Suction Fixation Device Tissue Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical fixation devices lack effective mechanisms for retaining support members in place within the body and controlling the depth of penetration during procedures for treating pelvic floor dysfunctions, such as urinary incontinence and prolapse conditions.
Innovation Solution
A medical device featuring a tissue suction housing with adjustable moveable members and suturing device openings, which creates a vacuum to pull up bodily tissue and allows for precise placement and depth control of suturing devices, enabling secure fixation of implants to various tissues within the pelvic region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixation device is used to secure support member to tissue, then the support member is retained in place, but the depth of penetration into tissue cannot be controlled
Solution Approach 1:
The tissue suction housing acts as an intermediary device that captures and holds tissue during the fixation process. The housing creates a controlled environment where the support member can be positioned and secured to tissue with precise depth control, eliminating the uncontrolled penetration issue while maintaining reliable retention.
Solution Approach 2:
The movable member within the tissue suction housing allows dynamic adjustment of the tissue capture depth. By changing the position of the movable member, the system controls the depth parameter at which the support member penetrates the tissue, enabling precise depth control while maintaining secure fixation.
2Manufacturing precision
If a suction fixation device is used to control depth of penetration, then precise placement is achieved, but the device complexity increases
Solution Approach 1:
The tissue suction housing serves multiple functions: it creates suction to capture tissue, positions the tissue at the correct depth, and provides a stable platform for securing the support member. By combining these functions into a single device, the patent achieves precise depth control without proportionally increasing overall device complexity.
Solution Approach 2:
The movable member is nested within the tissue suction housing, allowing compact integration of the depth control mechanism. This nested structure enables precise depth adjustment functionality while minimizing the increase in overall device size and complexity.
3Reliability
If the tissue suction housing is placed under vacuum to pull up tissue, then tissue is securely held for suturing, but additional components are required
Solution Approach 1:
The tissue suction housing combines the vacuum generation capability with the suturing platform into a single integrated device. By merging the tissue capture function and the fixation function into one housing structure, the patent achieves reliable tissue holding without proportionally increasing the number of separate components.

AI summary
In one embodiment, a medical device includes a tissue suction housing and a moveable member disposed in the tissue suction housing. The tissue suction housing has a proximal end and a distal end. The distal end has an opening and the tissue suction housing has at least two suturing device openings. The tissue suction housing is configured to pull up bodily tissue through the opening in the distal end when placed under a vacuum and to receive a suturing device through one of the suturing device openings.
