Suture anchor with microthreads and suture anchor drive with needle attachment

A suture anchor is described. The suture anchor includes an elongate anchor body having a proximal end and a distal end, at least one suture secured within the anchor body, at least one major thread, and at least two microthreads occupying the space between each major thread. An anchor driver is also described. The anchor driver is capable of accepting various attachments such that an operator can change the functionality of the driver based on the type of attachment in use, such as a needle attachment. A method of attaching soft tissue to bone in a subject is also described. The method includes the steps of securing a suture anchor into bone with the anchor driver, joining a needle attachment with the anchor driver, passing at least one suture through soft tissue using the needle attachment, and tying the at least one suture against the soft tissue to secure the soft tissue to the bone.

Spinal cord stimulator system

Spinal cord stimulation (SCS) system having a recharging system with self alignment, a system for mapping current fields using a completely wireless system, multiple independent electrode stimulation outsource, and IPG control through software on Smartphone/mobile device and tablet hardware during trial and permanent implants. SCS system can include multiple electrodes, multiple, independently programmable, stimulation channels within an implantable pulse generator (IPG) providing concurrent, but unique stimulation fields. SCS system can include a replenishable power source, rechargeable using transcutaneous power transmissions between antenna coil pairs. An external charger unit, having its own rechargeable battery, can charge the IPG replenishable power source. A real-time clock can provide an auto-run schedule for daily stimulation. A bi-directional telemetry link informs the patient or clinician the status of the system, including the state of charge of the IPG battery. Other processing circuitry in current IPG allows electrode impedance measurements to be made.

An apparatus and method for securing tissue to bone using suture anchors with a pre-loaded piercing structure and sutures

A suture anchor is described. The suture anchor includes an elongate anchor body having a proximal end and a distal end, at least one suture secured within the anchor body, and at least one piercing structure secured within the body extending proximally out of the proximal end of the body, wherein the at least one piercing structure is engaged with the at least one suture. A method of attaching soft tissue to bone in a subject is also described. The method includes the steps of securing an anchor device into a bore formed in the bone, the anchor device comprising an anchor body and at least one pre-loaded piercing structure with at least one suture attached to both the anchor body and the piercing structure, piercing a soft tissue by forcing the at least one piercing structure through the soft tissue, such that at least a portion of the at least one suture passes through the soft tissue, and tying the at least one suture against the soft tissue to secure the soft tissue to the bone.

Methods for attaching tissue to bone utilizing a scaffold

A method for attaching tissue to bone includes the steps of inserting a first anchor into bone, advancing a first limb of a first suture from the first anchor through the tissue and a scaffold, and advancing a second limb of the first suture from the first anchor though the tissue. Alternate methods for attaching tissue to bone are also disclosed.

Labral Anchor System and Method

A suture anchor system includes an anchor having an elongate cylindrical body extending between a proximal end and a distal end, and an eyelet traversing a portion of the elongate cylindrical body, a drill guide having an interior chamber in fluid communication with a distal opening, an elongate anchor inserter having a distal surface configured to interface with a proximal surface of the anchor, and an elongate drill member having a distal drilling tip. The interior chamber is configured to at least partially house the elongate anchor inserter and the elongate drill member.

Methods and apparatus for computer-aided tissue engineering for modeling, design and freeform fabrication of tissue scaffolds, constructs, and devices

One aspect of the invention provides a method for multi-nozzle biopolymer deposition of heterogeneous materials to create or modify a composite biopolymer multi-part three-dimensional assembly having at least one biomimetic and at least one non-biomimetic feature. The method includes: (a) utilizing a CAD environment to design and/or modify a composite multi-part assembly, thereby producing a CAD design; (b) converting the CAD design into a three-dimensional heterogeneous material and multi-part assembly model in a format suitable for three-dimensional, multi-nozzle printing, wherein the design comprises at least one biomimetic feature and at least one non-biomimetic feature; and (c) printing the composite assembly by simultaneously depositing the heterogeneous materials using multiple, different, specialized nozzles, wherein the simultaneous depositing includes direct deposition of cells.

Implantable pulse generator that generates spinal cord stimulation signals for a human body

An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body includes a timing generator and high frequency generator. The timing generator generates timing signals that represent stimulation signals for multiple channels. The high frequency generator determines whether to modulate the timing signals and modulates them at a burst frequency according to stored burst parameters if the decision is yes. As such, the IPG provides the ability to generate both the low frequency and high frequency stimulation signals in different channels according to user programming.
