A sheath for producing a fully sealed access to the interior of a vessel of an animal or human body comprises a base sheath having a tubular body defining a pass-through channel. The base sheath is adapted to be inserted into the vessel through a vessel aperture. A wall of the tubular body of the base sheath has a through channel. This channel extends in the wall from the distal end towards the proximal end. The channel can be present separately from the pass-through channel of the base sheath or can form a sideways extension of the pass-through channel, at least at the distal end. Such through channel is adapted to conduct blood from the vessel to the proximal end of the sheath when the sheath has been inserted into a vessel.

Sheath assembly for the insertion of a cord-shaped element, comprising an introducer sheath, and an auxiliary sheath for insertion into the introducer sheath together with the cord-shaped element. In some examples, the auxiliary sheath has a housing configured to detachably couple to the introducer sheath housing, and to detachably fasten the cord-shaped element with respect to the auxiliary sheath housing.

Methods and systems for selection of dosimetry levels and sphere amounts of radioactive compounds for use in a radioembolization procedure for procedure planning may include inputting activity parameter information into a dosimetry portal of a dosimetry selection tool; determining a customized activity based on the activity parameter information and one or more customized activity algorithms; generating one or more sphere amount and dosage recommendations based on the customized activity and one or more dosimetry selection algorithms; selecting one of the one or more sphere amount and dosage recommendations as a selected sphere amount and dosage recommendation; and generating a radioactive compound order for the radioembolization procedure based on the customized activity and the selected sphere amount and dosage recommendation.

A method for replacing a first sheath, whose distal end is positioned inside a vessel and whose proximal end is positioned outside the skin of a patient, with a second sheath may involve inserting a dilator over a guidewire and into the first sheath until a distal end of the dilator and a distal end of the guidewire are positioned inside the vessel. The dilator may be hubless or include a removable hub. The method may further involve removing the first sheath, thereby leaving only the dilator and the guidewire in place. After removing the first sheath, a second sheath may be passed over the dilator and the guidewire until the distal end of the second sheath is positioned inside the vessel. The method may further involve removing the dilator and the guidewire, leaving only the second sheath in place.

Endovascular drug delivery systems and methods are disclosed herein for delivering a therapeutic agent to the intracranial subarachnoid space of a patient, and/or deploying an endovascular drug delivery device distal portion in the intracranial subarachnoid space and a portion of the drug delivery device body in a dural venous sinus such that a therapeutic agent is delivered from the deployed drug delivery device into the intracranial subarachnoid space.

A venous access port assembly having a housing base with a discharge port, a septum, and a cap, with an interior reservoir. The housing base is provided with X-ray discernable indicia to identify an attribute of the assembly after its implantation and clearly appear on an X-ray of the patient in a manner informing the radiologist or technologist and the medical practitioner of that particular attribute. Such indicia can be depicted as cutouts through a disc of radiopaque material where the cutouts are in the form of alphabetical letters such as “CT”, or can be a set of discrete elements of radiopaque material, that are affixed along the bottom surface of the housing base or embedded within the thickness of the bottom housing wall.

Methods and systems for determination of flow parameters of administered fluid from a radioembolization delivery device may include translationally moving a device delivery arm of the radioembolization delivery device in a translational direction, wherein the device delivery arm is coupled to a syringe holder such that move in the translational direction one of proximally or distally advances the syringe holder; sensing, via one or more pattern sensors, a corresponding movement of a pattern associated with the translational device delivery arm movement as a sensed pattern movement; generating, via the one or more pattern sensors, one or more output signals based on the sensed pattern movement; and generating, via a processor, a flow rate of the administered fluid, a flow amount of the administered fluid, and/or the translational direction of movement of the device delivery arm with respect to the syringe holder based on the one or more

A position monitoring system is provided that includes a tracheal tube having a distal portion with a radiopaque indicator. The tracheal tube is configured to be positioned within an airway of a patient. The position monitoring system also includes an external sensor configured to be positioned on an external surface of the patient. The external sensor includes an emitter configured to transmit energy into the patient and toward the distal portion and a detector configured to receive a reflected portion of the energy to permit identification of a position of the distal portion. The position monitoring system, in certain embodiments, further includes a video laryngoscope communicatively coupled to the external sensor. The video laryngoscope includes a display and a processor, and the processor is configured to instruct the display to present an indication of the position of the distal portion based on feedback from the detector.

The present invention relates to an implantable heart help device for assisting the pump function of the heart by exerting an external force on the heart. The device is provided with a first fixating member adapted to be fixate the device to a part of the human body comprising bone, a heart pump device having a surface adapted to contact and exert an external force on the heart, a second fixating member in contact with the heart pump device. The second fixating member is displaceable in relation to the first fixating member for changing the position of the surface of the heart pump device, to allow the surface of the heart pump device to contact and exert the external force on at least two different positions on the heart.
