A method, system and apparatus for augmenting the surgical repair of soft tissue injuries, in which a first end of a bridge member attaches to a first portion of healthy tissue, and a second end of the bridge member attaches to a second portion of healthy tissue. The bridge member (or bridge members) used to augment the soft tissue repair may be interconnected or function independently. Flexibility and elasticity of the bridge member are determined by the situation and may be altered to improve healing. The device may be used in arthroscopic procedures, and may be manufactured in a variety of lengths, or may be manufactured one length and be cut to the desired length, or otherwise altered to provide an optimal length of the bridge member.

An implant for repairing soft tissue injuries is provided comprising at least one channel for receiving a soft tissue graft such as a tendon, ligament, or other soft tissue, to be implanted in a patient.

The implant can be biodegradable, and the implant-graft assembly has a pull-out strength sufficient to withstand everyday use during patient recovery.

A cutting tool to be utilized in the resection or removal of bone tissue from patients includes a handle that tensions a wire or cable-like cutting member with a small diameter between at least two features on the handle to present a thin cutting profile. The design of the cutting tool includes features that protect against soft tissue damage and minimize the incision size necessary to utilize the tool. Some embodiments feature details of the cutting tool that interface with a surgical cutting guide system. Other embodiments describe a cutting tool with a selectively changeable length of the cutting profile of the wire cutting member. In one embodiment, the wire cutting member of the cutting tool is energized by mechanical energy in the form of a unidirectional rotation of the cutting member, a mechanical vibration of the cutting member, or an oscillating movement of the wire cutting member.

A method and soft tissue cleat device for improving the repair of soft tissue damage. A disc having projections pierces soft tissue and securely joins with a second disc to coapt the interposed soft tissue. This provides an increased pull-out strength of the suture and resistance to shear stresses, improving the quality of the repair. The present invention may be used with any bone fixation devices to reattach soft tissue to bone, and may also be used to rejoin soft tissues after a tear in the tissue.

A re-usable bandaging system for treating acute soft-tissue injuries and the like provides protection, support and restraint, and optional heating or cooling and uses straps enabling the system to be placed at one of many sites. A flexible, resilient insulating material, covered with loop-bearing fabric comprises (A) a main bandage that is a rectangular panel with a pocket and (B) two straps at diagonally opposite corners. Each strap has an area of complementary hooks at the free end, to adhere to the bandage when in use. A supplementary bandage (C) is for optional use as a strap when stabilising the main bandage. The system provides a sealed flexible gel pack for heating or cooling an injured part when placed in the pocket. The pack is internally baffled to evenly apply a compress therapy by restriction motion of the contents.

The invention relates to a balloon catheter in which the balloon is mounted on the end of the catheter in a manner that creates a recess or pocket between the catheter wall and balloon wall. The recess or pocket opens toward the proximal end of the catheter. The rigid end of an introducer element or finger is received in the recess to attach it to the catheter. The distal end of the catheter, with the end of the introducer element in the recess, is inserted and positioned within the bowel by manipulating the introducer element or finger. After the catheter is properly positioned in the bowel, the introducer element or finger is withdrawn, detaching it from the catheter as the end of the introducer element slides out of the recess and then out of the bowel. The balloon is inflated prior to or after the withdrawal of the introducer element to anchor the end of the catheter in position within the bowel. Since the distal end of the catheter is made entirely of soft, compliant material, no soft tissue damage can occur from use of the device, even when the catheter remains in place within the body over an extended time period.

A pressure monitoring method and system for warning a patient or caregiver that soft tissue pressure has exceeded some predetermined level that over time would necessitate moving the patient to minimize or prevent soft tissue damage. The method and system entail the use of a pressure-sensitive pad assembly adapted to be applied to a surface of the patient's body and generate electrical outputs corresponding to soft tissue pressure sensed at the surface. The system monitors the electrical outputs over a preselected time period and generates a cumulative output signal based on the electrical outputs and corresponding to whether or not the soft tissue pressure has exceeded a predetermined pressure level during the preselected time period. The system generates audible and visual warnings if the cumulative output signal exceeds a predetermined cumulative threshold until the soft tissue pressure drops below the predetermined pressure level.

Pressure monitoring methods and systems for warning a patient or caregiver that soft tissue pressure has exceeded some predetermined level that over time would necessitate moving the patient to prevent or at least reduce a risk of soft tissue damage. The methods and systems entail the use of a pressure sensing unit adapted to be applied to or near a surface of the patient's body, and a sensor associated with the sensing unit to generate electrical outputs corresponding to soft tissue pressure sensed at the surface. The electrical outputs are wirelessly monitored over a preselected time period to generate a cumulative output signal based on the electrical outputs and corresponding to whether or not the soft tissue pressure has exceeded a predetermined pressure level during the preselected time period. An alarm is generated if the cumulative output signal exceeds a predetermined cumulative threshold until the soft tissue pressure drops below the predetermined pressure level.

The present invention is a multi-purpose method and device comprising a therapeutic body containing a plurality of pins. The distal ends of the pins on the therapeutic body are placed in contact with the skin. The apparatus may be used to provide treatment to persons and animals suffering from the symptoms of soft tissue injuries in various regions of the body. The device and method is also useful for relaxation and reenergizing of an injured or tired body.

Minimal Invasive Spine Surgery (MISS) as a surgical approach is increasingly utilized because of the advantages it offers over conventional spine surgery. The smaller incision results in decreased tissue damage, less blood loss, decreased hospital stay & faster postoperative recovery. The drawbacks of MISS are the long learning curve of working through a smaller incision, longer length of surgery, & potential higher complication rate due to compromised visual field. These limitations can be overcome by more effectively using imaging and navigational devices. The pedicle device simplifies the hardest part of MISS instrumented fusion of conventional pedicle screw insertion by introducing a percutaneous temporary device to locate and create the channel for later conventional pedicle screw implantation using available imaging techniques. This results in faster conventional pedicle screw insertion with precision, thereby decreasing implantation error and minimizing soft tissue injury and blood loss, as well as neurological, vascular, and dural injuries and complications.

A wireless pressure ulcer alert dressing system for warning a patient or caregiver that soft tissue pressure or health condition has exceeded some predetermined level that over time would necessitate moving the patient to prevent or at least reduce a risk of soft tissue damage. The dressing assembly is adapted to be applied to or near a surface of the patient's body and generate electrical outputs corresponding to soft tissue pressure and other health characteristics sensed at the surface. The dressing assembly generates output signals based on the electrical outputs and corresponding to whether or not the soft tissue pressure has exceeded a predetermined pressure level during the preselected time period. The dressing assembly includes a pocket formed therein for removable, secured and protected insertion of a variety of different sensors such as multiple pressure sensors.
