A sterile environment system can include an enclosure and a support system. The enclosure can include a barrier separating a sterile environment inside of the enclosure from a non-sterile environment outside of the enclosure. The barrier can include an expandable portion configured to expand from an unexpanded state to an expanded state for working within the sterile environment, and a patient-interfacing portion including a fenestration configured for placement directly over an area of interest of a patient, the fenestration having a sealed state and an unsealed state for access to the area of interest from within the sterile environment. The support system can be coupled to the patient-interfacing portion of the barrier such that it is positioned on at least opposite sides of the fenestration.

Enclosures including systems and methods thereof for establishing a sterile environment for a medical procedure

A stylet for use in guiding a catheter to a predetermined location within the body of a patient includes a continuous core member for transmitting an electrical signal from a distal section of the stylet to a proximal end. The stylet includes a differing stiffness profile along its length. The differing stiffness characteristics are achieved by varying the number of strands of a wire, the diameter of each individual strand, twisting or braiding the strands, or varying the number of turns per unit length of the twisted strands. The stiffness of the stylet may decrease intermittently or continuously from the proximal end to the distal section. By using multiple strands bundled together, the beneficial conductive and, optionally, magnetic properties can be maximized while at the same time the stiffness characteristics can be modified.

Apparatus and methods to modulate stylet stiffness profile

Disclosed are enclosures for establishing a sterile environment over a patient for a medical procedure, as well as systems and methods thereof. An enclosure can include an expandable portion of a barrier separating a sterile environment inside of the enclosure from a non-sterile environment outside of the enclosure and a patient-interfacing portion of the barrier. The enclosure can also include a support system coupled to the patient-interfacing portion of the barrier in some embodiments. The patient-interfacing portion of the barrier can include one or more fenestrations for placement directly over one or more areas of interest of the patient, as well as for access to the areas of interest from within the sterile environment. When present, the support system can flank the fenestration. The support system is configured to support the enclosure on a surface when placed over an appendage of the patient or a main body of the patient.

Disclosed herein are wound-healing systems and methods thereof. A wound-healing system can include a wound dressing, a catheter-stabilization device, and an electrical-stimulation means for applying electrical stimulation to heal or protect at least a wound associated with a percutaneous insertion site of a patient. The wound dressing can be configured as an electrode for placement around the wound. The catheter-stabilization device can include an anchor pad and a retainer coupled to the anchor pad. The anchor pad can be configured to adhere to skin of the patient proximate the insertion site. The retainer can be configured to stabilize a catheter assembly while a catheter tube of the catheter assembly is disposed in the insertion site. The electrical-stimulation means can include an electrical power source and an external circuit between the catheter-stabilization device and the wound dressing for applying the electrical stimulation.
