  • Publication number: 20240115292
    Abstract: Exemplary embodiments of apparatus and method for obtaining one or more portions of biological tissue (“micrografts”) to form grafts are provided. For example, a hollow tube can be inserted into tissue at a donor site, and a pin provided within the tube can facilitate controlled removal of the micrograft from the tube. Micrografts can be harvested and directly implanted into an overlying biocompatible matrix through coordinated motion of the tube and pin. A needle can be provided around the tube to facilitate a direct implantation of a micrograft into a remote recipient site or matrix. The exemplary apparatus can include a plurality of such tubes and pins for simultaneous harvesting and/or implanting of a plurality of micrografts. The harvested micrografts can have a small dimension, e.g., less than about 1 mm, which can promote healing of the donor site and/or viability of the harvested tissue.

  • Publication number: 20240094741
    Abstract: Disclosed herein are a method and apparatus for automated following behind a lead vehicle. The lead vehicle navigates a path from a starting point to a destination. The lead vehicle and the following vehicle are connected via V2V communication, allowing one or more following vehicles to detect the path taken by the lead vehicle. A computerized control system on the following vehicle (a Follow-the-Leader, or FTL, system) allows the following vehicle to mimic the behavior of the lead vehicle, with the FTL system controlling steering to guide the following vehicle along the path previously navigated by the lead vehicle. In some embodiments, the lead vehicle and following vehicle may both use Global Navigation Satellite System (GNSS) position coordinates. In some embodiments, the following vehicle may also have a system of sensors to maintain a gap between the following and lead vehicles.

  • Publication number: 20220176153
    Abstract: An osseointegrated fixture of a percutaneous osseointegrated prosthesis (POPs) anchors directly into a bone of a residual limb within an amputation stump. By anchoring directly into the bone, the POPs provides improved mobility, comfort, and function for an amputee, but an interface between an opening in the skin and the osseointegrated fixture, which allows the anchoring directly into the bone, is prone to infection by microbes. An anti-microbial device can be attached to and/or embedded within an extracorporeal portion of the osseointegrated fixture to irradiate at least a portion on the interface with at least one wavelength of light selected for its antimicrobial effects.

  • Publication number: 20210145476
    Abstract: Systems and methods are provided for performing a hair transplant using a hair transplant device. The hair transplant device comprises a coring needle, a splitting needle, a housing, and a user interface. The coring needle forms a coring lumen configured to extract a hair follicle from a donor site. The splitting needle is configured to create an opening in a recipient site. The housing at least partially surrounds one of the coring needle and the splitting needle. The user interface extends from the housing and is movable relative to the coring needle to push the hair follicle from the coring lumen into the opening in the recipient site formed by the splitting needle.

  • Publication number: 20210030457
    Abstract: In one aspect, the present invention provides a method of cooling to produce selective disruption of visceral fat tissue in a non-infant human subject comprising infusing a cooled fluid into the abdominal or peritoneal cavity, or into other parts of the body containing visceral fat, to cool the proximal tissue sufficiently to selectively disrupt lipid-rich cells therein, for example, to promote subsequent damage and absorption of lipid-rich cells by the body without producing unwanted effects in non-lipid-rich cells; e.g., without injury to internal organ tissues that could otherwise produce life-threating risks. The cooled fluid can be infused using a catheter arrangement. The cooled fluid can be retained within the abdominal category for a particular duration, and then drained using the catheter arrangement. In certain embodiments, the cooled fluid can be simultaneously introduced into the abdominal cavity and drained therefrom.

  • Publication number: 20190350610
    Abstract: A tissue harvesting and wound closing device includes first and second actuator strip guides of a strip that are slideable along first and second panel guides of a panel, respectively. A first section of a base of the actuator strip has a substantially uniform width between the first and the second actuator strip guides. A second section of the base has a gradually decreasing width between the first and second actuator strip guides. A third second section of the base has a substantially uniform width between the first and second actuator strip guides that is smaller than the first width. When the actuator strip is pulled, the first and second actuator guides slide along the first and second panel guides, respectively, to cut a strip of tissue strip creating an open wound, and a panel pulls proximal tissue on opposite sides of the open wound to close the wound.
