cavity within the patient. The method includes advancing a first alignment sensor into the cavity through a patient lumen. The first alignment sensor provides its position and orientation in free space in real time. The alignment sensor is manipulated until it is located in proximity to the object. A percutaneous opening is made in the patient with a surgical tool, where the surgical tool includes a second alignment sensor that provides the position and orientation of the surgical tool in free space in real time. The surgical tool is directed towards the object using data provided by both the first and the second alignment sensors.

Cooled burr surgical instruments

Featured is a surgical instrument including an end effector such as a rotating cutting implement and a heat transfer mechanism such as a cooling device, such as can include a phase change device, such as can be configured to absorb heat energy during the use of such a rotating cutting implement. The heat transfer mechanism can be configured so the absorbed heat energy is communicated to an external heat sink. Such a heat transfer mechanism can include a heat pipe, e.g., a scintered or wick type heat pipe. The heat energy is absorbed at one end of the heat pipe to minimize the potential for damage to the tissue and the like at and/or about the surgical site. Also featured are a surgical apparatus embodying such a surgical instrument and surgical or medical methods or procedures for manipulating, rotatably cutting, grinding, abrading or debriding tissue, bone or other structures or components of a mammalian body using such surgical instruments or surgical apparatus.

The mentioned laparoscopic device contains a motor inside the hand unit, motor drive unit, cycle unit, cycle control unit and trigger and the shaft part contains aspiration channel, washing channel, the shaft enabling the blade movement and blade unit in the conical slot at the end part of the same shaft, which rotates transversely to the conical slot.

DEVICES AND METHODS FOR REMOVING MATERIAL FROM A PATIENT

A containing element is used to capture material in a blood vessel for removal. The containing element is advanced through the blood vessel or a catheter in a constricted configuration. A control body is coupled to the containing element which assists moving the containing element. In some embodiments, the containing element is used for restricting blood flow within a vessel.

SURGICAL PROBE WITH INDEPENDENT ENERGY SOURCES

An energy source is offset from an elongate probe axis with an extension. The amount of offset of the energy source can be controlled by varying an amount of offset of the extension. The energy source rotated and translated at the offset distance to resect tissue. In some embodiments, the probe is configured to receive a second treatment probe comprising a second energy source, in which the second energy source is rotated and translated relative to the first treatment probe, which can improve positional accuracy and stability. The energy source and the extension can be coupled to a linkage to offset the energy source, and to translate and rotate the energy source with varying amounts of offset. The linkage can be coupled to a processor and one or more of the energy source moved in accordance with a treatment profile.
