An inhalation spacer movable between a collapsed configuration and an expanded configuration. The spacer is made from paperboard having a bending stiffness of at least 2.5 mNm.

Systems and methods include a heat transfer body with opposing major surfaces formed from a thermally conductive substrate in intimate thermal interaction with an alumina exterior surface that extends across the major surfaces of the body. In an illustrative example, the heat source may be a substantially planar, silicone-based heater source (P-SBHS). The heat transfer body may be configured to thermally interact, for example, heat from a heat source proximate a first of the major surfaces to a second of the major surfaces. A temperature sensor module may be located, for example, proximate to the first major surface such that a temperature sensor thermally interacts with the first major surface. The temperature sensor module may, for example, insulate the temperature sensor from the P-SBHS.

The invention involves a system and method for straightening and refurbishing medical catheters. The system includes the steps and equipment to repair bends and kinks which prevent proper usage of the catheter for a medical procedure. The system and method further checks electrical conductivity and resistance if needed. The catheters are then cleaned and repackaged for shipment and use.

Disclosed are various examples and embodiments of a cardiac mapping catheter configured for electrophysiological (EP) mapping and suitable for intravascular insertion in a patient's heart, and methods of making same. The cardiac mapping catheter comprises a plurality support arms having electrodes disposed thereon. Various configurations of the cardiac mapping catheter are described and disclosed which provide improved spatial resolution and sensing of EP signals acquired from inside a patient's heart.

This disclosure relates to a medical device including a hard part and a converter. The hard part has fluid paths for conducting a medical fluid through the hard part. The converter is arranged to measure a characteristic of the medical fluid while the medical fluid is present in one of the fluid paths. At least a section of the converter is applied or superimposed to the hard part by at least one additive application method.

A covered catheter, including a catheter body coated with a lubricant to facilitate entry into tissue of a user, and a covering sheath, including a sheath body to cover at least a portion of the catheter body in an extended position, and expose the catheter body in a retracted position, a first end cap disposed on at least a portion of a first end of the sheath body to enclose the first end of the sheath body, and a second end cap disposed on at least a portion of a second end of the sheath body to enclose the second end of the sheath body.

The disclosure teaches the use of antistatic materials in the airway for thermal aerosol generation devices. The present disclosure teaches the use of antistatic materials for drug delivery in any drug that may be susceptible to charging during aerosol generation.

Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a housing, negative pressure source, circuit board, and one or more controllers. The circuit board can be supported by the housing and include a conductive pathway extending around at least part of a perimeter of a first side of the circuit board. The conductive pathway can be electrically coupled to an electrical ground for the circuit board. The one or more controllers can be mounted on the circuit board and activate and deactivate the negative pressure source.

A system and method for calibrating an IV pump infusion system tube comprises a fluid source, an infusion system comprising, an IV pump, a drive unit, a chamber with known constant volume, a control unit, and IV tubing with a known inner diameter tolerance, and a switch and magnetic floating object. The system administers medicinal fluid, calculates the flow rate of the medicinal fluid in the chamber by measuring the time the switch is activated as medicinal fluid rises in the chamber, compares the calculated flow rate with a set flow rate of the IV pump input in the control unit prior to infusion, and adjusts the IV pump and flow rate based on the compared deviations for more accurate delivery to a patient. This configuration may provide a more precise delivery rate of medicinal fluid, preventing harm to the patient and waste of medicine.

An intravascular blood pump having a rotatable shaft carrying an impeller and a housing with an opening through which the shaft extends with the impeller positioned outside the housing. The shaft and the housing have surfaces forming a circumferential gap which converges towards the impeller-side end of the gap and which has a minimum gap width of preferably no more than 5 μm, more preferably no more than 2 μm.
