Modular Catheter Systems in Minimally Invasive Interventional Medical Procedures: A Case Study
ABSTRACT
Background:
The medical device catheters that are used in minimally invasive interventional medical procedures all follow the same integrated design and use paradigm. The features and elements of any catheter device are combined in a single unitary construction. The work presents a proposed modular construction approach as a new paradigm offering significant advantages and benefits over the existing integrated design paradigm.
Objective:
The objective of this paper is to present the results and finding of a modular balloon catheter system design and initial veterinary use as a case study for the potential of Modular Catheter Systems in general. The proposed Modular Catheter System can be a means for physicians to create interventional catheter devices at the time of a procedure to meet specific procedural needs.
Methods:
A Modular Catheter System was designed using commercially available balloon dilation catheters as one module (Parent Module) in the system and a custom designed Scoring Adapter (Adapter Module) as the other module. The Scoring Adapter incorporates scoring wires to add scoring features to the Parent Module (balloon catheter) during a pulmonary valvuloplasty procedure. The Adapter Module also includes a novel Attachment Mechanism to couple the Scoring Adapter (Adapter Module) to any .035” guidewire compatible balloon dilation catheter (Parent Module).
Results:
The Scoring Adapter with Attachment Mechanism was successfully designed, manufactured and used in a minimally invasive veterinary cardiovascular intervention to treat a case of canine subvalvar pulmonary stenosis.
Conclusions:
The successful design and use of the presented Modular Catheter System demonstrates the feasibility and potential advantages of this type of system paradigm to enable physicians to create interventional catheter devices at the time of a procedure guided by the procedural needs. The Modular Catheter System can be used to create catheter devices analogous to an integrated catheter device that are not otherwise available.
