Clinical Evaluation of the Interlace Medical Hysteroscopic Morcellator

November 20, 2012 updated by: Hologic, Inc.

Retrospective Case Review - Clinical Evaluation of the Interlace Medical 1st Generation Hysteroscopic Morcellator

This study assesses the effectiveness of intrauterine fibroid and polyp removal using the Interlace Medical 1st generation hysteroscopic morcellator device based on a retrospective review of medical records of women who have been treated with the device.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A retrospective review of medical records for eleven (11) premenopausal women who had been treated with the new hysteroscopic morcellator was conducted at four hospital or ambulatory surgical center sites. Four physicians performed hysteroscopic operative procedures to remove intrauterine polyps, type 0 (completely within the uterine cavity), type I (mostly within the cavity) and type II (< 40% within the cavity) submucous myomas. Percent pathology removed, total morcellation time, total fluid used, fluid deficit and treatment-related adverse events were assessed. Each of the four treating physicians also evaluated device performance using a 10 point scale (1 = "poor" and 10 = "excellent").

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Hysteroscopic Morcellator
11 women previously receiving hysteroscopic myomectomy or polypectomy using the hysteroscopic morcellator device.
Device: Interlace Medical 1st Generation Hysteroscopic Morcellator
The Interlace Medical hysteroscopic morcellator system has been cleared by the FDA(K073690)and consists of a motor drive unit connected to a 3mm morcellator. The morcellator is approximately 12 cm long and is equipped with an open channel that houses a reciprocating blade. When the motor is activated, the reciprocating blade will cut the tissue within the channel. The tissue travels down the 3mm morcellator shaft cannula via suction coupled to the proximal end of the morcellator and is captured in a tissue trap in a suction canister for pathological diagnosis following the procedure.

  • MyoSure Tissure Removal System
  • MyoSure Tissure Removal Device

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Tissue Removed
Time Frame: immediately post-treatment
mean percentage of polyp and fibroid tissue removed, as measured on post-treatment hysteroscopic imaging. Images were obtained immediately post treatment, before the subject left the surgical suite.
immediately post-treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Treatment Time Per Patient
Time Frame: at time of treatment
mean morcellation(division into and removal of small pieces, as of tissue) time per patient
at time of treatment
Fluid Volume Per Procedure
Time Frame: at time of treatment
mean volume of distension fluid infused into the uterus, per procedure. Distention fluid is used to distend the uterus and provide increased visibility.
at time of treatment
Fluid Deficit Per Procedure
Time Frame: at time of treatment
mean fluid deficit per procedure. Fluid deficit is the difference between the amount of fluid which is infused into the patient during the hysteroscopic procedure, and the amount of fluid collected at completion of the procedure.
at time of treatment
Resected Tissue Weight Per Patient
Time Frame: at time of treatment
mean weight of resected tissue per patient
at time of treatment
Interlace Medical 1st Generation Hysteroscopic Morcellator Cutting Ability - Mean Score
Time Frame: 2-3 months post treatment
a 10 point scale assessed performance of the Interlace Medical 1st Generation Hysteroscopic Morcellator("1" = "poor" and "10" = "excellent").
2-3 months post treatment
Adverse Events
Time Frame: 2-3 months post-treatment
Patient medical records were examined to identify any procedure-related or post-treatment adverse events. An adverse event is any undesirable experience (sign, symptom, illness, or other medical event) occurring in a subject, that appears or worsens during a clinical study
2-3 months post-treatment

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
