Abstract:
A method for dissecting a myoma from a uterine wall includes inserting a myomectomy screw retractor into a surgical site, articulating a tool assembly positioned at a distal end of the myomectomy screw retractor such that a screw of the tool assembly is positioned adjacent to the myoma orthogonal to the uterine wall, rotating the screw of the tool assembly into the myoma until the screw is substantially engaged with the myoma, manipulating the myoma by pitching, rotating, and/or providing traction to the myoma to expose cutting planes, and dissecting the myoma from the uterine wall by cutting along the exposed cutting planes.
Abstract:
A method for detaching an object from a patient includes providing a tool having a sheath, and a separating assembly operably coupled to a distal end of the sheath. The separating assembly includes a separator moveably coupled to a tip via a threadable connection. The separating assembly is placed near patient tissue that is attached to the object, the sheath is rotated to move the separator distal to the tip, and the separator is applied to the patient tissue that is attached to the object, so as to separate the tissue. A separating system includes a sheath, and a separator threadably coupled with a distal end of the sheath. The separator is adapted to switch between a first configuration where a separating means is deployed, and a second configuration where the separating means is undeployed.
Abstract:
A system for an anatomical joint includes a first fastener, a second fastener, a prosthetic ligament member, and a biasing member associated with at least one of the first and second fasteners. The first fastener is operable to be connected to a first bone portion. The second fastener is operable to be connected to a second bone portion. The prosthetic ligament member is flexible and is directly coupled to both the first and second fasteners to support the first bone portion and the second bone portion for relative movement. A portion of the prosthetic ligament member extends from the first fastener to the second fastener and has an adjustable length. The biasing member is operable to bias the prosthetic ligament member to thereby maintain tension in the prosthetic ligament member.
Abstract:
Embodiments of the invention relate to a catheter having an ultrasound energy emitting region that is both rotatable about and slidable along the shaft of the catheter. One embodiment is directed to a catheter comprising an ultrasound transducer coupled to the shaft, and at least one actuator coupled to the handle and the ultrasound transducer that is adapted to move the ultrasound transducer both longitudinally along the shaft and circumferentially about the shaft. Another embodiment of the invention is directed to a catheter comprising an ultrasound transducer coupled to the shaft, and at least one actuator that is adapted to move the sheath both longitudinally along the shaft and circumferentially about the shaft to orient a window of the sheath in a desired position.
Abstract:
A volume of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of a volume can be determined based upon the sensing of the plurality of points without the use of other imaging devices. An implantable medical device can then be navigated relative to the mapping data.
Abstract:
The various embodiments of the present inventions provide stabilization devices and methods for use of the stabilization devices with minimally invasive gynecological procedures such as methods of preventing pregnancy by inserting intrafallopian contraceptive devices into the fallopian tubes
Abstract:
According to one embodiment, an attachment/detachment mechanism detachably fixes an insertion member and an outer sheath member. The mechanism includes a removal preventing member and a rotation preventing member. The removal preventing member is configured to restrict movement of the insertion member inserted in the outer sheath member relative thereto in a removing direction. The rotation preventing member is configured to restrict movement of the insertion member inserted in the outer sheath member relative thereto in a rotating direction.
Abstract:
A surgical stapler that may have a head assembly, a stapling assembly, a shield, a base head, a handle assembly, and a shaft assembly. A head assembly may have an anvil and anvil shaft, as well as a stapling assembly. A stapling assembly may have a trocar that can be removeably detachable with the anvil, a cannula extension, and a plurality of staples. A shield may be configured to retract from a first extended position where the shield generally covers the stapling assembly or the head assembly, to a second retracted position where the shield generally exposes the stapling assembly or the head assembly. The shield may be integral with the stapler, or provided after-market as an add-on. A surgical stapler may additionally or alternatively include an air or gas pump assembly that can be used to insufflate the rectum and intestinal tract during insertion and advancement of the stapler.
Abstract:
A tissue fixation apparatus can include a flexible construct and an elongated locking member. The flexible construct can include at least two adjustable loops and tensioning members. The two adjustable loops can be configured to pass through the first tissue, and to be spaced apart along an outer surface of the first tissue in a first direction. The tensioning members can extend from the two adjustable loops, and can be configured to reduce the two adjustable loops from a first size to a second size. The flexible construct can be attached to the second tissue by an anchor. The locking member can be configured to be received within the two adjustable loops at the first size, and to engage the two adjustable loops at the second size.
Abstract:
A delivery device (suture passer or suture snare) that may be used in both open and endoscopic surgical procedures. The delivery device is designed with an internal member terminating in a snare and a retractable outer sheath (sleeve). The device is passed through tissue, and the outer sheath is retracted (moved back), allowing the snare to open. The suture is captured by the snare, and the outer sheath is then released so that it returns to its distal position, closing the snare and securing the captured suture. Since the snare is exposed by retracting the outer sheath (sleeve), rather than advancing the snare, the space requirement for the device is reduced, as is the possibility that the snare will undesirably contact sensitive tissue.
