Abstract
Embodiments relate to subcutaneous insertion systems comprising a surface device to be applied to a patient's skin and an insertion system for applying the surface device to the patient, wherein the applying can include subcutaneous insertion of a cannula or other element, and related devices and methods. The surface device comprises a surface for application to the skin of a patient and a subcutaneous element, such as a cannula, wire, filament or other device, extending from the skin's surface at an angle greater than 0 degrees and less than 90 degrees.
Claims20
An insertion site, comprising:
- a patient-side surface;
- a central hub having a side aperture formed therein;
- a subcutaneous element coupled to the site at an acute angle with respect to the patient-side surface;
- and
- a septum having a longitudinal axis that is coaxial with a longitudinal septum axis of the central hub extending substantially orthogonally from the patient side surface,
- wherein the side aperture of the central hub configured to enable an insertion needle to pass through the septum at an oblique angle relative to the longitudinal septum axis, to enter the subcutaneous element at the oblique angle.
A method of deploying a subcutaneous element at an acute angle relative to a surface of a skin of a patient to improve a likelihood of landing the subcutaneous element in a subcutaneous layer of the patient, the method comprising:
- providing a insertion site to be applied to a skin of a patient, the site comprising a patient-side surface, a central hub having a side aperture formed therein, a subcutaneous element coupled to the site at an acute angle with respect to the patient-side surface, and a septum having a longitudinal axis that is coaxial with a longitudinal septum axis of the central hub extending substantially orthogonally from the patient side surface,
- passing an insertion needle through the septum at an oblique angle relative to the longitudinal septum axis, to enter the subcutaneous element at the oblique angle.
