Single Needle Kit for Simultaneous Therapy Element Implantation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for implanting percutaneous therapy elements, such as leads and catheters, often require multiple needlesticks, which can be invasive and increase the risk of trauma and damage to the therapy elements, especially when positioning multiple elements at distinct locations within a patient.
Innovation Solution
A kit and method utilizing a single paddle-shaped needle with a lumen capable of receiving two or more therapy elements simultaneously, allowing independent positioning of separate electrical leads and catheters at distinct locations within the patient, reducing the need for multiple needlesticks and minimizing trauma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate needles are used to implant multiple therapy elements, then each therapy element can be positioned at distinct locations, but the invasiveness increases and the risk of trauma and damage to therapy elements increases
Solution Approach 1:
The patent combines multiple needles into a single integrated needle assembly with multiple lumens, allowing multiple therapy elements to be implanted simultaneously through one puncture site. This merging approach reduces the number of skin punctures from multiple to one, thereby reducing trauma and improving reliability while maintaining the ability to position elements at distinct locations through independent lumen routing.
Solution Approach 2:
The needle assembly is designed as a multi-functional device that can simultaneously accommodate and deliver multiple different therapy elements (e.g., leads, catheters) through a single structure. Each lumen within the needle can receive different types of therapy elements, allowing the single needle to perform the function of multiple separate needles while reducing procedural invasiveness.
2Manufacturing precision
If multiple needlesticks are performed to implant multiple therapy elements, then precise positioning at distinct locations is achieved, but the procedure becomes more invasive and time-consuming
Solution Approach 1:
By merging multiple needle functions into a single needle assembly with multiple lumens, the patent enables simultaneous implantation of multiple therapy elements in one procedural step. This eliminates the sequential time required for multiple separate needle insertions and positioning operations, significantly reducing total procedure time while maintaining precise positioning capability through independent lumen control.
Solution Approach 2:
The needle assembly is pre-configured with multiple lumens positioned and oriented to access distinct target locations. This preliminary arrangement of the needle structure allows all therapy elements to be routed to their respective destinations simultaneously during a single insertion, eliminating the need for repeated positioning operations and reducing overall procedure time.
3Adaptability or versatility
If multiple separate needles are used, then independent positioning of therapy elements is possible, but the complexity of the implantation procedure increases
Solution Approach 1:
The patent merges multiple needle functions into a single integrated assembly where each lumen can independently receive and deliver different therapy elements to distinct locations. This unified structure simplifies the implantation procedure by reducing the number of separate devices the operator must manage, while maintaining independent positioning capability through the independent routing provided by each lumen.
Solution Approach 2:
The multi-lumen needle assembly serves as a universal platform that can accommodate various types of therapy elements (leads, catheters, etc.) simultaneously. Each lumen functions independently to deliver its assigned therapy element to the appropriate location, providing versatility in element selection and positioning while presenting a single, manageable device to the operator, thereby reducing procedural complexity.

AI summary
This disclosure describes a kit to facilitate implantation of therapy elements into a patient, and techniques for percutaneously inserting therapy elements into a patient. In particular, embodiments of the invention are directed to techniques for percutaneously inserting two or more therapy elements into a patient via a single needle. In one embodiment, the invention is directed to a kit to facilitate implantation of therapy elements into a patient. The kit comprises a needle defining a lumen a first therapy element sized to pass through the lumen, and a second therapy element sized to pass through the lumen. The lumen is sized to receive both of the first and second therapy elements simultaneously. The first and second therapy elements are separate and not attached to one another such that distal ends of the first and second therapy elements can be positioned to provide therapy in distinct locations of the patient.
