Abstract: This disclosure describes various examples of multi-purpose tools and associated methods for safely gaining access to extravascular spaces. The multi-purpose tools described herein are particularly suited for safely gaining access to the sub-sternal space underneath the sternum/ribcage as well as tunneling subcutaneously above the ribcage for the purpose of positioning of a medical electrical lead. This eliminates the need for separate tools for tunneling in different extravascular spaces by providing a single tool capable of the multiple uses.

Abstract: A medical fixation device which may include an elongate body with a proximal portion, a distal portion, and define a longitudinal axis extending therethrough. A first fixation member on the proximal portion of the elongate body and a second fixation member on the distal portion of the elongate body may also be included with the medical fixation device. The first fixation member and the second fixation member may each have a delivery configuration in which the first fixation member and the second fixation member are collapsed along the longitudinal axis, and an anchoring configuration in which the first fixation member and the second fixation member each extend radially outward from the elongate body, define a septal aperture therebetween, and each have a tip facing away from each other.

Abstract: The medical device may comprise an elongate body having a proximal portion, a distal portion, and defining a lumen therethrough. Also, the medical device may include an expandable element coupled to the distal portion of the elongate body and in fluid communication with the lumen. The expandable element may define a first end and a second end, the second end being proximal to the first end. The medical device may further include a cannula surrounding at least a portion of the elongate body and the cannula may define a proximal end and a distal end. The distal end of the cannula may be disposed proximal and adjacent to the second end of the expandable element. An outer dimctcr diameter of the cannula may be substantially equal to or lesser than an outer diameter of the expandable element when inflated. The medical device may be maneuvered through a patient's body.
