Multi-Implant Delivery Handle for In-Place Prostate Compression

Solution Overview

Problem

Current treatments for Benign Prostatic Hyperplasia (BPH) are only partially effective and burdened with significant side effects, and there is a need for new devices and methods to alleviate pressure on the urethra by compressing at least a portion of the prostate gland, thereby alleviating pressure on the urethra.

Innovation Solution

Deployment of one or more anchor assemblies or implants into the prostatic tissue, anchored simultaneously to the outer prostatic capsule and urethral side of the prostate, compressing the tissue to relieve urethral constriction, using a delivery device that can be reloaded 'on the fly' and deploy multiple implants without removing the elongate shaft from the patient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple implant assemblies are deployed using separate delivery devices or cartridges, then each implant can be delivered to targeted tissue, but the procedure requires multiple cartridge exchanges and removals/reinsertions of the shaft assembly, increasing procedure time and complexity

Engineering Contradiction:

Improvenumber of implants deployedVSAvoidprocedure time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent combines multiple implant assemblies into a single delivery device, allowing multiple implants to be deployed without removing the shaft assembly. The delivery device includes a handle assembly with spooling mechanisms that can sequentially deploy multiple implant assemblies through the same shaft, eliminating the need for multiple cartridge exchanges and reducing procedure time.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The delivery device is designed as a multi-functional system that can deliver multiple different implant assemblies through a single shaft assembly. The handle assembly incorporates multiple spool members that can independently control different implant assemblies, allowing the same delivery device to perform multiple implantation functions without requiring separate devices for each implant.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If multiple implant assemblies are deployed using separate delivery devices or cartridges, then each implant can be delivered to targeted tissue, but the device complexity increases due to multiple cartridge exchanges and associated removals/reinsertions

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple implant assemblies into a single delivery device, allowing multiple implants to be deployed without removing the shaft assembly. The delivery device includes a handle assembly with spooling mechanisms that can sequentially deploy multiple implant assemblies through the same shaft, eliminating the need for multiple cartridge exchanges and reducing procedure time.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The delivery device incorporates self-contained spooling mechanisms within the handle assembly that automatically manage the deployment of multiple implant assemblies. The spool members can be independently actuated to deploy each implant in sequence without requiring external intervention or removal of the shaft assembly, simplifying the overall delivery procedure.

Inventive Principle:

Principle #25Self-service

AI summary

Implant delivery systems are configured to deploy multiple implants into targeted tissue within a patient without disengaging a delivery component of the systems from its insertion site in the patient. Various combinations of spooling assemblies, spring-loaded features, manifolds, indexing mechanisms, gearings, and manually engageable actuators operate to deploy the implants in a controlled, serial fashion. Implants or portions thereof are pre-loaded into the handle assemblies of the delivery systems or contained in removable cartridges configured for coupling to the handle assemblies.
