US Patent:

20230059602, Feb 23, 2023

Filed:

Jul 14, 2022

Appl. No.:

17/864507

Inventors:

- Irvine CA, US
Michael Hoffman - Hillsborough NJ, US

International Classification:

A61F 2/12
A61B 90/00

Abstract:

A prosthetic implant, such as a tissue expander, includes a silicone shell having an anterior wall and a posterior wall, and a needle stop patch secured over an inner surface of the posterior wall of the silicone shell. The needle stop patch has two or more layers of a textile material that are stacked atop one another. The textile material is flexible and includes woven threads or fiber. A bonding material bonds together the two or more layers of the textile material that are stacked atop one another. The outer edges of the respective layers are feathered for minimizing step effects between adjacent ones of the layers. A self-sealing membrane covers the anterior wall of the silicone shell. The dernier level of the textile layers increases between top and bottom layers for progressively increasing resistance tom a needle passing through the needle stop patch.

International Classification:

A61B 17/06

Abstract:

A wound closure assembly includes an insertion tool having a proximal end and a distal section, such as a curved distal section, having a penetrating tip and first and second notches that are formed on opposite sides of the distal section. The assembly includes a tissue anchor having a hollow body and an insertion tool channel extending through the hollow body. First and second spaced tips project distally from the distal end of the hollow body and oppose one another on opposite sides of the insertion tool channel. The distal section of the insertion tool is inserted into the insertion tool channel of the tissue anchor so that the penetrating tip is distal to the first and second spaced tips, with the first and second spaced tips nested within the first and second notches for generating a releasable interference fit between the tissue anchor and the insertion tool.

International Classification:

A61F 2/12
A61B 90/00
F04B 43/02

Abstract:

The present disclosure describes various embodiments of adjustable implants, particularly permanent breast implants, intended for implantation into a subject, particularly a human subject. In some embodiments, the adjustable implant comprises a shell including a resilient shell membrane, a first reservoir containing a fluid, e.g., a saline, a second reservoir including a resilient second-reservoir membrane, and a pump. The pump may include a first pump actuator, a first pump inlet, and a first pump outlet. The first reservoir and second reservoir may be disposed within the shell and be in fluid communication via the pump. Fluid may be transferred between the two reservoirs to change the profile of the implant.
