摘要:
According to an embodiment, an inserter for installing a medical device via rotation in a recipient is disclosed. The inserter includes a longitudinal member adapted to rotate around a member axis, the longitudinal member comprising a first end and a second end. A grip unit at the first end is provided. The grip unit is adapted to grip the medical device. A shank member proximal to the second end is also provided. The shank member is adapted to engage with a drive unit that is adapted to provide a rotational force to the longitudinal member such that the gripped medical device is rotated around the member axis. The inserter includes an indicator unit adapted to provide a visual indication of number of turns of the longitudinal member when driven by the drive unit.

A catheter, advanced toward an anatomical site, has a proximal end and a steerable distal end. An anchor is advanced through the catheter. An anchor driver drives the anchor out of the catheter's distal end, anchoring the anchor at the site. A first constraining member engages tissue, and inhibits, after the anchor has been driven out of the catheter and before the anchoring, movement of at least the anchor driver's distal end, on a first axis between the anchor driver's distal end and a site at which the first constraining member engages the tissue. A second constraining member inhibits, after the anchor has been driven out of the catheter and before the anchoring, movement of at least the anchor driver's distal end, on a second axis. Other embodiments are also described.

The present invention relates to a guiding needle for a suction tube, which is for increasing accuracy and preventing medical accidents by enabling an operator to accurately recognize the bent direction of the needle and to stably hold the needle by means of a handle portion formed inside the rear end of the needle connected to a tube or by means of a separate fixing handle coupled to the inside of the rear end of the needle. In other words, the present invention relates to a needle having the rear end thereof coupled to one end of a tube connected to a drainage container for discharging body blood of a patient, wherein the needle has a coupling part formed inside the rear end thereof and comprises a fixing handle detachably coupled to the coupling part.

An endoscopic treatment instrument includes a guide pipe and a guide sheath. The guide pipe through which the insertion portion is inserted so that a distal side of a distal end of the insertion portion and a distal side of a first distal end are observable through the first distal end by the observation optical system of an endoscope or so that the distal side of the distal end of the insertion portion is observable by the observation optical system while the distal end of the insertion portion is protruded relative to the first distal end. The guide sheath has an inside diameter to insert the insertion portion therethrough so that the distal end of the insertion portion is configured to protrude relative to the second distal end and is inserted through the guide pipe so that the second distal end is configured to protrude relative to the first distal end of the guide pipe.

The invention relates to a rotational position determination apparatus (15) for determining an entry rotational position, which defines a rotational position of an insertion device like a stent at an entry site (5), such that a navigation of the insertion device from the entry site to a target site (6) along an inner path (8) results in a rotational position of the insertion device at the target site being equal to a desired target rotational position based on a representation of the inner path and the desired target rotational position. If the insertion device is arranged in the determined entry rotational position at the entry site and then navigated to the target site, it is therefore not necessary to rotate the insertion device at the target site, i.e. it is not necessary to use a technically complex interventional device for rotating the insertion device at the target site.
摘要:
A surgical cutting instrument including a first tubular member, a second tubular member, a sleeve member, a third tubular member, and an orientation member. A distal section of the first tubular member includes a cutting tip. The distal region of the second tubular member forms a cutting window. The first elongated member is co-axially disposed within the second tubular member such that the cutting tip is selectively exposed at the cutting window. The first and second tubular members are co-axially disposed within the sleeve member. The third tubular member is co-axially disposed around the intermediate section of the first tubular member, the intermediate region of the second tubular member and the sleeve member. The orientation member is rotatable to transmit a rotational force applied to the orientation member to selectively rotate the second and third tubular members relative to the sleeve to effectuate spatial rotation of the cutting window.

An assembly includes a catheter that has an insemination lumen for injecting sperm into a uterus. The insemination lumen includes two branches (sub-lumens), one directed toward a left ostium and the other directed to a right ostium of fallopian tubes.
摘要:
A tissue anchor has a body, protrusions from the body, and a tissue engaging fin. The body is oriented on a longitudinal axis and has a leading tip, a leading end portion extending from the leading tip, a trailing end portion connected to the leading end portion, with the trailing end portion terminating in a trailing tip that is located opposite of the leading tip. A first anchor width measured between the protrusions is greater than a second anchor width measured at the trailing end portion of the body. The tissue engaging fin is integrated with the leading end portion of the body and oriented in a direction perpendicular to the radial direction of the first and second protrusions. The tissue engaging fin has a fin width and is provided with an eyelet formed through the fin width. A gripping tab is removably attached to the tissue engaging fin.
