Bone repair system and method
A bone repair system and method for percutaneously fixing a first bone segment to a second bone segment, such as rib bone segments, in a body of a patient include drilling a first hole through the first bone segment and a second hole through the second bone segment, and feeding a first tether through the first hole and a second tether through the second hole, each tether having a proximal end and a distal end. The first and second tether distal ends are withdrawn from the body while the first and second tether proximal ends have not passed through the first and second bone segments, respectively. A reinforcing member, such as a bone plate, having first and second openings, is passed onto the first and second tether distal ends, and the reinforcing member is pulled into engagement with the first and second bone segments guided by the tethers. The reinforcing member is secured to the first bone segment with a first fastener assembly through the first hole and the first opening and to the second bone segment with a second fastener assembly through the second hole and the second opening to fix the first bone segment to the second bone segment.
Assembly for placement of a cardiac, aortic or arterial implant with stimulation assistance by a peripheral venous or arterial catheter
An assembly for placement of a cardiac, aortic or arterial implant. The assembly includes an insertion sheath of an introducer or of a delivery catheter, which is of a size smaller than that of an introducer, intended to be introduced into an artery of a human body. The metal support of an electrode of the external cardiac stimulator being integrated into the insertion sheath of a peripheral venous or arterial accessory catheter, or a sleeve around the accessory catheter, which is introduced into the peripheral vein or artery of a patient. The sheath of the accessory catheter or the sleeve is therefore directly in contact with a peripheral vein or artery of the patient.
APPARATUSES FOR THE IMPLANTATION OF MEDICAL DEVICES AND METHODS OF USE THEREOF
A medical device may include a shaft extending between a proximal end and a distal end. The shaft may include a lumen therein. The medical device may include a handle coupled to the proximal end of the shaft and may include a mode selector. The mode selector may be adapted to transition between a first mode and a second mode of the medical device. The medical device may further include a compressed fluid source. In the first mode, the compressed fluid source may be fluidly coupled with the shaft so as to impart a negative pressure in at least a portion of the lumen. In the second mode, the compressed fluid source may be fluidly coupled with the shaft so as to impart a positive pressure in the at least a portion of the lumen.
METHOD OF SURGICAL STAPLING WITH END EFFECTOR COMPONENT HAVING A CURVED TIP
A method of surgical stapling that uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.
EXPANDABLE TISSUE ENGAGEMENT APPARATUS AND METHOD
A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes an expandable structure for enhancing engagement with median lobe prostate tissue.
METHODS OF IMPLANTING A STIMULATION LEAD FOR STIMULATION OF A DORSAL ROOT
In one embodiment, a method of implanting a stimulation lead to stimulate a dorsal root ganglion (DRG) of a patient, comprises: placing a distal portion of the stimulation lead within an implant tool; accessing the epidural space of the patient with the distal end of the implant tool; contacting a surface of a pedicle of the patient with a distal tip of the implant tool above a foramen leading to a target DRG; after contacting the surface of the pedicle with the distal tip, advancing the stimulation lead from a side port of the implant tool, wherein the side port is located proximal to the distal tip of the implant tool; advancing the stimulation lead through the foramen to position one or more electrodes of the stimulation lead adjacent to the target DRG; and providing electrical stimulation to the target DRG to stimulate the target DRG using one or more electrodes of the stimulation lead.
Implantable medical system
The invention provides an implantable system for managing urinary incontinence. The system includes a sling with an elongate body member having a proximal portion, a distal portion and an intermediate portion. The intermediate portion is configured to be positioned underneath urethra of a subject for providing an adequate support to prevent leakage of urine during a stress event. The system may include a pressure sensor communicatively coupled with the elongated body member and configured to be positioned in an abdominal cavity and adapted to sense an increase in intra-abdominal pressure. The pressure sensor generates a first signal that is indicative of a change in the intra-abdominal pressure upon occurrence of the stress event. The system includes a processing circuit to process the first signal sensed by the pressure sensor. The processing circuit is configured to generate a second signal causing an adjustment of tensioning force in the elongate body member thereby changing magnitude of a supporting force to the urethra.
Surgical cannula with removable pressure seal
The present disclosure relates to a surgical cannula with a removable seal at one end. The surgical cannula is a wide gauge surgical cannula, that allows materials and tools to be introduced into a body during a surgical procedure. The cannula includes a seal structure at one end, which may be attached to and detached from the cannula body as desired. The seal structure includes one or more valves that retain pressure within the cannula. The one or more valves are configured to allow a tool through the valve(s), while retaining pressure inside the cannula, so that surgical tools may be inserted through the cannula even when the seal structure is attached to an end of the cannula.
Systems and methods for implanting electrode leads
Disclosed herein are systems and methods for insertion tools for implanting electrode leads. In one embodiment, an insertion tool comprises a shaft having an outer cannula and an inner cannula. An actuator may be configured to transition the insertion tool between at least three configurations. In a first configuration, the inner cannula and the outer cannula are configured to receive the lead in the shaft. In a second configuration, the inner cannula and the outer cannula are configured to secure the lead in the shaft. In a third configuration, the inner cannula and the outer cannula are configured to cause the lead to separate from the insertion tool and implant in adjacent tissue.
DEVICE FOR MENISCAL REPAIR
The present disclosure relates to a device for meniscal repair for use in areas of a human body where tissue can either be surgically reattached to bone or surgically repaired when a tear forms in the tissue. The device may take one of three forms; in a first form, the device comprises a handle and a deployment member permitting the deployment of anchors or sutures to the tissue requiring repair; subsequently the device may take a second form comprising the handle, still in place, and a cutter member for manipulating and cutting anchors and sutures to assist in repair of the tissue; in its third form, the device comprises the handle, still in place, and a fluid injection member for applying a fluid to aid in improving biological conditions for the tissue to heal.
