SYSTEMS AND METHODS FOR PROVIDING A CONVECTION-ENHANCED DELIVERY DEVICE
First Claim
1. A catheter mounting apparatus, comprising:
- a base having a substantially planar surface for forming an interface with a patient;
a receiving channel forming a distal end of the base and configured to receive an adapter portion of a catheter, a portion of the receiving channel further having a clip catch;
a catheter support having a first cambered surface and a first groove for receiving a tube portion of the catheter;
an aperture positioned proximal to the catheter support, the aperture providing a pathway through the base to accommodate passage of the tube portion of the catheter through the base;
a clip hingedly coupled to a proximal end of the base, the clip having an inner surface and an outer surface, the inner surface having a second cambered surface and a second groove for retaining the portion of the catheter against the first cambered surface and the first groove, the outer surface having a ledge feature to compatibly interlock with the clip catch, wherein the clip comprises an opened position and a closed position.

Abstract
A delivery device system is provided for assisting a patient and physician in maintaining a depth and position of an inserted catheter within a target tissue. The delivery device includes a base member that is secured to an external surface of the patient. The base member includes an aperture through which a catheter is inserted to access the target tissue. The base member further includes a hinged clip that selectively locks into a closed position to secure the catheter within the delivery device and maintain a desired insertion depth of the catheter within the target tissue. The base member further includes a receiving channel for compatibly and adjustably securing an adapter portion of the catheter in a horizontal orientation.

9. A method for adjustably securing a catheter to a patient in a low profile configuration, the method comprising:
-
accessing a target tissue of the patient by providing an access aperture through a bone of the patient; securing a catheter retaining device to an external surface of the patient via a plurality of fasteners, an aperture of the catheter retaining device being aligned with the access aperture of the patient; inserting a tip portion of the catheter into the target tissue via the access aperture and the aperture of the catheter retaining device; advancing the tip portion of the catheter to a desired depth within the target tissue; securing an adapter portion of the catheter into a receiving channel of the catheter retaining device, the receiving channel being generally perpendicular to a vertical plane of the access aperture and the inserted portion of the catheter; supporting an uninserted portion of the catheter with a catheter support having a first cambered support surface; securing the uninserted portion of the catheter between a hingedly coupled clip and the catheter support, the hingedly coupled clip including a second cambered support surface and further including a tab feature configured to interlock with a clip catch portion of the receiving channel in a closed position, wherein the adapter portion of the catheter interlocks within the receiving channel to maintain the desired depth of the tip portion of the catheter. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A low profile catheter mounting device, comprising:
-
a base having a substantially planar surface for forming an interface with a patient; a receiving channel forming a distal end of the base and having a horizontally positioned cavity for receiving an adapter portion of a catheter, a portion of the receiving channel further having a clip catch; a catheter support having a first cambered surface for supporting an uninserted portion of the catheter in an arched configuration; an aperture positioned proximal to the catheter support, the aperture providing a pathway through the base to accommodate passage of a tip portion of the catheter through the base; a clip hingedly coupled to a proximal end of the base, the clip having an inner surface and an outer surface, the inner surface having a second cambered surface for retaining the uninserted portion of the catheter against the first cambered surface of the catheter support, the outer surface having a ledge feature to compatibly interlock with the clip catch, wherein the clip comprises an opened position and a closed position. - View Dependent Claims (18, 19, 20, 21, 22)
