Embodiments include a method comprising determining histological factors at a target site of a subject, and determining parameters of a fractional resection based on the histological factors. The parameters include dimensionality of a fractional field, orientation of the fractional field, resection depth, and a vector of directed closure. The method includes configuring a cannula assembly for the fractional resection that includes a procedure to generate a fractional field at the target site by fractionally resecting tissue according to the parameters. The fractional resection includes applying a cannula array of the cannula assembly to the target site, and rotating at least one cannula of the cannula array to circumferentially incise and remove a plurality of skin plugs in the fractional field.

A tissue expander having a shell, an opening in the shell in communication with an external vacuum source to apply a vacuum within the shell and impart a distracting force to expand tissue, and a rim connected to the shell and adapted to be in contact with a skin of a patient. The rim is non-fixedly attached to the skin of the patient and moves laterally outwardly with respect to the shell under application of the vacuum.

A tissue expander is disclosed herein. The tissue expander may comprise a shell defining a chamber, and having a flexible wall and a port disposed through the flexible wall. The shell may also include a channel disposed through the flexible wall. A first syringe containing a first volume of a liquid may be connected to the chamber of the tissue expander via the channel. A second syringe containing a second volume of the liquid may be connected to the chamber via the port at least approximately one week after the first volume of liquid is injected. The first volume of liquid may be injected more quickly than the second volume of liquid.

Surgical tools and kits for performing methods include a grommet with cylindrical shaft, cutting tip, annular flange with suture retaining anchoring fixture; a grommet jig for extending between adjacent grommets and guiding a needle therebetween; a family of needles with single and double pointed ends, reinforced eyelets, stops to limit inadvertent exiting, double shaft construction with a longitudinal gap and sharpened, slicing ends, including a “J” shape embodiment; a bone anchor with ring to secure sutures about a patient's clavicle; a tissue dissector having radially extending cones to nick taut connecting tissues; a tissue rasp having a series of crisscrossing grooves along an end; a tissue mesher comprising one or more blocks having a matrix of holes for clamping a plurality of needles and a supporting framework; and a kit device and a method of surgically inserting an internal mesh brassiere under the breast skin.

Aspects of the present disclosure are directed to a medical implant introducer (100) and methods of its use. The introducer (100) may include a handle (120), an implant-holding cavity disposed distally from the handle (120), a fluid supply conduit (122) fluidly coupled to an interior portion of the implant-holding cavity, and a distal nozzle (110) having a proximal portion, a distal portion, a middle portion in between the proximal portion and the distal portion, the middle portion having a tapered profile such that the proximal portion is larger than the distal portion, and a distal opening (112), wherein an implant in the implant-holding cavity may be expelled from the introducer (100) through the distal opening (112).

This application concerns a retractor device for breast reconstruction surgery. Specifically, the present patent application relates to a retractor type medical device which entails the effective exposure and visibility of the breast pocket and, at the same time, does not compromise the integrity of the subcutaneous flap, resulting in a positive outcome of the breast reconstruction procedure generally, but not exclusively, performed using a prepectoral (or sub-cutaneous) acellular biological matrix.

An implant-delivery sleeve may comprise an enclosure having at least one opening and at least one vent conduit. The vent conduit may extend along a surface of the enclosure to assist in removing fluids (e.g., blood and air) from the tissue pocket to facilitate implantation of the implant.

A tissue expander is disclosed herein. The tissue expander may comprise a shell defining a chamber, and having a flexible wall and a port disposed through the flexible wall. The shell may also include a channel disposed through the flexible wall. A first syringe containing a first volume of a liquid may be connected to the chamber of the tissue expander via the channel. A second syringe containing a second volume of the liquid may be connected to the chamber via the port at least approximately one week after the first volume of liquid is injected. The first volume of liquid may be injected more quickly than the second volume of liquid.

The present disclosure includes customized guidance devices in the form of guidance templates configured to fit over a given area of a patient's body and provide guidance during a tissue treatment or tissue removal procedure of that given area, which may include administration of an agent to a target tissue, target tissue biopsy, target tissue resection, or target tissue ablation. The customized guidance templates are generally constructed via an additive manufacturing process (i.e., three-dimensional (3D) printing) or subtractive manufacturing process (i.e., milling) based on a fabrication instruction file, which may include imaging data of the given area of the patient's body in which targeted tissue treatment is to be performed. The fabrication instruction file may further include additional data, such as the type of procedure to be performed (i.e., biopsy of the tissue abnormality, destruction or resection of the tissue abnormality, etc.).
