MEDICAL CLIP AND METHOD FOR PRODUCING A MEDICAL CLIP

A medical clip includes first and second clamping arms and a biasing element. The first clamping arm is connected to a first end of the biasing element, and the second clamping arm is connected to a second end of the biasing element. The first clamping arm and the second clamping arm are maximally proximate to one another in a basic position of the clip and are movable away from one another against the action of the biasing element from the basic position into an opening position. The medical clip is made partially by a generative manufacturing process, in which the medical clip has at least one first clip portion and at least one second clip portion. The at least one second clip portion is formed directly onto the at least one first clip portion by a generative manufacturing process.

DEVICES, SYSTEMS, AND METHODS FOR POSITIONING AN ANCHOR FOR AN ARTIFICIAL CHORDAE TENDINEAE

Implantable devices formed of materials which are not readily imageable, and which may shift from a delivery configuration to a deployment configuration upon deployment, are delivered and deployed with a deployment/delivery device having sensors generating a signal indicating contact of the delivery/deployment device with tissue to guarantee purchase of the implantable device with tissue upon deployment. The implantable device may be a tissue anchor with talons which shift from a delivery configuration to a deployed configuration. The sensors may be positioned along a distal end of the delivery/deployment device to indicate purchase of the device with tissue, to ensure purchase of the talons with tissue upon deployment. The sensors may include at least three sensors, which may be spaced apart from one another, to indicate full contact of the distal end of the delivery/deployment device with tissue. The sensors may optionally be aligned with the talons.

IMPLANTABLE SPHINCTER ASSISTANCE DEVICE WITH BIMODAL CIRCUMFERENTIAL RESTRICTION FORCE THRESHOLD

An apparatus includes a plurality of beads and a plurality of interconnection elements. Each bead includes a housing and a magnet. Each interconnection element includes a main body extending between a pair of ends, and a pair of heads each positioned at a respective end and received within a bead. The beads and interconnection elements are sized and configured to form a loop configured to transition between constricted and expanded configurations. The apparatus is configured such that, when the loop is in the expanded configuration, a first head of a first interconnection element is received within a first bead and is spaced apart from a first centerline of the first bead by a first distance, and a second head of a second interconnection element is received within a second bead and is spaced apart from a second centerline of the second bead by a second distance.

Partially oval capsule for reloadable hemostasis clipping device

A system for treating tissue includes an applicator having a bushing and a control member and a clip assembly having a capsule with a channel extending therethrough. The channel includes proximal and distal portions. The distal portion extends distally from the proximal portion and flaring outward in a single plane to form opposing flared sections. The assembly also includes clip aims include proximal ends slidably received within the channel to move the arms between tissue receiving and tissue clipping configurations. The assembly further includes a yoke including a distal portion connected to the arms and a proximal portion configured to be connected to the control member so that longitudinal movement of the control member relative to the capsule moves the arms between the tissue receiving and clipping configurations. The yoke is positioned in the capsule so that the yoke is deformable in the plane in which the capsule flares outward.
