摘要:
An adjusting and cutting tool comprising a distal end engageable with an elongate portion of an implantable article to facilitate manipulation of the elongate portion relative to a support portion of the implantable article and to facilitate cutting of the elongate portion. Also included is method of treating vaginal prolapse, the method including the steps of providing a multi-piece implantable article having at least one extension portion piece and a support portion piece, placing the support portion piece in contact with vaginal tissue, placing at least one extension portion piece in contact with tissue of a component of sacral anatomy, adjusting a position of the at least one extension portion piece relative to the support portion piece using a adjusting and cutting tool, and cutting the at least one extension portion with the adjusting and cutting tool.

A combined dissection tool and blank for implanting a paddle lead having an electrode portion and a lead body. The combined dissection tool and blank includes a blank with a maximum cross-sectional area substantially equal to a maximum cross sectional area of the electrode portion of the paddle lead. An elongated body portion is attached to the blank. A guide wire extends through the body portion substantially to a distal end of the blank. The guide wire provides sufficient column strength to separate fatty tissue to create a space for receiving the paddle lead.
摘要:
The present methods, systems, and kits permit the induction of multimodal injury to a subject's skin. This approach maximizes the responsiveness of the treated area to treatments for producing hair follicles; exciting, activating, and dispersing existing hair-producing structures; and bringing about other physiological changes that correspond to increased hair growth and/or the growth of more robust hairs. In contrast with conventional methodologies, the present methods and systems provide heretofore unattainable advantages through use of a multi-pronged approach of de novo hair follicle production, in combination with reorganization of existing structures to produce new follicular units, as well as pharmaceutical enhancement of both processes, and other gainful techniques.

A method of implanting a hearing prosthesis in a recipient, including boring an artificial passageway into the temporal bone to a middle ear cavity based on a virtual model of at least a portion of a recipient's temporal bone.
摘要:
A single use lancet device having a housing, with an open interior and an access opening defined therein, a lancet, with a body and a piercing tip, and disposed in the open interior of the housing so as to move between a cocked orientation and a piercing orientation, a driving assembly structured to move the lancet into the piercing orientation, and a restrictor assembly having a shoulder element and a restrictor panel operatively associated with the lancet and the housing and structured to pass over the restrictor panel upon the lancet moving from its cocked orientation to its piercing orientation, and to abut the restrictor panel upon attempted movement of the lancet back into its cocked orientation after movement into the piercing orientation, thereby preventing the lancet from moving back into the cocked orientation and preventing re-use of a contaminated piercing tip.
摘要:
The present disclosure provides methods and systems for increasing hair growth in subjects in need thereof due to male- or female-pattern hair loss, pathological hair loss, or hair loss after injury. By any use of any appropriate mechanical, electromagnetic, or chemical means, the present disclosure pertains to the segmentation of hair follicles into two or more disunited subunits in order to form new follicles from the respective subunits. In contrast with known techniques for bisecting hair follicles and as described more fully herein, the present methods and systems permit the bisection of single follicles or populations of follicles with a high degree of efficiency, and thereby represent an effective treatment option for those in need of increased hair growth.
摘要:
A method for constructing an instrument with a two-part plunger for subcutaneous implantation is provided. An incising body is formed by defining a non-circular coaxial bore and sharpening a distal bottom edge. A two-part plunger including a tongue blade assembly and a plunger assembly is constructed. The tongue blade assembly is constructed by sharpening a beveled end of a flat thin tongue blade and by affixing a straight tongue blade shaft to an end of the tongue blade opposite the beveled end. The tongue blade assembly has a length exceeding the coaxial bore. The plunger assembly is constructed by affixing a plunger to a plunger shaft on a distal end. The plunger assembly has a length exceeding the coaxial bore and is oriented adjacent to the tongue blade assembly. The two-part plunger is inserted through an end of the incising body.
摘要:
Transcutaneous devices are disclosed that self-provide cues for exact location of transcutaneous insertion sites, exit sites, and/or the track of the device between the sites, as are methods and kits for using the transcutaenous devices to mark the sites and track of the device and for removing location cues.
摘要:
A medical device for creating and closing an opening through a vessel wall is described. The device includes a guiding engagement element positioned in a vessel wall; an incising member positionable over the engagement element; and a cutting element, with a recessed notch, at a distal end of the incising member. The cutting element forms a flap on a first portion of a vessel wall, the flap having a first portion attached to the wall and second portion having a first diameter cut and a second diameter cut larger than the first diameter cut. The engagement element includes a retaining element engaging a portion of the flap; and an anchoring element engaging an external surface of the vessel, wherein the retaining element and the anchoring element exert a compressive force on the vessel wall for assisting closure of the cut.
摘要:
A surgical instrument (1) for performing controlled myotomies, particularly for performing internal anal sphincterotomies, comprises a proximal handle portion (2), an elongate insertion shaft (3) connected with the handle portion (2) and extending distally therefrom, a distal incision tip (4) arranged at a distal end of the insertion shaft (3) and adapted to incise tissue distally to the insertion shaft (3), a lateral incision member (5) arranged at the insertion shaft (3) and adapted to incise tissue laterally to the insertion shaft (3), wherein the lateral incision member (4) is movable from a rest position, in which it is retracted towards or inside the insertion shaft (3) and an operational position in which it protrudes laterally from the insertion shaft (3).
