Embodiment Construction

[0036] refer to Figure 1A and 1B , depicts a medical device 100 configured to improve medicament dispersion in accordance with an embodiment of the disclosure. The medical device 100 can include an implantable catheter 102 which, in some embodiments, can be connected to an implantable port 104 (such as Figure 1A -B depicted) or implantable pump 106 (as Figure 7 Depicted) fluid communication. As depicted, medical device 100 may be implanted within body B of a patient. In some embodiments, the distal tip 108 of the implantable catheter 102 may optionally be surgically implanted into a ventricle V in the patient's brain (eg, Figure 1A depicted) or the patient's intraspinal space (eg Figure 1B depicted). Implantable port 104 or implantable pump 106 can be placed cranially (e.g. Figure 1A as depicted in ), or placed inside the dry cavity or close to the patient's ribs (eg Figure 1B depicted in ). In either case, the implanted port 104 or implanted pump 106 is typically ...

Abstract

A medical device configured to improve dispersion of a medicament within cerebrospinal fluid of a patient is disclosed. The medical device includes an implantable catheter having: a distal tip configured to be positioned within a cerebrospinal fluid flow; a proximal tip; a body defining a lumen extending longitudinally along the implantable catheter, the lumen configured to enable a medicament to flow from the proximal tip to an infusion port positioned proximate the distal tip; and a piezoelectric element positioned proximate the infusion port, the piezoelectric element configured to selectively oscillate during administration of a medicament to improve dispersion of the medicament within the cerebrospinal fluid.

Description

technical field [0001] The present technology relates generally to implantable medical devices, and more particularly to systems and methods utilizing implantable catheters with piezoelectric tips for increasing drug dispersion into a patient's cerebrospinal fluid. Background technique [0002] Implantable medical devices, such as implanted access ports or medical pumps, suitable for the prescription of therapeutic agents, nutrients, drugs, pharmaceuticals such as antibiotics, blood coagulants, analgesics and other fluids and / or fluid-like substances (collectively referred to as " Drugs" or "infusions") are delivered and dispensed to patients in volume and time-controlled doses. Such implantable devices are particularly useful in the treatment of diseases and conditions requiring periodic or chronic (i.e., long-term) pharmacological intervention, including tremor, spasticity, multiple sclerosis, Alzheimer's disease, Parkinson's disease disease, amyotrophic lateral sclerosis...
