Abstract: Embodiments of the present disclosure relate to an infusion pump system including a holder or carrier for an ambulatory infusion pump that can be worn on or near the patient's body. Embodiments depicted and described herein provide a more versatile and secure way to hold and carry an ambulatory infusion pump.

Abstract: Embodiments of the present disclosure relate to use of a filter in an infusion pump system. The filter can be comprised of a rigid porous plastic material that provides a three-dimensional tortuous path of small pore size that captures particulate as it flows through the filter. Filtration efficiency can be balanced with flow restriction dependent upon pore size of the filter. A range of pore sizes is achievable.

Abstract: A blade for a cutting instrument includes a handle, a body, and at least three cutting edges along the body. The body has first and second sides extending along a longitudinal center axis. The body has a proximal end at the handle and a distal tip remote from the handle. The at least three cutting edges are oriented at corresponding angles with respect to the longitudinal center axis and are asymmetrically distributed with respect to the longitudinal center axis.
