Medical devices are disclosed. For example, a medical device includes an elongated member. The medical device includes a hole forming surface along a portion of the elongated member. The medical device includes an open cell element in physical communication with the elongated member. The open cell element is configured to house at least a first portion of a biocompatible substance.

A clot capture module can include a housing, a chamber inside the housing, a window, and a filter. The window permits visual inspection of a clot inside the chamber. The clot can access the chamber via an incoming flow path configured to direct blood from an aspiration catheter to an upstream surface of the filter. An aspiration control valve can block the flow of incoming aspirated blood until actuated to permit inflow of aspirated blood. An outgoing flow path can direct blood from a downstream surface of the filter to a remote vacuum canister.

An apparatus for treating skin has a console with a user input device and a handpiece assembly. The handpiece assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handpiece assembly. A manifold system is coupled to the console and controlled by the user input device. The manifold system is configured to hold releasably a plurality of fluid sources and deliver fluid from at least one of the plurality of fluid sources to the handpiece assembly.

An ultrasonic device may include an electromechanical ultrasonic system defined by a predetermined resonant frequency, in which the system may include an ultrasonic transducer coupled to an ultrasonic blade. A method of estimating a state of an end effector of the ultrasonic device may include applying a drive signal defined by a magnitude and a frequency to the ultrasonic transducer, sweeping the frequency of the drive signal from below a first resonance to above the first resonance of the electromagnetic ultrasonic system, measuring and recording, impedance/admittance circle variables R.sub.e, G.sub.e, X.sub.e, and B.sub.e, comparing, the measured impedance/admittance circle variables R.sub.e, G.sub.e, X.sub.e, and B.sub.e to reference impedance/admittance circle variables R.sub.ref, G.sub.ref, X.sub.ref, and B.sub.ref, and determining, a state or condition of the end effector based on the result of the comparison. An electromechanical ultrasonic system may include a control circuit to effect the method.

A cutting instrument comprising: an outer tube comprising a distal end and a proximal end; an inner tube rotatably disposed within said outer tube, said inner tube comprising a distal end, a proximal end and a region intermediate said distal end and said proximal end, said region comprising a plurality of slits formed in said inner tube so as to render said region of said inner tube flexible; and a bellows disposed adjacent to said plurality of slits so as to render said region of said inner tube fluid-tight.

A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal. The working head may be operated to separate and move away from the guide wire to come within a closer proximity of the obstructive material to more effectively remove it from the vessel.

The cannula (1) comprises a tube (2) with a front end (4) at which there is provided at least one suction opening (10), and with a back end (3) intended to be connected to a source of vacuum; in the tube (2) there being defined at least one longitudinal flow conduit (8, 9) for the aspirated material; and an imaging apparatus (11, 12) capable of supplying first signals or data allowing the generation of a visual representation of the environment in close proximity to the front end of the tube (2) of the cannula (1) down to a first depth or distance, and second signals or data allowing the generation of a visual representation of the environment around the front end of the tube (2) of the cannula (1) down to a second depth or distance, greater than the said first depth or distance.

An apparatus and method for performing painless bone marrow biopsy that requires only a single procedural pass to the biopsy bone site is disclosed. The biopsy device combines dermatotomy, anesthesia and marrow specimen extraction functionality and inherently aligns the bone drilling site with the site of anesthetic delivery by incorporating a transport channel that may be used for anesthetic delivery, into the biopsy needle used for bone access and bone marrow sample retrieval. The biopsy device also discloses a right angle drill interface and multiple side-access ports for aspiration and anesthetic syringe attachments. A novel syringe/plunger system comprising vacuum tube fitted plungers for quick transfer of marrow specimen sample without requiring a second non-sterile assistant is also disclosed.

A treatment device includes: a probe including a treatment portion that performs treatment to a treatment target portion by transmission of ultrasonic vibration; a first sheath having a first edge and enclosing a periphery of the probe; a second sheath having a second edge and enclosing a periphery of the first sheath; a suction path including a suction opening between the first edge and the second edge and provided between the first sheath and the second sheath; and a connection part communicating with the suction path and connected to a suction source.

Various exemplary methods, systems, and devices for initializing a surgical tool are provided. In general, a surgical tool can include an end effector, an elongate shaft, and a wrist that couples the end effector to a distal end of the shaft. The wrist can be configured to facilitate movement of the end effector relative to the shaft. The surgical tool can include multiple flexible members configured to move, either individually or as a group including any plural number of the flexible members, to cause the movement of the end effector relative to the shaft by pivoting at the wrist. The movement of the end effector can include movement between an unarticulated position and an articulated position. The surgical tool can also include one or more homing members configured to be selectively actuated to force the end effector into the unarticulated position.
