An externally programmable shunt valve assembly that includes a motor having a rotor that is operable in response to an externally applied magnetic field and configured to increase or decrease the working pressure of the shunt valve assembly. The motor may further include a position sensing mechanism that allows a position of the rotor, and associated pressure setting of the valve, to be determined using an external magnetic sensor. In certain examples the motor further includes a mechanical brake that is magnetically operable between a locked position and an unlocked position and which, in the locked position, prevents rotation of the rotor.

A method of fixating an implantable heart help device in a human patient is provided. The method comprises the steps of: cutting the skin of said human patient, dissecting an area of the body comprising bone, and fixating said implantable heart help device to said part of the body comprising bone.

A power-injectable access port and methods of making are described. One method of making includes forming a power-injectable access port housing, creating a screen including one or more apertures through the screen in the shape of one or more alphanumeric characters, suspending a radiopaque material in a silicone material to form a radiopaque suspension, and depositing the radiopaque suspension onto a surface of the power-injectable access port housing through the one or more apertures of the screen to create at least one radiopaque identification feature. The at least one radiopaque identification feature may have a thickness protruding from an outer surface of the port base such that it is perceivable by sight and touch prior to implantation of the power injectable access port, and is observable via imaging technology subsequent to subcutaneous implantation of the power-injectable access port.

Systems and methods for implanting an endovascular shunt in a patient is disclosed. The system having an expandable anchor configured for being deployed in a dural venous sinus of a patient at a location distal to a curved portion of a wall of an inferior petrosal sinus (IPS) of the patient; an elongate guide member coupled to, and extending proximally from, the anchor; a shunt delivery catheter having a first lumen configured to receive the guide member, and a second lumen extending between respective proximal and distal openings in the shunt delivery catheter, the shunt delivery catheter further having a penetrating element coupled to a distal end of the catheter; and the system further having a guard at least partially disposed over, and movable relative to, the penetrating element.

A dry powder medicament inhaler for metering an inhalation of dry powdered medicament may include at least one inlet and at least one outlet, wherein a communication between said inlet and outlet at least includes a mixing and deaggregation chamber and at least two dosage communications between the inlet and the chamber. The inhaler may also include a dosage mechanism for arranging at least one dose of a medicament between the inlet and the chamber, such that said at least one dose may be delivered upon inhalation at said outlet through said communications. The inhaler may further include a locking mechanism, wherein on moving the dosage mechanism from a dose collecting position to a dose administering position the locking mechanism may be moved from an unlocked to a locked position preventing the metering of any further doses prior to resetting of the locking mechanism. Instead of a locking mechanism, the inhaler may include a dosage indicator or a counterweight mechanism. The inhaler may also include combinations of a locking mechanism, a dosage indicator, and a counterweight mechanism.

An implantable device for improving the pump function of the heart of a human patient by applying an external force on the heart muscle. The device comprises at least one pump device comprising a heart contacting organ, an operating device for operating the heart contacting organ, and an implantable pressurized fluid system. The fluid system comprises a first implantable chamber adapted to hold a pressurized fluid, wherein said first chamber is adapted to hold a fluid having a high pressure and a second implantable chamber adapted to hold a pressurized fluid, wherein said second chamber is adapted to hold a fluid having a lower pressure. The movement of the heart contacting organ assists the pump function of the heart.

A urinary catheter may include a catheter shaft and a connector coupled with the proximal end of the catheter shaft. The connector may have a first arm ending in a fluid outlet configured to allow urine to flow out of the urinary catheter and a second arm with an aperture and ending in an inflation inlet used for introducing inflation fluid into the urinary catheter. The catheter may further include a primary lumen, an inflation lumen, a retention balloon mounted to the catheter shaft proximal to a fluid inlet and over a distal filling hole, and a pilot balloon mounted on the second arm of the connector over the aperture. The pilot balloon inflates at an inflation pressure that is higher than the inflation pressure of the retention balloon and lower than a predetermined pressure threshold.

A drainage catheter configured for draining bodily fluid from a patient is disclosed. The drainage catheter may comprise a catheter tube with a drainage lumen and a suture lumen. A suture of the drainage catheter may be disposed within the suture lumen. The suture may be coupled to a distal end of the catheter tube and extend proximally through a hub disposed at the proximal end of the catheter tube.

Apparatus for identifying a patient, said apparatus comprising: a medical device for implantation into the patient; an optical identifier affixed to the medical device; wherein at least a portion of the optical identifier is radiopaque, whereby to generate a scannable X-ray image of the optical identifier when the medical device is imaged using X-ray.
