Anchors for bodily implants and methods for anchoring bodily implants into a patient's body

摘要

An anchor is provided for anchoring a bodily implant within a body of a patient. The anchor includes an implant engaging portion for engaging the bodily implant, wherein the implant engaging portion is disposed on a lateral portion of the anchor. The anchor further includes a distal end portion configured to pass through a passageway in the patient's body, the passageway defining a first axis and a proximal end portion disposed longitudinally opposite to the distal end portion on the anchor. The anchor defines a second axis extending from the distal end portion to the proximal end portion. The anchor is configured to rotate when a force is applied to the bodily implant such that the second axis defined by the anchor forms an angle with the first axis defined by the passageway.

1. An anchor for anchoring a bodily implant within a body of a patient, the anchor comprising:
a distal end portion configured to pass through a passageway in the patient's body, the distal end portion having a lumen defined therethrough, the passageway defining a first axis; a removable delivery lead extending through the lumen, the delivery lead configured to facilitate insertion of the anchor in the passageway; a proximal end portion disposed longitudinally opposite to the distal end portion on the anchor, the proximal end portion including a tilt control lead, wherein the anchor defines a second axis extending from the distal end portion to the proximal end portion, the second axis being substantially parallel with the first axis defined by the passageway when the anchor is inserted in the passageway; and a medial portion having an implant engaging portion for engaging the bodily implant, the implant engaging portion disposed on a lateral portion of the anchor, the implant engaging portion including a first protuberance and a second protuberance configured to engage the bodily implant, at least one of the first protuberance and the second protuberance being movable relative to a body of the anchor so as to engage the bodily implant, the tilt control lead extending from the proximal end portion, the tilt control lead being configured to facilitate rotation of the anchor in the passageway such that the second axis defined by the anchor is non-parallel with the first axis defined by the passageway to help secure the anchor in the passageway.
